If a character driving or piloting a vehicle is Shaken, he must make an Out of Control roll (see page 115). If the vehicle suffers damage, calculate it at half the vehicle's Top Speed (see page 113).

Characters who are Shaken at the start of a turn make their maneuvering Trait roll at -2. They attempt to become un-Shaken on their Action Card as usual.
