In what situation is it permissible to change lanes over a solid white line?

Changing lanes over a solid white line is never permissible because solid lines indicate that lane changes are discouraged or prohibited. This rule exists to maintain road safety, as solid white lines often demarcate lanes where it may be hazardous to switch lanes, such as areas near intersections, pedestrian crossings, or where the road width may change. The intention is to avoid confusion and ensure that drivers remain in their designated lanes to prevent accidents or disruptions in traffic flow. Road signs and markings are established for a reason, and adherence to these markings is crucial for safe driving practices.
