Construction & Temporary Signs
Detour Route Marker Sign
A marked detour takes traffic along an alternative route.
What to Do
Follow the matching detour markers until the route rejoins the normal road.
A Detail to Remember
The D-1 example is a route identifier. Use the same identifier at later junctions to stay on the intended detour.
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.
