Has anybody in Virginia ever beaten a speeding ticket with a speedometer calibration certificate? I recently got a reckless driving ticket in Chesterfield (23 mph over) and am confident that my speedomer is off by at least 3 mph. If I get a certificate saying that my speedometer read less than I was actually going, will a judge reduce the ticket? Or is this probably a waste of my time and money? I was also debating hiring a lawyer. I haven't had a speeding ticket for 6 years and hoping the judge will drop the reckless charge. I have a CDL and really don't want to lose it.
