In a lot of the posts regarding speeding, there is a great deal of mention about tracking history and observation. What exactly constitutes "tracking history"? Is there a procedure/guideline/timeline that needs to be followed? When an officer's notes read "...I observed a vehicle travelling at a high rate of speed...", what is the basis for the observation?
In other words, is it as simple as a car attracting attention (for pretty much any reason) being sufficient for an "observation"?
