Work zone sign · MUTCD W20-1
Road Work Ahead
Road construction or maintenance work is ahead. Conditions may change suddenly, with workers, machinery and lane changes.
- Shape
- Orange rectangle (sometimes a diamond)
- Color
- Orange background, black letters and border
What to do
Slow down, stay alert and be ready to slow down or stop. Watch for workers, equipment and signs directing you into other lanes, and obey posted work zone speed limits.
Where you see it
Placed on the roadside well before the work area begins.
Test trap
Do not wait to slow down until you see the workers; the sign is an early warning. Orange signs mean a temporary condition, so yellow-sign habits (speed, lanes) may not apply.
Memory tip: Orange = temporary work. Slow down before you see anyone.
Practice question

- A school zone is ahead
