High School Football Rules Changes
40-Second Play Clock, State Option for Postseason Instant Replay Among Changes in High School Football
INDIANAPOLIS, IN (February 11, 2019) — In an effort to establish a more consistent time period between downs in high school football, the play clock will start at 40 seconds instead of 25 seconds in many cases beginning with the 2019 season.
This change was one of seven rules revisions recommended by the National Federation of State High School Associations (NFHS) Football Rules Committee at its January 13-15 meeting in Indianapolis, which were subsequently approved by the NFHS Board of Directors.
The play clock will continue to start at 25 seconds (a) prior to a try following a score, (b) to start a period or overtime series, (c) following administration of an inadvertent whistle, (d) following a charged time-out, (e) following an official’s time-out, with a few exceptions, and (f) following the stoppage of the play clock by the referee for any other reason. In all other cases, 40 seconds will be placed on the play clock and start when the ball is declared dead by a game official.
Previously, the ball was marked ready-for-play when, after it had been placed for a down, the referee gave the ready-for-play signal and the 25-second count began. Beginning next season, in addition to the above situations when the 25-second count is used, the ball will also be ready for play when, starting immediately after the ball has been ruled dead by a game official after a down, the ball has been placed on the ground by the game official and the game official has stepped away to position.
“The entire committee needs to be commended for its thorough discussion regarding the move to a 40-second play clock, except in specific situations that will still have a 25-second play clock to show play is ready to begin,” said Todd Tharp, assistant director of the Iowa High School Athletic Association and chair of the NFHS Football Rules Committee. “This is one of the most substantial game administration rules changes to be approved in the past 10 years, and without detailed experimentation from several state associations over the past three years, along with cooperation of the NFHS Football Game Officials Manual Committee, all the elements needed to approve this proposal would not have been in place.
Another significant change approved by the committee was the addition of a note to Rule 1-3-7 to permit state associations to create instant-replay procedures for state postseason contests only. This revision would allow game or replay officials to use a replay monitor during state postseason contests to review decisions by the on-field game officials. Use of a replay monitor would be on a state-by-state adoption basis, and the methodology for reviewing calls would be determined by the applicable state association.
“The ultimate goal of each game official and each officiating crew is to get the call correct,” Tharp said. “Each state association, by individual adoption, can now use replay or video monitoring during its respective postseason contests to review decisions by the on-field game officials. Each state association, if it adopts this rules revision, will also create the parameters and scope of the replay.”
With regard to uniforms, the NFHS Football Rules Committee clarified the size requirements for numbers on jerseys through the 2023 season and added a new requirement effective with the 2024 season. Clarifications to Rule 1-5-1c (in bold) that are in effect through the 2023 state that the numbers, inclusive of any border, shall be centered horizontally at least 8 inches and 10 inches high on front and back, respectively. In addition, the entire body of the number (the continuous horizontal bars and vertical strokes) exclusive of any border(s) shall be approximately 1½-inches wide. Finally, through the 2023 season, the body of the number (the continuous horizontal bars and vertical strokes) shall be either: (a) a continuous color(s) contrasting with the jersey color; or (b) the same color(s) as the jersey with a minimum of one border that is at least ¼-inch in width of a single solid contrasting color.
Effective with the 2024 season, the entire body of the number (the continuous horizontal bars and vertical strokes) of the number shall be a single solid color that clearly contrasts with the body color of the jersey.
“The purpose of numbers on jerseys is to provide clear identification of players,” said Bob Colgate, NFHS director of sports and sports medicine and staff liaison to the NFHS Football Rules Committee. “In order to enhance the ability to easily identify players, the committee has clarified the size requirements for jersey numbers through the 2023 season and added a new requirement for the 2024 season.”
Two changes were approved by the committee in an effort to reduce the risk of injury in high school football. First, tripping the runner is now prohibited. Beginning next season, it will be a foul to intentionally use the lower leg or foot to obstruct a runner below the knees. Previously, a runner was not included in the definition of tripping. Second, in Rule 9-4-3k, the “horse-collar” foul was expanded to include the name-plate area, which is directly below the back collar. Colgate said grabbing the name-plate area of the runner’s jersey, directly below the back collar, and pulling the runner to the ground is now an illegal personal contact foul.
A change in the definition of a legal scrimmage formation was approved. A legal scrimmage formation now requires at least five offensive players on their line of scrimmage (instead of seven) with no more than four backs. The committee noted that this change will make it easier to identify legal and illegal offensive formations.
