The “Do Not Cross” sign with a solid striped line is a regulatory traffic sign seen on Canadian roads, especially in areas with painted solid lane markings. It serves to reinforce the rule that crossing a solid line is illegal and dangerous. This sign is often tested in the Ontario G1 driving test and is crucial for safe lane discipline.
