not that I'm advocating for better breathalyzers, but weight scales can be recalibrate to ignore the base weight, if you put a 5 pound brick on it, you can recalibrate read the weight with the brick as 0. breathalyzers should do this before each reading

the problems come when people start to "fool" the machine and won't blow enough, with the belief that a little blow will give a lower reading. and the system here in Denmark has a certain flowrate before it activates a legit reading.. so a user that low blow 1 or 2 times and don't get a valid reading and fx claim bad lungs etc.. can sadly have tainted their results in an unfavorable way... though these tests are only indicators and here in Denmark you will get a blood analyze-work as even the bench Infrared cell machines are not valid in court here. as far I know. though I reckon all officers are familiar with these risks. I don't know how pronounce left-overs are in the 3 variants, like semiconductors. fuel cells, and infrared..semiconductor BAC meters are usually consumer-grade devices..

You need to look into THC breathalyzers and see what could set those off to have a false positive

I think you should have blown first to show you haven't been drinking or using hand sanitizer, then the synthetic breath, then blown again. I do appreciate the video. I am extremely interested to see why these machines have so many false results and yet they are used. Once you are charged for the dui, your screwed because from there on out they will always be on the lookout and then test you every time you get pulled over or come into contact with the police.

I don’t know why I’m here, but I certainly am interested

also the device used is made and intended to show alcohol in the device,,not thc, or meth, or pills , you have to understand the use of an alcosensor before trying to find ways to cheat it ,,it wont lie, any person who has ever been trained to use one knows the reason of one and its usefulness

during the demonstration you miss procedure of verifying that the ALCO_SENSOR is back to .00, if you understood the instrument you would know how the instrument works,, all info is completeley false

Mr green sir the inventor of the breathalyzer has stated in court you question s are you the officer are you trained incoming road side breathalyzer tests how long next when was the breathalyzer last checked and how many people have you tested this evening on that machine did you know that there is small residuals left behind in the machine after each use this is true next the inventor of the machine question one are you the inventor yes is the machine 100% accurate answer no its not

You are not using it correctly! After each sample you have to hit the set button and leave it set! This will allow it to dump the charge that was produced by the fuel cell. All of the alcohol in the sample was oxidized by the fuel cell the moment you got the .080. The reason that you are still seeing numbers is because there is a 1000 ohm resistor in the circuitry to slow that discharge voltage so that an officer can see what the results are, and have time to make a calibration if need be when putting on it a gas canister. Then when you hit the set button it shorts out the connection, and then allows a different path to dump the voltage, hence the path of least resistance. When you do this as officers are trained to do, and leave the device with the set button pressed, it will clear out in about 30 seconds: then you check it by hitting the read button to check that it is cleared out.

As an attorney you SHOULD understand or read the operating procedures of using an alcosensor before putting out a video completely disregarding the rules of using one, the operating procedures tells you how to use one and how to purge the engine of residual alcohol before reusing. This video is very misleading

I'm here from catfish and carp lol

The "have a good day" out of this defense lawyer's mouth sounded more genuine than the one I got from the officer.

I'm in the trucking industry, so as you would know, we are one big red target for law enforcement, and I have become quite desensitized by law enforcement confrontation. Something I *ALWAYS* do whenever I'm stopped, or in the face of law enforcement accusation is to invoke my right to remain silent pursuamt to the Fifth. I do not answer any questions related to the scope of the charge. This can go a long way with the court, especially if the officer continues to pressure you about the charge that he/she is alleging.

Luke, can you please tell us how to be compliant without answering any questions? Because I don't want to be rude, I just want to be within my rights.

Thank you sir!!!

everytime i've been to court the cop says he had the radar calibrated that morning. EVERY TIME. (even though they most likely didn't) I also live in VA

I always see lawyers with books are they just law dictionary books?

What about the angle of deflection defense? Is it relevant on presenting reasonable doubt, if the officer can't prove at what angle he used LIDAR/RADAR? (Have court in a week from today.)

can you guys make an update because of virginia’s new bill?

It sounds like it’s going off of vibration, whatever your engine rpms are is the speed is it seems

Wow you are awesome 👏 salute to you

Wow that was very helpful and informative. Thank you so much for sharing!!

Y'all are funny I love it.

Wow honey buns ? I don't know what a cliff bar is.

When officer asked me if i was refusing the breathalyzer test, i told him no I’m not refusing, but i don’t understand your instructions without my attorney present. I need my attorney here to advise me. He got pissed and started screaming and barking profanity and commands at me. When it got to court, they saw the video and dismissed the DWI charges. I still had to pay about $1500 in attorney fees, but no DWI on my record. Even if you beat the rap, you still can’t beat the ride!

That was sooo helpful thank you so much

No joke, violating the methodology for the PBT machine invalidates any result.

Thanks for the vid.

Fantastic video my friend thanks for all the great tips I’ll keep this in mind just in case I ever start smoking weed😜

Thank you Mr. Nichols. Very informative video. Now, let's go fishing!

Great to see your making legal videos again

I always tell the officer I'm driving without my pants on. That pretty much makes them leave me inside my car. They can't make you break a law by getting out with your junk exposed.

Is my lights being off constitutional for them not having a reason to pull me? I asked the cop if I was driving erratically or like I was drunk and he said no.

Thank you for your trouble to inform us schmucks that use interlocks [or soon to be].

have you heard of angle of deflection and if so could it be used for a good defense?

alot of people should remain silent

You're great! Thank u for answering many of my Qs! Too bad you're not n CA!! 💜

We used listeine in highschool science when making a simple breathalyzer

In my own tests. Drinking and blowing into my own macheine, I was surprised how quickly it went up when doing 5 or 6 consecutive tests 15 minutes after each drink. My lack of knowledge of the machines internal workings now means I have to go back to the drawing board in experimenting how quickly my body metabolizes alcohol. The driving limit is only 0.05 here in Australia

A thorough, dedicated effort. Thank you for the information. Always good to know what works and what doesn't from someone who litigates and observes in courtrooms every day.

I love these videos. They are one of the best tools for me as s police officer. I have learned so much from DUI defense attorneys on report writing, field sobriety assessments and court testimony. I love getting drunks off the road. Thanks!!!

At about 14 seconds in did he just say "toiletries"? LOL

This video is hilarious. You guys are fantastic.

How about trying a dip of snuff, such as, Copenhagen.

Am I the only one that wanted him to put hot sauce , honey mustard, vanilla , toothpaste , cough syrup and hot sauce on the honeybun, then eat it, washing it down with a mix of orange juice non-alcohol beer and Listerine. Yum yum. 😝🍝🍯

If you want even more fun you could let the company buy you a cocktail or two so that you start with a modest, but real, blood alcohol level. I'm assuming that anything that results in mouth alcohol would supplement the blood alcohol, and therefore increase the reading, but it's always good to confirm though experimentation. Somewhat unlikely, of course, but I can envision having a legal (for those of us not on probation for a prior DUI) BAC of 0.05 as a result of a cocktail during dinner being artificially inflated to 0.08 or so when they give you a breathalyzer test on the side of the road 30 minutes after you used Listerine. Sure, you should be fine when they give you an official test at the station, but you'd need to get arrested, and possibly have your car towed, in order to be cleared of wrongdoing. Of course I'd presume that you have to fail the field sobriety test before they'd give you the roadside breathalyzer test, but some of us have medical issues that could make the test difficult, and I imagine some people just have lousy balance.

How to beat a DUI..... Uber!

Virginia sucks...

what a nice video!

I appreciate you posting this video, it was very educational. Vinny from NY.
