Physically Handicapped Drivers: A Comparative Study of Driver Records

By: Dell R. Dreyer

This study was conducted at the request of California State Assemblyman John P. Quimby, who was interested in the driving record of handicapped persons with loss of, or limited control of, one or more of their limbs. This study was expected to be useful in evaluating California's driver licensing policy and in providing some guidance to insurance companies in establishing premiums for handicapped drivers. California's policy has been to license physically handicapped persons who meet the same standards on the written and on-road examinations as non-handicapped persons. The purpose of this study was to determine whether or not handicapped drivers have accident records different from those of non-handicapped drivers, and consequently, whether there is any basis for differential licensing standards or insurance premiums.