The final change approved by the NFHS Football Rules Committee for the 2019 season was a reduction in the penalty for illegally kicking or batting the ball from 15 yards to 10 yards.

According to the 2017-18 NFHS High School Athletics Participation Survey, 11-player football is the most popular high school sport for boys with 1,036,842 participants in 14,079 schools nationwide. In addition, there were almost 30,000 boys who participated in 6-, 8- and 9-player football, along with approximately 2,500 girls who played the sport for a grand total of 1,068,870.
2019 NFHS FOOTBALL RULES CHANGES
BY STATE ASSOCIATION ADOPTION, USE OF VIDEO REVIEW ALLOWED FOR STATE POST-SEASON CONTESTS [1-3-7 NOTE (NEW), TABLE 1-7 – 1-3-7 NOTE (NEW)]
Rationale: By state association adoption, instant replay may only be used during state postseason contests to review decisions by the on-field game officials. This adoption would allow state associations to develop protocols for use of video replay.
IMPROVED VISIBILITY OF NUMBERS [1-5-1c, 1-5-1c(6) (NEW)]
Rationale: The purpose of numbers on jerseys is to provide clear identification of players. In order to enhance the ability to easily identify players, the committee has clarified the size requirements for jersey numbers through the 2023 season. The committee also added a new requirement that, effective in the 2024 season, jersey numbers must be a single solid color that clearly contrasts with the body color of the jersey.
REDEFINED REQUIREMENTS FOR A LEGAL SCRIMMAGE FORMATION [2-14-1, 7-2-5a]
Rationale: A legal scrimmage formation now requires at least five offensive players on their line of scrimmage with no more than four backs. This change will make it easier to identify legal and illegal offensive formations.
PROHIBITION ON TRIPPING THE RUNNER [2-45, 9-4-3o (NEW), 9-4-3o PENALTY (NEW)]
Rationale: In an effort to decrease risk, tripping the runner is now prohibited. It is now a foul to intentionally use the lower leg or foot to obstruct a runner below the knees.
40-SECOND PLAY CLOCK [2-35-1, 3-6-1, 3-6-2a, 7-2-1]
Rationale: To have a more consistent time period between downs, the rules committee approved situations where 40 seconds will be placed on the play clock. The new rule defines when 40 seconds will be placed on the play clock and when 25 seconds will be placed on the play clock.
HORSE-COLLAR TACKLE ADDITION [9-4-3k]
Rationale: Grabbing the name plate area of the jersey of the runner, directly below the back collar, and pulling the runner to the ground is now an illegal personal contact foul.
ILLEGAL KICKING AND BATTING PENALTY REDUCED [9-7 PENALTY]
Rationale: The penalty for illegally kicking or batting the ball was reduced from 15 yards to 10 yards.

Proper Wearing and Use of Required Equipment
Prior to the start of each game, the head coach must verify that all of his players have the proper equipment and that no illegal equipment will be used. The purpose of equipment rules is to ensure the safety and protection of both the player wearing the equipment and his opponent. Due to the potential for injury, game officials must strictly enforce equipment rules. Game officials have been reluctant to penalize a team for the failure of a player to properly wear all of the required equipment. This reluctance may be due to game officials assuming that equipment violations are a minor offense and do not warrant penalties. In view of this reluctance, a rule change has been implemented to lessen the severity of the consequence of violating equipment rules. With the lessened severity, it is imperative that game officials follow appropriate procedures when equipment violations occur. Equipment rules are an extremely important part of the game, and it is therefore essential that game officials are diligent in promptly addressing any and all equipment rule violations.
Equipment violations can be grouped into three categories: (1) failure to properly wear required equipment, (2) failure to wear or use legal and/or required equipment, and (3) wearing illegal equipment. The first category encompasses instances where the required equipment is present, but is not worn properly. Examples include, but are not limited to, unsnapped chin straps, tooth and mouth protectors that are dangling, or jerseys that do not fully cover the shoulder pads or back pads. If game officials observe any improperly worn equipment during a dead-ball period, they should declare an official’s time-out and ask the player to make a correction. However, if the equipment issue is not recognized until the snap is imminent, the game official should immediately sound his whistle to prevent the snap from occurring, declare an official’s time-out and require that the player leave the game for at least one down to address the equipment issue. The second category is when a player is missing any required equipment. In this situation, an official’s time-out must be declared, the player must leave the game for at least one down and will not be allowed to return to the game until the missing equipment is obtained and properly worn by the player. The third category occurs when a player wears illegal equipment. Examples include, but are not limited to, the wearing of cleats that exceed ½-inch, or the presence of a sticky substance on a player’s uniform. If a player is detected wearing illegal equipment, his head coach is charged with an unsportsmanlike conduct foul under Rule 9-8-1h.
