Courtesy lights

Courtesy lights are used to request right-of-way primarily by volunteer or on-call firefighters, emergency medical technicians (EMTs), and other first responders to expedite their response in their privately owned vehicles to their firehouse, base, or directly to the scene of an emergency call.

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."

In Virginia, any member of a fire department, volunteer fire company, or volunteer emergency medical services agency and any police chaplain may equip one of their owned vehicles 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] In the United Kingdom, courtesy lights may only be used by doctors (registered and qualified) on vehicles, when responding to an emergency.

[9][10] In Canada, firefighters in Ontario, Alberta, and Quebec may use green flashing lights in their personal vehicles.

Like Saskatchewan and Manitoba, Nunavut volunteers can break the law when responding to the station, or to emergencies, as well as legally compelling traffic and other motorists to get out of their way.
