What action should be taken when approaching a red traffic light?

When approaching a red traffic light, the action that should be taken is to come to a complete stop. This is a critical traffic law designed to ensure safety at intersections. A red light indicates that vehicles must not proceed through the intersection, allowing pedestrians to cross safely and preventing collisions with cross traffic.

Stopping at a red light also allows drivers to assess their surroundings. They can check for any pedestrians or cyclists who may be crossing the street, as well as prepare to make informed decisions once the light turns green. This adherence to the traffic signal helps maintain order and predictability on the road, which is essential for all road users.

The other options are not appropriate actions for approaching a red light, as doing so could lead to dangerous situations or violations of traffic laws.
