Wyoming Truck Lane Restrictions
Wyoming has no truck-specific left-lane law. The general keep-right covers every vehicle (Wyo. Stat. 31-5-201). Slower traffic keeps right, and you don't camp in the left lane. It's a misdemeanor traffic violation. The statutory ceiling is high, but the fine you'd actually pay for keep-right runs low.
Some figures on this page are flagged medium confidence. The general rule is solid, but a specific corridor or fine should be confirmed with the state DOT before you rely on it.