If any equipment becomes illegal or defective during the game, correction must be made before the player continues to participate. Examples include chin-strap snaps which break off of the helmet or a jersey that slides up over the top of the shoulder pad. If the correction can be made without the assistance of a team attendant, and without delaying the ready-for-play signal by more than 25 seconds, an official’s time-out may be called to perform such correction. Alternatively, a team may request a charged time-out to perform the correction. However, if correction cannot be completed within 25 seconds, or during a charged timeout, the player may not continue to participate until correction is made.
Pace of Play and Timing Issues
In order to maintain a fair balance between offense and defense, a consistent pace of play should be established and maintained by the game officials during the entire contest. Each team should be allowed an equal opportunity to make substitutions and call plays during the time between the dead ball and the next ready-for-play signal. The pace of play should not change during the contest, and should be the same from game to game, and from officiating crew to officiating crew. Therefore, the committee recommends the ready-for-play signal be given between 12 and 15 seconds after the previous dead ball. This pace of play should be consistent no matter if either team wants to hurry up or slow down. Long incomplete passes, plays into the side zones and first downs may require the game officials to hustle to get the ball and line-to-gain equipment properly set, while short runs up the middle may require a slight delay before marking the ball ready for play. Consistency is the goal without regard to particular game situations.
To accomplish a consistent pace, the referee should develop a “feel” for 12 to 15 seconds. This feel can be accomplished in many ways. A few examples could be for a referee to establish a routine of duties to perform after each dead-ball whistle, then mark the ball ready-for-play after completing those duties. A referee could also use the game clock to time 12 to 15 seconds if it is running and easily observable. Lastly, a referee could ask an observer to record the amount of time between a dead-ball whistle and the next ready-for-play so pace -of-play adjustments can be made during their next contest. With some attention by the referee and effort by the entire officiating crew, consistent pace of play can be achieved.
In a similar fashion, game officials should also be vigilant about unfair use of the game clock. Rule 3-4-6 has been around for many years and allows the referee to start or stop the game clock when a team attempts to illegally conserve or consume time. This rule applies at any time during the contest including the last two minutes of either half. Game officials are encouraged to become “clock aware” at 4:00 in each half for potential illegal clock manipulation. Game officials should also be “clock aware” near the end of the first and third periods if weather conditions or field conditions could give a team an advantage through the delay or acceleration of the reversal of-field position at the end of each period.
In 2017, the NFHS Football Rules Committee adopted Rule 3-4-7 which gives an offended team the option to start the clock on the snap when a penalty is accepted with less than two minutes left in either half. This option applies to any accepted penalty by either team if the clock would otherwise start on the subsequent ready-for-play signal. In a situation where there is a live-ball foul by one team and a dead-ball foul by the other, or a dead-ball foul by both teams, each team would be given the option to start the clock on the snap if it would have otherwise started on the ready-for-play. If either team exercises this option, the clock will start on the snap. It is of no significance whether or not the clock was running at the time a foul occurred.
Enforcement of Penalties for Personal Fouls and Unsportsmanlike Conduct Fouls
Rule 9-4 provides a list of illegal personal contact fouls. These acts are illegal due to the potential for injury to an opponent. With a few notable exceptions, these fouls do not carry an automatic disqualification, although disqualification may result if the covering official judges the foul to be flagrant. Additionally, the penalties for repeated violations in the same game are not cumulative. For example, if a player pulls a ball carrier down by the face mask and later in the game commits a taunting foul, the player remains in the game. Unnecessary roughness fouls are personal fouls — not unsportsmanlike conduct fouls — and are not being included in the specific fouls that would lead to disqualification unless the act is flagrant.
Unsportsmanlike conduct fouls never involve contact with an opponent.
Game officials need to be aware of all circumstances before enforcing the distance penalty for a personal foul as there are several factors to be evaluated, such as the type of play (loose ball vs. running play), whether there was a change of possession, whether a score occurred during the play or whether a double foul or multiple fouls occurred.
Rules 9-5 and 9-8-1 define noncontact unsportsmanlike conduct and provide general examples of such fouls including using profanity, vulgar language or gestures, attempting to influence a game official’s decision, a coach allowing his players to use illegal equipment, being on the field except as a substitute or replaced player and several other situations.
