Work zones: read the path, then read the signal
For: California adults preparing for a noncommercial Class C knowledge test. This short lesson is original practice material, not an official DMV test.
Follow the temporary path
Roadwork can change which lane is open and where it travels. Follow the current work-zone signs and channelizing devices through a lane shift. Do not cross cones or drums to return to a familiar line. Keep scanning: crews, equipment, and traffic can change conditions quickly.
Give the flagger control of a shared lane
On a two-way road narrowed to one lane, traffic directions take turns. If the STOP face is directed toward you, stop before entering the controlled area and wait. Do not decide for yourself that the lane looks clear, and do not copy a vehicle that moves against the signal.
After stopping, a flagger may direct your direction to proceed using the SLOW face together with a hand motion forward. Move carefully in the indicated lane and keep watching for workers, equipment, and traffic. The paddle and gesture together communicate the action.

Questions, answers and explanations
A road-repair zone bends the usable travel path to the left. Cones and temporary work-zone signs mark that path; an older lane line remains visible straight ahead. Which path should you follow through the work area?
- Follow the path marked by the current work-zone signs and channelizing devices until the normal roadway alignment resumes. (correct): Correct. Use the current work-zone routing through the shift and continue to watch for the next sign, device, worker, or vehicle.
- Stay on the old painted line, even where that would take you between the cones.: The usual paint may no longer describe the open path during staged work. The signs and channelizing devices show the route through the work zone.
- Cross the cones early to return to the road's usual alignment as soon as possible.: Crossing the cones defeats the temporary traffic control and can put you into the closed work area. Follow the marked shift instead.
Temporary traffic-control devices show how the road is routed through the work area. Read and follow that temporary path; do not drive through the devices to get back to the familiar alignment.
California driver guidance plus general safety application; not a standalone statutory interpretation
A work crew has reduced a two-way road to one shared lane. You approach a flagger facing your vehicle with the STOP face of a hand-held paddle directed toward you. What should you do?
- Stop before entering the controlled section and wait for the flagger to release your direction. (correct): Correct. Stop and wait for the signal that releases your direction. The flagger controls the shared section while opposing traffic takes its turn.
- Proceed slowly because the other end of the shared lane appears clear.: A clear-looking lane does not tell you whether opposing traffic is still inside the controlled section. The STOP signal means wait.
- Follow the vehicle ahead into the lane because it has already started moving.: Another driver's movement does not cancel a STOP signal directed at you. Wait for the flagger's instruction.
The STOP paddle facing approaching traffic is the flagger's stop signal. In alternating one-lane control, wait for the release instruction rather than judging that the lane is clear yourself or following another driver.
California driver instruction is to obey flagger instructions; paddle procedure is official California temporary-traffic-control guidance
You have stopped at a flagger-controlled one-lane section. The flagger faces your vehicle, displays the SLOW side of the paddle, and motions with the free hand for your direction to proceed. What is the safest response to this signal?
- Proceed carefully in the directed lane, continuing to watch for workers, equipment, and vehicles. (correct): Correct. The flagger has released your direction. Proceed cautiously in the indicated lane and stay alert for people and equipment.
- Remain stopped until the flagger turns the paddle to STOP.: The flagger's described hand motion directs stopped traffic to proceed. Do not wait for a new STOP signal before moving.
- Accelerate through the section to clear it before the flagger changes the signal.: The signal permits movement, not speeding. Workers, equipment, and the changed roadway can still require careful control.
The release signal combines the SLOW face with a hand motion directing stopped traffic forward. Move through carefully and keep scanning; a proceed signal does not remove the need to control speed and watch for hazards.
