How about talking to your own lawyer? Who do you think is going to fight for you if you do get a ticket?
Seriously, Only a lawyer carried malpractice insurance to cover him when he is sued for giving his client the wrong advice! DON'T get your legal advice from cops and bureaucrats! All they may know is what is written in a book. They don't know case law, they don't understand rules of construction, and they don't understand the Constitutional burden of proof.
You have received the correct answer here already. Laws are written to give NOTICE to the public of what is a PROHIBITED ACT! If it is not prohibited, it is legal for you to do. without that NOTICE in writing, you cannot be prosecuted for a mythical offense.
I went around with the Illinois DNR staff on a similar issue about 20 years ago, and even I could not get their in-house counsel to call me back! I did find out that they had some NAZI teaching at the State Police Academy telling officers that if its not written as being permitted, it was FORBIDDEN! When an officers shared that gem with me, I asked him where in the Constitution did it say that? I got the thousand mile stare.
Look, I don't like to disparage members of Law Enforcement. They do a good job for all of us, in the main. But, they are not lawyers. I have consulted with officers, and advised them privately about the interpretation of new regulations for more than 30 years. They complain that when they have a legal question, and take it up the command structure in their department, as per their own rules, they never get an answer. The Department's lawyers, ( mostly city attorneys, but also County Prosecutors, or State Attorneys General, as appropriate) never meet with the lawyers, never are available to ask questions to, and generally just don't exist until you meet them in court. I have taken many officers out for coffee after their cases were dismissed against my client to answer their questions, and tell them what they did wrong. I got that advice to do this kind of thing from a senior member of the bar when I first started out, and he was respected by all the officers, even more so when he beat them in court. I have had officers attend my hunter safety courses with their own kids, and were thrilled to learn what the game code really means from someone who is actually suppose to know( me!). I made many good friends with deputies and officers from those contacts. And I have gotten referrals to other officers who have called me with questions. They are always surprised that I don't want money from them for helping them do their jobs better. And, yes, I have had talks with prosecutors and city attorneys about doing a better job of advising their officers, without much effect.
