What does a traffic light showing a red light and a green arrow allow you to do?

A traffic light displaying a red light along with a green arrow permits drivers to turn in the direction of the green arrow only. This signal indicates that while the intersection is temporarily restricted from general traffic due to the red light, specific turns are allowed where indicated by the green arrow.

For example, if the green arrow points right while the light is red, drivers can safely turn right without violating traffic laws. It's important to always check for pedestrians and other vehicles before making such a turn to ensure safety.

Turning in any direction or making a U-turn would be prohibited as they are not allowed under a red light, even if there is a green arrow present. Additionally, proceeding straight is not permitted under these circumstances, as the red light restricts straight movement unless there are specific traffic signals indicating otherwise.
