What does a red traffic light indicate?

A red traffic light indicates that you must stop. This is a universal traffic signal intended to control the flow of vehicles and ensure safety on the roads. When drivers see a red light, it means they are required to bring their vehicle to a complete stop before the intersection or a marked stop line.

This rule is crucial because it prevents collisions and allows pedestrians to cross safely when the crosswalk light may be activated. Understanding the function of a red light helps ensure that all road users adhere to traffic laws, promoting safety and order on the road.

Options that suggest proceeding, preparing to turn, or making a U-turn misinterpret the fundamental purpose of the red light, which is solely to instruct drivers to stop. Following this signal is essential to maintaining road safety.