Specific examples of unsportsmanlike conduct include but are not limited to the following: any delayed, excessive or prolonged act by which a player attempts to focus attention upon himself; using abusive, threatening or insulting language or gestures to opponents, teammates or game officials; or using baiting or taunting acts or words that engender ill will between teams.
Unsportsmanlike conduct fouls accumulate and any player or non-player who receives two such fouls is automatically disqualified from the contest. However, any single foul judged by the game official to be flagrant is disqualification. Unsportsmanlike conduct penalties are always enforced from the succeeding spot.
Situations have arisen in recent years regarding unsportsmanlike conduct that have not been correctly called. For example, the “Where’s the tee?” play described in the case book is an example of unsportsmanlike conduct. The ball should be declared dead and the penalty should be enforced as a dead-ball foul. Football has been and will continue to be a game of deception and trickery involving multiple shifts, unusual formations and creative plays; however, actions and language designed to confuse the defense into believing there is a problem and a snap isn’t imminent are beyond the scope of fair play.
Defenseless Player and Blindside Blocks
In 2017, the NFHS adopted rules defining and giving examples of defenseless players, and rules prohibiting forceful blindside blocks outside the free-blocking zone unless initiated with open hands. Coaches and game officials should understand, teach and apply these rules in a manner promoting player safety and minimizing the risk of player injury.
Defenseless Player — A defenseless player is one who, because of his physical position and focus of concentration, is especially vulnerable to injury. The most common types of defenseless players include passers, receivers, sliding runners, runners whose forward progress is stopped, players out of the play and players who are blindside blocked.
A defenseless player is not in an equal physical position with the player attacking him and could be severely injured when contacted. For example, a player passing or attempting to catch a ball is completely exposed to opponents. A player obviously out of the play has no reason to think an opponent will charge into him. A runner in an opponent’s grasp and whose forward progress has been stopped cannot defend himself from an opponent taking a free shot at him. A downed runner or a runner giving himself up and sliding feet first cannot protect himself against unnecessary contact. A player receiving a blindside block is unaware of the opponent charging him. What is common among all these situations is that the player cannot defend himself or avoid potential contact, leaving himself vulnerable to injury. Special attention must be given to contact against these players to determine if it is legal. Although defenseless players who are involved in the play may be contacted by an opponent, the player initiating contact must do so in a legal manner.
The term “defenseless player” is relatively new to the rules, but the protection afforded these players is not. For several years, the rules have penalized roughing the passer, kick catching interference, illegal helmet contact, unnecessary roughness and late hits. Classifying players as defenseless reinforces the prohibition against illegal contact and emphasizes the need to protect the most vulnerable players. Excessive and unnecessary contact, including forceful contact to the head or neck area of a defenseless player, has long been illegal, and it has no part in the game. Coaches must exercise leadership in eliminating illegal contact, and game officials must act decisively to penalize illegal contact to minimize the risk of player injury.
Blindside Blocks — A blindside block is an effective blocking technique. There is nothing improper in executing blindside blocks generally, and the rules do not preclude their use altogether. Instead, to enhance player safety and minimize the risk of injury, the rules prohibit a specific type of blindside block: one that is forceful, is not initiated with open hands and occurs outside the free-blocking zone.
A blindside block is a foul if: (1) the block occurs outside of the free-blocking zone; (2) the blocker does not initiate the block with open hands; and (3) the block is forceful. If all three of these factors are present, the blindside block is illegal.
Coaches should teach proper blindside blocking techniques, and game officials should evaluate whether a blindside block is legal, based on these three factors and the considerations below, as well as the underlying spirit and intent of the rules—to promote safety, eliminate illegal contact and minimize the risk of injury to players.
• Whether the player being blocked can see the block coming. A blindside block is “a block against an opponent other than the runner, who does not see the blocker approaching.” In other words, it is a block that the opponent does not see coming.
Game officials must first determine whether a block is a blindside block. Usually, this will be obvious. The player being blocked will be looking away from the blocker while being blocked from the side by an opponent. In some situations, however, the player being blocked may turn his head to see the blocker just before contact occurs. Such contact is still considered a blindside block. Though the player may have seen the blocker approach, he did not do so in sufficient time to have a reasonable opportunity to react, adjust and defend himself.
