| | Some info
I wasn't aware they recorded the speed at all... I can't say for sure if they do or not but it is true that the officer's word is the proof. I've gotten several speeding tickets unfortunately and they all went more or less like this:
1.) As the hearing begins the officer makes his/her statement. They usually start with their qualifications like how many years they've been on the force and their experience with the laser/radar device. If they don't than I would certainly ask them when it's your turn. If you can make them seem inexperienced than you may get a reduction or get off. Next they usually make a statement about the device's approval by the state and recent calibration. Again, if they don't then question it. Then they usually make an account of what happened as they saw it. They state that they observed you speeding and verified it with the radar/laser gun and anything else worth noting.
2.) Next it's your turn. If you plan to fight the ticket then I would all into question as much as you can. Even if they mention everything above I would ask the officer how far away he thinks you were during his visual estimation, how long he observed you for before using the device, how far you traveled during that time... look for inconsistencies and unsure answers and point them out. Ask about what conditions the radar/laser device works and doesn't work and point out any similarities to your situation.
3.) The officer gets a chance to make more remarks based on what you've said although in my experience they usually don't
4.) You get a chance for final remarks
5.) The judge decides if you're guilty or not guilty. If your state has a traffic court DA like NY does than you may get a chance to reduce your charge through him/her. Sometimes it doesn't matter how good your case is, you're always going to be guilty but you might get lucky.
good luck and hope this helps!
