What does a green arrow in a traffic light mean?

A green arrow in a traffic light indicates that you may proceed in the direction of the arrow. This signal allows drivers to move forward safely, typically after yielding to other road users such as pedestrians or cyclists, who may have their own signals. The green arrow is often accompanied by a red light for other lanes of traffic, allowing for a protected movement in the direction of the arrow, which enhances vehicular and pedestrian safety. It is important to follow this signal as it clearly guides drivers on when they can proceed without the need to stop or yield further, aside from ensuring the intersection is clear of obstacles.
