What should a driver do when approaching an intersection with a stale green light?

Answer: C — Approach with caution

When approaching an intersection with a stale green light, the most prudent course of action is to approach with caution. A stale green light indicates that the light has been green for some time, which increases the likelihood that it may soon change to yellow or red. By approaching cautiously, a driver can better assess the situation, check for any possible hazards, and prepare to stop if necessary. This cautious approach allows for greater awareness of the intersection and the behavior of other drivers and pedestrians, ultimately enhancing safety. In contrast, speeding up to cross quickly may lead to running a red light if the signal changes unexpectedly, while continuing through without caution could result in an accident. Coming to a complete stop may not be necessary if it is safe to proceed, but it could cause unnecessary delays if the light is still functioning properly. Therefore, exercising caution is key to safe navigation through intersections with stale green lights.
