What does a green arrow on a traffic light signify?

A green arrow on a traffic light signifies that you may proceed in the direction of the arrow. This indication allows drivers to move confidently without needing to stop, as it grants the right of way for the designated direction of travel. In many situations, such as at an intersection, a green arrow means that it is safe to turn left or right, depending on where the arrow is pointing, and other vehicles or pedestrians must yield.

Understanding this signal is crucial for safe driving, as it helps to facilitate the flow of traffic and prevents misunderstandings at intersections. The other options relate to different traffic signals: stopping is necessary for a red light, preparing to stop is associated with a yellow light, and yielding to oncoming traffic typically occurs when turning left at intersections without a green arrow. Therefore, recognizing what a green arrow represents promotes safer driving decisions and reduces the likelihood of accidents.
