Frequently Asked Questions

How long can a vehicle idle overnight in Eugene?

Under EC 6.750(b), an engine cannot idle for more than 15 consecutive minutes between 10 p.m. and 7 a.m. if the noise is plainly audible inside a nearby dwelling that isn't the source of the sound.

Does the idling limit apply during the day?

No. EC 6.750(b) only restricts idling noise plainly audible in a dwelling between 10 p.m. and 7 a.m. Daytime idling isn't reached by this specific subsection, though it could still be cited under the general noise-disturbance standard in EC 4.080 if it meets that broader test.

Are delivery trucks or emergency vehicles exempt?

Emergency vehicles responding to or from an emergency, as defined in ORS 801.260, are exempt under EC 6.755(1)(c). A delivery business that needs to idle longer overnight can instead apply to the city manager for a variance under EC 6.755(2).

What is 'plainly audible' under this rule?

EC 4.080(1)(b), which EC 6.750 incorporates, defines plainly audible as sound whose content, like musical rhythms, spoken words, or engine noise, a listener can clearly hear from inside the affected dwelling.
