What does a double solid line in the center of the road mean?

Answer: C — No passing is allowed in either direction

A double solid line in the center of the road indicates that no passing is allowed in either direction. This marking serves as a clear warning to drivers that crossing these lines to overtake another vehicle is prohibited, ensuring safety on the road. The use of double solid lines is specifically designed for areas where visibility may be limited or where passing could create dangerous situations, such as on curves, hilltops, or in heavy traffic. The presence of these lines reinforces the importance of adhering to traffic rules that prioritize the safety of all road users. Motorists should remain vigilant and respect these markings to help prevent collisions and maintain the flow of traffic safely.
