Manoeuvring

A variety of different crash types can occur when vehicles are manoeuvring. Manoeuvring includes vehicles entering or leaving the roadway, making turns other than at intersections (including ‘U' turns) and parking.

Vehicles can enter or leave the roadway for a number of reasons. These include to gain access to a roadside property (housing or commercial) or other roadside activity. This becomes a greater problem when vehicles need to cross opposing streams of traffic. Roadside activity includes vehicles stopping at roadside markets or at informal pedestrian drop-off or pick-up points. This is especially a problem at urban fringe areas where there is often higher traffic speed, but also a large number of vulnerable road users present, including pedestrians. Various road design elements can contribute to the occurrence of this crash type, including lack of turning facilities, reduced sight distance (for instance due to poor road alignment), and unregulated roadside activity.

‘U' turn crashes can occur when the U-turning vehicle is struck by a vehicle from the opposite direction or by a vehicle from the same direction. These may occur as a result of inadequate turning facilities, or lack of opportunities for turning due to high traffic volumes.

Manoeuvring crashes can also occur when vehicles either enter or leave a parked position. This can result in collisions with other vehicles, or with vulnerable road users including pedestrians, cyclists and motorcyclists. Factors leading to increased likelihood of parking related crashes include high parking demand and turnover, reduced sight distance, inadequate cyclist facilities.
