What does a double solid yellow line signify?

• A. No passing allowed in either direction
• B. Passing is allowed only for larger vehicles
• C. Passing is allowed in one direction
• D. It indicates a school zone

Answer: (A)

A double solid yellow line signifies that no passing is allowed in either direction. This marking is used to indicate that it is unsafe to cross the line for the purpose of overtaking another vehicle. The presence of a double solid yellow line means that drivers must remain in their lanes at all times, ensuring safety on roads where visibility may be limited or where there are other hazards. This rule applies universally, emphasizing the importance of traffic safety and adherence to road markings. Other markings, like broken lines or single solid lines, have different meanings regarding passing, but the double solid yellow line specifically prohibits passing entirely.
