It is against traffic laws to be wearing anything on your ears in many places. I got pulled over in Colorado in around 2010 for having one ear of a wired headset on. Didn’t get a ticket, but still sucked.
It’s something about being able to hear sirens and stuff around you. It’s dumb because people will blast music as loud as they want but having one ear covered gets you in trouble.
Oh, I know. And I wonder how many people with large hearing aids get pulled over too.
