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.
