Having been on both ends of this situation, I can clearly state there are nuts all over. Cars seem to forget or maybe don't realize what 80,000 lbs of heavy metal can do. Truckers seem to forget that sometimes they don't own the highway as well. (I can count myself in this group a time or two). I don't drive trucks anymore thank god, theres not much pleasure in it anymore, but I do try to respect them and give wide berth whenever possible. Having changed some years back to working on them as opposed to driving, I might add this. If you saw on a daily basis the parts I replace or rather find missing from trucks and trailers you wouldn't want to follow trucks to closely down the highway either. Just one spring leaf of which there are many and reguarly break and fall to the highway; they weigh about 10 lbs and are a solid chunk of tempered steel. Recaps we all see them. You should see the damage it does to the truck when it slings. Best advice, keep a good safe distance and expect something to fall off. Now Im not down on trucks mind you. Most companys do there best and far more than the average auto driver to keep up their equipment up. These things just happen. Be wary...
