What action is required when approaching a solid white line?

When approaching a solid white line, the appropriate action is to understand that this line is used to indicate that changing lanes is discouraged and should be avoided. Solid white lines are typically found on the right edge of the roadway to delineate lanes or to indicate where passing is not allowed. The intention behind this marking is to promote safety by discouraging maneuvers that could lead to collisions.

It's essential for drivers to recognize that the presence of a solid white line signifies that they should remain in their lane and refrain from making any lane changes. This understanding is crucial in ensuring the safety of all road users.
