What must you do at an intersection when the light turns red?

When the traffic light turns red at an intersection, the appropriate action is to prepare to stop. Traffic lights are designed to control the flow of vehicles and ensure safety at intersections. A red light indicates that vehicles must stop before the intersection to allow for safe passage of those who are crossing on a green light.

Preparing to stop means that you should decelerate in a controlled manner and be ready to halt completely at the stop line or before entering the intersection if there is no dedicated stop line. Stopping at a red light is crucial for preventing accidents and ensuring that all road users, including pedestrians and cyclists, can navigate the intersection safely.

Engaging in other actions, such as speeding up to cross before the light changes, proceeding with caution, or turning right without checking, can lead to violations of traffic laws and pose significant risks to yourself and others on the road. It is essential to follow traffic signals closely to maintain safety and uphold the law.
