 The forecast weather conditions during the operation should also be checked in advance since this technique should not be used in inappropriate weather conditions which might lead to poor visibility or slippery conditions.

On dual carriageways, the Mobile Carriageway Technique may be used to set up traffic management in the approach zone (see Part 1: Design, Section D6.15) and lane change zone (see Part 1: Design, Section D6.16) of a lane closure. The principle is the same as given in Section O11.3 and Plan MCC1 with the working area being the coning taper to be set up. The approach signs are set up in the traffic-free zone between the passing of the monitor vehicle and before the arrival of the closure vehicles.

The procedure is as described in the previous sections except that, at the locations of the approach signs, works vehicles are either stationed on the hard shoulder in advance of the monitor vehicle or travel with the monitor vehicle and stop off at the sign locations. As soon as the monitor vehicle passes the traffic management personnel, the off side signs can set up in a traffic-free environment.

The works vehicle setting up the 2 mile advance sign will have sufficient time to travel to the 1 mile advance sign and set this up as well in the working window. Two further works vehicles are required for setting up the signs within the lane change zone. Sufficient personnel and works vehicles should be provided to set up the taper.

{{Anchor/n|O11.23.4 The actual number of vehicles and personnel will depend on site circumstances and the experience of the personnel. Careful pre-planning is necessary to determine the resources required. {{nop}} {{center|161}}
