What action should you take when you approach a yellow traffic light?

Answer: B — Prepare to stop if it is safe to do so

When approaching a yellow traffic light, the appropriate action is to prepare to stop if it is safe to do so. A yellow light indicates that the signal is about to change to red, which means you must be ready to take action. If you can safely stop your vehicle without risking a rear-end collision or being in the intersection when the light turns red, then stopping is the best choice. This principle is grounded in road safety guidelines, which emphasize the importance of being prepared for an imminent change in traffic signals. Vehicles should not accelerate to clear the intersection because that can lead to dangerous situations and violations of traffic laws. Continuing at the same speed or stopping immediately without considering safety can also result in risks to you and other drivers. Therefore, the key is to assess your surroundings and decide to stop only if it can be done safely.
