Maybe I'm biased, but I think class 5 has the hardest time passing slower cars. We are fast, but we are small and light, so people aren't that scared of us. You see a 4000# truck coming up on you fast, everybody moves over, but some people in larger slow vehicles just don't want to pull over even when we're right on them. We need everything we can to help this, and that's why we've been running front lights for years. It seems like common sense to me, I don't know why anybody would not run lights in the day, but most people don't run them. Some good teams don't run them. There must be something I'm not thinking of.
