Final answer:
The zero tolerance policy for individuals under 21 enforces a BAC limit as low as 0.01%, which can lead to license revocation. This is much lower than the general 0.08% BAC legal limit for those above the legal alcohal consumption age.
Step-by-step explanation:
Zero Tolerance Policy and BAC Limits
The zero tolerance policy for alcohal consumption and driving sets a very strict limit on blood alcohol concentration (BAC) for individuals under the age of 21. If you are under 21, the zero tolerance policy states that your license can be revoked even if your BAC is as low as 0.01%. This threshold is significantly lower than the 0.08% BAC limit set for those above the legal alcohal consumption age.
It's important to understand that when it comes to driving under the influence, each state has the authority to enforce these limits differently. However, due to the influence of the National Minimum alcohal consumption Age Act of 1984, all states comply with the federal mandate to have a minimum alcohal consumption age of 21 and adopt zero tolerance laws for minors to avoid a reduction in federal highway funds.
The main aim of the zero tolerance policy is to discourage underage alcohal consumption and driving, as alcohol impairs critical skills and judgment required for safe driving. (MADD), among other organizations, has been a staunch advocate for such policies to protect young Americans from the dangers of impaired driving.
