When is it permissible to turn right on red?

Turning right on red is permissible after coming to a complete stop and yielding to traffic. This practice ensures that drivers are aware of their surroundings before proceeding. When a driver stops completely at a red light, they can assess the situation for any pedestrians, bicycles, or vehicles that may have the right of way. Yielding to all traffic, including any that may be approaching from the left or straight through the intersection, is critical for safety. It is important for drivers to confirm that the path is clear before making the turn, which minimizes the risk of accidents and ensures compliance with traffic laws.

In contrast, a sign prohibiting a right turn on red explicitly indicates that at that particular intersection, turning is not allowed, regardless of the driver's intention to stop. The option suggesting a flashing light pertains to specific scenarios usually related to caution rather than indicating that turning is allowed. Additionally, immediately turning without stopping would disregard the necessary caution and observation that is vital for preventing collisions.
