I got lit up for 83 in a 70 in Schertz today. I took my father to Randolph AFB to get his insulin and other meds and was trying to get it home in somewhat of a hurry. We had it on ice but he didn't want to risk it.

There was a grey Dodge truck in front of me that was hauling ass in the left lane. I changed lanes from the middle to get behind him and as soon as I changed lanes, I saw the officer sitting on the overpass above us running radar.

I pulled over at the rest stop and he was nice and respectful. He ran my shit and came back and thanked me for being honest and up front with him but said to keep the highways safe, he had to write me the citation for 83 in a 70.

He said he clocked me at 81 but locked Laser at 83? Wtf?

He also put that MY truck was grey (Like the dodge) but my truck is brown.

I KNOW I was speeding so I am not complaining but I know I was doing 75mph, not 81 or 83.

The LIDAR (laser) beam is very narrow and aimed at one vehicle at a time. When he said he "clocked" you, that means he visually estimated your speed. With training and practice you can get VERY good at it.

Well how did he "clock" me and use laser to lock me in at a speed in which I was not traveling?

I'm being absolutely positively serious when I was say I was doing 75. I always do 75 on I-35 especially near Schertz and Selma. I know there are always cops there.

Sounds like he clocked the Dodge and you got stuck with the ticket because you pulled over first. You can always try going to court and protesting. If you get a sympathetic judge he may let you off, especially if the officer doesn't show up for his court date (as sometimes happens). If not you are out your time. Can you just take defensive driving and only be out the $$$? Another question to ask, was the unit who wrote the ticket the same one that took the laser reading? If not you might question whether he mistook the vehicle from the other unit's description and pulled over the wrong person. If he had to drive all the way from the top of the overpass down the onramp and then catch up to you in traffic by the time he caught up to you he may have forgotten the details. Ask when he actually got your plate number. There are LOTS of pickups in Texas that all look basically the same. I see a 1/2 dozen Silverados that look just like my wife's every day on the way to and from work.

But really... 83 "keep the highways safe". Hah, what a crock of excrement. Schertz is notorious as a speed trap.

Why do people ask questions then argue with the answer?

Whatever man, fight it in court. What do you expect to read here?

Oh yeah, I forgot; it is ALWAYS the other car.

You know if the officer was not wearing his hat the ticket won't stick, right?

But even the best can occasionally make an error. And as I've said previously... there are a LOT of trucks that all look alike. In heavy traffic it would be pretty easy to make an error every now and then when you are looking at tens of thousands of vehicles a day.

Wow, who's all defensive. I am honestly asking, not trying to argue with you but you're always the correct one, I guess.

"It's ALWAYS the other car"

Keep your shitty attitude. I know I was speeding but I wasn't doing 81. That's the whole reason I started this thread.

I'm not going to fight it so I don't give a shit what "hat" he was wearing or any other "reason" to try getting out of a ticket.

When you ask specific questions and then respond to specific answers with, "well, the how did he blah, blah, blah" you ARE arguing. Frankly, I don't give a fuck.

If you not going to fight it why are we here? If you just need to get it off of your chest I'll just shut up then and not interfere.

Hope it works out for you though.

How do you know this? Have you recently had your speedo checked? GPS? etc. Operator/Mechanical error works both ways.

Even if you intend to just pay, it doesn't hurt to plea not guilty and request a jury trial.

Requesting a jury trial will delay things atleast a month if not longer. When you are mailed the court date they will schedule a pre-trial hearing where you can change you plea if you choose to. There is also always a chance they will just drop the thing altogether before trial.

Schertz is only about collecting $$. I wasted my time fighting a speeding ticket there and all I did was waste a day of work. No one was getting a break that day in court. My best advice is pay it and be done with it.

In my experience, they are extremely accurate.

Schertz = a bad place to speed. With that said, the lasers are very accurate and not only give you the speed, but the distance as well. By clocking, he meant that the laser (or possibly radar) checked you at 81, but when he was able to lock the speed on the laser (meaning keeping it more than a moment), it was 83. Our lasers always lock the speed every time we pull the trigger so clocking is locking, but I suppose there are models out there that differentiate.

As to the color differentiation, are we talking completely dark brown brown, or are we talking a light tan that could be mistaken as grey? I'll often put a nearest approximation for a color when it is one that could really go either way and what the owner thinks is the color may differ from what I think. I've had people tell me their black cars were dark blue and vice versa, their blue cars were green, their red cars were orange, their white cars were light grey, etc.

