Construction and Work Zone Signs
Construction and work zone signs warn of temporary conditions and direct you through changed traffic patterns. Kansas practice questions test orange sign meaning, flagger signals, lane closures, detours, and temporary traffic control. Work zones can change daily, so the signs and devices in place override your memory of the normal road.
Core rules
- Orange is the color for construction, maintenance, and temporary traffic control.
- Road Work Ahead, Flagger Ahead, Lane Closed Ahead, and Detour signs warn of specific conditions; they are not optional advice.
- Channelizing devices such as cones, drums, and barricades mark the path. Do not cross them to save time.
- Flaggers direct traffic with signs and hand signals. A flagger's instruction overrides the normal right-of-way pattern.
- Temporary markings may replace or conflict with permanent lines. Follow the orange devices and temporary markings.
- Work zone speed limits apply when posted; signs may also warn of doubled fines when workers are present.
Worked example
You see an orange "LANE CLOSED AHEAD" sign and an arrow board directing traffic to the left. The right lane is ending. Check mirrors, signal, and merge left smoothly behind the arrow board rather than racing to the barricade. If a flagger holds a STOP paddle, stop even if the lane looks clear; oncoming traffic may be using the open lane.
Traps
An orange warning sign does not mean the hazard is gone once you pass it; the work area may continue for miles. Do not follow old white or yellow lines through a changed pattern. Do not pass a flagger's stop signal. Also, a detour sign may route you away from your usual path without changing your destination.
