What does a solid white line with a lane turn arrow indicate?

A solid white line with a lane turn arrow indicates that the lane is designated for turning and discourages lane changes. This means that drivers should remain in that lane if they intend to make a turn, and they should not cross the solid line to change into or out of that lane. The use of a solid white line reinforces the idea that this lane serves a specific purpose — to direct traffic as it must turn — and aims to enhance safety by minimizing the risk of collisions that could occur from sudden lane changes.

The other options describe scenarios that do not apply to the purpose of a solid white line with an arrow. For example, such a line doesn’t indicate passing lanes since passing is typically discouraged in areas where a solid line is present. It also does not denote a parking zone, as parking zones are usually marked differently and require different types of line markings. Lastly, while pedestrian crossings may involve line markings, they are not represented by solid white lines with turn arrows specifically.
