As vaping continues to be a common practice, many New Hampshire residents and visitors find themselves wondering about the specific rules surrounding e-cigarette use while behind the wheel. Is it legal to vape and drive in the Granite State? The straightforward answer is that, as of 2025, New Hampshire does not have a specific state law that explicitly prohibits adults from vaping while driving. However, this doesn’t mean it’s a complete free-for-all. Important restrictions, particularly concerning distracted driving and underage use, must be understood to avoid potential legal issues.
