Is it legal to make a U-turn across a solid yellow line?

Answer: B — No, it is illegal

Making a U-turn across a solid yellow line is illegal because solid yellow lines indicate that passing or crossing is prohibited. These lines are used to signal that the area is either too dangerous for such maneuvers due to visibility issues, the presence of oncoming traffic, or other potential hazards. When a driver encounters a solid yellow line, they are required to adhere to the traffic regulations that prohibit crossing it. This law is in place to ensure safety on the road by preventing risky maneuvers that could lead to accidents. Therefore, it is important for drivers to recognize and respect these markings when navigating the streets.
