Which statement about passing lines is false?

In the context of road rules, it's important to understand the implications of lane markings and their meanings. Single lanes are typically designed for traffic in one direction. When you have a single lane, it may not be legally permissible for a vehicle to pass another vehicle due to the restrictions of the road layout and safety concerns.

The statement indicating that it is legal for a car in a single lane to pass implies that a vehicle can overtake another vehicle within that designated space, which may not be safe or lawful depending on the specific circumstances of the road and traffic conditions. In many scenarios, passing in a single lane violates traffic laws designed to ensure safety, particularly when visibility is limited or if passing zones are designated.

On the other hand, the other statements accurately represent lawful behaviors regarding passing lines. It is indeed legal to pass over a dashed white line, as this line indicates that lanes are open for changing. The double yellow line allows for crossing when turning into a driveway, given the right-of-way rules are observed. Therefore, the only statement that contradicts established road rules and safety is related to passing in a single lane.
