Understanding BAC results
The displayed result is an estimate of the test subject’s BaC.
a breath alcohol tester cannot determine the exact BaC in the blood
of the test subject. Correlation between BraC and BaC depends on
many factors, such as temperature and health conditions. Therefore,
only use this device as a tool to screen for the presence of alcohol.
Many people consider a 0.02% or greater a positive test for alcohol
in “zero tolerance” screening. Most states have 0.08% as the legal
BaC limit for tasks such as operating a motor vehicle. some states
prohibit driving commercial vehicles or any vessel with a 0.04%
BaC or higher. Many states and countries prosecute individuals for
driving under the influence at any level.
