No, cursing while driving is not illegal in Delaware under state law. The notion stems from urban legends about “dumb laws,” but no specific statute bans profanity from vehicles.
Relevant Laws
Delaware’s motor vehicle code (Title 21) covers distractions, reckless driving, and road rage but lacks provisions targeting swearing. General disorderly conduct (11 Del. C. § 1301) requires intent to cause inconvenience or alarm in public, rarely applied to solo drivers venting.​
Urban Legend Context
Online lists exaggerate old nuisance ordinances, but modern enforcement focuses on actions like aggressive gestures, not words alone. School bus rules prohibit profanity among pupils, not adult drivers.
