Is It Illegal to Vape or Smoke While Driving in Indiana?

If you’re a driver in Indiana who vapes or smokes, you’ve likely wondered about the specific rules of the road. Can you use your vape pen during your commute on I-465? Is it legal to light up a cigarette while driving through the Hoosier State? While Indiana does not have a specific law that explicitly prohibits the act of smoking a cigarette or vaping a nicotine product while driving, this doesn’t mean it’s a legal free-for-all. This guide provides a comprehensive breakdown of Indiana’s laws on vaping and smoking behind the wheel.

The Direct Answer: It Depends on What You’re Vaping or Smoking

Let’s start with the most common question: is it illegal to vape or smoke while driving in Indiana? The answer depends entirely on the substance involved.

Tobacco and Nicotine Products: As of 2025, there is no state statute that specifically makes it illegal for an adult (21+) to smoke a traditional cigarette or vape a nicotine-based product while driving a private vehicle. Indiana’s smoking laws, including the Smoke-Free Air Act, regulate use in public indoor spaces and workplaces but do not extend to private vehicles.
Cannabis (Marijuana): In stark contrast, it is explicitly illegal to consume cannabis in any form, including smoking or vaping, while operating a vehicle. All marijuana products remain illegal for recreational use in Indiana, and doing so while driving can lead to serious OWI (Operating While Intoxicated) charges.

While tobacco/nicotine use isn’t directly banned, it’s not without legal risks. The key legal frameworks that can come into play are distracted driving laws and, in some localities, specific ordinances regarding minors.

When Smoking or Vaping Can Lead to Legal Trouble

Distracted Driving Laws: A Broad Net for Tobacco and Nicotine

Indiana takes distracted driving very seriously. The state’s “hands-free” law, effective since July 1, 2020, makes it illegal to hold or use a mobile electronic device while operating a moving vehicle. While this law primarily targets cell phones, the broader principle of preventing distracted driving can apply to any activity that diverts a driver’s attention from the road. Legal experts and safety advocates explicitly list smoking and vaping as potential distractions that can lead to citations under general distracted or careless driving statutes if they impair a driver’s ability to operate their vehicle safely.

Smoking or vaping can easily fall into the main categories of distraction:

Manual Distraction: Taking one or both hands off the wheel to find a vape device, search for a lighter, light a cigarette, handle an ashtray, or adjust device settings.
Visual Distraction: Taking your eyes off the road to perform any of the above actions, or if your vision is temporarily obscured by a thick cloud of vapor or smoke.
Cognitive Distraction: Your mental focus is on the act of smoking or vaping rather than on the road and surrounding traffic.

If a law enforcement officer observes you driving erratically (e.g., swerving, failing to maintain a consistent speed) and determines that your smoking or vaping is the cause, you could be cited for distracted driving or a related moving violation. Penalties for a first distracted driving conviction in Indiana can include a fine of up to $500 and potential points on your driver’s license.

The Critical Exception: Vaping or Smoking with Minors in the Car

Unlike some states that have enacted specific laws prohibiting this, as of mid-2025, Indiana does not have a statewide law that makes it illegal to smoke tobacco or vape nicotine in a vehicle when minors are present. The CDC confirms that Indiana is among the states with no statewide restrictions on smoking in vehicles with children. Legislative efforts to create such a ban, such as a proposed bill in 2019 (Senate Bill 34), have repeatedly stalled and have not been enacted into law.

However, this is where local ordinances become critically important. Some cities and counties in Indiana have taken matters into their own hands. For example, Monroe County (which includes Bloomington) has a public smoking ordinance that explicitly bans smoking in a vehicle if a child is present. Violating this local ordinance is a Class D infraction, with fines up to $100 for a first offense.

Summary: Vaping and Smoking While Driving in Indiana

Scenario	Is it Legal? (21+)	Governing Law / Considerations	Potential Penalties
Vaping/Smoking Tobacco or Nicotine (Alone or with Adults)	✅ Yes (Statewide)	No explicit statewide ban, but subject to distracted driving laws.	None, unless it leads to a distracted driving citation (fines up to $500, plus points).
Vaping/Smoking Tobacco (with Minor Present)	⚠️ Varies by Location	No statewide law. Some local ordinances (e.g., Monroe County) prohibit it.	No statewide penalty. Local fines (e.g., up to $100 in Monroe Co.) may apply.
Vaping/Smoking Cannabis (Driver or Passenger)	❌ No	Explicitly illegal under OWI/drug laws.	Serious OWI penalties including arrest, license suspension, fines, and potential jail time.

Other Relevant Laws and Considerations

Indiana’s Tobacco 21 Law: Under Indiana law, it is illegal to sell, give, or furnish tobacco or vapor products to anyone under the age of 21. Underage possession or use remains illegal in all settings, including vehicles.
Commercial Drivers: Commercial drivers are subject to stricter federal regulations from the Federal Motor Carrier Safety Administration (FMCSA), which prohibit any activity that could impair safe operation. Many commercial carriers also have strict no-smoking/no-vaping policies.
State-Owned Vehicles: Indiana’s Smoke-Free Air Law does prohibit smoking in vehicles owned, leased, or operated by the state when used for a governmental function.
Insurance and Liability: Even if you avoid a ticket, being engaged in smoking or vaping at the time of an accident could be used by insurance companies or in a civil lawsuit to argue that you were negligent or distracted. This could affect your ability to recover damages and may impact your insurance rates.

Conclusion: Legal Nuance vs. Unwavering Safety

In conclusion, while Indiana law does not explicitly ban the act of an adult vaping a nicotine product or smoking a cigarette while driving a private vehicle, it is far from a risk-free activity. The most responsible and legally sound advice for all drivers in Indiana is to keep your full attention on the road. The state’s hands-free law sends a clear message about the importance of avoiding distractions. As laws and public perceptions continue to evolve, the safest bet is to wait until you have reached your destination or have pulled over to a safe, legal location to smoke or vape. Prioritizing safety not only protects you and others on the road but also ensures you stay on the right side of the law in the Hoosier State.
