Flagger, Pilot Car, and a Detour Arrow
At 2:10 p.m. on a Wednesday you are southbound on a two-lane road in a Connecticut suburb. Orange signs read ROAD WORK AHEAD and ONE LANE ROAD 1,000 FT. At 500 feet a flagger in an orange vest holds a paddle: the face toward you reads SLOW. At 150 feet she rotates the paddle to STOP. A pilot car with a FOLLOW ME sign is parked facing you on the opposite shoulder, and an orange DETOUR sign with a right-pointing arrow stands at a side road 300 feet ahead. The lane closure is around a curve, and you can hear a paver but cannot see the work. A pickup behind you is closing fast.
1. The flagger rotates to STOP at 150 feet. Where and why do you stop, and what do you do about the pilot car?
Read the worked answer
Stop before the flagger, in your lane, at a point where she can see you and you can see her. Do not roll past her to the work area and do not stop at the ROAD WORK AHEAD sign 1,000 feet back. The STOP paddle is a regulatory signal from a person controlling traffic; it overrides the general expectation that you may proceed when the way looks clear. You remain stopped until she turns the paddle or gives a clear go-ahead.
The pilot car facing you is not automatically your escort. It may be waiting to lead opposing traffic through the closure, or it may be staged for a later cycle. Following it without direction could put you head-on into the work zone. Watch the flagger, not the pilot car. If she waves you forward and the pilot car pulls out ahead of you, then follow at a safe distance. The key judgment is that the flagger's current instruction is the controlling signal, and a parked pilot car is not an invitation.
2. The DETOUR arrow points right, but the flagger later waves you straight ahead. Which instruction controls, and why?
Read the worked answer
The flagger controls. Temporary traffic control is a live system, and the flagger is the most specific and current instruction on the scene. The DETOUR sign may apply to a different movement, a different phase of the work, or through traffic that is being routed away from the closure while local access continues straight. It may also have been placed for an earlier configuration and not yet covered.
A driver should not turn right merely because an orange arrow points that way when a flagger is actively directing traffic straight. The flagger can see the work zone and knows whether the lane is ready. If you turn against the flagger's direction, you may enter a closed lane or conflict with construction equipment. The correct response is to follow the flagger's hand signal, proceed slowly, and stay alert for changed conditions around the curve. The exam is testing the hierarchy: a person directing traffic outranks a static detour sign when the two appear to conflict.
3. What should you do about the tailgating pickup as you slow for the flagger?
Read the worked answer
Slow early and progressively rather than braking abruptly at the last moment. Tap the brake pedal a few times to illuminate the brake lights before you actually need to slow, and leave extra space ahead so you have room to stop without slamming the brakes. Do not speed up to satisfy the tailgater; the flagger's STOP paddle is mandatory, and a rear-end crash is more likely if you make a sudden, late stop.
If the pickup remains close, keep your speed reduction smooth and use the space ahead as a buffer. Do not wave the driver around or encourage a pass into a work zone. The flagger may need to hold both directions while equipment moves, so the wait could be longer than the tailgater expects. Your obligation is to stop safely and predictably. The judgment point is that work zone speed control is not just about your own stop; it is about communicating the stop to drivers behind you so the queue forms without a collision.
