Especially don’t courtesy wave if the light is green and a log truck is behind you. Being SC, everyone was in the left lane, while I was in the right lane traveling towards the intersection, when I come around the logging truck to an 18 wheeler pulling across my lane. I’m just glad I was in a work truck.
So next time you complain that modern trucks are too tall, join them or suck it up, because it saved my life. Eighteen wheelers aren’t going anywhere, and they certainly aren’t paying attention.
