OP: Beware of those claiming to be attorneys who insist that this or that rule is the law. This is not how lawyers are trained to think & analyze situations. This is how paralegals and other non-lawyers often approach “the law”.
My point in sharing this caution is to let you know that there is no clear-cut answer to your situation. It depends upon the facts & circumstances of your situation then and now.
No well educated lawyer would ever accuse another of “misstating the law” unless that lawyer were engaged in a paralegal level of law practice involving minor traffic offenses and simple misdemeanors. (Even in these matters there are exceptions depending upon the facts & circumstances of the case.)
If simply reading a law or rule were sufficient to determine the outcome of a legal matter, there would be no need for lawyers or for law schools–just hire clerks to state the law & impose the fine or punishment. LOL
