Under what conditions can you make a U-turn?

Answer: B — When it is safe and not prohibited by signs

The ability to make a U-turn is typically regulated by traffic laws to ensure safety and compliance with local regulations. Making a U-turn is permissible when it is safe to do so and not explicitly prohibited by signage. This means that the area must be clear of oncoming traffic, pedestrians, and any obstacles, and there should be no posted signs indicating that U-turns are not allowed. Options suggesting that you can make a U-turn whenever you want, only at traffic lights, or in any intersection do not take into account the important safety considerations and legal restrictions that govern this maneuver. Always ensuring that a U-turn is safe and allowed by signs helps prevent accidents and promotes orderly driving behavior.
