The limitations of a personal breath test system

On Behalf of | Apr 28, 2020 | Dwi |

Whether you like to go out for happy hour after a long day at the office or you work at a bar where customers sometimes buy you drinks as a tip, if you drink alcohol regularly, driving safety should be a priority for you.

There are a number of ways in which people who routinely consume alcohol can limit their risk of getting behind the wheel after having too much to drink and then potentially facing criminal charges as a result.

A common strategy that has become increasingly popular involves purchasing your own breath test unit so that you can determine whether you would fail a breath test during a traffic stop. While these devices can help, it’s important to realize that they are not foolproof and can leave you vulnerable to impaired driving charges.

Personal breath test units generally use the same kind of technology that the devices police use rely on for accurate test results. However, the breath test equipment used by police requires updated software and regular calibration. People charged with DWI can challenge whether a device they were tested with was properly updated and calibrated. Additionally, a lack of training for the officer who administered the test could make the evidence less authoritative in the eyes of the court.

Your personal testing unit, as well as devices in popular bars or restaurants, may not give you accurate results if you have not recently calibrated it or if it has a pending software update that you didn’t download. That could mean that the test shows you a figure that makes it clear you are safe to drive, only for you to fail a breath test during a roadside stop. If you’re facing DWI charges, it’s wise to have an experienced attorney on your side.
