Detour Signs
Route and trailblazer signs that direct traffic around a closure along an approved detour path.
Detour signs guide road users around a closure and along an approved alternate route, then back to the original road. A complete detour is signed continuously — from the advance warning (DETOUR AHEAD), through every decision point with directional DETOUR markers, to an END DETOUR where traffic rejoins the route.

What makes a detour 'complete' on a TCP?
A complete detour is signed from the advance warning through every turn and decision point and includes an END DETOUR where traffic rejoins the original route. Reviewers look for continuity — no unsigned turns and a clear return to the route.
How is a pedestrian detour different from a vehicle detour?
A pedestrian detour (M4-9b) routes people on foot around closed sidewalks or crosswalks along an accessible path. It must maintain ADA-compliant access and is shown with R9-series sidewalk-closure signs and barricades.
What color are detour signs in a California work zone?
In the temporary traffic control context, detour route markers use a fluorescent orange background with a black legend and arrow, matching the surrounding work-zone signs.
