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 van 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 Aerial firefighting 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.
