Construction and Work Zone Signs
Construction and Work Zone Signs
Work-zone signs are orange and warn of temporary conditions: workers, lane closures, detours, flaggers, and reduced speed. The Mississippi exam tests your ability to read these signs and to obey a flagger. Work zones can change hourly, so the signs override the normal road layout.
Core rules
- Orange means construction: Orange diamonds warn; orange rectangles give temporary regulations; orange arrows and channelizing devices direct traffic.
- Speed: A temporary speed-limit sign in a work zone is enforceable. Slow down before the first worker or lane shift, not after.
- Flagger: A flagger's STOP/SLOW paddle has the force of a sign. Stop at the paddle and wait for the signal to proceed.
- Lane shifts: Follow the arrow boards and drums. Do not change lanes inside a taper unless directed.
- Penalties: Mississippi work-zone penalties can be higher when workers are present. Treat every work zone as if workers are just out of sight.
Worked example
An orange sign reads ROAD WORK AHEAD, followed by a flagger holding a SLOW paddle and a lane closure with cones. The flagger is not waving you through; the paddle says SLOW. You should reduce speed, stay in the open lane, and be ready to stop if the flagger changes the paddle to STOP.
Traps
Do not speed up after the last cone; the work zone may not be over. Do not pass a flagger because you do not see workers. Do not ignore an orange speed sign because it is temporary. Do not tailgate through a lane shift.
