While I would put it a little differently than GigAg04 did, I would agree with him that this is not something you should count on. For one thing, there is no state requirement that the equipment be certified as calibrated on any regular period. There is a federal requirement that the equipment broadcast on the assigned frequency, but no specified check period that I am aware of (I am not a radar technician, just an instructor). As in many cases, manufacturers give recommended maintenance periods to avoid liability on their part and help customers avoid liability. These are not enforceable by courts..30calSolution wrote:If their equipment is not up to date with the state and federal standards it will be tossed out. There's no Ifs ands or buts about it. As far as I know they have to have it checked to make sure it's calibrated correctly yearly, so if they haven't your home free. Unless you live in the state I just came from, Ohio, they can just write you that ticket because it sounded like you were speeding.gigag04 wrote:*HIGHLY* unlikely but technically possible. Also a good officer has your speed visually estimated before he confirms it with a radar/lidar. If you were speeding and choose to lie about in court to get out of the fine - you commit perjury. My conscience won't allow me to do that. I'll take my licks and move on in my life..30calSolution wrote:Also, you can question the equipment he was using and ask to see if the inspection is up to date on the calibration, if it isn't it will be thrown out due to possibly faulty equipment
And, because of the possibility of liability, it is very hard to find cities operating out of date equipment.
Overall, I would not bet on this happening and do not recommend it as a tactic. My recommendation (other than being careful about your speed) is to never dispute the speed the officer claims you were going without proof that it is physically impossible (accusing my daughter of speeding on her moped in a 45 mph zone was one example of this - lawyer from an accident did it, not a cop though). Dispute other parts of the law and you stand a much better chance of winning than arguing what speed you actually were traveling at.
