Are U-turns permitted on expressways?

Answer: A — No, they are not legal

Expressways are high-speed roads with multiple lanes and are designed to be efficient for drivers to reach their destination quickly. Therefore, it is not safe to make a sudden U-turn on an expressway as it can disrupt the flow of traffic and cause potential accidents. This is why U-turns are not legal on expressways, making option A the correct answer. Additionally, options C and D are incorrect because even if there are certain times or right of way, U-turns are still not permitted on expressways. Option B may seem feasible as expressways do have exits and entrances that may allow for a U-turn, but overall, U-turns are prohibited on expressways for the safety of all drivers.