Some element of time, though it may be very short, is necessary to accomplish the rule’s safety purposes. In most situations, the blocker is running at full speed, increasing his momentum and focusing on one player. The player being blocked, however, is focused elsewhere and completely unaware of the charging blocker. Such a player who turns his head at the last second and sees his opponent just before contact cannot realistically protect himself. He is just as defenseless and vulnerable to injury as if he had not turned his head at all. Game officials should not be overly technical with this requirement and should always err on the side of player safety. The intent of this rule is to protect the player being blocked. It is not intended to create a legal way of throwing a shoulder or body block. When in question, the block is a blindside block.
• Whether the block occurred outside of the free-blocking zone. If a blindside block occurs in the free-blocking zone, it is legal even if the contact is forceful and even if it is not initiated with open hands. Of course, the contact must otherwise be legal—a player cannot clip or target an opponent, for example. However, the free-blocking zone exists only during scrimmage plays, and it disintegrates as soon as the ball leaves the zone. When the zone is gone, any blindside block by rule occurs outside of the free-blocking zone and, if forceful, must be initiated with open hands to be legal.
• Whether the block was initiated with the open hands. Any forceful blindside block outside the free-blocking zone must be initiated with open hands. Blocks initiated with the shoulder or body are dangerous because of the amount of force they generate. Blocks initiated with open hands are significantly less dangerous because they do not typically generate that same amount of force. The open-hands requirement is intended to reduce the force associated with blindside blocks.
As a result, game officials should consider two things in determining whether a blocker has complied with the open-hand requirement. First, the blocker’s initial contact with his opponent must be with open hands if the block is forceful. Second, the force of the block should come from the blocker’s hands and arms rather than from his shoulder or body.
A player who makes first contact with open hands and imparts a force to the opponent by extending his hands and arms has complied with this rule. However, a player who makes first contact with open hands but nonetheless forcefully drives his shoulder or body into his opponent has not complied with the rule. Instead, he has thrown a shoulder or body block with all the force that his shoulder and body carry. The open-hand requirement is meant to reduce that type of force. It is not intended to allow an otherwise illegal shoulder or body block simply by placing open hands on the opponent at the last second.
• Whether the block was forceful. If a player has thrown a non-open-handed blindside block outside the free-blocking zone, game officials must finally determine whether the block is forceful. If the block is forceful, it is a foul; if not forceful, it is not.
“Forceful contact” is something more than minor contact but something less than excessive contact. The contact should be significant enough to notice, but it does not have to be violent or otherwise unnecessary to be forceful. As an aid to judging whether a block is forceful, the covering official should consider whether the blocker was only attempting to take his opponent out of the play, or whether the block was intended to take the opponent out of the game. The former is legal, while the latter is illegal.
Game officials should take the entire block into consideration. The focus should be on the block itself and the blocker, because he is the player generating the force behind the block. The reaction of the player being blocked may help, but it is not the determining factor. Game officials should never base their decision on forceful contact solely on whether the player goes to the ground.
Where a blocker’s shoulder or body contact results in minor movement of the opponent and the force of the block is not obvious, the block is not forceful. However, where the blocker makes contact with some obvious degree of force behind the block, contact is forceful regardless of the effect on the opponent.
Finally, game officials should be diligent in observing these blocks and penalizing infractions. Although the rule applies throughout the game, blindside blocks are most likely to be made by the offense on returns following interceptions, free kicks and punts. They may also occur when the offense reverses direction on the field. Game officials must use proper mechanics on these plays and be in position to observe players throwing blindside blocks. The most likely offenders will be those doing something different from others. For example, if most players are moving north, these players will be moving south or east and west. These are the players who crack or peel back, “swim upstream” or “go against the grain,” and they are suspect for potentially committing illegal contact fouls.
Through good position and technique, a player initiating an open-handed blindside block can effectively obstruct his opponent with sufficient forceful contact while minimizing the risk of player injury. By teaching these techniques and consistently penalizing infractions, coaches and game officials will have continued taking positive steps toward reinforcing player safety, minimizing injury, and removing unnecessary and excessive contact from the game.

2018-2019 NFHS FOOTBALL GAME OFFICIALS MANUAL POINTS OF EMPHASIS
Equipment Issues to be Addressed
It is critical for all game officials to continue to strengthen their efforts to address all issues that deal with the current equipment requirements. Game officials must focus on these three areas of concern: (1) required equipment not worn properly (pants that do not cover the knees), (2) required and/or legal equipment missing or not being used correctly (no knee pads, thigh guards or hip pads), and (3) wearing illegal equipment (a hard cast not properly covered).
