Driving records of 271 persons hospitalised for mental illness were compared with 687, 228 driving records of persons living in the same general driving environment. Three groups of patients were studied: 1- schizophrenics; 2- psychoneurotic disorders; and 3- personality disorders. Accident rates for the psychoneurotic and personality groups were statistically higher than the rate for a comparable group of King County drivers. The accident rate for the schizophrenics was comparable to the population.
