Vaping while driving in Indiana is not explicitly illegal under state law for adults, but it can still lead to fines or charges if it distracts you or involves cannabis or minors. The key distinction is between nicotine vaping and marijuana use, plus how the act affects your driving.
Vaping nicotine while driving
Indiana does not have a statute that outright bans an adult (21+) from vaping or smoking nicotine while driving a private vehicle. However, if vaping causes you to drive erratically, drift lanes, or fail to obey traffic rules, police can cite you under Indiana’s distracted or careless‑driving laws. First‑offense distracted‑driving penalties can include fines up to around $500 and points on your license.
Driving with minors in the car
Currently, Indiana has no statewide law banning vaping or smoking in a vehicle when minors are present. But some local governments have their own rules; for example, Monroe County prohibits smoking in a vehicle if a child is present, and violating that local ordinance can bring a small fine. Always check local city or county ordinances if you regularly drive with kids.
Vaping marijuana or while impaired
It is explicitly illegal to consume cannabis in any form, including vaping marijuana, while operating a vehicle in Indiana. Marijuana remains illegal for recreational use, and using it while driving can lead to OWI (Operating While Intoxicated) charges, with serious penalties such as arrest, license suspension, fines, and even jail time.
Age, possession, and other rules
Indiana’s Tobacco 21 law makes it illegal to sell or give tobacco or vaping products to anyone under 21, and underage possession or use is illegal in all settings, including cars. Commercial drivers are also subject to stricter federal rules that discourage any activity that could impair safe operation.
