If a law enforcement officer investigating a violation of RCW 46.61.370 has reasonable cause to believe that a violation has occurred, the officer may request the owner of the motor vehicle to supply information identifying the driver of the vehicle at the time the violation occurred. When requested, the owner of the motor vehicle shall identify the driver to the best of the owner's ability. The owner of the vehicle is not required to supply identification information to the law enforcement officer if the owner believes the information is self-incriminating.
