Anybody familiar with the frequency that radar devices have to be calibrated?
Long story short, I got pulled over this weekend doing 63 in a 45. It wasn't until the girlfriend pointed out the date of last known calibration to me that got me thinking about this. Several of her cop friends said that in PA a state troopers radar device must be calibrated every three months. The date on my citation is 4-20-09. More than three months ago. I've tried googleing some info but havn't come across anything yet.
Anybody have any info?
