What does a red traffic light signify?

A red traffic light signifies that drivers must come to a complete stop at the intersection or the traffic signal. This rule is in place to ensure safety because the red light indicates that it is not safe to proceed; there could be cross traffic from the opposite direction that has the right of way. Adhering to the red light helps prevent accidents and maintain orderly traffic flow.

While there are other signals and situations where drivers might need to slow down or prepare to stop, a red light specifically demands a full stop before the intersection. This is a critical part of understanding traffic signals, as ignoring a red light can lead to serious violations and accidents.
