Construction & Temporary Signs
Flashing Arrow Board Sign
An illuminated arrow directs vehicles around roadwork or a closed lane.
What to Do
Follow the displayed direction and merge with care.
A Detail to Remember
The lit arrow can be seen at a distance, giving drivers time to prepare before reaching the closure.
Understanding Construction & Temporary Signs
Work zones can change the route, road surface and available lanes. Read the sequence of signs together and watch for traffic control people, workers and equipment beyond the first warning.
