If you are under 21, what is the lawful BAC for a driver?

0.00%
0.08%
0.10%
0.05%

The correct answer is: 0.00%

Generally, the legal blood alcohol concentration (BAC) limit for drivers under the age of 21 in most states is 0.00%. This means that any amount of alcohol in their system while operating a vehicle is considered illegal and can result in consequences such as a suspended license. Options B, C, and D all have a percentage of allowed BAC, meaning that any amount below that percentage may be deemed legal. However, for underage drivers, even a small amount of alcohol in their system can have severe consequences. It is important for young drivers to understand and abide by the zero tolerance policy for driving under the influence.
