- In addition to a kickoff, the other free kick is a kick after a safety (safety kick). A punt may be used (a punt may not be used on a kickoff).
- On a safety kick, the team scored upon puts ball in play by a punt, dropkick, or placekick without tee. No score can be made on a free kick following a safety, even if a series of penalties places team in position. (A field goal can be scored only on a play from scrimmage or a free kick after a fair catch.)
- A kickoff may not score a field goal.
- A kickoff is illegal unless it travels 10 yards OR is touched by the receiving team. Once the ball is touched by the receiving team or has gone 10 yards, it is a free ball. Receivers may recover and advance. Kicking team may recover but NOT advance UNLESS receiver had possession and lost the ball.
- When a kickoff goes out of bounds between the goal lines without being touched by the receiving team, the ball belongs to the receivers 30 yards from the spot of the kick or at the out-of-bounds spot unless the ball went out-of-bounds the first time an onside kick was attempted. In this case, the kicking team is penalized five yards and the ball must be kicked again.
- When a kickoff goes out of bounds between the goal lines and is touched last by receiving team, it is receiverís ball at out-of-bounds spot.
- If the kicking team either illegally kicks off out of bounds or is guilty of a short free kick on two or more consecutive onside kicks, receivers may take possession of the ball at the dead ball spot, out-of-bounds spot, or spot of illegal touch.
