What does a red arrow mean?

A red arrow indicates that drivers must stop and may not proceed in the direction that the arrow is pointing. This traffic signal serves the same function as a solid red light, indicating that the road is closed to traffic in that direction until the signal changes to a more permissive indication. It is essential for maintaining safety on the road, as it prevents vehicles from entering intersections or areas where movement would be dangerous or illegal.

The requirement to stop ensures that drivers yield to pedestrian traffic and other vehicles that may have the right of way. Understanding and obeying red arrows is crucial for drivers to navigate intersections safely and avoid accidents.
