a signal that informs drivers that they must stop their vehicles
A red light in traffic is a signal that tells vehicles and pedestrians to stop. It is part of a traffic light system that controls movement to keep roads safe and organized. The red light appears after the yellow light and remains on for a set time before changing to green. Drivers must wait until the light turns green before moving forward or turning, unless a separate signal allows a turn. Traffic lights help prevent accidents and manage the flow of movement at intersections and crossings.
