Our Company

Four Aces is an on-call 24/7 traffic control service.

Road traffic control involves directing vehicular and pedestrian traffic around a construction zone, accident or other road disruption, thus ensuring the safety of emergency response teams, construction workers and the general public.


Flagging and Lane Closures are essential parts of many work activities where workers may be exposed to danger from moving traffic. Many years ago the people directing traffic around obstructions carried red flags on short handles. From this they were called “flaggers” and this name stuck even after the rules changed and the familiar “Stop/Slow” double sided paddle was adopted. Their actual title is “Traffic Control Persons” or TCP’s.
