I defended a ticket today on I-95 in Florida.
The device, Laser Atlanta.
The distance, 1680.0 feet.
The speed, 99 mph
How can the trooper see a car 1680 feet away?

I clocked a silver car with a PL3 at 5200 ft, which is a worse gun overall than a Laser Atlanta.

1680 ft is pretty far away to get a decent tracking history visually to estimate the offenders speed, but well within the capability of any gun.
I assume you won the case?

How did the trooper testify in court? Did he testify that he observed said vehicle speeding and then used his lidar to confirm his observation? I was once targeted by an IL trooper at over 2700ft, obviously he didn't observe crap, he was just using his lidar to pull over speeders.

1680'.. thats a big number, i work in architecture, deal with feet and inches on a daily basis, i know about how far away 1000' is, but, i was curious.. so i found an image of a man holding a sign at 1000'... granted this is a person, and not a car.. but still this is only 1000'.. OP is talking about 1680', significantly more than 1000'

there are a few other examples of images from 100', 250' and 500' as well

I wonder if he was in traffic, and still traveling faster then the rest and the cop targeted him.

Here is a photo of a 1,405ft Lidar trap I recently came across and posted previously.

I have been hit at 2700 feet with a laser Atlanta. All depends on how much traffic there is I suppose, if there is only a couple cars on the road and you are steady then you can get that far pretty easily. Many lidar guns can get out past 6000ft pretty easily. Laser Atlanta's can get out to 12000 ft +. Guns like the TSS have magnification so they make longer shots easier. and when we test we usually shoot at about 2000 ft, it's not hard at all to see the car and target it, that said we are in a low traffic area.... On a busy highway it might be different.

I went with the no points, no conviction, no school, just a fine route; Not much of a defense, tbh. But when an officer says that he visually estimated the speed of the vehicle at 100mph and then activated his laser, the vehicle would have to be 2000' or more away at 100mph. That is over 6 football fields away. The laser beam gradually increases in size and at 1000 feet it is three to four feet in diameter.

I was also hit at 2100-2400 ft with a DE - You can guarantee he would've pulled me over if he got my speed at 2400 ft, even though he really wasn't visible. There's no way he estimated I was speeding at that distance (other than I was in the left lane)

It's IMHO "possible" that officer could get your speed wilt LASER at that or further distances. As to weather or not they could determine which vehicle (within a group) is the vehicle that the reading is being taken on, that would be slim. If you were the only vehicle, well, it's a given.

Now as to an officer Visually Observing your speed and then targeting you with a laser after doing so, IMHO if they aren't using binoculars or some other method to zoom in on you, no f-ing way!

A friend was tagged with a UL LR at 4000ft or more. He was driving PSL+50 and lost his driving licence for 2 months. The LEO was just aiming at cars far enough in order not get spotted and while the drivers hadn't slowed down (he was placed just before the toll booths).

you will have to check the regulations in your area
i had to convert this to metres but it works out that 1680 ft is only 512 meters

different countries and states have different rules . Here in australia WA the limit is 800 metres (2624 Ft ) this was also back when they used ultralytes

Yep, ultralyte range is 1km/1000mtrs on paper, equivalent to 3280.84 feet. Cops would say 800mtr to play it safe and within range 100%.
These things are definitely good to know.
Be good if there's a chart on rdf of each lidar type and distance (if there is, I'd be keen for a look, so point it out) . Very usable in court for a cops long range claims. Can't argue with solid manufacturer specs.

i dont have any recent pics but here is one i have with my old UL compact @ 971 meters (3185.7 FT ) unfortunattly the road wasnt long enough .Spotting and targetting a vehicle at that distance was easy with perfect donditions
