What is the meaning of a green arrow pointing left at an intersection?

A green arrow pointing left at an intersection indicates that drivers are permitted to turn left while oncoming traffic is stopped. It indicates a favorable condition for a left turn, meaning that there are no restrictions and it is safe to proceed. The presence of the green arrow typically implies that other traffic signals or conditions are indicating that vehicles facing oncoming traffic should be stopped, thus clearly establishing a right of way for the left-turning driver.

Understanding traffic signals is crucial for maintaining safety at intersections. A green arrow specifically provides a clear directive to drivers, differentiating it from other signals like a green light without an arrow, which may have additional considerations such as oncoming traffic. Therefore, recognizing this signal allows drivers to make informed decisions quickly, ensuring a smoother flow of traffic and enhanced safety for all road users.
