ACCIDENT AND VIOLATION RATES OF WASHINGTON DRIVERS WITH MEDICAL LICENSING AND DRIVING RESTRICTIONS

A SUMMARY IS PRESENTED OF THE DRIVING EXPERIENCE OF THE 39,242 WASHINGTON MOTORISTS WHOSE DRIVING PRIVILEGES ARE RESTRICTED BECAUSE OF CERTAIN PHYSICAL, MEDICAL, OR MENTAL CONDITIONS. THE RECORDS OF THESE PERSONS ARE COMPARED WITH THE DRIVING OF ALL WASHINGTON MOTORISTS. THE MOTORIST WHOSE LICENSES BEAR MEDICAL DRIVING AND LICENSE RESTRICTIONS WERE GROUPED INTO THE FOLLOWING EIGHT CATEGORIES BASED UPON THE NATURE OF THEIR CONDITIONS: VISION DETERIORATION, HEART DISEASE, DIABETES, EPILEPSY, FAINTING, OTHER CONDITIONS, AND MEDICAL DRIVING RESTRICTIONS. VIOLATION AND ACCIDENT RATES BY AGE AND SEX FOR EACH OF THESE EIGHT RESTRICTION CATEGORIES WERE DETERMINED AND THEN COMPARED WITH THE CORRESPONDING RATES FOR ALL WASHINGTON MOTORISTS. PERSONS WITH HEART DISEASE AND VISION DETERIORATION PROVE TO HAVE ACCIDENT AND VIOLATION RATES ABOUT EQUAL TO THE TOTAL OF ALL WASHINGTON DRIVERS. STATISTICALLY HIGHER ACCIDENT RATES WERE FOUND FOR PERSONS WHOSE LICENSES WERE RESTRICTED BECAUSE OF DIABETES, EPILEPSY, FAINTING, AND OTHER CONDITIONS. THE VIOLATION RATES FOR THESE FOUR GROUPS WERE NOT STATISTICALLY DIFFERENT FROM ALL WASHINGTON DRIVERS. ACCIDENT RATES FOR MALES ARE SIGNIFICANTLY LOWER THAN CORRESPONDING RATES FOR THE UNIVERSAL MALE DRIVER, WHILE THOSE FOR FEMALES ARE SIGNIFICANTLY HIGHER THAN THOSE OF THE TOTAL FEMALE POPULATION. FEMALES IN THE 36 TO 50 AGE GROUP HAVE AN ACCIDENT RATE THREE TIMES THAT OF MALES IN THE SAME AGE GROUP WITH A SIMILAR RESTRICTION. VIOLATION RATES ARE NOT STATISTICALLY DIFFERENT FOR EITHER GROUP.
