Florida DUI Convictions Based on False Alcohol Breath Test Machine Results

For years, drivers throughout Florida have been convicted of driving under the influence (DUI) based on false results from defective alcohol breath test machines.

The problem was recently identified by defense attorneys who noticed that the machines (Intoxilyzer 8000) were reporting impossible results. For example, one machine reported that some drivers blew 10, 11, and even 12 liters of breath into the device. However, humans have a maximum lung capacity of only about five liters.

This is important because an accurate measure of the volume of air blown into the machine is absolutely essential for accurately estimating blood alcohol concentration (BAC).

The breath test is one of the most powerful pieces of evidence in DUI trials because if a machine reports that a person's BAC was above 0.08 percent, the law in Florida requires that a jury assume the driver was guilty.

The defective machines were used for years because state officials never tested a key component or performed mandatory reviews of breath tests. After learning of the problem, Florida Department of Law Enforcement (FDLE) quietly started fixing machines and putting them back into service. When inspectors began the process of checking every machine in the state, they found that about 40 percent of the machines checked were defective.

Unfortunately, FDLE officials did not inform defendants who may have been wrongfully convicted or unfairly lost their driver's licenses after being tested on the flawed machines and then convicted. Thus, the victims were unable to challenge their unjust convictions.

Protect yourself and don't become an innocent victim of a defective alcohol breath tester or indifferent public officials in any state.

To do so, don't drink and drive. Use a designated driver, a cab, public transportation, or ask a friend to drive you home.

If you must drive after drinking, stay completely sober:

Better safe than sorry.
