Dag man, you have the RIGHT to demand to see his equipment at the time of the ticket. If he can't PROVE to you (i.e., show you his machine and it recorded the speed) then you're free & clear. Hate that you didn't know that though 🙁
BTW, I got a 19 over, and I just used my "Prayer for Judgement", paid the lawyer $125 to show in court for me and tell the judge I wanted to use that, and POOF, no record, no driving class, nothing. But I can't do it again for 3 years from the court date or else it'll come back on my record.
