What is the recommended action when approaching a "stale" green light?

The recommended action when approaching a "stale" green light is to cover the brake and be prepared to stop. This is considered the safest approach because a "stale" green light indicates that the signal has been green for some time and may soon change to yellow or red. By covering the brake, the driver can quickly reduce speed and stop if the light changes unexpectedly, thus increasing safety for both the vehicle and any pedestrians or other vehicles that may be crossing the intersection.

Speeding up to clear the intersection can be dangerous because it may not allow for sufficient reaction time if the light changes or if there are unforeseen obstacles in the road. Assuming the light will stay green is risky, as it disregards the possibility of a sudden change in signal, which could result in a traffic accident. Activating emergency lights is typically reserved for situations where immediate action is required, such as responding to an emergency. In the case of approaching a stale green light, it is more prudent to prepare for a possible stop.
