Work Zone and Temporary Traffic Control Signs

Work Zone and Temporary Traffic Control Signs cover orange signs, channelizing devices, flaggers, and temporary rules. Montana's test checks whether you can read a work zone sequence, obey a flagger, and adjust speed and lane position without endangering workers or other drivers.

Core rules

  • Orange diamonds warn of road work, lane closures, detours, and temporary conditions. Orange is reserved for temporary traffic control.
  • Channelizing devices include cones, drums, barricades, and arrow boards. They show the temporary path. Do not cross them or drive through a closed lane to gain position.
  • A flagger has the same authority as a sign or signal. Follow the paddle: SLOW means slow down; STOP means stop and wait. Do not pass the flagger until directed.
  • Temporary speed limits are posted for the work zone. Montana doubles fines for moving violations in a work zone when workers are present, so a speeding ticket can cost much more than the posted number suggests.
  • Merge early when a lane closure sign gives distance. A late merge can cause a sudden stop and a rear-end crash.
  • Work zone signs may remain when no workers are visible. Obey them until the end-work-zone sign or the permanent limit resumes.

Worked example

You see 'ROAD WORK AHEAD,' then 'RIGHT LANE CLOSED 1 MILE,' then a flagger holding a SLOW paddle. Reasoning: the first sign warns you to reduce speed; the second tells you which lane will close and gives you a mile to merge; the flagger controls the remaining lane. Signal, merge into the left lane when safe, and follow the flagger's direction. Do not wait until the cones to merge, and do not speed up after passing the flagger if workers and equipment are still present.

Traps

Ignoring a flagger is a major error. Speeding in a work zone is doubly costly. Do not assume the road is normal because you see no workers; equipment and narrowed lanes remain hazards. Do not cross a solid line of cones or drive on the shoulder to bypass a queue. Do not tailgate through a work zone.
