What is the recommended action when approaching a yellow traffic light?

When approaching a yellow traffic light, the recommended action is to prepare to stop if it is safe to do so. A yellow light is a warning that the red light is about to appear, and it indicates that drivers should be ready to stop, as vehicles behind you may also be reacting to the signal change.

The key aspect of this recommendation is the emphasis on safety; the driver must assess the situation to determine if it's possible and safe to stop. If there is enough distance to stop safely without causing a hazard, the driver should do so. This approach helps prevent running a red light, which could lead to accidents.

In contrast, speeding up to clear the intersection can increase the risk of running a red light and may cause collisions. Continuing at the same speed does not account for the changing signal and puts the driver and others at risk. Slowing down regardless of conditions may not be appropriate if stopping safely isn't feasible; it could lead to abrupt maneuvers that could endanger surrounding vehicles. Thus, preparing to stop, while considering the safety of the situation, is the most prudent course of action.
