Three Speed Numbers in a Night Work Zone
At 9:40 p.m. you are southbound on a two-lane state route posted 55 mph, in steady rain, with a pickup holding about a one-second gap behind your bumper. You pass an orange diamond reading ROAD WORK AHEAD, then a black-on-orange sign reading SPEED LIMIT 45 with a WORK ZONE plaque beneath it, then a yellow diamond curve sign carrying a yellow 35 MPH advisory plaque. Two hundred feet later a flagger in a reflective vest holds a SLOW paddle and a line of cones pinches the lane to about eleven feet; a worker with a shovel stands roughly six feet from the travel lane. Beyond the cones a pilot car waits facing you with its headlights on. The pavement is slick enough that your wipers are on high, and the pickup closes up every time you ease off the throttle.
1. Which of the three speed numbers applies to you right now, and what legal weight does each one carry?

The 45 sign controls. Color and shape are not decoration: a black-on-orange rectangle is a regulatory speed limit posted for the work zone, so 45 mph is enforceable and replaces the permanent 55 for as long as the zone is posted. The 35 MPH plaque is yellow, which makes it advisory - the recommended speed for the curve, not a limit an officer can cite you for exceeding. Ignoring it in rain is still powerful evidence that you were driving too fast for conditions if something goes wrong. The original 55 is superseded until the zone ends. Practically, tonight the safe speed is below 45: the pavement is slick, the cones pinch the lane, and a worker is standing feet away. In Georgia, fines for moving violations are doubled in a work zone when workers are present, so the 45 is also the expensive number to exceed.
2. The flagger rotates the paddle to STOP, then a moment later waves you forward while the pilot car is still about 150 feet ahead facing you. What do you do, and why?

Obey the most recent signal from the flagger - the wave - but treat it as permission to enter the tapered lane slowly, not as permission to drive at normal speed. Move past the cones at a crawl, watch the worker on foot, and hold well back from the pilot car. The pilot car exists to lead a small convoy through the one-lane section at a controlled speed; passing it or crowding it defeats the entire arrangement and puts you head-on with whatever is coming the other way. If the flagger's signals seem contradictory, or a paddle and a hand wave conflict, slow or stop and make eye contact until the message is clear. The legal obligation underneath all of this is the basic speed rule: never drive faster than is reasonable for the conditions, regardless of what any sign permits.
3. What is the correct response to the tailgating pickup, and what should you not do?
Read the worked answer
Do not speed up to open a gap, and do not brake-check. Both convert a nuisance into a crash: accelerating raises your speed in a zone where stopping distance already exceeds what the wet pavement gives you, and a sudden brake tap at a one-second gap guarantees a rear-end collision that will be blamed on you as the lead driver. Instead, gradually reduce speed - ease off the throttle rather than stumping the brake - which increases the space ahead of you and shortens your own stopping distance. Signal early and deliberately so the pickup can read your intentions. If a safe pullout, wide shoulder, or parking lot appears, use it and let the truck go by. If the driver passes in the work zone, let them; do not race or block. Note the plate if you can do so safely.
