utahThe Utah State Legislature has implemented various lighting requirements and restrictions for emergency and maintenance vehicles. All vehicle illumination and safety equipment is subject to approval under emergency vehicle light laws enforced through Title 41, Chapter 6a and Utah Department of Motor Vehicles. The vehicles of topic include the following:

  • fire trucks
  • volunteer firefighter vehicles
  • police vehicles
  • tow trucks
  • ambulances
  • utility vehicles
  • pilot vehicles
  • construction vehicles
  • security vehicles

Police Vehicles

One should know that law enforcement vehicles must adhere to specific rules similar to others, although some general rules do not apply. A general law, stated under section 1616 is that a vehicle lights displaying a red light must not be visible from the front center of the vehicle. However authorized vehicles, including police vehicles, are exempt. Additionally, police cars reserve the right to have blue flashing police lights and rotating lights.

Police cars are also exempt from section 1610, which state that limit the number of spot lights allowed and the law that high intensity spot lights should refrain from shining on mirrors, windows and windshields of other vehicles.

Additional laws exist in which police vehicles are not except. For example, if the vehicle should emit light with a candlepower over 300 intensity, it should not illuminate past 75 feet from the vehicle. Also, if the intensity is 300 or higher, there should not be more than four lights.

Fire Trucks

Fire trucks are listed as authorized vehicles along with police cars and are subject to similar codes and restrictions as police cars. As stated under section 1616, lights with 300 plus candlepower intensity should not shine beyond 75 feet. Furthermore, the fire truck would have to display less than four lights when they are 300 or more candlepower.
Fire trucks, like police vehicles, are exempt from the law prohibits vehicles from displaying a red light front and center.

Both fire trucks and police vehicles are exempt from laws that restrict the number of and illumination of spot lights, as stated in section 1610.

However, they are not exempt from the law that prohibits the visibility of blue lights from the immediate front and center of the vehicle, and as such need to pay attention to the color of fire truck lights that are being used.

Volunteer Firefighter Vehicles

This type of motor vehicle can qualify as an authorized emergency vehicle under the subcategory of "private." These vehicles must meet a number of requirements related to the authorized emergency vehicle standards. They are as follows:

  • The private vehicle is licensed with a certificate of safety inspection.
  • The vehicle is used part-time to help a government agency respond to emergencies.
  • The fire chief has provided written authorization for the vehicle to assist in emergencies.
  • It abides by all laws stated in title 41, section 6a (section 1601-1644).

As a note, volunteer fire fighter lights would then be subject to the same laws as fire truck lights. These laws are listed above in the previous section.

Public and Privately Owned Ambulances

All variations of ambulance vehicles, whether private or public, must be licensed through Title 26, chapter 8a by the Utah Department of Health Bureau of Emergency Medical Services. The license permits an ambulance to response to both emergency and non-emergency situations. There are additional requirements that are as follows:

  • The vehicle has proof of proper insurance.
  • It has a certificate of safety inspection.
  • The owner can provide written permission from both the chief of police where the company resides and the county sheriff.
  • The vehicle complies with siren and emergency light guidelines under Title 41, section 6a.

Such laws under Title 1, 6a are those mentioned above. Note that the same exemptions as police and fire vehicles receive apply if all qualifications have been met to be considered an authorized emergency vehicle. These types of vehicles, as with fire trucks, are not permitted to have the same exemptions as police vehicles, such as laws that pertain to blue lights.

Construction Vehicles

The Utah State legislature has not yet implemented specific lighting rules designated solely for construction and maintenance vehicles, as stated in section 1617 of Title 41, chapter 6a. The laws will be adopted in accord with Title 63G of the "Utah Administrative Rulemaking Act," and they are predicted to align with the "Manual on Uniform Traffic Control Devices for Streets and Highways."

Tow Trucks

utah-state-flagThese vehicles are not considered authorized vehicles and are thus subject to other rules and regulations. First, tow trucks, which are considered those that have a "load extending beyond rear," under section 1606, must contain reflectors, flags or display lights at the rear if the load stretch is 4 feet or more beyond the rear of the vehicle.

During daylight, 12 inch square flags are necessary to indicate its extremities in the case that the load goes beyond the sides or 4 feet beyond the rear. The flags must be positioned in the same place where a reflector or lights would otherwise be.

In the absence of light, the vehicles must also contain a red lights on each side, one with "maximum overhang" and two red reflectors that show maximum length.

Pilot Vehicles

Pilot vehicles are required by the American Association of Motor Vehicle Administrators in Utah to have one of two types of lighting. The first is an AAMVA approved flashing, rotating or oscillating bar on the top of the vehicle that must remain illuminated during the time the vehicle operates. The bar should have a 360-degree view and not be blocked under any conditions.

They may also utilize AAMVA approved, six-inch diameter minimum, flashing amber lights capable of 60 flashes per minute. These must be located on each side of the "oversize load" sign.

Utility Vehicles

Power trucks, also known as utility vehicles are subject to laws stated under Title 41, Chapter 6a, section 16. These vehicles are not permitted to have blue rotating or flashing lights or any red lights that may be clearly seen from the center, front portion of the vehicle. In addition, spot lights are prohibited.

Like most vehicles are subject to, any lights with 300 or more candlepower should not be visible beyond 75 feet of the vehicle and not more than 4 lights over 300 candlepower.

Security Vehicles

Security vehicles, often seen policing malls or other businesses, are subject to laws stated under R156-63a-610. To begin, these vehicles, though often resembling police cars, are not entitled to use blue lights of any kind. Acceptable light colors are white, amber and green, and these colors are permitted for both front and rear facing display.

They are also required to meet all guidelines under 41, 6a, 1616 in the event that they travel on a public highway or road. Requirements stated under 1616 are listed in numerous sections above. Typically, the lights can only operate on company grounds unless otherwise permitted.
