What federal law requires that semi-tractor personal injury civil cases be filed in federal courts?What is the Federal Rule, and where to research the law
I do not know what they answer to your question is, at least not for certain. However, I have some ideas as to what you might look for and where you might look.
Because they are involved to such a great extent in interstate commerce (which cannot be regulated by the states) large trucks fall under federal regulations. There are a lot of rules about driver qualifications, hours that drivers may work, etc. I would imagine that these regulations are why injury cases involving such trucks must be filed in federal court.
Hopefully, the link below will give you a starting point from which to look for the rule you are asking about.
