One more thought...
If it was radar that was used, the judges in the TVB like to hear that your vehicle was the only one in the radar set's "zone of influence".
Zone of influence isn't really a range setting it's a sensitivity setting. There is no way to control the range of the radar - once the beam is transmitted that's it. However, we can simulate a range by having the set ignore returns that are below a certain strength. So, typically the sensitivity setting is on a scale of 1 to 5 with 1 being least sensitive and 5 being most sensitive.
What the officer is supposed to do is verify out on the street what the effective zone of influence is for the particular sensitivity setting - it can vary based on weather, temperature, etc.
So I setup in my spot with my radar and turn it on. I set the sensitivity to "2" and I observe traffic approaching me. I see about how close a vehicle gets to me before it generates a target reading on my radar set. Let's say it's 300 feet. So during that enforcement period my zone of influence is 300 feet.
Now I start doing actual enforcement. I observe vehicles and estimate their speed. The procedure is that we visually estimate a vehicle's speed then confirm that estimate with the radar. Part of the standard testimony we use in NYC is "I visually estimated the motorist's vehicle speed to be 55 miles per hour at a distance of approximately 500 feet. As the motorist's vehicle entered my zone of influence my radar set indicated with an audible tone that it had acquired a target vehicle and I then pressed the lock button on my set to lock that speed reading into my set's display - at the time I did this the motorist's vehicle was the only one in my zone of influence".
Well, in your case that's not true since the truck was in front of you. Yes, there are ways around all of this but I'm guessing an NYPD officer pretty much just goes by what they were taught during radar class at the Highway District - and that's how they are trained.
So if she used radar you can use that basis to raise a doubt and possibly win at a TVB hearing.
Of course, if she used lidar you are SOL - the above doesn't apply with lidar at all (except for the speed estimation part). There is no zone of influence since the lidar can be directed at specific vehicle - radar can't.
Sorry to get into such much detail - maybe it's too much - but there you go. Any questions just ask.
