No, it is not illegal to vape while driving in Wyoming—there is no specific state statute banning the act for adults using nicotine products in private vehicles. However, related laws on distracted driving, littering, and intoxicants can lead to citations if your actions create safety risks.
Core Vaping Rules on Wyoming Roads
Wyoming prioritizes personal liberty, so vaping nicotine or tobacco products while driving alone or with consenting adults carries no direct prohibition. This differs from states like Utah with stricter distracted driving definitions.
Enforcement hinges on observable impairment under Wyoming Statute § 31-5-236 (careless driving), which penalizes any conduct creating “unreasonable risk of harm”—such as fumbling a vape device, obscuring vision with clouds, or dropping e-liquid.
Minors under 18 don’t trigger a smoking ban in vehicles (unlike 29 other states), but those under 21 face Minor in Possession charges (§ 14-3-310) for any vaping, with $25 fines or community service.
Key Risks and Penalties
Littering poses the clearest trap: Tossing vape pods or cigarette-like disposables qualifies as “tossing a burning substance,” drawing fines up to $550. Courts upheld this in Mahaffy v. State (2023), validating stops for such acts.
Marijuana vaping is strictly illegal under Driving While Under the Influence of Intoxicants (DWUI) laws—zero tolerance for any detectable THC, even without visible impairment.

Enforcement and Best Practices
Officers use discretion, often during traffic stops. No 2026 changes (e.g., HB0132 targets manufacturing licenses, not driving) alter this. Wyoming Highway Patrol emphasizes safety over behavior policing.
Pull over to vape, secure devices in holders, and avoid clouds near windows. Check local codes in Cheyenne or Casper, as municipalities may add rules. For updates, consult Wyoming DOT or statutes directly.
