What does a green arrow signal allow a driver to do?

A green arrow signal indicates that a driver has the right of way to proceed in the direction that the arrow is pointing. This means that when you see a green arrow, you are authorized to turn in that specific direction, provided it is safe to do so and no other traffic laws are being violated.

For example, if there is a green arrow pointing left, drivers can make a left turn without yielding to oncoming traffic or pedestrians, assuming there are no additional signs that alter this rule. The green arrow effectively communicates that the turn is permitted and that the driver can proceed confidently in that direction.

In the context of traffic signals, other options do not align with the meaning of a green arrow. Speeding up is not a function of a green arrow; instead, it emphasizes safe navigation through the intersection. Stopping completely is typically required for red lights or stop signs, while U-turns may not be permitted where a green arrow is present unless explicitly stated by signage.
