In State v. Barnes , Mr. Barnes received a speeding ticket after state troopers used the time-speed-distance formula to estimate his speed at 84 mph in a 65 mph zone. Mr. Barnes claimed that his cell phone was GPS-enabled by his employer to send alerts if his vehicle was speeding, and there were no such alerts sent at the time in question.
But the GPS only gave an average speed over two minutes, and not the speed at a given point-in-time. With this fact in mind, and also considering the fact that Mr. Barnes failed to provide explanatory materials that the trial court had requested, Mr. Barnes' conviction was upheld.
As a full time traffic attorney, I do not see your Central Valley traffic citation as a minor matter. I will work hard to investigate the case and get the best possible result for you on your traffic trial.
