Single-vehicle collision in the autumn of 2010

A single vehicle collision or single-vehicle accident is, as the name implies, a type of road traffic collision in which only one vehicle is involved.[1] Included in this category are run-off-road collisions, collisions with fallen rocks or debris in the road, rollover crashes within the roadway, and collisions with animals.

The term single-vehicle collision is not generally used unless the rider/driver and passengers of the vehicle are the only ones injured. Although in some cases innocent bystanders (e.g. pedestrians or bicyclists) can also be hurt or killed, the term single-vehicle collision is unlikely to be used to describe such collisions.

The normal inference is that the cause is operator error. Common factors contributing to single-vehicle collisions include excessive speed, driver fatigue[2] and alcohol.[3] Environmental and roadway factors can also contribute to single vehicle crashes. These include inclement weather, poor drainage, narrow lanes and shoulders, insufficient curve banking and sharp curves.[4] Some vehicles have unpredictable car handling characteristics and/or defects, which can increase the potential for a single-vehicle collision.

Suicide is also sometimes cited as a possible cause of single-vehicle accidents, although this is difficult to determine.[5][6]
