The legality of wearing headphones while driving varies by state. No state has a complete ban, but many have restrictions. Arizona, Texas, and others have no limits at all. Louisiana and California prohibit headphones covering both ears, allowing one earbud. Colorado only permits one earbud for phone calls.

Even where allowed, wearing headphones poses safety risks by blocking important sounds like sirens and honks. It can lead to distracted driving citations or legal liability in accidents, even if you're not at fault. Contributory negligence laws may reduce payouts.

Cars have built-in speakers or easily added adapters, making headphone use unnecessary. Overall, the risks outweigh any benefits, so it's best to avoid driving with headphones.
