What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

Current law provides that a police vehicle may be equipped with flashing, oscillating, or rotating blue and red lights. On a marked police vehicle, the blue light must be mounted on the passenger side of the vehicle and the red light must be mounted on the driver side of the vehicle.

This bill provides that, on a marked police vehicle with an exterior light bar, the blue light must be mounted on the roof of the passenger side of the vehicle and the red light must be mounted on the roof of the driver side of the vehicle. For lights mounted inside the vehicle, blue lights must be displayed on the interior of the passenger side of the vehicle and red lights must be displayed on the interior of the driver side of the vehicle. The bill also authorizes the use of a combination of blue and red lights mounted on the front, sides, or rear of a police vehicle if the vehicle is already equipped with roof or interior lights as required by the bill.
