emergency vehicles

An emergency vehicle is a vehicle used by emergency services. Emergency vehicles typically have specialized emergency lighting and vehicle equipment that allow emergency services to reach calls for service in a timely manner, transport equipment and resources, or perform their tasks efficiently. Emergency vehicles are usually operated by authorized government agencies, but some may also be operated by private entities where permitted by law.

Emergency vehicles are usually given right of way in traffic, and may be exempted from certain basic road laws to reach their destinations in the fastest possible time, such as driving through a red traffic light or exceeding the speed limit; however, this is almost always done with emergency lights and sirens on, to alert traffic that the emergency vehicle is approaching. In some jurisdictions, the driver of an emergency vehicle can face legal action if the driver shows "reckless disregard for the safety of others".

Types

There are many types of emergency vehicles. Which service operates which vehicle depends on the jurisdiction. Examples of emergency vehicles include:

* Police
** Police car

** Police motorcycle
** Police bicycle
** SWAT vehicle
** Mobile communications vehicle
** Police bus
** Police aviation
** Police watercraft

* Fire
** Fire engine
** Fire command vehicle
** Fire bike
** Light and air unit
** Water tender
** Fireboat

* Emergency medical services
** Ambulance
** Ambulance bus
** Nontransporting EMS vehicle
** Motorcycle ambulance
** Air medical services
** Water ambulance
* Other
** Rescue vehicle
** Hazardous materials apparatus
** Tow truck

Equipment

Many emergency response vehicles (especially those of the main police, fire and ambulance services) are likely to be fitted with audible and visual warning devices, which are designed to facilitate their movement through traffic to reach their destination, and to provide some protection on the scene.

Depending on local laws, vehicles on the road may be required to yield the right of way to emergency responders who are using their warning devices. For example, in Utah, when an emergency vehicle is on the road while using its warning devices, all cars are required to pull over to the side of the road, stop, and wait for the vehicle to pass before resuming normal driving, unless doing so would cause an accident or if stopped at a red light or stop sign. Even in areas where no such laws exist, many motorists may allow the vehicle to pass as a matter of courtesy.

Livery

Liveries are graphic designs on emergency vehicles that are intended to identify the vehicle's respective emergency service, improve visual identification, and differentiate emergency vehicles from regular traffic. Each service's design choices reflect different needs, but typically include:
* Identification of the service – Text or logos identifying the emergency service to which the vehicle belongs, and its purpose to the public and other services. Occasionally, the name of the service ("police", "ambulance", etc.) may be written in reverse lettering on the front of the vehicle; this lettering is reflected properly in rear-view mirrors.
* Vehicle ID number – A fleet number or unit number, typically printed on the roof, trunk, or fender of the emergency vehicle, allowing for easy internal identification and fleet maintenance.
* High visibility markings – A design or paint scheme that makes the emergency vehicle distinct or highly visible, and thus easily identifiable as an emergency vehicle from a distance. These can be as simple as unique paint schemes (such as black and white for police, or bright red for fire) or stripes, or as complex as Battenburg markings or intricate images evoking the jurisdiction they serve. Police are typically exempted from this, and they may be able to use unmarked police cars that lack any markings whatsoever, thus resembling civilian traffic.
* Contact information – Appropriate contact information for the emergency service operating the emergency vehicle, or appropriate methods to request their assistance. The most common contact information printed on an emergency vehicle is an emergency telephone number, usually a national uniform number, but also a service's respective dedicated emergency number if they have one. The service's phone number or website link may also be used, though these are often less emphasized so as to not confuse
