What blood alcohol concentration is considered unlawful for driving a vehicle?

0.05
0.08
0.10
0.12

The correct answer is: 0.08

In California, the legal limit for blood alcohol concentration (BAC) when operating a motor vehicle is set at 0.08%. This limit is established to ensure the safety of all road users, as higher levels of intoxication significantly impair a person's ability to drive safely. At a BAC of 0.08%, individuals are more likely to experience decreased motor skills, poor judgment, and slower reaction times, all of which can lead to accidents. While lower levels of BAC, such as 0.05%, may seem less impairing, they still can contribute to a decline in driving performance and increase the risk of accidents. The other BAC levels provided — 0.10% and 0.12% — are higher than the legal limit and indicate more severe impairment. Being aware of this legal threshold is crucial for anyone who may consume alcohol and drive, as exceeding it not only puts their safety at risk but also subjects them to legal penalties.
