Why You Need to Work With an Alcohol Testing Professional in Cases of Suspected DUI or DWI


As an employer, you know that when a worker gets a DUI, it can impact the workplace. If you are DOT-regulated, there are regulations to follow pertaining to drug and alcohol testing. If the DUI causes an accident on-the-clock or with company-owned vehicles involved, there are liability concerns and legal expenses.

When this happens, you need a professional alcohol testing expert to provide services — or you risk even more legal and financial headaches.

It’s possible for alcohol testing to result in a false positive that leads to a DUI or DWI. Here’s how — and what you can do to avoid this scenario.

False Positives in DUI Alcohol Testing

Improper Equipment Calibration

If you don’t work with a registered Breath Alcohol Technician (BAT), then you run the risk of improper equipment handling that can result in false positives. There are specific rules governing how to maintain and operate breathalyzers and other alcohol testing equipment. Failure to comply can result in inaccurate readings.

Improper Testing Timeline

Mouth alcohol can affect the accuracy of breath alcohol testing results, which is why tests must be administered 15 minutes after the suspected DUI to prevent against false positives. If an individual burps, vomits, or drinks during this time, the 15 minute window must begin again lest the oral fluids compromise the integrity of the test. The alcohol that is measured should be deep within the lungs, not from within the mouth.

If the test is not administered by a trained professional, there is a chance that the proper timeline was not followed and the results may not be correct.

Environmental Contaminants

It’s possible for external contaminants to effect breath alcohol test readings. This can include alcohol from cleaning products, paint acetone, or even residual alcohol from a previously-administered test. Testing professionals obviously have safeguards against these factors, including testing ambient air and swapping mouthpieces between use, but if the operator is unaware of these practices or just conducts them incorrectly, then contamination can occur.
