No, there is no law in Colorado making cursing while driving illegal. This appears to be another urban legend or mix-up with outdated or unverified “weird laws” lists, as no current statutes prohibit profanity from drivers.​
Actual Driving Laws
Colorado enforces a hands-free law (SB 24-065, effective 2025) banning manual use of mobile devices while driving, including texting, calls without hands-free, or browsing, with fines starting at $300 for adults. Drivers under 18 face total cell phone bans, and violations add points to licenses. Texting while driving remains a class 2 misdemeanor, escalating if it causes injury.​
Other Quirky Regulations
Profanity itself isn’t regulated on roads, but reckless driving from road rage could lead to charges under general traffic codes. Local ordinances in some areas target excessive noise like honking, but not speech. Distracted driving laws prioritize safety over verbal content.
