Negative breathalyzer test results can be frustrating. This is especially true if it happens in the presence of a police officer. Negative breathalyzer tests can spell big trouble for drivers who’ve been pulled over for a traffic violation. If convicted of DUI, drivers must use an ignition interlock device for a number of months until their sentence is over. Using an interlock device ensures that no one, including the owner of the car, drives the vehicle under the influence of alcohol. The car will only start if a successful breathalyzer is completed prior to starting the ignition. There are several things, though, that can affect the breathalyzer reading. Understanding what can disrupt a clean breathalyzer can make life with an interlock easier.

Proper Interlock Device Calibration is Required

Breathalyzers don’t simply work on their own. Professional devices need maintenance and calibration to work properly. Even little differences can impact someone’s ability to drive. It’s important to know that your interlock device is working correctly, particularly because authorities review test results. The margin of error for each breathalyzer test should be no more than .02 percent. A malfunctioning device is likely the reason for anything higher. A maintenance professional can get the device back in working order.

Outside Influences

The biggest reason interlock device breathalyzers register a negative test is user error. A lot of people, when they begin using the device, don’t know how to position it correctly. They also don’t know how long or how strongly they need to blow. Even things like burping or whether you’ve recently used mouthwash can affect results. Knowing how to use the interlock device the right way is imperative. Believe it or not, even police officers sometimes administer breathalyzers incorrectly. When this happens, the consequences can be severe. Every year, many people are convicted of DUI because of poor breathalyzers.
