Is Vaping and Driving Illegal in Arizona? (2025 Guide)

,
Arizona Vaping Driving Law

Arizona, a state known for its vast desert landscapes and iconic highways, has a unique and often misunderstood set of laws when it comes to smoking and vaping while driving. While there is no explicit statewide law banning the act of smoking or vaping in a private vehicle for adults, the state’s broader traffic safety, public health, and distracted driving laws can still lead to significant penalties. This guide provides an in-depth look at Arizona’s laws regarding vaping and driving, unpacking the statutes, enforcement realities, and crucial exceptions you need to know.

Yes, for adults driving alone or with other adults in a private vehicle, there is no specific state law in Arizona that explicitly prohibits the act of smoking a traditional cigarette or vaping a nicotine product while operating the vehicle. The state’s primary tobacco control framework, the Smoke-Free Arizona Act (A.R.S. § 36-601.01), which bans smoking in most enclosed public places and workplaces, specifically exempts private vehicles that are not being used for employment purposes5. However, this general legality is conditional and comes with several important caveats related to distracted driving, the type of vehicle, the substance being consumed, and the presence of minors.

Distracted Driving and Specific Prohibitions in Arizona

While the act of smoking or vaping itself isn’t banned in a personal car, the consequences of that act can lead to legal trouble. Law enforcement in Arizona focuses on observable safety violations and specific situational prohibitions rather than the behavior itself.

Distracted Driving: A Matter of Officer Discretion

Arizona’s 2021 “hands-off” law (A.R.S. 28-914) primarily targets the use of handheld electronic devices like cell phones. While a vape device is not explicitly named in this statute, broader traffic safety laws like A.R.S. 28-693 (Reckless Driving) can be applied if smoking or vaping causes dangerous driving behavior. An officer has the discretion to issue a citation if they determine that your vaping or smoking behavior contributed to unsafe driving. Examples of distraction could include:

  • Taking your hands off the wheel for an extended period to light a cigarette or handle a vape device.
  • Looking away from the road to find, refill, or adjust your device.
  • Exhaling a large vapor or smoke cloud that temporarily obstructs your vision.
  • Reacting to dropped hot ash or a spilled e-liquid container, causing you to swerve or drive erratically.

Data from the Arizona Department of Public Safety has previously identified “smoking or tobacco use” as a significant cause of distracted driving collisions. A reckless driving conviction is a serious offense, potentially leading to up to four months in jail, $750 in fines, a 90-day license suspension, and eight points on your driving record.

Workplace Vehicles: A Clear Prohibition

A critical distinction in Arizona law is between personal and work vehicles. The Smoke-Free Arizona Act’s ban on smoking in “places of employment” extends to vehicles owned by an employer and operated during working hours if the vehicle is occupied by more than one person. Additionally, state administrative rules prohibit vaping in state-owned vehicles.

Vaping and Smoking with Minors Present

As of 2025, Arizona does not have a specific statewide law prohibiting smoking or vaping in private vehicles when minors are present. This stands in contrast to 12 other U.S. states that have enacted such protections.

However, two small Arizona cities have implemented their own local ordinances:

  • Kingman: Prohibits smoking in cars with anyone under 18 present (enacted 2014).
  • Tempe: Prohibits smoking and vaping in any motor vehicle when a person under 18 is present (Ordinance O2015.12, enacted 2015).

In both cities, these are secondary offenses, meaning an officer cannot pull you over solely for this violation but can add the citation during a stop for another traffic offense. Penalties typically start at $50 for a first offense.

Furthermore, Arizona law specifically prohibits vaping in a vehicle at any time when a foster child is present, under Arizona Administrative Code § 21-6-315.

Marijuana-Specific Vaping Restrictions: A Strict Prohibition

While recreational marijuana is legal for adults 21 and over in Arizona, its consumption in public is not. Under Proposition 207 (A.R.S. § 36-2851), it is strictly illegal to smoke or vape marijuana while driving, operating, or riding in the passenger seat of an operating motor vehicle. This is considered public consumption and is a separate infraction from a DUI.

Additionally, driving while impaired by any substance, including marijuana, is illegal and falls under the state’s laws against Driving Under the Influence (DUI) (A.R.S. § 28-1381). Arizona has a zero-tolerance policy for driving with any impairing drug or its metabolite in your system (for non-medical users), meaning you can be charged with a DUI even if you do not appear visibly impaired.

Conclusion:

In summary, while Arizona state law does not explicitly prohibit adults from vaping or smoking nicotine products while driving in their personal vehicles, these activities exist in a legal gray area governed by broader traffic safety statutes and specific situational prohibitions.

The safest and most responsible approach for all Arizona motorists is to avoid smoking or vaping while driving altogether. This not only eliminates any potential legal risks under distracted driving statutes but also helps ensure the safety of yourself, your passengers, and other road users. Given the ongoing evolution of public health perspectives and traffic laws nationwide, it is always wise to prioritize focus and safety behind the wheel.