There is also only so much room on the "Color" box and it would be a little hard to write "Vehicle Color: Grayish, but very light, so as could easily be mistaken for brown given the right lighting and circumstances. In fact, many people if asked may indeed state that the vehicle is brown, but from the angle and lighting that I am currently observing said vehicle under, it appears gray to me."

Also, with the laser, there is no mistaking the vehicle you checked. It has a little scope with a red dot on it, and if that little red dot sight is good enough for a marksman to put a bullet through a hole at 300m +, it is good enough to not mistake one vehicle for another at 200 feet.

Thank you very much!

I was more interested in how it works. He got me, whether it was 83 or 75 so I wasn't trying to figure out how to get out of it or complaining. I just thought it was odd.

The Dodge was a greyish silver and my truck is desert brown but after looking at pics online, I can see how he might have mistaken it for grey I guess.

Not mine but same color

The laser is pinpoint accurate. Radar, on the other hand, is a different story. Good luck! At least go to court. Or is there an option to do Defensive Driving?

To answer your question LIDAR shoots a 36 inch cone. They are very accurate.

A LIDAR speed measurement device's specs are dependent on the manufacturer. Our's are made by Stalker so I will use that as and example. Its speed measurement is accurate to +/- 1MPH and its range is accurate to +/- 1 foot.

If so, why did you not ask the question in the first place?

It works by sending out a laser beam that hits the target and is reflected back to the device. The device uses the laser beam to determine the distance to the target. The device sends out multiple laser pulses per second. It takes the change in distance between the pulses and calculates an average speed over a span of time. The device can do this in approximately half a second or less.

Yes, operator error can give erroneous speed readings. Proper training gives the operator the ability to recognize and ignore improper speed measurements.

A 36 inch cone would be an improper description. A beam width of 36 inches at 1000 feet would be more appropriate.

The LIDAR is more accurate than your speedometer. And this is from personal use of the same model LIDAR they are using. It's very easy to discriminate between vehicles on the highway and the light beam is very narrow so theres little chance of getting the wrong vehicle.

^this

also OP, keep in mind factory speedometers are not certified accurate.
from what i recall there is a variance of 6-12% allowed

get/borrow a GPS & validate where yours is at...you may be surprised.
mine was 8 mph off - i got a tuner & corrected it

The devices can be very accurate, the humans operating them not so much. My buddy (cop) displayed this for me by shooting radar on a tree that was moving at 10 mph.

They are extremely accurate and the only thing that will throw them off would be operator error. They run a self check constantly and throw an error code if something is wrong. Is your truck stock? Did you change the wheels or tires?

Accuracy isn't the issue. LEO witnessed you speeding and he verified with xyz device. He could have been using his own speedometer, radar, laser, milemarkers, or whatever he determines the best to use. Heck, I've had AUSTIN PD laser a car a few paces in front of me and then call in all the cars around it, assigning what he clocked the other guy. Traffic court applies guilty until proven innocent so be warned if you want to take that dance.

OP, you know that town is famous for being a speed trap. Nolanville as just as bad, if not worse, 20 years ago until the state shut them down.

Forget it, the system is set up to fuck you from the start. You WILL pay no matter what, it's all about revenue generation and nothing to do with "interstate safety". What a load of bullshit, lol. A revenue generator's(Police Dept) budget is a mere fraction of what they make harassing the citizenry with citations.

However, there is one surefire way to never get a ticket, be a cop. It's called "professional courtesy".

Most or something upwards of 80%+ of the money you hand over to a municipal court clerk goes to the STATE OF TEXAS. Not the city/town.

I could get an actual figure if you cared to know.

20% seems to be plenty for Schertz. Nice Municipal court building and nice police cars.

I KNOW I was speeding so I am not complaining but I know I was doing 75mph, not 81 or 83.

you were speeding, you got popped, pay your tax for being "kept safe" and move along

Honda allows for 10% over or under actual speed before they will fix the speedometer.

mine was 8 mph off - i got a tuner & corrected it

FYI it is 4% that is supposed to be the limit of inaccuracy on new production vehicles.

Honda allows for 10% over or under actual speed before they will fix the speedometer.



How do they calculate a percentage tolerance in a speedometer? 10% at 80 is a whole lot different than 10% at 15.

If a speedometer is not accurate, but precise enough to hold a consistent inaccuracy through all different speeds it would seem kind of stupid for a company not to fix it.

Most or something upwards of 80%+ of the money you hand over to a municipal court clerk goes to the STATE OF TEXAS. Not the city/town.

I could get an actual figure if you cared to know.




I think that depends on the size of the city because the legislature enacted this years ago to go after those rouge towns which relied @80% taxes on speeding tickets (ie Nolanville). Smaller towns are forced to push their ticket revenue to the state and I think all red light tickets require 50% to state.

