Based on a 1993 survey of Ontario students in grades 7, 9, 11, and 13, data from students who reported driving within one hour of drinking two or more drinks are cluster analyzed. A 3-cluster typology was derived: “Marginals” consist of the lowest proportion of males, lowest delinquency, alcohol use, accident involvement, drinking-driving frequency and consequence experience; “Heavy Drinkers” consist of the greatest proportion of males, heaviest alcohol use, greatest driving exposure, highest drinking-driving frequency, few drinking-driving convictions and no drinking-driving accidents; and “Delinquents” consist of the highest delinquency, accident involvement, drinking-driving accident and conviction, and least driving exposure.
