The compliance rules, cited to primary law, for crews that set up work zones, close lanes, and dig in the public right-of-way. Pick your state, then the job you are doing.
If your crew works on or beside a roadway, you carry the liability for how the work zone is set up: the advance-warning signs, the taper, the channelizing devices, and the flaggers. Getting it wrong risks OSHA citations, DOT fines, voided insurance, and injury claims. This hub maps the jobs your crews actually do to the exact requirements that govern them, state by state, each backed by a verbatim quote from the MUTCD, OSHA, or your state code.
The jobs you're liable for
Set your state, then open a job to see its cited requirements.
Close a lane (work zone)
Set up a work zone: advance warning, tapers, buffer space, channelizing devices, and when a PE-stamped plan is required (MUTCD Part 6).
Flagging operation
When a flagger is required, certification, STOP/SLOW paddles, and safe positioning (MUTCD 6E).
Close a sidewalk
Temporary accessible pedestrian route, detectable barriers, and channelizer height (MUTCD 6D and ADA).
Utility lane / road work
Short-duration and mobile operations for gas, electric, water, and sewer crews.
