No, cursing while driving is not against the law in Oregon. The claim appears to be a misconception or mix-up with Rockville, Maryland, where a municipal ordinance prohibits profane cursing or obscene language near streets or highways if audible to passersby.
Rockville, MD Law
Rockville’s code (Sec. 13-53) makes it a misdemeanor to “profanely curse and swear or use obscene language upon or near any street, sidewalk or highway within the hearing of persons passing by.”
This can apply to drivers if profanity is heard by pedestrians or others, with potential fines up to $100 or 90 days in jail, though enforcement is rare.​
Oregon has no equivalent statute; its vehicle laws cover false swearing in licensing contexts only, unrelated to road profanity.​
Oregon Driving Laws
Oregon bans distracted driving like texting but nothing specific to cursing.​
Other quirky Oregon rules exist, such as not discarding urine containers on highways.​
Road rage elsewhere (e.g., California) requires threats or weapons, not mere swearing.
