20 Driving Habits Many People Get Wrong

Music in the car has come a long way from an AM radio with five preset buttons, but putting the sound directly into both ears introduces a different concern. Laws governing headphones and earbuds vary widely. Some states restrict wearing devices over both ears while driving, some allow one ear to remain covered, and others provide exceptions or have no specific ban. Legal or not, blocking outside sound can make a horn, siren, motorcycle, or unusual mechanical noise harder to notice.
