When can you cross a solid line?

Solid lines on the roadway are used to indicate that changing lanes or passing is prohibited. They serve as a clear visual cue to drivers that crossing these lines is not allowed under normal circumstances. This is particularly important for maintaining safety on the roads, as solid lines often mark areas where visibility is limited or where the risk of collision is heightened, such as near intersections or on curves.

Crossing a solid line could create dangerous situations, which is why the law enforces this restriction strictly. In certain specific circumstances, like emergencies or when instructed by law enforcement, there might be exceptions, but those situations do not negate the general rule for solid lines. Therefore, the safest practice is to adhere to the indication that solid lines mean no passing is allowed.
