What does a double line indicate?

A double line on the roadway serves as a clear indication that passing is prohibited. This is crucial for maintaining safety on the road, especially in areas where visibility is limited or where the road conditions may pose hazards. The double line typically signifies that there is a substantial risk involved in changing lanes or overtaking another vehicle, hence the strict rule against it.

The presence of this marking helps to prevent accidents by discouraging drivers from attempting to pass when it's unsafe. It is a visual cue that reinforces the importance of adhering to traffic laws designed to promote safe driving behaviors. Recognizing such signals is essential for drivers to navigate the roads responsibly and avoid situations that may lead to collisions.
