Night Lane Shift Where Old and New Markings Disagree
At 11:40 p.m. on a Thursday you are northbound on I-95 approaching a resurfacing project. Two right lanes are closed. An arrow board on a trailer directs traffic to the left, but the pavement beneath it still shows the old white dashed lines curving right, while new temporary yellow lines and raised pavement markers run straight. An orange "SPEED LIMIT 55" sign stands beside the road; the permanent white sign 300 feet behind you reads 65. A "FINES DOUBLE IN WORK ZONE" plaque is mounted below the orange sign. No workers are visible, equipment is parked, and the right shoulder drops off about 3 inches where milling has started. Your GPS says to keep right for the exit in half a mile.
1. The old white dashes and the new temporary markings point different ways. Which governs, and what do you do about the exit your GPS is directing you toward?

The temporary traffic control configuration governs. Work zone markings, arrow boards, and channelizing devices are the current, deliberate instruction; the old white dashes are remnants of the pre-work layout and may lead directly into a closed lane or off the milled edge. Hierarchy to apply: a uniformed flagger or officer first, then the arrow board and temporary markings, then the permanent markings. The GPS knows nothing about tonight's closure, so ignore it and follow the posted layout. As for the exit in half a mile, assume it may be inside the closure until a sign tells you otherwise; do not cut right across the taper to make it. If you miss it, take the next exit and reroute. Cutting back toward old markings at 55 mph, at night, next to a 3-inch milled drop-off, is exactly how work zone crashes happen.
2. No workers are present at midnight. Is the orange 55 mph sign enforceable, and how does the "FINES DOUBLE" plaque affect the answer?
Read the worked answer
It depends on the sign's legend, which is why you must read the whole assembly rather than just the number. If the orange sign reads "SPEED LIMIT 55" with no condition plate, the 55 applies whenever the sign is posted, workers present or not - a regulatory speed limit does not lapse at night. If it carries a "WHEN WORKERS PRESENT" plate, then with no workers on site the permanent 65 mph limit governs. The "FINES DOUBLE IN WORK ZONE" plaque does not create a speed limit; it enhances the penalty for violating whatever limit is in effect, so it changes the consequence, not the threshold. The practical judgment for a driver: you cannot audit whether the sign was properly placed under the traffic control plan, and litigating that at the roadside is not an option, so comply. Slow to 55, which is also the safe choice given the lane shift and the milled edge.
3. What specific hazards does the 3-inch shoulder drop-off create, and how should you handle it if traffic forces you toward it?
Read the worked answer
A 3-inch vertical edge is enough to catch a tire, especially a smaller or underinflated one, and can pull the car sharply right or damage a wheel and tire - and at night it is nearly invisible until your headlights are on it. If traffic squeezes you toward the edge, do not straddle the drop-off with two wheels on either side; that gives you the worst of both surfaces and unpredictable grip. Instead, slow down, hold your lane position within the temporary markings, and let the merging traffic sort itself out rather than swerving. If you do drop a wheel off, do not wrench the wheel back abruptly at speed; ease off the accelerator, let the car slow, and steer back up with a gentle angle once the tire can climb the edge. Keep in mind equipment may be parked just beyond the drop-off, and reflective clothing or a flagger can appear without much warning even at midnight.
