What is the action when the amber light is on?

When the amber light is on, it serves as a warning signal indicating that the traffic light is about to change to red. The proper action at this moment is to stop at the stop line if it is safe to do so. This allows vehicles that are already moving to clear the intersection but also ensures that new vehicles do not enter the intersection when the light is about to change, thus preventing potential accidents.

Stopping at the stop line when the amber light is active is crucial for safety and compliance with traffic regulations. Drivers should prepare to stop, ensuring that they do not rush through the intersection or make hasty decisions that could lead to dangerous situations. If a vehicle is already in the intersection when the amber light appears, it is acceptable for that vehicle to continue, but this does not apply to those approaching from behind who are still at the stop line.

Being aware of the purpose of the amber light reinforces the importance of following traffic signals to maintain safety on the roads.
