In Wyoming, as of 2025, it is not explicitly illegal to vape while driving. The state does not have a specific law banning the act of smoking or vaping nicotine products in a private vehicle. Adults driving alone or with other adults may legally vape or smoke while operating a vehicle. However, Wyoming law does include broader traffic safety provisions that could apply if vaping or smoking creates a distraction that impairs safe driving. For instance, under Wyoming Statute 31-5-236 (Careless Driving), a driver could be cited if their actions, such as handling a vape device, cause unsafe driving conditions.
Wyoming also enforces strict littering laws with fines up to $550 for tossing burning substances, like cigarette butts, from vehicles. This is an important consideration when vaping or smoking while driving.
Regarding vaping or smoking marijuana, it is strictly illegal while driving in Wyoming due to the state’s zero-tolerance policy for driving under the influence of intoxicants.
Additionally, Wyoming does not have specific laws prohibiting vaping in vehicles when minors are present, unlike some other states. However, possession or use of vaping products by minors under 21 is illegal and subject to Minor in Possession charges.
Vaping while driving in Wyoming is legal for adults but comes with risks related to distracted driving enforcement and littering laws. Marijuana vaping while driving is strictly prohibited. Drivers should be cautious to avoid impairing their safe operation of the vehicle and to comply with littering laws to prevent penalties.
