Allows for civilian traffic investigators to be issued or use a vehicle that has emergency equipment and red and amber lights; prohibits such vehicles from using blue lights or bearing symbols or markings that identify the vehicle as a police vehicle. Restricts investigations of civilian traffic investigators to crashes involving property damage subject to State motor vehicle laws.
