Check: Routine tasks, such as ordinary driving, don’t require a skill check. Make a check only when some unusual circumstance exists (such as inclement weather or an icy surface), or when the character is driving during a dramatic situation (the character is being chased or attacked, for example, or is trying to reach a destination in a limited amount of time). When driving, the character can attempt simple maneuvers or stunts. See Driving a Vehicle for more details.
Try Again?: Most driving checks have consequences for failure that make trying again impossible.
There is no penalty for operating a general-purpose motor vehicle. Other types of motor vehicles (heavy wheeled, powerboat, sailboat, ship, and tracked) require the corresponding Surface Vehicle Operation feat, or the character takes a –4 penalty on Drive checks.
