Its the manufactures way of saying, you get into an accident and that sucker shatters, they are not responsible for the damage it does. Most aftermarket kits, hoods etc are "offroad" use meaning they are not tested to comply with DOT specs. Everyone does it, so its not really an issue, but needs to be stated to cover their 'ass'ets
