Well, that means its a 65 in a 55, not a 65 in a 70!
Whether he paced or used another method, and with this being a maximum speed citation with 10mph over your limit, there is not a speedometer margin of error rate that will win this for you on your own. You need to hire an attorney who maybe able to negotiate a plea bargain for a non moving violation in lieu of a higher fine. Yes, it will cost you more but then again, if you have a CDL and your livelihood depends on a record with zero points, then it is effectively costing you less in the long run!
Who's "we", and I guarantee you won't get a point on your record.
You will however, get a point and a half!
And obviously, a simple request for a TBD isn't a guarantee you won't get the points.
There is no requirement to indicate the method he used on the citation.
It doesn't. Not for 10mph over. If you were cited for 3 mph over, then yeah, you can argue that is within the known margin of error so there is doubt you were in excess. For 10mph over... You'll lose that in a heartbeat!
You mean you suspect your own speedometer is not accurate? You'll need to check that on your own, and regardless of those results, that isn't a defense that you can use; you're expected to maintain equipment in working order before you put your vehicle on the road.
You can request discovery but regardless of how he measured your speed, your only chance of prevailing here is if he fails to show up for the trial or if he doesn't submit a declaration. The chances of that happening are slim to none.
Good luck!
