Maine Truck Idling Law
Maine limits commercial vehicles to 5 minutes in any 60-minute period (38 M.R.S. 585-L), with an extra 10 minutes for heat at 32F or below and no limit at all below 0F. Other exemptions cover maintenance and non-propulsion PTO work. The DEP sets the fine, which the statute does not state, so confirm the amount.
Some figures on this page are flagged medium confidence. The limit and source are solid, but a specific fine or local detail should be confirmed with the state agency before you rely on it.
