A 3-minute lesson from the Delaware course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Guide and information signs help you find your way and services. Work zones are different: lanes shift, workers are close by and speeding fines double. Orange signs and devices mean construction or maintenance ahead.

Circular flashing beacons may supplement signs. Yellow beacons go with warning and speed limit signs; red beacons go with Stop and Do Not Enter signs. Either color flashes about once per second.
An area along a highway where construction, maintenance or utility work is happening. It may be stationary (a bridge being widened) or mobile (pavement striping or patching).
Work zone signs and devices start before the work area and continue beyond it. Work zone warning signs are usually orange; most are diamond-shaped and a few are rectangular.
Barricades, drums, cones and tubular markers guide you through; at night they often have flashing or steady-burn lights. Flashing arrow panels guide you into lanes and warn that part of the road ahead is closed.
Flagger signals: stop traffic, and proceed with caution
Put it into practice
A flagger ahead of a lane closure holds up the STOP paddle. You stop and wait. When the paddle turns to SLOW, proceed carefully through the work zone at a reduced speed.
