448 accidents involving quad bikes in Bavaria from the years 2009 to 2012 were analyzed in this study.
It was revealed that the risk of a quad-bike accident involving personal injury is over twice as high as that of a car accident involving personal injury given the same number of vehicles and kilometers driven. This risk of being killed or seriously injured in a quad-bike accident is ten times greater than in a car accident.
The accident analyses show typical accident patterns that can, to a certain extent, be attributed to the technical peculiarities of this vehicle type. The crash test conducted reproduced a typical set of accident circumstances for quad bike accidents: leaving the carriageway in a bend followed by a collision with a line of trees next to the road.
