Bill > SB159

This bill modifies existing regulations regarding the specific placement of blue and red emergency lights on marked police vehicles. The legislation requires that when a police vehicle has an exterior light bar, the blue light must be positioned on the roof's passenger side, while the red light must be positioned on the roof's driver side. Similarly, for interior lights, blue lights must be displayed on the passenger side's interior, and red lights must be displayed on the driver side's interior. Additionally, the bill allows police vehicles to use a combination of blue and red lights mounted on the front, sides, or rear of the vehicle, but only if the vehicle already has the required roof or interior lights installed. This change provides more flexibility for law enforcement vehicle lighting configurations while maintaining a standardized approach to emergency light placement that ensures visibility and consistency across police vehicles.
