Stop Short
Stopping a vehicle after a race action (see Race below) requires a move action (stopping after a drive action doesn’t require an action; see Not an Action on page 280). Normally, a vehicle continues to move following a race action. You can attempt a Piloting check (see Pilot a Vehicle on page 146) to reduce the distance your vehicle moves before stopping after a race action by the result of your check, rounded down to the next 5-foot increment. For example, with a result of 17 you would reduce the distance moved by 15 feet (3 squares).
