I know we consider our vehicles package "cars", but I think the rest of the world refers to them as trucks. When there are different speed limits posted for cars and trucks on the freeway, which one are we suppose to follow? Usually the truck speed limit will be 10mph less than the car speed limit. I have always followed the truck limit as don't want to risk a ticket, but I'm also usually driving one of the larger single unit box-trucks. What do you guys think?
