A lighted green arrow over the traffic lane indicates what?

A lighted green arrow over a traffic lane indicates that you may use that lane. The green arrow signals to drivers that they have the right of way in that specific direction and can safely proceed. This is designed to help traffic flow smoothly and to provide clear guidance to drivers about the permitted movements at an intersection.

The presence of the green arrow is particularly important in complex intersections or when turning, as it reduces confusion and enhances safety by clarifying that vehicles in that lane can move forward or turn, depending on the context of the signal. Drivers can rely on the green arrow to know that other vehicles are expected to yield, which helps in making driving decisions without the need for further caution.

While other options may involve restrictions or suggest regulatory conditions, a lighted green arrow unequivocally allows for movement in that lane, establishing it as the appropriate response for navigating that part of the roadway safely.
