Yes—for most adults in a private car, vaping nicotine is not specifically banned in Colorado, but you can still get in trouble if it becomes distracted driving or involves cannabis, minors, or an open-container issue. Colorado also now has a statewide hands-free law for phones, and general careless-driving rules can still apply if vaping affects safe driving.
What Colorado law allows
Colorado does not have a blanket statewide law that says adults cannot vape nicotine while driving a private vehicle. A 2025 review of Colorado vaping rules notes that the state’s indoor vaping restrictions target public places, not ordinary private cars, and another 2025 guide explains that adult vaping in a private vehicle is generally allowed unless other laws are triggered.
Where it becomes illegal
Vaping can become unlawful if it creates unsafe driving conditions, because Colorado’s careless-driving law covers driving “in a careless and imprudent manner” without due regard for traffic and road conditions. In practical terms, an officer could cite you if taking a hit, handling a device, or blowing a dense cloud causes you to swerve, look away from the road, or drive unsafely.
Cannabis rules matter
The rules are much stricter for marijuana. Colorado guidance says neither drivers nor passengers may use cannabis in a vehicle, and cannabis use in a car can also lead to DUI or open-container trouble under state law.
Minors in the car
If a child is in the vehicle, the risk goes up. Colorado and public-health summaries indicate that smoking or vaping in a car with a minor is prohibited or treated as unlawful under the state’s clean-indoor-air and child-safety framework.
