What does a double solid line indicate?

A double solid line indicates that no passing is allowed in either direction. This traffic marking is used to enhance safety by preventing drivers from overtaking and passing other vehicles, which can be particularly dangerous in areas where visibility is limited or where there may be a higher likelihood of collisions.

The presence of double solid lines signifies a clear and definitive rule: regardless of the circumstances, drivers must stay in their lanes and not attempt to pass another vehicle. This helps maintain the flow of traffic and reduces the risk of accidents. Understanding this rule is crucial for safe driving and compliance with road regulations.
