Use headlights in fog
I was driving in the dense fog not long ago. It was unbelievable how many cars didn’t use their headlights. You could hardly see a car length ahead of you. The worst part of this complaint was that a state trooper in an SUV went by without a single light turned on. I guess stupid is as stupid does. Follow the law people, or at least use common sense, and don’t do what this trooper did.
