Cologne And Interlock Tests: What You Need To Know

Ignition interlock devices (IIDs) are highly sensitive to alcohol, and can detect even small traces of it. While this technology is designed to prevent drunk driving, it can also be set off by other sources of alcohol, such as cologne. Alcohol is a common base for cologne, and the fumes can interfere with breath samples, potentially resulting in a failed IID test. This can have serious consequences, including the inability to operate one's vehicle, revocation of a restricted license, and probation violation. Therefore, it is recommended to avoid using cologne or similar products before driving a vehicle equipped with an IID.

Cologne can register on the IID, potentially causing issues with the court, DMV or probation officer

If you have an ignition interlock device (IID) installed in your vehicle, you may be concerned about the possibility of failing an IID test due to cologne use. While the primary purpose of the IID is to detect alcohol consumption, it is important to understand that other factors, such as certain personal care products, can also trigger a positive reading.

Cologne can contain alcohol, which is a common base for perfumes and fragrances. When you wear cologne, the alcohol in it can evaporate and be detected by the sensitive IID mouthpiece, potentially resulting in a failed test. This can have serious consequences, including your car not starting, the DMV or court revoking your restricted license, and even a violation of your probation.

To avoid any issues, it is recommended to refrain from wearing cologne on days when you need to blow for the IID. This is because cologne can register on the IID, and a positive reading for alcohol, regardless of the source, can be considered a violation. It is better to be cautious and avoid any products that may contain alcohol, as the potential consequences of a failed IID test can be significant.

In addition to cologne, there are other personal care products that you should avoid before taking an IID test. These include mouthwash, breath sprays, hand sanitizers, hair spray, and hair gel. It is important to carefully read the labels of any products you use and opt for alcohol-free alternatives if possible. Additionally, environmental factors, such as extreme temperatures or high altitudes, can also affect the accuracy of IID tests, so it is crucial to ensure your car is well-ventilated and at normal temperatures before testing.

By being mindful of the products you use and following the recommended guidelines, you can significantly reduce the risk of a positive IID reading and maintain compliance with the terms of your DUI/DWI program. Remember, the consequences of a failed IID test can be severe, and it is always better to prioritize your freedom and driving privileges.

Alcohol in cologne can trigger a fail, even in small amounts

Alcohol-based products can cause a person to fail an interlock test, even in small amounts. This includes cologne, which often contains alcohol as a base.

Ignition interlock devices (IIDs) are highly sensitive and accurate, designed to detect even the smallest traces of alcohol. They use advanced fuel-cell technology, which reacts specifically to alcohol molecules in the breath. While this level of sensitivity is crucial for road safety, it means that any alcohol-based product can potentially trigger a fail, including cologne.

The consequences of failing an interlock test can be significant. An immediate consequence is that the vehicle will not start. Additionally, repeated failures may result in the vehicle locking the user out entirely. Failed tests are typically reported to the relevant authorities, such as the DMV or a probation officer, which can lead to further penalties, including fines and court hearings.

To avoid failing an interlock test due to alcohol-based products, it is recommended to avoid using cologne, perfume, aftershave, and other personal care products that contain alcohol. It is also advised to wait at least 15 minutes after using any of these products before taking the test, and to ensure the area is well-ventilated to prevent residual fumes from interfering with the breath sample.

In summary, alcohol in cologne, even in small amounts, can trigger a fail on an interlock test. This is due to the sensitivity and accuracy of IIDs in detecting alcohol molecules. To prevent this, it is important to avoid using alcohol-based products before taking the test and to ensure adequate ventilation in the vehicle.

Avoid cologne and similar products to prevent false positives

Ignition interlock devices (IIDs) are highly accurate and designed to detect even small traces of alcohol. They use advanced fuel-cell technology, which reacts specifically to alcohol molecules in your breath.

However, certain unexpected sources of alcohol, or compounds that mimic alcohol, can interfere with the results. While these instances are rare, it's helpful to be aware of them so you can take steps to avoid an unexpected, failed interlock test.

Perfumes and colognes often contain alcohol, which can be detected by IIDs. This can result in a failed test, even if you have not been drinking. Therefore, it is recommended to avoid wearing cologne or perfume if you are going to be driving a vehicle with an IID.

