AN INVESTIGATION OF 1508 OF THE 1577 FATAL AND INJURY PRODUCING MOTORCYCLE ACCIDENTS REPORTED TO VICTORIA POLICE DURING 1974 REVEALED THAT ALCOHOL USAGE WAS A SIGNIFICANT FACTOR. A SIMILAR RESULT WAS INDICATED BY FIVE OTHER AUSTRALIAN STUDIES WHICH REPORT ON POST-MORTEM EXAMINATIONS OF FATALLY INJURED MOTORCYCLE RIDERS. ALCOHOL AFFECTED RIDERS WERE SIGNIFICANTLY OVER REPRESENTED IN FATAL AND SINGLE VEHICLE ACCIDENTS. THE MAJORITY OF KILLED RIDERS HAD BLOOD ALCOHOL LEVELS TYPICAL OF PROBLEM DRINKERS. MOTORCYCLE RIDERS HAD SIMILAR BLOOD ALCOHOL LEVELS TO A COMPARABLE GROUP OF DRINKING CAR DRIVERS BUT A SIGNIFICANTLY LOWER PROPORTION OF KILLED MOTORCYCLE RIDERS WERE AFFECTED BY ALCOHOL THAN KILLED CAR DRIVERS. MOTORCYCLE RIDERS AFFECTED BY ALCOHOL WERE MAINLY YOUNGER THAN TWENTY-FIVE YEARS OF AGE, BUT THIS WAS PROBABLY DUE TO THE YOUTHFULNESS OF THE MOTORCYCLE RIDING POPULATION.(Author/publisher).
