What should you do when approaching a pedestrian crosswalk with no traffic control signals?
Answer: B — Slow down and yield the right-of-way to pedestrians.
When approaching a pedestrian crosswalk with no traffic control signals, it is important to slow down and yield the right-of-way to pedestrians. This is because pedestrians have the right-of-way at crosswalks and it is important to ensure their safety. Speeding up to cross the crosswalk quickly (option A) puts pedestrians at risk and is not safe driving behavior. Honking your horn (option C) is also not necessary and could startle or frighten pedestrians. Continuing to drive without slowing down (option D) goes against proper traffic laws and could result in hitting a pedestrian. Therefore, option B is the safest and most appropriate choice.
