Actually what really happened was. So you admitted you reached down to secure your cell phone, so you failed to devote your full attention to driving and since you were bent down to secure that phone, you have n o clue how fast you were traveling. You were the third vehicle in line, the officer can not see the license plate on a vehicle from 2200 feet away. which is where you were locked in at. You were gaining on the two other vehicles that were in front of you. Your speed odometer is not calibrated as well so there is that. The reason the officer did not turn the overhead emergency lights on immediately is because there were other vehicles on the roadway that he had to yield to or there would have been a collision. Where you were stopped has nothing to do with where the violation occurred. The officer wears a body camera that was reviewed and the officer stated that you were stopped for 50 mph in a 35 mph residential area where children play. So I would gets the facts straight, have knowledge of how a radar works and knowledge. If a child or a vehicle would have pulled out in front of you at the speed you were traveling it would have ended bad. So obey the speed limits that posted and you will be ok.
