State Incentives

Alternative Fuel and Fuel-Efficient Vehicle Tax Credit

The state provides an income tax credit of 35% of the vehicle purchase price, up to $2,500, for an original equipment manufacturer compressed natural gas (CNG) vehicle registered in Utah. It also provides an income tax credit of 50% of the cost to convert a vehicle to run on propane, natural gas, or electricity, up to $2,500. Retrofitted CNG vehicles are also eligible for the credit if they meet the National Fire Protection Association Vehicular Gaseous Fuel Systems Code 52 and satisfy the emissions standards for the county in which the retrofitted vehicle is registered; or for the county in the state with the least stringent emissions standards. Other new clean fuel vehicles that meet air quality and fuel economy standards may be eligible for a credit of $605, including certain electric and hybrid electric vehicles.

These incentives expire December 31, 2014. See the Clean Fuel Vehicle Tax Credit website for eligible vehicles, restrictions, and additional information. (Reference Utah Code 19-1-406, 59-7-605, and 59-10-1009)

Laws and Regulations

State Fleet Idle Reduction Requirement

State of Utah fleet vehicles must turn off their engines when stopped for more than 30 consecutive seconds. Exemptions apply. State agencies must develop a compliance policy for their vehicle fleet.

The Utah Department of Administrative Services (DAS) must implement a six-month pilot project testing the effectiveness of agency anti-idling policies. After the project concludes, DAS must prepare a report detailing the effectiveness of agency idle reduction policies in reducing vehicle idling time and compiling cost savings from the reduction in engine use.

(Reference Executive Order 005, 2012)

School Bus Idle Reduction Regulations

School bus drivers must turn off bus engines as soon as possible at loading and unloading areas and only restart the engine when it is time to depart. Exceptions include extreme weather conditions and idling in traffic. At bus depots, drivers are required to limit engine warm-up to the time recommended by the engine manufacturer. All school bus drivers in the state receive a minimum of 30 minutes of idling reduction instruction during their annual service training. In addition, school districts must revise bus schedules to maximize efficiency and assign the cleanest buses to the longest routes. (Reference Utah Code 41-6a-1308 and Standards for Utah School Buses and Operations)

Local Vehicle Idling Regulations

A local highway authority may not enact an ordinance that prohibits or restricts an owner or operator of a vehicle from idling the vehicle's engine, unless the ordinance is primarily educational, specifies that a person must be issued at least three warnings before a fine is imposed, has the same fine structure as a parking violation, provides for the safety of law enforcement personnel enforcing the ordinance, and specifies that the ordinance may be enforced on public property or private property that is open to the general public. Exceptions apply. (Reference Utah Code 41-6a-208)
