With vaping’s popularity on the rise, many Missouri drivers wonder: Is it legal to vape behind the wheel? The answer is nuanced, involving both state laws and broader distracted driving regulations. Here’s a detailed look at what Missouri law says about vaping and driving in 2025.
No Statewide Ban on Vaping While Driving
As of 2025, there is no explicit statewide law in Missouri that prohibits vaping while driving. Nicotine vaporizers and e-cigarettes are legal for adults, and using them in your vehicle is not directly addressed by Missouri statutes. This means you won’t be pulled over solely for vaping while driving.
Distracted Driving Laws: The Key Factor
While vaping itself isn’t specifically illegal, Missouri’s distracted driving laws can still apply. The state passed the Siddens-Bening Hands-Free Law, which, effective January 1, 2025, bans all drivers from holding or using handheld electronic devices while operating a vehicle on public roads. However, this law is focused on cell phones and electronic communication devices—not vaping devices.
That said, any activity that distracts you from driving—including vaping—could result in a citation if it leads to unsafe driving. If a police officer observes that vaping is causing you to swerve, lose focus, or otherwise drive dangerously, you could be cited for distracted or careless driving.
Local Ordinances and Restrictions
Missouri does not have a statewide vaping ban, but local governments may enact their own restrictions. Some municipalities could prohibit vaping in certain public areas or while operating a vehicle, especially in places where smoking is already banned. Always check local ordinances if you’re unsure.
Special Considerations
Minors and Vaping: It is illegal for anyone under 21 to purchase or possess vaping products in Missouri, following federal law.
Driving with Minors: While Missouri does not specifically ban vaping in cars with children present, some states do have such laws. Using e-cigarettes around minors is discouraged due to health risks.
Impaired Driving: If you vape substances containing THC or other impairing drugs, you could be charged with driving under the influence (DUI), which is a serious offense.
Safety and Liability
Even though vaping while driving is not specifically outlawed, it can be dangerous. Vaping may cause:
Visual distraction (clouds of vapor obstructing view)
Manual distraction (handling the device)
Cognitive distraction (taking your mind off the road)
If vaping leads to an accident, you could be held liable for distracted driving, regardless of the device used.
What Missouri Drivers Should Do
Avoid vaping while driving to minimize distraction.
Pull over safely if you need to vape.
Be aware of local laws that may impose stricter rules.
Never vape substances that impair your ability to drive.
Quick Reference Table
| Activity | Legal in Missouri? | Notes |
|---|---|---|
| Vaping nicotine while driving | Yes | No explicit ban, but avoid distraction |
| Vaping THC while driving | No | DUI laws apply |
| Vaping with minors in car | Not banned | Strongly discouraged; some local rules may apply |
| Vaping as a distraction | No | Can result in citation if it causes unsafe driving |
Vaping while driving is not specifically illegal in Missouri, but distracted driving laws mean you could still face penalties if vaping interferes with your ability to drive safely. Always prioritize safety, stay informed about local regulations, and avoid any behavior that could put you or others at risk on the road
