An authorized emergency vehicle, other than police vehicles, must be equipped with __________.

An authorized emergency vehicle is typically required to be equipped with red lights to ensure it is easily identifiable and distinguishable from other vehicles when responding to emergencies. The use of red lights signals urgency and alerts other road users that the vehicle is on an emergency mission, thereby allowing it the right of way when necessary. This requirement helps enhance the safety of both the emergency responders and the public while ensuring that other drivers can recognize and react appropriately to the presence of the emergency vehicle.

In many jurisdictions, blue lights are more commonly associated with law enforcement vehicles, while green lights may be used by volunteer firefighters or certain types of non-emergency service vehicles. White lights can serve various purposes, including illumination, but do not convey the same urgency as red lights and are not standard for authorized emergency vehicles in emergency situations. Thus, the specification of red lights aligns with established traffic regulations that prioritize visibility and recognition of emergency vehicles.
