As a driver under the age of 21, your maximum legal BAC (zero tolerance) is: less than .02 less than .05 less than .07 less than .08

The correct answer to the question about the maximum legal Blood Alcohol Concentration (BAC) for drivers under the age of 21 is less than .02.

Explanation:

In many jurisdictions, a zero-tolerance policy is enforced for underage drinking and driving. This means that even a small amount of alcohol in the blood can lead to penalties. A BAC of less than .02 is often the limit because it is difficult to measure alcohol consumption accurately, and anything lower than this level is generally considered to reflect a lack of impairment.

This policy serves to discourage underage drinking and holds young drivers to a higher standard of sobriety compared to adults, who typically have a higher legal limit (often .08 in many areas). Failing to adhere to these laws can result in serious legal repercussions, including license suspension, fines, and even criminal charges. It's crucial for young drivers to understand these limits to ensure their safety and compliance with the law.
