This round red circle with a cross mark on the arrow warns that

1. Left turns are illegal

2. Right turns are illegal

3. All turns are prohibited

4. U-turns are mandatory

The correct answer is: Right turns are illegal

The round red circle with a cross mark on the arrow serves as a warning that specific turning movements are not allowed. In this case, the sign indicates that right turns are illegal at the intersection. This type of signage is used to clearly inform drivers that they cannot make a right turn, aiming to enhance safety and ensure a smoother flow of traffic in areas where right turns could create hazards or conflicts with pedestrian crossings or other vehicles. The other options reflect different kinds of prohibitive symbols that are distinct in meaning. For example, a sign indicating all turns prohibited would typically have a different design, such as a circle with a slash through a turning arrow, and a mandatory U-turn sign would be formatted to show the mandatory nature. Understanding these nuances in traffic signs is crucial for approaching and navigating intersections safely.
