ACCIDENT AND VIOLATION EXPERIENCE AND DRIVING TESTS SCORE

ACCIDENT AND VIOLATION RATES WERE COMPARED ACCORDING TO DRIVING PERFORMANCE TEST SCORES FOR 1243 DRIVERS WITH CHRONIC MEDICAL CONDITIONS KNOWN TO THE CALIFORNIA DEPARTMENT OF MOTOR VEHICLES AND 401 DRIVERS NOT KNOWN TO HAVE ANY MEDICAL CONDITIONS. DRIVERS AGE 60 OR OLDER AVERAGED LOWER TEST SCORES THAN DID YOUNGER DRIVERS. AGE-ADJUSTED MEAN INDIVIDUAL ACCIDENT RATES PER MILLION MILES WERE 27.3 FOR DRIVERS WITH SCORES OF 70-79 PERCENT, 20.9 FOR THOSE WITH 80-89 PERCENT, AND 20.6 FOR PERSONS WITH SCORES OF 90 PERCENT OF HIGHER. DIFFERENCES IN VIOLATION RATES BETWEEN THE THREE SCORING GROUPS WERE NOT SIGNIFICANT. ONLY MINOR DIFFERENCES IN TYPES OF ACCIDENTS AND VIOLATIONS WERE OBSERVED FOR EACH SCORING GROUP. DRIVERS WITH PSYCHOSOCIAL DISORDERS SHOWED ALMOST NO CONSISTENCY BETWEEN TWO SUCCESSIVE TEST SCORES, WHEREAS A MODERATE CORRELATION BETWEEN SUCCESSIVE SCORES WAS NOTED FOR DRIVERS WITH ORGANIC MEDICAL CONDITIONS OR NO KNOWN CONDITION. ACCIDENT AND VIOLATION RATES WERE BASED ON A DRIVERS ACCIDENT AND VIOLATION RECORD FOR THREE YEARS PLUS HIS ESTIMATE OF MILES DRIVEN DURING THE TIME PERIOD. /BPR/
