What is the meaning of a flashing red light?

A flashing red light has a specific meaning in traffic control that requires drivers to take immediate action for safety. It signifies that a driver must come to a complete stop, just as they would at a stop sign. After stopping, the driver is permitted to proceed through the intersection, but only after ensuring that it is clear and safe to do so. This regulation helps prevent accidents by ensuring that vehicles give way to any existing traffic or pedestrians that may be present before continuing.

The other options describe scenarios that do not align with traffic control standards or the meaning of a flashing red light. For instance, a pedestrian activated light is usually a different color and has a different function related to pedestrian safety. Similarly, a trolley crossing does not correspond to the implications of a flashing red light, and the mention of a fictional character adds an element of humor but has no basis in traffic signaling.
