Where to begin... It's about 99.9% probable that the deputy was using a laser. On the interstate, a radar would be no good due to all of the traffic. As mentioned earlier, a deputy can get a reading from almost a mile away. The deputy puts the dot on the car he wishes to get a reading from a presses the trigger. The reading comes back almost instantly. The only thing I can think of is that there might have been another vehicle nearby that looked the same as yours and the officer pulled you over instead of him. Radars in baseball games operate on a different band that police radars. In this case, the deputy was more than likely using laser aka lidar which is 100% different than baseball. Cops don't calibrate the speed equipment. They check the calibration before and after any citation is issued. The officer/deputy/trooper has no obligation to show you the laser or radar reading. Yeah, if you have Illinois or Florida plates, never believe anything the officer says. http://forum.brewerfan.net/images/smilies/eyes.gif In order for the radar to be in properly working order, it must be within 1 MPH of a known speed. Cops carry calibrated tuning forks in their squads that is used to check the calibration. If the reading is more than 1 MPH off, the radar cannot be used. It's easiest to get a reading off a front license plate, but an officer can still get a reading off the front grill, bumper, etc. Who told you this steaming pile of misinformation? It's a 4 point violation at 11-15 over. It's a 3 point violation at 1-10 over. EDIT: The dollar amount between 10 over and 15 over is exactly the same. Not what I call a big difference. Just think, if the officer would have lied and said you were doing 85, he would have won an MP3 Player from his police department because of his quota. Those 20+ MPH over speeding cites are worth so much more than those 15 MPH over ones. http://forum.brewerfan.net/images/smilies/eyes.gif By the way, ticket quotas are illegal in Wisconsin. Do you have a front license plate? The officer saw it as he passed, ran it on his computer, and it came back expired. If you want to contest the citation, go ahead. It's everyone's right. The truth is that police and the prosecution will do their best to avoid going to trial. If you really want to contest the citation, read the back of the citation. It will tell you how to contest it. Once you plead not guilty, you will hear from the city/county's attorney. Chances are you will set up a pre-trial conference. That's where the game begins. See if the prosecution will allow your citation to be amended to a lower speed or to an equipment violation like faulty spedometer. If you do go all the way and fight the citation with a trial and lose, expect no mercy from the judge.
