Legal Question in Constitutional Law in Massachusetts

Re: Commerce Clause

Not successfully. States have broad immunity from lawsuits, though many allow personal injury actions where a private entity under similar circumstances could be held liable.

Even if you can bring a lawsuit, I don't think the facts of your case would get you very far. The state may be at fault for re-routing the truck, but I don't see how it could be at fault for the traffic accident. It did not become the truck's liability insurer by re-directing it.

And, of course, all of this assumed you are right about the order violating the Commerce Clause. The usual way to violate this clause is by enacting laws which conflict with it, though I suppose specific actions can violate it as well.
