What does a steady green arrow allow drivers to do?

A steady green arrow indicates to drivers that they can proceed in the direction of the arrow while yielding to pedestrians and other vehicles. This signal grants a clear authorization to move forward, which means that drivers can safely navigate in the direction indicated without the need to stop, as long as they observe traffic conditions and yield to any right-of-way regulations such as pedestrians in crosswalks.

In this context, option B is not applicable because the green arrow does not require drivers to stop and wait; it actually allows them to proceed. Option C inaccurately limits the movement to turning left only, while the green arrow can apply to various directions depending on the traffic signal's specific placement. Lastly, option D suggests that a high speed is necessary, which is misleading; speed should always be appropriate for the road conditions and legal limits, regardless of the traffic signal.
