n. a state law which sets standards of care by the driver of a car to a non-paying passenger. Although state laws vary, the basic concept is that the social passenger can bring suit for negligence against the driver only for gross negligence if the driver could have foreseen that his/her actions or car could put the rider in great peril. Examples: driving while drunk, going far over the speed limit, playing "chicken", taking chances, driving a car knowing the brakes are faulty, or particularly continuing the reckless driving after the passenger has asked the driver to stop or asked to be let out.
