What does a "no turn on red" sign indicate?

A "no turn on red" sign clearly indicates that drivers are not permitted to make a right turn at a red traffic light. This restriction is in place for safety reasons, often due to visibility issues, pedestrian crossings, or the configuration of the intersection that may pose hazards to those turning or crossing. The sign helps ensure that drivers remain cautious and yield to any oncoming traffic or pedestrians before proceeding. Understanding this signage is crucial for maintaining the flow of traffic and ensuring safety at intersections.
