DUI Convictions: Faulty Alcohol Breath Test Machines

For years, drivers throughout Florida have had DUI convictions based on false readings from defective alcohol breath test machines.

Impossible Results

The problem was found by defense attorneys. They 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. But humans have a maximum lung capacity of only about five liters.

This is important. Accurate measurement of the volume of air blown into the machine is essential for an accurate estimate of BAC. (BAC is blood alcohol concentration.)

A breath test is one of the most powerful pieces of evidence in DUI convictions. If a machine reports that a person’s BAC was above 0.08, Florida law requires that a jury assume the driver was guilty.

State Negligence

The defective machines were used for years. The  Florida Department of Law Enforcement (FDLE) was responsible. State officials never tested a key component. Nor did they perform required reviews of breath tests.

DUI convictionsAfter learning of the problem, FDLE quietly started fixing machines. They then returned them to service. Inspectors began the process of checking every machine in the state. They found that about 40% of the machines checked were defective.

Yet FDLE did not inform those who had DUI convictions based on the faulty machines. Many were victimized twice. First by the faulty machines. Second, by uncaring public officials who disregarded basic decency.

Don’t be a Victim

Protect yourself. Don’t become an innocent victim of a defective alcohol breath device. Or of callous officials in any state.

To do so, don’t drink and drive. Use a designated driver, a cab, or public transport. Use an Uber, or ask a friend to drive you home.

If you must drive after drinking, stay completely sober.  Don’t get any DUI convictions.

Standard Drinks
    • Remember that standard drinks of beer, glass of dinner wine, or shot of spirits (liquor) has the same amount of pure alcohol.
    • Pace your drinking. No more than a drink an hour.
    • Have a non-alcoholic drink between alcoholic ones.
    • Eat food as you drink.
    • Take your time. Sip your drinks. Enjoy their flavors and aromas.
    • Don’t try to “keep up” with the drinking of others.
    • Have a drink only when it’s consistent with your pacing schedule.
    • Be very cautious with punch. Also with containers of unusual shape or size. It’s hard to judge their alcohol content. This makes it hard to pace them.
    • Follow any medical advice about drinking with your meds.

Better safe than sorry. Avoid DUI convictions. Or DWI charges.
