STAY BACK 200 Feet!
Not responsible for windshield damage!
I've seen this posted on the back of numerous industrial vehicles (dumptrucks, cement trucks, etc). While I certainly don't make a habbit out of tailgating these monstrosities, I typically laugh a little inside when I read these warnings. Do they really think that such a warning would really exhonerate them of damages that would result from their rig shedding material/cargo? I would think not.
Correct me if I'm wrong.
By the way: this is not about whether or not it's okay to tailgate. Only an idiot would tailgate these vehicles. I'm just talking about whether or not the law would hold the owner liable for damages that resulted from "discharged" cargo (rocks, wood, cement, etc).
