If traffic lights are out, which of the following should you do?

When traffic lights are out, treating the intersection as if there is a stop sign is the appropriate action to take. This means that all vehicles must come to a complete stop and yield to any traffic that may be present. This approach ensures safety by preventing accidents that could occur in a confused intersection where drivers may not know who has the right-of-way.

By treating the situation like a stop sign, drivers can assess the intersection and proceed only when it is safe to do so. This method fosters a level of predictability and order among drivers, who all know to stop before entering the intersection.

The other choices may lead to confusion or unsafe situations. Following the lead of other drivers could result in erratic behavior, as not all drivers may react similarly. Assuming the intersection is clear is dangerous, as it disregards the possibility of oncoming traffic or pedestrians. Stopping and waiting for police direction could unnecessarily delay traffic and create further complications if law enforcement is not present to manage the intersection. Therefore, treating the intersection as if there is a stop sign is the safest and most effective course of action.
