Logan, UT Environmental Rules: Vehicle Idling Restrictions (2026)

Section 10.52.270 (Excessive Noise And Pollution) has two parts. Subsection A is a noise limit: a person operating or controlling a stopped, standing or parked motor vehicle must keep the motor and muffler noise less than eighty five (85) decibels measured at fifty feet (50') from the vehicle. Subsection B is the idling limit. No person operating or having control of a vehicle shall permit the engine to operate for more than two (2) minutes while the vehicle is stationary, except when the local temperature as reported by the United States weather bureau is below zero degrees Fahrenheit (0°F).

Three users are exempt as printed. The section does not apply to idling by on duty police officers or firefighters as necessary for the performance of their official duties, and it does not apply to vehicles owned by the city of Logan as necessary to operate equipment in the performance of official duties.

Subsection C explains the enforcement posture. The city states that its purpose is to comply with the requirements imposed by the state legislature in Utah code 41-6a-208, and the intent is primarily educational. A person must be issued at least one (1) warning citation before a fine may be imposed. The fine is a civil penalty of forty dollars ($40.00), imposed as set forth in § 10.52.290. Officers who enforce the section must follow all Logan City police policies regarding safety.

Location matters. The section can only be enforced on public property or on private property that is open to the general public. A private business with a drive-through is covered only if the owner posts a sign provided by or acceptable to the local highway authority informing customers of the authority's time limit for idling, or adopts an idle reduction education policy approved by the local highway authority. The section was adopted as Ord. 14-16 in 2014 and amended by Ord. 23-12 on 4-18-2023.
