When pulled over under the suspicion of driving under the influence in California, the police may try to subject you to a breathalyzer test. The breathalyzer is the tool that they use to make a high percentage of arrests due to drunk driving. This does not mean that breathalyzers are always accurate, however. Most civilians do not question its validity. If you ask the prosecution, breathalyzers receive a lot of praise. However, if you ask researchers, you may discover a different opinion.

According to ZDNET, a software engineer and security researcher examined breathalyzers and discovered faults with the devices. They are capable of providing incorrect results that may lead to the arrest and prosecution of innocent civilians. With the threat of a lawsuit from the breathalyzer manufacturer, research halted on the tests.

A person’s breath temperature can change the results of a breathalyzer test. If your breath temperature is one degree higher than the average, your results raise by 6%. This is more than enough to raise your alcohol blood level to an extent that leads to your arrest. Human breath temperature is in fluctuation all day. Your breath may possibly be higher than normal during a traffic stop. Research also frowns on the sensor or fuel cell. Fuel cells degrade and this can change your test’s accuracy. The truth is that police do not calibrate the breathalyzer tests as often as they should. Researchers put the validity and the capability of alcohol breathalyzer tests into question.
