1.1The game is divided into 4 periods called quarters.
1.2Not counting time outs, the 1st and 3rd quarters consist of 15 minutes.
1.3After 10 minutes of play in the 2nd and 4th quarters (not counting time outs), the referee informs both teams that 2 minutes remain before the last 5 plays of the quarter. Following the 3 minute warning signal (not counting time outs), the referee informs both teams that only 5 plays remain before the end of the half. These 5 plays do not include converts, kick-offs or downs replayed because of a penalty.
1.4The time clock starts on the referee's whistle at the beginning of play in each quarter. The time clock runs continuously except during time outs and the last 5 plays of a half. Otherwise, the time clock can only be stopped and restarted on the head referee's signal.
1.5During the last 5 plays of the 4th quarter, the head referee can stop the game if he or she feels that the security of the players is compromised.
1.6Each half will begin with a kick off from the kicking team's 45-yard line.
The 1st and 3rd quarters will end when no time remains in the period when the ball becomes dead at the end of a legal play.
1.7At the start of the 2nd and 4th quarters, the teams will change ends. The ball will be put into play by the team entitled to do so, at the appropriate point determined by the end of the last play of the previous quarter.
1.8A half shall end when no time remains in the period when the ball becomes dead at the end of a legal play.
1.9The clock must be stopped if the ball falls off the kicking tee.
1.10When a touch down is scored on the final play of a period, the convert attempt must be completed before that period is considered completed.
2. Overtime
2.1When the score is tied at the end of the game, overtime procedures are as follows:
A 3-minute rest period is allowed at the end of the 4th quarter;
Team captains will assemble for a coin toss (like pre-game); the winner of the coin toss chooses to start on offense or on defense.
Each team has 3 attempts to score a 1 or 2 point convert, at their convenience.
2.2If the score is still tied after the 3 convert attempts have been played on each side, there will be a 1-minute rest period. Each team will then have 1 chance at another convert attempt (in the same order) until 1 team outscores the other.
3. Changing Sides
3.1At the end of the 1st and 3rd quarter, the 2 teams change sides on the field.
3.2The team in possession of the ball will then restart the next play at a point corresponding exactly to the point where the ball became dead at the opposite end of the field, and in exactly the same manner as if play had not been interrupted by the end of the previous period.
4. Half Time
4.1At the end of the 2nd quarter, a 5 minute rest period is allowed. With the approval of the captains on both teams and the head referee, the length of the half time period can be modified.
