What does a red traffic signal mean?

A red traffic signal indicates that drivers must stop their vehicles and wait for the signal to turn green before proceeding. This signal is critical for maintaining order and safety at intersections, preventing accidents by clearly communicating to drivers that they must halt their movement. It contrasts with other options, which either suggest actions that could lead to confusion or danger. Yielding to pedestrians, for instance, is relevant when a vehicle is already stopped, but when a red light is present, the priority is to stop completely. Similarly, phrases like "proceed with caution" or "turn around and go back" are not appropriate actions when facing a red traffic signal; they could disrupt traffic flow and increase the risk of collisions. Understanding the meaning of the red signal is fundamental for all drivers as it ensures compliance with traffic laws and enhances road safety for everyone on the road.
