Traffic Control Directory

Traffic control is a safety trade — a poorly run lane closure or an uncertified flagger puts workers and drivers at risk, and the contractor who hired them inherits that liability. We evaluate traffic-control companies on certification and insurance, the quality of reviews around showing up on time with the right equipment, written scopes for each job, and the operational consistency that separates a real local crew from a labour broker with radios.

✕Reviews citing no-shows, late arrivals, or untrained flaggers
✕A generic name with no local base or dispatch
✕Reluctance to put crew qualifications in writing
