There are several types of penalties in football including dead ball, live ball, and simultaneous with the snap penalties. Penalties result in the loss of yards and sometimes downs. Common 5 and 10 yard penalties include false start, illegal motion, pass interference, and personal fouls. Penalty enforcement depends on whether the foul occurred during a running play, loose ball play, or dead ball. Special rules apply for offsetting penalties, automatic first downs, and reporting penalties to the referee.
