Vaping while driving in Arizona is not explicitly prohibited by state law. As of mid-2025, there is no statewide statute that makes it illegal for adults to use e-cigarettes or vape devices while operating a motor vehicle. However, there are important restrictions and safety considerations every driver should know.
State Law: No Blanket Ban, But Key Exceptions
Arizona law does not specifically ban vaping while driving for the general public. That means, in most cases, adults can legally vape and drive. However, the law does prohibit vaping in a vehicle if a foster child is present. This is a targeted restriction designed to protect children in foster care and is enforced under Arizona Administrative Code § 21-6-315.
Additionally, it is illegal to vape in a car with any person under the age of 18 present. This rule is enforced as a secondary offense, meaning law enforcement can only cite you for it if they have stopped you for another reason, such as a traffic violation.
Distracted Driving Laws Still Apply
Although vaping and driving is not directly outlawed, drivers must always maintain full control of their vehicle. If vaping distracts you—by taking your hands off the wheel, obstructing your vision with vapor clouds, or otherwise impairing your driving—you could be cited under Arizona’s distracted driving laws. Distracted driving is a primary offense and can result in fines or more serious penalties if it leads to an accident.
Local Ordinances and Restrictions
Some Arizona cities and counties have adopted stricter local rules regarding vaping in public and in vehicles. For example, cities like Phoenix, Tempe, and Mesa have enacted ordinances that may restrict vaping in certain public areas, workplaces, or city vehicles.
Always check for local signage and be aware of specific city or county ordinances, as these can be more restrictive than statewide laws.
Age Restrictions and Product Legality
The minimum legal age to purchase and use vaping products in Arizona is 21, aligning with federal law. Selling or furnishing vape products to anyone under 21 is a petty offense, and underage possession or use can result in fines or community service.
