Answer: B — Not change your lane

When you see a solid center line on your side of the road, it indicates that passing or changing lanes into oncoming traffic is prohibited. This traffic control marking is designed to enhance safety by preventing potentially dangerous maneuvers in areas where visibility or road conditions might make it unsafe to overtake another vehicle. The solid line signifies that drivers must remain in their lane and not cross over to the opposite lane. It is essential for maintaining traffic flow and minimizing accidents. Understanding this rule helps drivers make safer decisions on the road, particularly in situations where there's a high likelihood of encountering oncoming vehicles or other hazards. Recognizing the meaning of road markings is key to adhering to traffic laws and ensuring everyone's safety.