One adjustment made to Rule 1-5-4 requires that the head coach will verify to the referee and another game official prior to the game that "his players have been issued all of the required equipment and they will not use illegal equipment."
Crew members are encouraged to become very observant throughout their pre-game responsibilities and to be prepared to immediately address any equipment issues with the player and a coach. Appropriate communication with the player in the presence of the coach allows for correction to be made prior to the beginning of the contest and avoids problems during the game.
Once the game has started, a major rule change (NFHS Football Rule 3-5-10e) for 2018 calls for an official's time-out to be declared for the removal from the game for at least one down of any player who is wearing required/legal equipment improperly or not at all or is wearing illegal equipment. It is certainly appropriate to allow the correction of the equipment problem quickly and avoid removing the player if the correction/repair is clearly possible in a timely manner (a tooth and mouth protector is hanging from the face mask or a back pad attached to the shoulder pads is not covered by the jersey). Multiple requests are NOT recommended/encouraged to address an equipment problem that continues to be an issue. NFHS Football Rule 3-5-10e is likely to get results as this concern is addressed.
Rule 9-9 (Failure to Properly Wear Required Equipment) has been deleted from the 2018 NFHS Football Rules Book. Rule 3-6-2 no longer calls for a delay-of-game foul for failure to properly wear required/legal equipment. An important change to Rule 9-8-1h calls for an unsportsmanlike foul charged to the head coach if, and only if, a player(s) is wearing illegal equipment.
Game officials are very strongly urged to immediately address this current problem with equipment issues early and often as the 2018 season begins. There is appropriate rule support now for dealing with these problems, and this problem cannot be ignored. It will not go away if game officials fail to take appropriate action.
Consistent Pace of Play Throughout the Game
The time difference in marking the ball ready-for-play from referee to referee has incorrectly varied and often very significantly. The time period between downs is supposed to be dictated by the offensive team and not the game officials. The rules afford teams the option of running their offense as fast or as slow as they choose. In many situations, teams are waiting for game officials to declare the ball ready-for-play and could have already resumed, or attempted to resume play. Once the ball is retrieved and placed on the ground for play, all game officials should be in position and ready to officiate without worry of an illegal snap. While regularity and consistency is the responsibility of every game official on the field, the referee likely has the most effect on this procedure. Situations occur such as the referee being overly patient for a quarterback receiving the play call from the coach at the sideline or other crew members unevenly hurrying to retrieve the ball as time declines near the end of a half. Such practices, as inadvertent as they may be, project an inappropriate attitude of bias towards one team or the other and additionally subtract from the fairness of the game.
The 2018-2019 NFHS Football Game Officials Manual is clear on the appropriate procedures in the Basic Philosophy Principles section entitled "Marking the Ball Ready for Play." After the ball is spotted, three to five seconds should be the maximum time to signal the ready-for-play, and game officials are required to" hustle to their proper positions" so that the "same tempo can be maintained throughout the game." Teams want and deserve consistency in this regard.
Timing Rules and Procedures
While the rules allow for some flexibility in length of periods and halftime intermissions, there are set limitations. Risk minimization continues to be an emphasis in football and certain rules are in place to protect warm-up and rest periods, and these rules must be followed without exception.
Length of Periods can be shortened:
1. Shorten any period or periods in any emergency by agreement of opposing coaches and the referee. By mutual agreement of the opposing coaches and the referee, any remaining period may be shortened at any time or the game terminated. (3-1-3)
2. By agreement of the opposing coaches and the referee, the halftime intermission may be reduced to a minimum of 10 minutes (not including the mandatory warm-up period). (TABLE 3-1)
3. When weather conditions are construed to be hazardous to life or limb of the participants, the crew of game officials is authorized to delay or suspend the game. (3-1-5)
When dealing with lightning or thunder disturbances during a game, please refer to the "NFHS Guidelines on Handling Practices and Contests During Lightning or Thunder Disturbances" in Appendix E of the NFHS Football Rules Book. If a lightning or thunder disturbance occurs near halftime intermission, this delay cannot be treated as halftime intermission. After a weather delay, by rule the second period must be completed and halftime intermission shall be declared. (3-1-3) Halftime intermission may be reduced to a minimum of 10 minutes by agreement of the opposing coaches and the referee. (3-1-3, TABLE 3-1) Rest periods are important for the well-being of the players and should be followed as prescribed.
