The Holladay City Council has approved an ordinance limiting vehicles from idling more than two minutes in most circumstances.
The new regulation, passed unanimously on Thursday, is meant to be primarily educational. The goal is to protect the public health and improve the environment by reducing emissions while conserving fuel.
Businesses with drive-through service are exempted if they post a sign informing customers of Holladay's limit.
Idling more than two minutes also is permitted in some cases, including if the vehicle is stopped at a traffic signal or at the direction of a police officer; if the temperature is below 32 degrees or above 90 degrees; if needed for emergency vehicles to operate equipment; for testing purposes; and to recharge a battery in a hybrid electric vehicle.
In addition, a vehicle can idle to operate equipment such as a transportation refrigeration unit, crane, pump drill or hoist. On-duty police officers also can idle their cars if it's necessary to perform their duties.
The ordinance is enforceable on all public property and on private property that is open to the general public.
Drivers get warnings for the first three offenses. The fourth offense within 12 months brings a $160 fine and subsequent violations within 24 months of the first offense is a $210 fine. The fines will be reduced by $110 if paid within 10 days; by $70 if paid within 20 days; and by $40 if paid within 30 days.
The vehicle's owner is liable for the fine.
Salt Lake City approved a similar ordinance in 2011.
