As of 2025, there is no specific Montana state law that prohibits vaping while driving. Adults aged 21 and over are legally allowed to use e-cigarettes or other vaping devices while operating a motor vehicle. Unlike some states that regulate or ban vaping inside vehicles, Montana has yet to enact legislation directly addressing vaping during driving, making it legal from a statutory perspective.
General Vaping Regulations in Montana
While vaping while driving is not illegal, Montana enforces broader vaping and tobacco regulations:
Age Restrictions:Â Montana follows federal law, prohibiting the sale and possession of vaping products to anyone under 21 years old.
Indoor Vaping Ban:Â Since 2025, vaping is banned indoors in all public spaces and workplaces as part of the Montana Clean Indoor Air Act extension.
School Property:Â Vaping is strictly prohibited on all public school grounds.
These regulations do not extend directly to the use of vape products inside private vehicles except where general distracted driving or child endangerment laws might apply.
Distracted Driving and Safety Considerations
Although vaping while driving is not illegal, it can still fall under distracted or careless driving laws if it impairs safe vehicle operation. For example:
Handling a vape device or refilling e-liquids may distract the driver.
Thick vapor clouds could momentarily obscure visibility.
Taking one hand off the wheel or diverting attention could contribute to unsafe driving behavior.
Montana law enforcement officers have the discretion to issue citations for reckless or careless driving if vaping leads to unsafe actions or traffic violations behind the wheel.
Local Ordinances and Potential Variations
Some Montana cities and counties have adopted local distracted driving ordinances mainly targeting cellphone use, texting, and handheld mobile devices. While these often do not explicitly mention vaping, it’s possible that some local rules could be interpreted to include vaping activities if deemed distracting.
Drivers in Montana should stay aware of local municipal laws or rules in the areas where they drive to avoid unexpected fines or penalties.
Health and Public Safety Perspectives
Public health experts caution against vaping while driving due to safety risks. The use of vape products can impair concentration and motor skills, increasing the potential for accidents. Additionally, vaping in cars with children raises health concerns, although Montana does not currently have a specific law banning vaping in vehicles with minors.
vaping while driving is legal in Montana in 2025, as no state law expressly forbids it for adults. However, legal consequences can arise if vaping results in distracted or reckless driving. Vaping is banned in all indoor public spaces statewide, but private vehicle use remains unregulated beyond general safety laws.
Drivers are encouraged to prioritize safety, minimize distractions, and be mindful of local ordinances that might impose stricter rules. Responsible vaping practices behind the wheel protect everyone on Montana’s roads.
