Wyoming Truck Idling Law
Wyoming has no statewide idling time limit. The only related law is a decades-old unattended-vehicle rule about shutting off and taking the key when you leave the truck, and it is essentially never enforced against a resting driver.
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.
