Visual observation tracking history: Before an officer can use lidar or radar, they're (theoretically) required to visually observe traffic to pick out someone who is speeding. Police officers are trained in determining the approximate speed of a vehicle by visual observation. Once they have an estimate that a vehicle is speeding, they can then activate the lidar or radar. Keep in mind, most devices have sight-scopes so the officer can be looking through the scope to take the observation. (What this looks like to a casual observer is that the officer is just pointing and shooting at every car that comes along.) But the essential elements are:
- Device tested before and after the stop (it doesn't have to be immediately before and after, it can be several hours before and several hours after)
- Officer visually observed vehicle speeding (tracking history)
- Officer confirmed visual observation with speed measuring device or by pacing
- Officer stopped vehicle without losing sight to the point where reasonable doubt could be introduced
- Officer identified the driver of the vehicle
You could ask about the communication, but this will not be a strong defence to pursue in terms of raising reasonable doubt. Just my $0.02.
