What Type Of Breathalyzer Do Police Use

Breathalyzers At The Police Station

Portable breathalyzers tested against police unit

A breathalyzer at a police station is different from the one law enforcement officers have on the road. Its a much larger and more advanced machine that also measures breath alcohol. Heres what it looks like:

In Montana, most agencies use the Intoxilyzer 8000 manufactured by CMI Inc. This machine weighs almost 18 pounds and has a variety of improvements over the PBT. The Intoxilyzer 8000 analyzes alcohol using infrared spectroscopy, rather than the somewhat archaic fuel cell method of the PBT.

Without giving a science lesson, infrared spectroscopy is where infrared light passes through a sample of your breath. This breath is also deep lung air, just like with the PBT. Any alcohol molecules in your breath sample will actually absorb some of the radiation of the infrared light. The machine measures the amount of infrared radiation that hits the other side of the chamber against the amount that was started with, and the difference is a measurable amount of alcohol molecules that were present in the sample.

Preliminary Breath Tests Vs Evidential Test Devices

Preliminary breath tests, or PBTs, are portable devices that are used in the field by LEOs prior to an arrest for intoxicated driving. Motorists are not required to submit to a PBT. However, if a driver refuses to undergo a PBT, he may be required to submit to an evidential breath test or a blood test. Virginias implied consent laws indicate that all motorists must have their blood alcohol content tested if law enforcement has reasonable cause to suspect intoxication. A driver who refuses either an evidential breath test or a blood test may face a suspended license and criminal charges and the refusal may be used as evidence in a criminal prosecution for impaired driving.

While PBTs are not as reliable as evidential breathalyzer tests, they are still subject to minimum requirements for accuracy. The Department of Forensic Science in the state of Virginia has approved multiple PBTs for use by law enforcement officers to determine if a motorist is likely impaired. Approved PBT devices include:

  • Devices manufactured by a Missouri company called Intoximeters, including the Alco-Sensor as well as the Alco-Sensor II, III and IV
  • Devices manufactured by Lyon Laboratories in the United Kingdom, including the CMI SD2 and SD 5
  • Devices manufactured by CMI, Inc. in Kentucky including the Intoxilyzer 400PA
  • Devices manufactured by Lifeloc Inc. including the Lifeloc PBA 3000 and FC10

A Breakdown Of Alcohol Testing

Breathalyzers and other such alcohol testing devices aim to measure the alcohol content found in alcoholic beverages. This alcohol is called ethanol or, in other words, ethyl alcohol. When you consume any such beverage, this ethanol shows up in your breathe because as it gets absorbed in a process by a number of your body parts like the mouth, throat, intestines, and stomach. Once it is absorbed, it is transferred into your bloodstream.

The thing with alcohol is that it is not digested immediately after being consumed and is also not affected by any chemical reaction that takes place in your bloodstream.

As the blood travels through your lungs, some of the alcohol that your blood absorbed earlier finds its way into the air sacs present in your lungs. These air sacs are called alveoli and through them, the alcohol moves into the air. This is where breath testing devices come into play. The alveolar air contains a certain amount of alcohol concentration which is relative to the alcohol concentration found in a persons blood. When you exhale this alveolar air that does have traces of alcohol in it, these devices can instantly detect and identify the presence of alcohol.

This whole process is why breath testing devices for blood alcohol have become so popular and common. When using them, you no longer have to draw a persons blood in order to test their alcohol level. All you need to do is test their breath to check if they have been drinking and driving.

Use Of Preliminary Breath Test Or Preliminary Alcohol Screening Test In The United States

Prefessional Police Portable Breath Alcohol Analyzer Digital ...

In the US, the primary use of preliminary breath test or preliminary alcohol screening devices is for screening and establishing probable cause for arrest, to invoke the implied consent requirements.

In US law, this is necessary to sustain a conviction based on evidential testing . In order to sustain a conviction based on evidential tests, probable cause must be shown . Police are not obliged to advise the suspect that participation in a FST or other pre-arrest procedures is voluntary. In contrast, formal evidentiary tests given under implied consent requirements are considered mandatory.

Refusal to take a preliminary breath test in the State of Michigan subjects a non-commercial driver to a âcivil infractionâ fine, with no violation âpointsâ, but is not considered to be a refusal under the general âimplied consentâ law. In some states, the state may present evidence of refusal to take a field sobriety test in court, although this is of questionable probative value in a drunk driving prosecution.

