When must you wear a seat belt?

Answer: C — At any time while driving

Wearing a seatbelt is always important while driving, regardless of the road you are on or the traffic conditions. This is because car accidents can happen at any time and at any speed. So while it is required by law to wear a seatbelt on highways, it should also be a habit to keep it buckled up at all times while driving. It is incorrect to say that it is only necessary during rush hour or in parking lots, as accidents can happen in these scenarios as well.
