Using a Flagger? Then its not Short Duration

Recently I have been receiving calls regarding short duration work zones and flagging operations. The crux of the calls deal with the Short Duration “exemption” regarding amount of traffic control devices, signs, etc when using a flagger for a short duration.  

The answer to this is simple in Washington State. IF YOU USE A FLAGGER FOR EVEN 1 SECOND – YOU MUST HAVE A FULL TRAFFIC CONTROL SET UP.  So you better at least of 3 signs for each approach (4 if speed is 45 mph or greater).  

Once more - If you are using flaggers, you cannot use the short duration exemption in Washington State, DOSH outweighs the MUTCD.  If you want more info check out WRD 27.20.
