Delaware Defensive Driving Practice Test

When traffic signals are not functioning, it indicates that there is a failure in the traffic control system, which can create hazardous conditions for drivers approaching the intersection. Treating the intersection as a four-way stop is the appropriate action in this scenario. This means that all vehicles approaching the intersection must stop, and then yield the right of way according to established rules: typically, the first vehicle to arrive at the stop line has the right of way, but if two vehicles arrive simultaneously, the vehicle on the right has the right of way. This procedure helps manage the flow of traffic safely and reduces the risk of collisions in the absence of functioning traffic signals, ensuring that all drivers are aware of their responsibilities to stop and proceed with caution. Taking any other action, such as continuing to drive as usual or yielding only to particular directions, could lead to confusion and increased danger at the intersection. Thus, treating the intersection as a four-way stop is the safest course of action when traffic signals are out.
