As of May 2025, there is no Missouri state law that specifically prohibits vaping while driving. Drivers are not explicitly barred from using e-cigarettes or vape devices behind the wheel, and vaping is not included in the state’s distracted driving statutes. This means that, in general, it is legal to vape while operating a vehicle in Missouri.
Distracted Driving Laws: Indirect Implications
While vaping itself is not illegal, Missouri’s distracted driving laws are relevant. The Siddens Bening Hands-Free Law, effective January 1, 2025, prohibits all drivers from using handheld electronic devices for activities such as texting, making calls, or using apps while driving.
However, this law does not include vaping devices, as they are not classified as electronic communication devices under the statute.
That said, if vaping distracts you-such as taking your hands off the wheel, obstructing your view with vapor, or otherwise failing to pay attention to the road-you could still be cited for careless or distracted driving if your behavior endangers yourself or others. If vaping leads to an accident, you may be found at fault and subject to civil or criminal penalties.
Local Ordinances and Federal Restrictions
Some localities or private properties (such as schools or hospitals) may have their own rules prohibiting vaping on their premises, but these do not generally extend to driving on public roads. There are also federal age restrictions: it is illegal for anyone under 21 to purchase or possess vaping products.
Key Takeaways
- Vaping while driving is not specifically illegal in Missouri.
- Distracted driving laws can still apply if vaping causes you to lose focus or control of your vehicle.
- New hands-free laws do not mention vaping devices; they target phones and similar electronics.
- Causing an accident while vaping can result in liability and penalties, even if vaping itself is not banned.
- Always check for local ordinances or property-specific rules that may restrict vaping.
You can legally vape and drive in Missouri, but if vaping distracts you or contributes to an accident, you can still face legal consequences. Safe and attentive driving should always be your priority.
