With the Super Bowl this weekend, there's a major effort by Oregon law enforcement to crack down on impaired drivers. At a kickoff event yesterday, volunteer drinkers were tested by police officers, who demonstrated the effects of alcohol on driving. It was part of the "fans don't let fans drive drunk campaign." It's supported by the National Football League and several other organizations including Mothers Against Drunk Driving. In addition to New Year's Eve, Super Bowl Sunday has become a dangerous day on the road. If you're going to party, have that designated driver.
