Mothers Against Drunk Driving (MADD) has launched a new public awareness campaign aimed at Canadian Justice Minister Irwin Cotler. "Enough is Enough" advocates dropping the Criminal Code's blood alcohol concentration (BAC) limit from 0.08 to 0.05 percent, to "protect innocent drivers on our roads. "MADD Canada CEO Andrew Murie thinks that lowering the BAC limit could result in a 6-to-18 percent reduction in crash deaths. But questions have been raised about the science behind that campaign.
MADD selectively cites a report published in 2002 by Robert Mann of the Mental Health Centre. Mann, in turn, had got those numbers from two separate studies whose data was selected from Sweden and Australia. The conclusions in Mann's report seem to ignore the Swedish authors' numerous warnings and cautions, as well as the limitations in the Australian study. First, the Australian study examined the effectiveness of breath testing, not lowered BAC levels, on fatal traffic crashes. Also, that research was started in 1976 when "liquid lunches" were far more common. What's more, the Australian data varied: whereas the state of Queensland saw the 18 percent decline in fatal accidents cited by MADD's Murie, in neighboring New South Wales, fatal accidents decreased just 8 percent.
It is also reported by the Ontario Community Council that the majority of drivers in alcohol-related fatal crashes are repeat offenders with BACs over 0.15 percent—meaning that the problem is drivers who repeatedly get behind the wheel with BAC levels twice the legal limit, not social drinkers who consume a glass of wine or two. This makes MADD's concern seem wasteful, given the downward trend in alcohol-related traffic deaths.
The Canada Safety Council, the Canadian Council of Motor Transport Administrators and the Traffic Injury Research Foundation take issue with MADD's campaign. Even the Ontario Community Council has determined that lowering the BAC would mean more work for police and the courts. But to MADD's Murie, the math question is simple: "If you lower BAC limits, regardless to what level, you'll save Canadian lives. "Unfortunately, the math doesn't quite add up.
