Accident proneness is a reference to the belief that some people have a predisposition for accidents. Although this is a lay concept that has very little literature behind it, it seems that some people have an unusual number of accidents. We all know someone who could be described as being a 'klutz' or accident prone. This is possibly the result of difficulty concentrating or of impulsive behavior that is indulged in without adequate regard for consequences. Some individuals also have greater problems than others with physical coordination that might also be contributing factor.
