Highways England operational staff are automatically alerted to rising traffic flows from roadside detectors. At a pre-determined threshold, operators are prompted to begin the process of opening the hard shoulder. CCTV is used to check for any stopped vehicles or obstructions in the hard shoulder. Once checked, the hard shoulder is opened to traffic by the operator implementing a speed limit sign above the hard shoulder.

The decision to close the hard shoulder is again taken based on location specific, pre-determined, traffic flow thresholds.
