You are 20 years old and driving. Your 15-year-old cousin rides in the back seat and does not want to buckle up. Under Pennsylvania law, who must make sure the cousin wears a seat belt?

Correct answer: You, because the driver must make sure passengers under 18 are buckled.

Why

Pennsylvania requires the driver and all front-seat passengers to wear seat belts, and passengers under 18 must be belted in every seat. Children under 8 need a child safety seat or a booster seat. A seat belt is the most effective way to reduce your risk of death or injury in a crash, because it keeps your body from hitting the inside of the car or being thrown out. A driver under 18 may not carry more passengers than there are seat belts.
