Not restricted there Rob but it can run but I believe you've mistaken it's potency a bit. You really gotta use 2x or higher rates for all that killing. I use Polaris and gly on my fence rows they stay clean but I spray under oaks and they're fine. But I use it according to label. But in abused situations it could be dicey. And oh yea the online RUP test is a joke just like the old paper test was. No problem passing it with little to no study.
