Vaping while driving in Washington state is NOT specifically illegal for adults, but it can get you cited for distracted driving or other violations if it affects your ability to safely operate a vehicle. There are also important restrictions to be aware of depending on age, location, and the substance being vaped.
What the Law Says
1. No Direct Ban for Adults in Private Cars
For adults 21 and older, there is no law that directly prohibits vaping (nicotine) while driving a privately owned vehicle in Washington state.
However, the Washington “Dangerously Distracted Driving” law (RCW 46.61.673) makes it illegal to participate in any activity while driving that interferes with safe vehicle operation. Vaping (like eating, smoking, or adjusting controls) can be included if it distracts you.
2. Penalties for Distracted Driving
Police cannot pull you over solely for vaping, but if you’re stopped for another violation and vaping is deemed a distraction, you may be cited for “dangerously distracted driving.”
The fine is $99 and may impact your driving record and insurance.
Repeat or more serious violations (if reckless or causing an accident) can result in heavier charges.
3. Strict Prohibitions for Cannabis
It is strictly illegal to vape or smoke cannabis while driving or as a vehicle passenger—no exceptions—even though marijuana is legal for adults in Washington. Doing so carries severe penalties as it is treated as a DUI.
Legal THC blood limit: 5 nanograms/mL. Exceeding this while driving is a gross misdemeanor.
4. Child Passengers and Special Circumstances
It is illegal to vape or smoke in any vehicle used for transporting children, such as daycare vans.
There is currently no statewide law banning vaping with minors in a private car, but public health authorities strongly discourage it.
Some local jurisdictions may have additional rules—always check local regulations.
5. Minimum Age is 21
6. Public Places and Commercial Vehicles
Practical Tips and Considerations
If vaping distracts you while driving (fumbling with the device, large vapor clouds, etc.), you risk a ticket.
Never vape cannabis or drive under the influence of THC-containing products.
Avoid vaping in the presence of children in any vehicle.
Obey local laws, as some cities may add more restrictions.
Vaping nicotine while driving your own car in Washington is technically legal for adults, unless it causes distracted or unsafe driving. You may be fined if law enforcement sees vaping as contributing to dangerous driving.
Vaping marijuana while driving or allowing minors to vape is strictly illegal. For everyone’s safety—and to avoid any potential legal trouble—limit distractions and keep your attention on the road at all times.
