Under current law, firetrucks must be identified by red lights of an intermittent flashing type, visible from both front and rear for a distance of 500 feet under normal atmospheric conditions. The red flashing lights must be in operation at all times when the vehicle is on emergency status.
An emergency or work zone is defined as the adjacent lanes of the roadway 200 feet before and after:
Drivers approaching an emergency or work zone must proceed with caution and, if the opportunity exists, with due regard for safety and traffic conditions, yield the right-of-way by making a lane change or moving away from the lane or shoulder occupied by an emergency or work zone vehicle. If approaching the emergency or work zone on a highway having less then four lanes, the driver must also reduce the speed of the vehicle. If changing lanes or moving away would be unsafe, the driver must proceed with due caution and reduce the speed of the vehicle to at least 10 miles per hour below the posted speed limit.
Firetrucks may operate rear-facing blue lights. The combination of red and blue lights may only be used at the scene of an emergency.
Drivers must reduce their speed to 50 miles per hour or less, on a highway with a speed limit of 60 miles per hour or more, if unable to move over when approaching an emergency or work zone.
