What action should a driver take when encountering a green arrow on a lane control signal?

When a driver encounters a green arrow on a lane control signal, it signifies that the lane is open and designated for use. This signal specifically indicates that traffic is allowed to proceed in the direction of the arrow, indicating that it is safe for vehicles to utilize that lane without concern for oncoming traffic or other impediments.

This green arrow serves as a clear directive to drivers, helping to manage roadway efficiency and safety by guiding them on where they can travel. While it’s important to always be mindful of conditions such as pedestrians or cyclists, the primary function of the green arrow is to assure drivers that the lane is indeed available for their use.

In contrast, the other responses do not align with the implications of a green arrow. Changing lanes without consideration of traffic is risky and not recommended; preparing to stop contradicts the directive of the signal, and yielding to oncoming traffic would not be necessary when the green arrow indicates that the lane is clear. Thus, the correct interpretation emphasizes the safety and utility of proceeding in accordance with the green arrow signal.
