A ROAD WORK AHEAD sign is easy to read in daylight but barely legible during a headlight inspection. Cleaning and realigning it make no difference. An identical new sign on the same support is clearly readable from the same approach. These findings point to:
Correct answer: A - Deteriorated retroreflective material.
An inspector reviews four completed tasks before a temporary traffic shift opens. Which task must be redone?
Correct answer: C - Covered obsolete lane markings with black paint.
Traffic backs up around a curve and beyond the farthest warning sign at a freeway lane closure. Drivers encounter stopped vehicles before receiving any work-zone warning. The original sign spacing and merging taper match the approved layout. Which revision should the responsible agency prioritize?
Correct answer: C - Adapt the advance warning to reach drivers before the queue.
During resurfacing, two same-direction lanes reduce to one because the right lane closes. The selected approach speed is 35 mph, and the measured lateral offset is 10 feet. The plan uses the shortest recommended MUTCD taper, rounded up to the next 5 feet. What length should be marked out?
Correct answer: B - 205 feet
A crew selects cones for overnight utility work on a 35-mph street with streetlights. None of the cones has its own lighting device. All listed white bands are retroreflective, encircle the cones, and are correctly positioned. Which set meets the nighttime requirements?
Correct answer: B - 32-inch cones with a 6-inch upper and 4-inch lower white band.
Both lanes of a two-lane, one-way roadway shift left around a work space; neither lane ends. Warning signs and channelizers already define the approved traffic path. A supervisor proposes an arrow board to reinforce the shift. How should the technician respond?
Correct answer: A - Keep the signs and channelizers without an arrow board.
The opposing flagger radios that the one-lane section is clear. To release the waiting queue, a flagger turns the paddle to SLOW but keeps the free palm raised above shoulder level toward the drivers. The first driver hesitates. Which correction gives a consistent signal to proceed?
Correct answer: D - Hold SLOW stationary; motion forward with the free hand.
Two automated flagger assistance devices (AFADs) are proposed for a 90-minute bridge repair. At the planned operating position, one trained flagger can see both devices, but a bend blocks the view of the westbound approach. Each approach has one lane, advance warning, and adequate stopping sight distance. For that operating position, which staffing decision follows the MUTCD?
Correct answer: B - Use two trained flaggers because one approaching traffic stream is hidden.
A temporary sidewalk diversion includes a ramp with a 6% running slope. Its landing measures 54 inches by 60 inches and has a 3.5% cross-slope. The surfaces are firm and slip-resistant, and the remaining access features comply with the plan. Which measurement identifies the correction needed under MUTCD Typical Application 28?
Correct answer: C - The landing's 3.5% cross-slope
A pothole crew works along the same road for four consecutive nights. Its vehicles stop for 12 to 20 minutes at a repair, advance several hundred feet, and repeat the process. Warning devices move with the crew. The operation is classified as:
Correct answer: D - Mobile
