It's illegal to be driving or operating a vehicle with a blood alcohol content level of 0.08% or higher in all 50 states. When being stopped for DUI, breathalyzers are the most common way for law enforcement to measure BAC.
While being the most powerful form of evidence in DUI cases, breath tests are far from perfect. To estimate BAC from breath alcohol content, breathalyzers must assume a certain ratio between the two based on the average person.
The ratio used in a blood alcohol test may not necessarily apply to you, producing faulty results that can be used in your DUI defense. Breathalyzers may also be calibrated, maintained or administered improperly, which may help in your DUI defense.
