What are the benefits of using a seat belt?

Answer: A — Prevents injury during a crash

Using a seat belt is important because it helps prevent injury during a crash. Option B, driving on the freeway, and option D, driving faster, do not necessarily apply to the use of a seat belt and do not provide health benefits. Option C, keeping you from getting a ticket, is a consequence of not wearing a seat belt but is not the main benefit. Therefore, the correct answer is A.
