Courtesy lights

From Wikipedia, the free encyclopedia

Courtesy lights are used to request right-of-way primarily by volunteer or on-call firefighters and emergency medical technicians (EMTs) to expedite their drive in their privately owned vehicles, to their firehouse or base. Courtesy lights sometimes allow the user to disobey traffic laws such as speed limits, but usually not laws applying to stop signs or stop lights. Courtesy lights should not be confused with emergency warning lights used in conjunction with audible warning systems (sirens) for emergency vehicles such as police cars, fire apparatus, and ambulances, nor should they be confused with warning lights as used by tow trucks, snow plows, construction vehicles and school buses to increase awareness especially when moving slowly or stopped in the roadway.[1]

The term is also used to refer to the internal car light that comes on automatically when a door is opened.

Blue courtesy lights, used by volunteer firefighters


A vehicle lawfully displaying courtesy lights is not an emergency response vehicle. In most states, vehicles displaying courtesy lights must still stop at stop signs, red lights, etc. and may not speed or disobey any traffic regulations.[1] Usually, violation ticket fines are increased if the ticketed car was flashing courtesy lights. Laws vary greatly by state.[2]

In most states, other vehicles are not required to yield to the vehicle displaying the courtesy lights, hence the name "courtesy", although laws requiring permits for those using courtesy lights vary by state.

In the state of New Jersey, for instance, users of a volunteer blue light must abide by all traffic laws including speed limit, stop signs, and red lights; however other non emergency drivers must pull over for a volunteer blue light. State of New Jersey 211th Legislature:[3] "Nothing contained herein is intended to grant to any member of a volunteer fire company or a volunteer first aid or rescue squad any privileges or exemptions denied to the drivers of other vehicles, and such members displaying emergency warning lights and electronic horns shall drive with due regard for the safety of all persons and shall obey all the traffic laws of this State including R.S.39:4-81, provided, however, that the drivers of non-emergency vehicles upon any highway shall yield the right of way to the vehicle of any member of a volunteer fire company or a volunteer first aid or rescue squad displaying emergency warning lights or an electronic horn in the same manner as is provided for authorized emergency vehicles pursuant to R.S.39:4-92."

Police cars, fire trucks, ambulances or other emergency vehicles have sirens and red lights. On the other hand, private vehicles operated by volunteer fire and rescue squad members (with emergency vehicle identification) responding to an emergency call use blue lights.[4] If an officer pulls a vehicle over for using courtesy lights, the driver will need to provide sufficient identification proving their Emergency Personnel status—badge, ID number, ID card—and their reasoning for usage of courtesy lights.

Ohio is one if the few states that allows the use of sirens in conjunction with lights. Volunteer Firemen and EMTs in the state of Ohio may display red flashing lights and use traditional warning sirens in the same way that a traditional fire apparatus would so long as they pass an inspection by the Ohio State Highway Patrol.

In Virginia any member of a fire department, volunteer fire company, or volunteer emergency medical services agency and any police chaplain may equip one vehicle owned by him with no more than two flashing or steady-burning red or red and white combination warning light units of types approved by the Superintendent of the State Police.[5]


Traditionally, blue lights are used for both firefighters and EMTs. However, some states (especially in the Northwestern US) use green lights for both firefighters and EMTs. Other States (most notably New York) use Blue for firefighter and Green for EMTs. White has traditionally been allowed with Blue or Green; however, in recent years, certain states (Pennsylvania, New York) have become more restrictive. Rarely, red is used for courtesy lights. In Pennsylvania, red lights are commonly used to warn of a chief, assistant or anyone holding a position in a fire department. Blue lights are for the other volunteers.
