Aims: Ontario introduced an Administrative Driver's Licence Suspension (ADLS) law in 1996, whereby a person with a blood alcohol level over the legal limit of 80 mg%, or who refused to provide a breath sample, would have his or her driver's licence suspended immediately for a period of 90 days. We test the differential deterrence hypothesis which would predict that social or lighter drinkers would be more affected by the Administrative Driver's License Suspension law than heavier drinkers.
Design: Data from the 1996 and 1997 cycles of the Ontario Drug Monitor, a general population survey of Ontario adults (monthly cross-sectional surveys), were employed (response rate 64-67%).
Background: On November 29, 1996, Ontario introduced an Administrative Driver's Licence Suspension (ADLS) law, which required that anyone charged with driving with a blood alcohol concentration (BAC) over the legal limit of 80 mg% or failing to provide a breath sample would have their licence suspended for a period of 90 days at the time the charge was laid. This study evaluates the early effects of Ontario's ADLS law on alcohol-involved driver fatalities.
Methods: Interrupted time series analysis with ARIMA modelling was applied to the monthly proportion of drivers killed in Ontario with a BAC over 80 mg% for the period Jan.
