What does a red traffic light signify?

A red traffic light signifies that drivers must come to a complete stop at the intersection. This is a crucial traffic signal designed to manage the flow of vehicles and ensure safety at crossings. When the light is red, it indicates that it is not safe to proceed, allowing pedestrians to cross safely and other traffic to flow in the direction permitted by their green signals.

Understanding this rule is vital for both highway safety and compliance with traffic laws. Ignoring a red light can lead to serious accidents and legal penalties. Drivers should always remain vigilant and ensure that they stop fully when the light is red, checking for any additional signals or road signs indicating whether a turn may be permissible after stopping, or if they should stay in place until the signal changes.
