A gasoline-fueled motor vehicle is not allowed to operate for more than three consecutive minutes when the vehicle is not in motion, with the following exceptions: 1) a vehicle stopped in a line of traffic; 2) a vehicle being inspected by a state or federal motor vehicle inspector; 3) an emergency vehicle operating in an emergency situation; 4) a vehicle being repaired or serviced; 5) a vehicle whose primary or secondary power source is used for a mechanical operation other than propulsion; and 6) a vehicle parked in a non-residentially zoned area with a sleeper berth being used for sleeping or resting. A gasoline bus loading or unloading passengers may idle for 15 consecutive minutes in a 60-minute period.

A diesel-fueled motor vehicle is not allowed to operate for more than three consecutive minutes when the vehicle is not in motion. If the vehicle is not in a parking space equipped with idle reduction electrification technology, the following exceptions apply: 1) a vehicle stopped in a line of traffic; 2) a vehicle whose primary power source is used for a mechanical operation other than propulsion; 3) a vehicle being inspected by a state or federal motor vehicle inspector; 4) an emergency vehicle operating in an emergency situation; 5) a vehicle being repaired or serviced; 6) a vehicle with a sleeper berth that is equipped with a Model Year 2007 or newer engine and/or a functioning diesel particulate filter; and 7) a vehicle that uses a technology designed to reduce engine idling, such as auxiliary or alternate power units, generator sets, or bunk heaters. Additionally, diesel vehicles may idle for 15 consecutive minutes when the vehicle's engine has been stopped for at least three hours if the temperature is below 25 degrees Fahrenheit, and a diesel bus loading or unloading passengers may idle for 15 consecutive minutes in a 60-minute period. Violators will be issued fines.
