What should a driver do when approaching a double solid line?

When approaching a double solid line, the appropriate action is not to cross the line. This traffic marking indicates that lane changes are prohibited in both directions. The double solid lines serve an important safety purpose by preventing drivers from making unsafe maneuvers that may lead to collisions or other dangerous situations.

It is essential for drivers to adhere to these markings to maintain traffic flow and ensure the safety of all road users. For instance, crossing a double solid line to change lanes or pass another vehicle can create confusion and increase the risk of accidents. In contrast, lines that are broken or single solid may indicate different regulations where lane changes may be allowed under certain conditions. Therefore, the presence of double solid lines explicitly instructs drivers to stay in their lane and refrain from crossing them.