Different requirements apply in many states to drivers under DUI probation, in which case participation in a preliminary breath test may be a condition of probation, and for commercial drivers under âdrug screeningâ requirements. Some US states, notably California, have statutes on the books penalizing preliminary breath test refusal for drivers under 21 however the Constitutionality of those statutes has not been tested.

Problems With Breathalyzer Tests

There are several factors that can complicate the results of a breathalyzer test. If you have recently used an alcohol-based mouthwash, the machine can detect it. There are also varied results if you hold your breath, hyperventilate or run before taking the test. Other medical conditions or even the types of food you have eaten can all affect the tests. Due to the many errors that can occur during a breathalyzer test, it is common to have a false positive result. To be sure your breathalyzer test results are properly used in your case, you should contact a DWI attorney in San Antonio TX, like Jesse Hernandez.

You should never drink and drive, but if you have been arrested for a DWI, you should immediately contact a DWI attorney in San Antonio TX like the Law Offices of Jesse Hernandez to support you in your case.

Other Causes Of False Positives

If you have been pulled over and charged with a DWI in Rochester, and you absolutely dispute the accuracy of the Breathalyzer Test administered to you, it is important to consider whether any of the following might have led to the questionable results offered by the test.

Ethyl alcohol, found in alcoholic beverages, is similar to Methyl alcohol, which is found in breath molecules. Acetone, found on the breath of Diabetics and those on low-calorie diets, can cause a false positive. High protein diets release more ketones, also resulting in false positives.

Blood, alcohol, or vomit present in the mouth can lead to a false positive, as can temperature fluctuations. Both human and ambient temperatures can cause some interference. Police radios, mobile phone, dirt, and moisture can all affect a Breathalyzer Test. Even smoking a cigarette, vigorous physical activity, and intense anxiety can affect the results . Some reports have shown that drinking tea and eating ice cream can also result in false readings.

What To Look For When Buying A Breathalyzer

There are only a handful of companies that make breathalyzers for the general public but even so, the products on the market have some significant differences. When buying a personal breathalyzer, consider:

Price: The cheapest product we tried was about $40 and the most expensive $131. Generally, the more expensive breathalyzers do tend to be more accurate and reliable, but you don’t need the same level of detail for recreational use as, say, a police officer would. If your reading is at all borderline or uncertain, you can always just wait a little longer and test yourself again later.

Accuracy and reliability: Virtually all major breathalyzer manufacturers claim “professional” or “police-grade” accuracy, so it can be difficult to determine which devices actually deliver on that claim. Since accuracy is crucial in staying safe behind the wheel, we conducted trials to test the accuracy of each device so that we can tell you which ones live up to their price tag. And we found price does not denote reliability.

Result readability: Some breathalyzers will display your BAC right on the device, while others have an optional or mandatory Bluetooth smartphone connection. The latter can be useful if you want to store your results in a log. But if you don’t have or don’t want to use a smartphone, skip this feature and be sure to get a standalone device.

What Is A Breathalyzer

There are two types of breathalyzers that police officers use throughout the United States. Typically, they are either small, hand-held devices or larger ones found in police stations. If you are pulled over by a police officer in Oregon and they suspect you are driving under the influence of an intoxicant , a breathalyzer may be used to help verify their suspicions.

In Oregon, if a police officer suspects you are impaired, you will likely not be offered to blow into a handheld device at your vehicle. Typically, if they suspect that you are driving while impaired, you will be arrested for suspicion of DUII and brought to a police station to test your blood alcohol content . The machine most often used for this in Oregon is called the Intoxilyzer 8000. If the machine determines you have a blood alcohol content of .08 percentage or higher, you will be presumed as legally intoxicated. The reading from the breathalyzer may also be used as evidence against you in court.

What Happened To Breathometer On Shark Tank

Breathometer was a device that claimed to measure someones blood alcohol content using their iOS and Android smartphones. However, the app proved unreliable, and was shut down by the Federal Trade Commission. Breathometer was founded in September 2013 by Charles Michael Yim, who is the companys current CEO.

Is buying a breathalyzer worth it?

At the end of the day, if you think youre likely to be walking the line between sober and drunk when you need to take the wheel, you should definitely purchase a breath analyzer. Breathalyzers can let you know when youre way over the line and when youre good to go.

