When must you wear a seatbelt while driving?

Answer: A — Anytime

While option D may seem like a good choice, it is important to wear a seatbelt even when the vehicle is just starting to move or when coming to a stop. This reduces the risk of injury in case of sudden stops or collisions. Option B and C are incorrect because seatbelts should be worn at all times, regardless of the time of day. It is always better to be safe than sorry. So, option A is the most appropriate and safest answer.
