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

The presence of a "no turn on red" sign indicates that drivers must wait for a green light before turning. This is a traffic regulation designed to ensure the safety of pedestrians and other vehicles that may be present at the intersection. By requiring drivers to wait for the green signal, it facilitates a smoother flow of traffic and reduces the likelihood of accidents that can occur when vehicles turn while facing a red light.

While a "no turn on red" sign may imply that turns, in general, are prohibited when the traffic signal is red, it specifically emphasizes the importance of waiting for the appropriate signal to proceed safely through the intersection. This helps to clarify that turning right or any form of turning is not permitted during red lights, thereby promoting adherence to traffic laws and enhancing road safety for everyone involved.
