In New Hampshire, as of 2025, it is not specifically illegal for adults (21 and older) to vape while driving. The state does not have a law that explicitly bans vaping in vehicles for adults. However, vaping could fall under the broader category of distracted driving if it impairs your ability to operate the vehicle safely. For example, if vaping causes you to take your eyes off the road, handle your device excessively, or if the vapor obstructs your view, law enforcement may cite you for distracted or reckless driving.
New Hampshire enforces a hands-free law for mobile devices, but vape devices are currently not classified as communication or data-entry devices, so this law does not directly apply to vaping. Despite this, the core principle remains that drivers must maintain full control and attention.
For individuals under 21, possession or use of vaping products, including while driving, is illegal.
A bill proposing to prohibit vaping or smoking in vehicles when passengers under 16 are present was introduced but did not pass as of 2025.
To sum up:
- Adults can legally vape while driving, provided it does not create a distraction.
- Vaping that causes unsafe driving can lead to distracted driving citations.
- Underage vaping while driving is illegal.
- No current law bans vaping in cars with minors present, but such exposure is discouraged.
The best practice is to avoid vaping while driving to prevent distractions and maintain safety on the road.
