Dark Signal, Deputy, and Orange Lines
It is 7:40 a.m. on a two-lane state highway in Louisiana. A thunderstorm knocked out power, and the signal at a four-way intersection is completely dark. A sheriff's deputy stands in the intersection directing traffic with hand signals. Orange 'Road Work Ahead' signs and a flagger are posted 300 feet past the intersection for a resurfacing project. Temporary orange lane markings divert traffic around an open manhole cover, but the old white edge line still runs straight ahead. As you approach, the deputy faces you with his right arm raised and palm toward you. Beyond the intersection, the flagger holds a 'SLOW' paddle. The posted speed limit is 55 mph, workers are visible in the closed lane, and you need to reach work by 8:00.
1. The signal is dark and the deputy's hand signal conflicts with what you would normally do. What is the correct response, and why?
Read the worked answer
Start with the default rule: A completely dark traffic signal is treated like a four-way stop. You would slow, stop, yield to traffic already in the intersection, and proceed only when it is safe.
But the officer overrides that default. A deputy directing traffic has authority over the signal and over the ordinary right-of-way rules. His raised right arm with the palm toward you means stop. You must not enter the intersection just because cross traffic appears clear or because you are in a hurry.
Practical judgment: Stop before the crosswalk or stop line, watch the deputy rather than the dark signal, and wait for a clear signal to proceed. Do not creep forward to 'test' the intersection. The flagger beyond the intersection controls the work zone separately, so after the deputy releases you, be prepared to stop again for the flagger.
2. How should you handle the temporary orange markings and the old white edge line?
Read the worked answer
The orange markings are the active traffic control in the work zone. They were placed to route traffic around the open manhole and the closed lane. The old white edge line is no longer a reliable guide because it runs straight into the work area.
Reasoning: Following the old white line could put you into the closed lane, the manhole cover, or workers. The temporary orange markings, the flagger, and any arrow signs work together. If the path is unclear, slow down and stop before the confusion point rather than straddling lanes or guessing.
Action: Follow the orange diversion, stay in the indicated lane, and obey the flagger's paddle. Do not change lanes abruptly to get back to the old line. In a work zone, temporary markings and flagger directions control over the permanent paint.
3. What speed and following distance are appropriate here, given the 55 mph limit?
Read the worked answer
55 mph is a maximum for normal conditions, not a target. You are approaching a dark signal, an officer directing traffic, a flagger, a lane shift, an open manhole, and visible workers. Any one of those requires a reduced speed; together they require a speed that lets you stop within the distance you can see and react.
Reasonable approach: Slow well below 55 mph before the intersection, cover the brake, and increase following distance so you can see the deputy and the flagger and still stop smoothly. Do not tailgate the vehicle ahead through the work zone. If a worker steps into the lane or the flagger changes the paddle, you need time to stop.
Legal point: Louisiana work-zone penalties are enhanced when workers are present. Saving a few minutes is not worth a citation or a collision. Arriving at 8:00 is less important than arriving safely.