Does peanut butter help pass a breathalyzer?

Failed Alcohol Test: What Will Happen

Failure to comply with the alcohol driving limit is punishable by law. Penalties have also been more severe throughout time, primarily to assist in regulating alcohol-related incidents. Furthermore, punishments for first-time to repeat offenders who exceed the legal alcohol limit could include:

  • Penalty notice fines
  • Prison terms for mid and high-range Prescribed Concentration of Alcohol
  • Driving disqualifications minimum of three months
  • Alcohol interlock program

Thus, owning a reliable personal breathalyzer from Breathalysers Australia are available with the same sensor as the Australian police breathalyzer can accurately measure your BAC level and help you avoid such severe penalties. Breathalysers Australia provides a selection of BACtrack personal breathalyzers for people to check to see if their BAC is over the alcohol driving limit before getting behind the wheel.

Infrared Analysis Vs Fuel Cell Technology

Infrared breath tests such as the Intoxilyzer 5000® are a very common type of breath test technology but are not the only type. Fuel cell technology is also frequently utilized to measure an individuals blood alcohol content. The different testing procedures work in different ways. For example:

Infrared Instruments are the most commonly used breath tests because they are stable and reliable and may be automated. The theoretical basis for IR tests are based on the Beer-Lambert Law of Absorption, which demonstrates that molecules absorb electromagnetic radiation at their own specific unique wavelengths. Each molecule has its own infrared fingerprint, including Ethyl Alcohol, which absorbs radiation at wavelengths of approximately 3.0, 3.39, 7.25, 9.18, 9.50 and 11.5. Because no other compound absorbs radiation at all of these wavelengths and only at these wavelengths, a greater absorption of these wavelengths means a higher concentration of alcohol exists. When an IR test is performed, an individual breathes into a sample chamber and an IR energy beam emerges. Energy loss at the appropriate wavelengths is then measured to determine the level of absorption and thus the amount of alcohol that is present. IR tests are generally performed at police stations and are stationary units.

Reliability Of The Breathalyzer

Portable Digital Breath Alcohol Sensor Tester Pro Breathalyser Police ...

Breath analysis is probably the most commonly used technique by law enforcement to attempt establishing that a suspect was driving with a prohibited amount of alcohol in their system . The reliability of this test has been called into question.

Some scientists and experts contend that breath tests, as they are currently administered by police, are very inaccurate . Some courts have even thrown out breath test results because of their unreliability.

In 2002, the Washington Supreme Court ruled that a woman could not have her driver’s license suspended because of reliability problems associated with the alcohol breath test.

The woman challenged the administrative suspension of her driver’s license, by taking issue with the reliability of the thermometers used in breath-test machines.

Thermometers are used to test the machine’s accuracy. Operators test the machines by taking a reading from an alcohol/water mixture. The mixture must be kept at 34 degrees centigrade, which is where the thermometer comes in. The Supreme Court ruled that because evidence was not produced to establish that the thermometer used on the machine was certified as reliable, her license could not be suspended.

At least one court has even reversed DUI convictions on the grounds that breath tests are inherently unreliable. In State v. McGinley, 550 A.2d 1305 , the New Jersey Superior Court, Law Division, considered the consolidated appeals of four defendants whose convictions involved Breathalyzer tests.

When Is A Breathalyzer Or Intoxilyzer Test Performed

The police will make a breath demand when a person is exhibiting obvious signs of impairment. For example, when a person who is flagged over by a R.I.D.E. program is slurring their speech, there is an odour of alcohol on their breath, they are unsteady on their feet and they are driving badly the police will make a breath demand. In this situation, the police would not have to provide him or her with an approved screening device demand. They would likely immediately arrest the person, based upon reasonable and probable grounds that their ability to operate a motor vehicle is impaired by the previous consumption of alcohol.

Upon arrest, the police officer would then read a formal demand to provide breath samples at the police station. Again, this is a completely different situation from an approved screening device demand. It is not necessary for the police officer to go through the approved screening device demand procedure if they have reasonable and probable grounds that the person is impaired upon observation. Merely exhibiting an odour of alcohol and perhaps bloodshot and glassy eyes would only lead to a suspicion that the person had been drinking and had alcohol in their system It would not lead to reasonable and probable grounds that they are impaired or over the legal limit.
