California Driver License (DMV) Written Practice Test

In California, it is illegal for individuals under the age of 21 to have any alcohol in their system while driving. This means that the legal blood alcohol content (BAC) limit for individuals under 21 is 0.00, making all of the other options incorrect. Option B (0.05) is the legal BAC limit for driving in California for individuals 21 and older who are not commercial drivers. Option C (0.08) is the BAC limit for commercial drivers in California. Option D (0.10) is not a legal BAC limit in California and could result in a DUI charge. It is important to always follow the laws and never drink and drive. Remember, even small amounts of alcohol can impair your ability to drive safely, so it is best to avoid drinking any alcohol before getting behind the wheel.