In addition to cologne and perfume, there are several other products that can trigger a positive reading on an IID test. These include mouthwash, breath sprays, hand sanitizers, hair spray, hair gel, energy drinks, and certain foods and medications. It is important to be mindful of the products you use and avoid using them immediately before taking an IID test.

To avoid positive readings due to contaminants, it is recommended to wait at least 15 minutes after eating or using any personal care products before taking the test. Rinsing your mouth with water before testing can also help clear any residual substances that may affect the results. Keeping your car well-ventilated and ensuring your hands are dry if using hand sanitizer can also help prevent positive readings.

Alcohol-based products like cologne can cause a temporary fail

IIDs use advanced fuel-cell technology, which reacts specifically to alcohol molecules in your breath. The devices are calibrated to detect alcohol at a concentration of about .02 BAC, which means that there is *.02 grams of alcohol in every 100 millilitres of your blood. This means that even a small amount of alcohol on your breath can cause a fail.

To avoid triggering a temporary fail, it is recommended that you do not use cologne or other alcohol-based products before driving. It is also important to avoid exposure to chemical fumes, such as hand sanitiser, perfume, or cologne, right before taking an IID test. Make sure the area is well-ventilated before taking the test and avoid using these products immediately beforehand.

In addition, rinsing your mouth with water before taking the test can help clear out any residual alcohol or other substances that may affect the results. This is especially important if you have recently consumed food or drinks that may contain small amounts of alcohol, such as ripe fruit, bread, pastries, or fermented beverages like kombucha.

By following these precautions, you can significantly reduce the risk of triggering a temporary fail due to alcohol-based products like cologne and ensure a more accurate IID reading.

Use a personal breathalyser to check for alcohol before taking an IID test

If you have been charged with drinking and driving, you may need to install an ignition interlock device (IID) in your car. This device will require you to pass a breath test before operating your vehicle. To ensure you pass the breath test, it is recommended to get a personal breathalyser to check for alcohol before taking an IID test.

A personal breathalyser can help you determine if you are too intoxicated to drive safely. Alcohol breath tests, commonly called breathalysers, measure your blood alcohol content (BAC). The more intoxicated you are, the higher your BAC. It is a crime to drive with a BAC level of 0.08% or higher, which is the federal standard in the US.

Breathalysers are also available for personal use. However, many at-home versions are less sensitive and can have a higher margin of error. A 2014 study found that several personal-use breathalysers were not "sufficiently sensitive to test safety to drive after drinking alcohol". User error can also affect the results of a home BAC test, creating incorrect readings.

While breathalysers sold to the public had an accuracy of 90% or above in the 2014 study, one device was as low as 26%. Even a 10% error rate can contribute to impaired drivers on the road. A 2017 UK study of 208 people's BAC results from at-home alcohol breath tests found that these devices could also overreport BAC. The authors recommended at-home tests as a valuable tool in appraising BAC levels to prevent drunk driving, but emphasised that more studies into test accuracy are needed.

To get the most accurate results from a personal breathalyser, it is recommended to wait at least 15 minutes after your last drink before taking the test. Individual differences in metabolism and body composition can also impact breathalyser results. Weather and environmental factors can also have a minor impact on results, but some breathalysers are designed to minimise these effects.

If you are required to use an IID, it is important to know how to pass a breath test and avoid any issues that could lead to a failed test or lockout. Alcohol can stay on your breath for up to 24 hours after drinking, even after small amounts. To pass a breathalyser test, it is best to completely avoid drinking if you plan to drive. This ensures you pass the breath test and promotes safer driving habits and compliance with your IID requirements.

In addition to alcohol, there are several other chemical sources that can trigger a positive reading on an IID test. These include everyday foods and drinks, personal care products, and environmental elements. For example, mouthwash, breath sprays, and medications can contain alcohol, which can leave trace amounts in your mouth that may affect your breath test results. To avoid this, use alcohol-free versions of these products or wait at least 15 minutes after use before taking your IID test.

Cologne can also register on the IID, turning into a problem for you with the court, DMV, or probation officer. It is recommended to skip wearing cologne on days you need to blow for the IID.
