A survey crew sign is the orange diamond warning that flags a surveying party working on or near the roadway, defined in MUTCD Part 6 as the Survey Crew sign (W21-6). It's placed in the advance warning area so drivers see it before the crew and can slow down or move over, not spot the surveyors at the last second.
The different types of survey crew signs cover the whole approach and the work point. Survey Crew Ahead and Survey Party Ahead give advance warning; the Survey Crew (W21-6) and Surveyor Symbol mark the operation; and cone collars add a warning right at the cones by the crew.
Both are orange diamond work-zone warnings, but they say different things. Road Work Ahead flags a fixed construction zone; a Survey Crew sign specifically warns of a surveying party, which is usually brief and mobile. The right sign tells drivers exactly what — and who — is on the road ahead.
On a high-speed highway, put the first warning farther back — around 500 feet or more ahead of the crew — and use larger, higher-reflective signs (up to 48" x 48") so drivers read them in time at speed. Add cones, drums, or delineators to channel traffic away from the crew, and keep the setup on the shoulder side wherever possible.
Signs warn; channelizing devices create space around the crew. Pair your signs with orange traffic cones, barrels and drums, and reflective delineators, and slip survey crew cone collars over the cones so the warning is right where the surveyors are working.
Yes — and because survey work moves, portable is the norm. Roll-up Survey Crew signs mount on roll-up sign stands and deploy in seconds; ConeBoss signs drop onto a cone, and cone collars wrap one. Rigid aluminum covers a longer or fixed setup.
