Work Zone & TTC Signs (TTC, G20, W20 Series)
Temporary Traffic Control (TTC) and Work Zone signs are essential for guiding traffic safely through construction and maintenance zones. Engineered to exceed WSDOT and FHWA MUTCD safety standards, these signs use high-visibility fluorescent orange 3M™ High Intensity Prismatic or Diamond Grade reflective sheeting on rigid aluminum substrates, providing critical advance warning and protecting both your flagging crews and the traveling public.
