What does the "No U-Turn" sign indicate?

Answer: B — U-turns are prohibited at that intersection

The "No U-Turn" sign clearly indicates that making a U-turn at that particular intersection is prohibited. This means that drivers are not allowed to turn their vehicles around to go in the opposite direction. The presence of this sign is intended to enhance safety by preventing potential collisions that could occur if drivers were allowed to make U-turns in areas where it could be dangerous, such as busy intersections or areas with limited visibility. Clear communication of traffic rules through such signage is crucial for maintaining orderly and safe driving conditions for everyone on the road. Regarding the other options: some may suggest that U-turns could be permitted or subject to specific requirements, but the "No U-Turn" sign definitively prevents any U-turn maneuver in that area, thereby ensuring clarity and safety for all road users.
