What action is required when a vehicle encounters a red arrow?

When a vehicle encounters a red arrow, the correct action is to come to a complete stop. This traffic signal specifically indicates that the driver must stop and is not permitted to proceed in the direction of the arrow until it turns green or is otherwise directed to go. The red arrow functions similarly to a red traffic light, signaling that the path of movement in that direction is prohibited.

It's essential for drivers to fully stop at the red arrow to ensure safety, as proceeding without stopping could lead to collisions with other vehicles or pedestrians. Once the arrow changes, or if there are specific signs indicating otherwise, the driver may then proceed safely. Understanding this rule is vital because disregarding the red arrows can lead to traffic violations and dangerous situations on the road.