If you dont give a fuck, then you probably have no need to post in the thread and act like an ass.

Well how did he "clock" me and use laser to lock me in at a speed in which I was not traveling?

I'm being absolutely positively serious when I was say I was doing 75. I always do 75 on I-35 especially near Schertz and Selma. I know there are always cops there.


Why do people ask questions then argue with the answer?

Whatever man, fight it in court. What do you expect to read here?

Oh yeah, I forgot; it is ALWAYS the other car.

You know if the officer was not wearing his hat the ticket won't stick, right?


Wow, who's all defensive. I am honestly asking, not trying to argue with you but you're always the correct one, I guess.

"It's ALWAYS the other car"

Keep your shitty attitude. I know I was speeding but I wasn't doing 81. That's the whole reason I started this thread.

I'm not going to fight it so I don't give a shit what "hat" he was wearing or any other "reason" to try getting out of a ticket.


When you ask specific questions and then respond to specific answers with, "well, the how did he blah, blah, blah" you ARE arguing. Frankly, I don't give a fuck.

If you not going to fight it why are we here? If you just need to get it off of your chest I'll just shut up then and not interfere.

Hope it works out for you though.

However, there is one surefire way to never get a ticket, be a cop. It's called "professional courtesy".


Well...somebody needs to head out to Matador Texas and tell the one and only 14 year old deputy about this. He wrote me for 74 in a 70.


never even heard of matador Tx, was he driving an old pickup with a red bubblegum light and wearing blue jeans and a starched white shirt or something?

If he's 14 years old and driving a pickup, he needs to ticket himself. Corrupt little bastard.

The models we use are also 3 feet wide at 1000 feet out. It's pretty tough to screw up which car you're measuring with laser. Laser tickets are extremely easy for us to win in court because of the precision of the instrument. Radar is another story.

As a few others have mentioned, it's very common for speedometers to be off by 5-10mph at highway speeds. Check it against a GPS speed sometime, and you might be surprised - every car I've tried it with was at least 5mph off.

Does the laser model you use take a picture of the car showing speed?

Does laser work at night?
I remember reading years ago when laser first came out that the headlights of vehicles
(which would be usually at night) interferes with the laser beam. So some people advocated
driving with your headlights on in the daytime in case laser was being used on your vehicle.

Different wavelengths, I don't see why it would interfere.

Then the courts are relying on the sworn statement of an LEO that claims their laser unit determined John Doe was driving XX when in fact there is no way to verify actual speed/violater except by the two parties involved. I know Texas doesn't allow the roadside cameras due to the belief that a person should be able to confront their accuser (or something to that effect). The "laser tickets are extremely easy for us to win in court because of the precision of the instrument" is akin to holding a shooting competition and awarding a winning prize without ever demanding to see the winning target.

Whatever happened to solid PROOF? All a judge/jury has is are words.

As individual sworn officers, we have everything to lose by lying and nothing to gain by making up speeding violations...or anything that we report for that matter. Police would be highly ineffective if nothing we said stood for anything in court. Enough people speed that we don't have to get creative. I STILL try to get as many violations on camera as possible though. Most of the time, I tilt the camera down to get the readout of the laser as I'm writing the ticket (displays speed and distance).

Does the camera show a picture of the car when it was lasered or are you showing a picture of the laser readout only? I ask because I can get my rangefinder and take a picture of it showing distance to a target, then show the target with a hole in the bullseye. Combine the two and I'm the most awesome shot there is. How many people here would call BS? Then why is it a shocker that folks would question an LEO's sworn testimony? Not sure where you work but I've seen plenty of creative traffic cops.

No, the vehicle that is measured won't show up on camera until it's in front of the patrol car. Playing cinematographer on top of being a cop is a stretch haha. I just show the laser once I feel safe to do so (after making contact with the driver). Being questioned is no shocker, it's healthy and that's why court exists. We don't have a dog in the fight though, which is different than the defendant.

Our dept sees $0.00 from every ticket we write. It all goes to the county. Care to try again?

Traffic court applies guilty until proven innocent so be warned if you want to take that dance.

OP, you know that town is famous for being a speed trap. Nolanville as just as bad, if not worse, 20 years ago until the state shut them down.


So you know that he assigned your speed to the other driver because you two are best friends and were coordinating your speeds that day while driving down the highway?

Most or something upwards of 80%+ of the money you hand over to a municipal court clerk goes to the STATE OF TEXAS. Not the city/town.

The amount any government agency can collect from citation fines is regulated by the State. As far as I know, it's uniform throughout the state of Texas.

Out of a $150.00 ticket $105.00 goes to the state.
