What is the meaning of a green arrow traffic signal?

A green arrow traffic signal clearly indicates that a driver may proceed in the direction that the arrow is pointing. This means that the route is safe to travel and has right-of-way against any other traffic indicators, such as red lights or stop signs in other directions. The green arrow signals that it is legal and safe to make a turn or drive straight, depending on the placement of the arrow.

In terms of understanding other options, stopping and yielding to vehicles would apply to a yellow light or a steady red light, which instruct a driver to prepare to stop or yield before proceeding. "Proceed with caution" generally aligns with a yellow light, which suggests a change in the traffic signal state is imminent. Waiting for the light to turn green applies when a signal is red and indicates that drivers must remain stopped until they receive the appropriate signal to proceed. Each of these alternatives serves a specific purpose regarding traffic flow and safety, distinctly separate from the clear directive offered by a green arrow.
