When approaching a yellow traffic signal, you should?

Answer: D — Slow down

When approaching a yellow traffic signal, you should slow down. This option provides the safest course of action when confronted with a yellow light. Stopping abruptly at a yellow light can cause accidents due to other drivers not expecting you to stop. Increasing your speed is also not recommended as it may lead to running a red light and causing a collision. Turning around is not a viable option since you are already in the intersection, and it may not be safe to do so. Therefore, slowing down is the best option when approaching a yellow traffic signal.
