What does it mean when a red arrow displays with a green traffic light?

A red arrow displayed with a green traffic light typically indicates that drivers are not allowed to make a turn in the direction of the arrow, even though the green light allows for forward movement. This means that while vehicles can proceed straight through the intersection, they must stop and cannot turn in the direction of the red arrow. Always be sure to follow the specific traffic signals and rules in your area, as they can vary.
