What does a green arrow mean in a traffic light?

A green arrow in a traffic light indicates that drivers can proceed in the direction of the arrow. This signal provides a clear directive to drivers, allowing them to enter an intersection and continue moving without the need to stop, as long as it is safe to do so. Essentially, the green arrow functions as a right-of-way indicator, meaning that traffic in that direction has priority and that vehicles are allowed to proceed while other signals may indicate stopping or yielding.

Understanding this is essential for safe driving, as it helps ensure that drivers are aware of their rights and responsibilities at intersections. It's important to note that while the green arrow permits movement in the designated direction, drivers must still be vigilant for pedestrians, cyclists, or other vehicles that might be present in the intersection.
