Final Answer:
The presence of a long black arrow on a yellow sign indicating "No U-turn" is rooted in standardized traffic control and safety practices. Therefore, the correct answer is option 3) No U-turn
Step-by-step explanation:
When you see a long black arrow on a yellow sign, it means **No U-turn**. This specific road sign is a universal symbol indicating that making a U-turn is prohibited in the designated area. The long black arrow emphasizes the restriction on making a U-turn, directing drivers to proceed without turning back in the indicated location.
This sign is crucial for traffic management and safety, providing clear guidance to drivers about the allowed or restricted maneuvers at a particular location. The prohibition of U-turns is often implemented in areas where such maneuvers could pose a risk to the flow of traffic or where visibility is limited. Therefore, recognizing and adhering to this road sign contributes to the overall safety and efficiency of traffic movement.
Understanding and obeying road signs are fundamental aspects of responsible driving. The distinctive features of each sign, including the color, shape, and symbols, convey specific messages that drivers must interpret and follow for the safety of themselves and others on the road. In the case of a long black arrow on a yellow sign, it serves as a clear indication that making a U-turn in that area is not allowed, prompting drivers to navigate accordingly.
