If you've ever traveled Ohio highways during a holiday season, you may have had to unexpectedly stop your vehicle because police had set up a roadblock. Sometimes, these DUI checkpoints can cause traffic to backup for miles. You may even have had the fleeting thought to survey your surroundings to see if there was a way to get around the roadblock without stopping. Like most Ohio motorists, you likely decided against that and stayed in line with all the other cars, waiting for your turn to talk to police.
