Drunk Driving Defense, DUI Arrest - FAQs
17. Can you define a rising BAC defense
?
The state of California states that it is against the law to have a high blood-alcohol concentration while driving, not at the time the chemical test is administered. Science shows that it can take between 30 minutes to 3 hours for the alcohol to be absorbed into the system. With this in mind, a suspect's BAC could continue to rise after he was stopped and arrested.
Typically, there is an hour gap between the time the suspect is arrested, and when a chemical test (blood, breath, or urine) is administered. Perhaps the test result showed a .10% BAC. If the alcohol was still being absorbed into the suspect's system since the arrest, this could mean he only had a .07% BAC while he was driving. Basically, although the test result showed an illegal BAC, the suspect’s true BAC while driving was still legal.
