Flagger, Pilot Car, and a Temporary 45 MPH Limit
You are westbound on a two-lane rural highway at 3:10 p.m. An orange sign reads 'ROAD WORK 1/2 MILE' and a second reads 'ONE LANE ROAD AHEAD.' Beyond them, a temporary speed sign shows '45' even though the permanent limit is 55. A flagger stands near the centerline holding a paddle toward you. The paddle face reads SLOW. Pickup trucks and a log truck are queued in the opposite direction, and a pilot car with a 'FOLLOW ME' sign waits about 200 feet past the flagger. Your lane has a solid yellow line on the left and a white edge line on the right. Rain has just started; pavement is wet, and the flagger is wearing a retroreflective vest but no hard hat. You are towing a light utility trailer. The pilot car begins moving toward you, then stops.
1. What does the SLOW paddle require, and how should you adjust speed and position before reaching the flagger?

The SLOW paddle is not a stop command. It directs you to continue at a reduced, controlled speed and to be ready to stop. Treat the flagger's instruction as controlling over the permanent 55 mph sign, and obey the temporary 45 mph posting as an upper limit - not a target. With wet pavement, a trailer, and queued opposing traffic, reduce well below 45, keep a steady lane position, and do not pass the queue or cross the centerline. The solid yellow line on your left and white edge line on your right frame your lane; do not use the shoulder to improve sight distance. Watch the flagger's hands and the pilot car, because the paddle can change to STOP. If the flagger's intent becomes unclear, slow further and stop before the flagger rather than guessing. The key is that SLOW means controlled progress, not permission to maintain normal work-zone speed.
2. The pilot car stops facing you. Should you follow it, wait, or proceed past it? Explain using work-zone control logic.

Wait. A pilot car facing you is normally escorting traffic in the opposite direction, so following it would put you head-on into the closed lane. The flagger, not the pilot car, controls your entry into the one-lane section. Stay stopped before the flagger's position, keep your wheels straight, and watch for a hand signal or a changed paddle. Do not creep past the flagger to get a better look - that closes the gap the flagger needs and can block the pilot car's turn. If the flagger waves you forward, proceed only after confirming the pilot car has cleared your lane and the oncoming queue is held. If no signal comes and the flagger turns away, wait; a flagger's attention elsewhere is not an invitation. The presence of a FOLLOW ME sign does not mean follow any pilot car you see; follow the one assigned to your direction after the flagger releases you.
3. A temporary sign later says 'END ROAD WORK' but orange cones remain for 300 feet. What is the safest interpretation?
Read the worked answer
The END ROAD WORK sign ends the active work zone, but it does not erase every hazard. Cones, equipment, and a wet shoulder can remain for several hundred feet, and workers may still be wrapping up. Resume the permanent 55 mph limit only after you have passed the sign and confirmed the roadway is clear; accelerate gradually, especially with a trailer on wet pavement. If a worker, flagger, or temporary device still directs traffic, that direction controls over the end sign. Do not treat the sign as permission to pass immediately or to ignore remaining orange devices. The safe reading is: the project's formal traffic control is ending, but your duty to drive at a speed reasonable for conditions continues. Check mirrors before speeding up because the vehicle behind may still be closing.
