Alaska Truck Idling Law
Alaska has no statewide idling time limit, which fits its cold-weather driving, and no Alaska city is confirmed to set a general idling limit (the "Anchorage/Juneau 5 minutes" figure that circulates online is not in any municipal code). The one idling-related provision is a 550-pound weight allowance for APUs / idle-reduction technology (17 AAC 25.013(g)). Anchorage does require you to shut off the engine when leaving the truck unattended on a public street.
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.

City and county ordinances
