Studies looking at snowmobile deaths in Minnesota and several other states show numbers are increasing at a steady rate, USA TODAY reports.
New preliminary studies presented this week at a meeting of the American College of Emergency Physicians in Denver suggest stepped-up safety campaigns warning riders of the dangers of combining alcohol and snowmobiling aren't doing much to reduce fatalities.
The newspaper says one study suggests alcohol is involved in 20% to 40% of fatal crashes, according to data from Michigan, Minnesota and New York.
According to the Minnesota Department of Natural Resources, there were six snowmobile deaths in the state last season. At least three of the fatalities had blood alcohol levels above the 0.08 legal limit for operating a vehicle.
