In Colorado, vaping nicotine while driving is not explicitly illegal, but it is subject to important safety and conduct regulations. If you choose to vape behind the wheel, you must ensure it does not compromise your ability to operate the vehicle safely or violate specific protections regarding passengers.
Distracted Driving and Safety
While state law does not outright ban vaping, Colorado prohibits distracted driving. If law enforcement determines that your vaping activity—such as managing the device or dealing with significant vapor clouds—has impaired your focus or obstructed your visibility, you can be cited for distracted driving or unsafe operation.
Maintaining a clear line of sight is critical, as large clouds of vapor can temporarily block your view of the road or mirrors. Furthermore, if your actions behind the wheel lead to an accident, vaping could be cited as a contributing factor, potentially complicating insurance claims or legal liability.
Minors and Passenger Restrictions
One of the most critical legal restrictions involves the presence of minors in your vehicle. Colorado law strictly prohibits smoking or vaping in a motor vehicle if a minor under the age of 18 is present.
This is treated as a child endangerment concern, and drivers found in violation can face significant penalties. Additionally, while your car is generally considered a private space, local jurisdictions or specific vehicle regulations may impose their own restrictions, so it is always wise to be aware of the environment and the passengers accompanying you.
Marijuana Vaping is Illegal
It is essential to distinguish between vaping nicotine and vaping marijuana. Under Colorado law, using marijuana in any form—including vaping—while driving is strictly prohibited. This law applies regardless of the driver’s level of impairment.
Colorado also enforces strict “open container” laws for marijuana, meaning that any cannabis product must be kept in a fully sealed container while in the vehicle. If a driver has 5 nanograms or more of delta-9 THC per milliliter of whole blood, they can be charged with driving under the influence (DUI) or driving under the influence of drugs (DUID).
Because this threshold can be reached with relatively small amounts of consumption, the safest legal stance is to avoid any marijuana use before or while operating a vehicle.
