Today was the second time I saw a guy who was obviously under the influence. He was swerving in and out of lanes for nearly 2 miles. It was dangerous and scary. There were no police cars in sight. In that situation, do you dial 911 and give them the plate number? I know this might sound naive but is 911 for those purposes? I was honestly afraid this person was going to hit someone else and hurt that person as opposed to getting this person in trouble. What do you do in that situation? The first time I saw something this blatant was on the highway 4 years ago.
