What type of line is used to separate one-way traffic?

The correct answer indicates that a solid white line is used to separate one-way traffic. A solid white line typically signifies that lane changes are discouraged or prohibited, helping to maintain the flow of traffic in the same direction. This enhances safety by reducing confusion among drivers about the allowable movements on the road. In areas where traffic flows in only one direction, the solid white line marks the boundaries of that traffic, providing clear guidance for drivers.

In contrast, other line types serve different purposes. For example, a solid yellow line generally separates lanes of traffic moving in opposite directions, while a broken white line indicates that lane changes are permitted. A broken yellow line allows for passing in specific situations, typically in two-way traffic scenarios, but it does not apply to one-way situations. Understanding the appropriate uses of different line types contributes significantly to road safety and effective navigation.
