No, cursing while driving is not against the law in West Hawaii (or anywhere in Hawaii). This appears to be another urban myth from “dumb laws” lists, with no supporting statute in Hawaii’s penal or traffic codes.
Actual Hawaii Driving Laws
Hawaii enforces standard distracted driving rules under HRS §291-031, banning handheld cellphone use, texting, and (for drivers under 18) any mobile device operation, with fines starting at $100-$200 for first offenses. Obscenity laws like HRS §712-1211 target public displays of indecent visual matter (e.g., explicit billboards exploiting lust), not verbal profanity from vehicles. Indecent exposure (§7-9-19) covers willful genital displays in public view, unrelated to speech.
Myth Context
Viral tales often misattribute old ordinances; Hawaii prioritizes road safety via seatbelts, DUI limits (0.08% BAC), and no left-on-red turns, but free speech protects most roadside cursing absent direct threats. No “West Hawaii”-specific ban exists—county rules align statewide.
