Multiple Choice

0.08% BAC corresponds to

Explanation:
This BAC value is the legal limit for drivers who are 21 and older. When a driver reaches or exceeds 0.08% BAC, they’re considered legally impaired, and law enforcement can charge them with DUI based on the BAC reading itself. The standard is used to set a clear threshold, chosen because it correlates with noticeable impairment for most people. Breath or blood tests are used to determine BAC, while field sobriety tests assess observable impairment on the spot but don’t establish the legal limit. For commercial drivers, the limit is lower (commonly 0.04%), so 0.08% is not the limit for those drivers. For under-21 drivers, many places have zero tolerance or a much lower limit.
