Oregon Truck Idling Law
Oregon caps a truck's main engine at 5 minutes of idling in any 60-minute period, with up to 30 minutes for a single load or unload (ORS 825.605, enforced by ODOT). The limit covers commercial vehicles over 10,000 pounds GVWR on public roads and any premises open to the public (truck stops, rest areas, terminals). The sleeper-berth heat or AC break only applies in trucks over 26,000 pounds when it is below 50F or above 75F, and it does not apply if the truck has an APU. A citation can go to the driver, the carrier, or both.
When you can keep idling
- Traffic or mechanical trouble you cannot control
- State or federal inspections
- Repairs, service, or DPF regeneration
- Powering work equipment mounted on the truck (PTO, pumps, lift gates, reefer)
- Sleeper-berth heat or AC in trucks over 26,000 lbs, only when it is below 50F or above 75F, and not near a K-12 school
APUs and idle-reduction gear
Running an APU or reefer is fine. Having an APU (or parking where stationary idle-reduction such as electrified parking is available) cancels the sleeper-berth idling exemption, except a heat-only APU still lets you idle for A/C above 75F. A working APU or idle-reduction system also earns up to a 550-pound weight allowance (ORS 818.030).
City and county ordinances
No notable city or county idling ordinance was found for Oregon in the EPA, DOE, or ATRI references. Watch local noise and parking rules.
