Louisiana Class D Chauffeur's License Practice Test

What do you do when the traffic lights are not working?

1. Proceed with caution without stopping

2. Treat the intersection as a four-way stop

3. Wait for the lights to start working

4. Signal your turn and continue

The correct answer is: Treat the intersection as a four-way stop

When traffic lights are not working, treating the intersection as a four-way stop is the appropriate response. This action is in accordance with traffic laws that ensure safety and order during situations where signals fail. Each vehicle approaching the intersection must come to a complete stop, which allows for a clear right-of-way determination among drivers. Vehicles must yield to those that arrived first and follow the basic rules of a stop intersection, ensuring that all drivers understand who has the right of way. This practice minimizes confusion and reduces the likelihood of accidents, as it creates a predictable environment for all road users. In contrast, proceeding with caution without stopping could lead to misunderstandings about who has the right of way, potentially resulting in accidents. Waiting for the lights to start working may not be practical or safe, especially if other vehicles are present and moving through the intersection. Signaling a turn and continuing without stopping could create hazardous conditions if other drivers are not aware of your intentions, further complicating the situation where traffic signals are inoperable.
