Final Answer:
True. In Virginia, a driver under the age of 21 with a blood alcohol content (BAC) of .02 percent or higher is considered to be driving under the influence (DUI).
Step-by-step explanation:
Virginia, like many other states, imposes stricter alcohol-related driving regulations for individuals under the age of 21. In this context, the legal BAC limit is set at .02 percent, significantly lower than the standard limit for drivers aged 21 and older. This lower threshold is based on the recognition that even small amounts of alcohol can impair the judgment and coordination of younger drivers. The rationale is to deter underage drinking and driving by establishing a clear and stringent standard, reinforcing the commitment to public safety.
The calculation of BAC involves assessing the ratio of alcohol to blood volume. A BAC of .02 percent indicates that there are .02 grams of alcohol per 100 milliliters of blood. While this level might not produce obvious signs of intoxication, it reflects a legal recognition that even trace amounts of alcohol can impact the abilities crucial for safe driving, particularly in less experienced and younger drivers. Enforcing a lower BAC limit for individuals under 21 aligns with a preventative approach to discourage underage drinking and driving, emphasizing the legal consequences associated with any detectable level of alcohol in their system.
The stringent regulations for drivers under 21 are part of a comprehensive strategy to address the unique risks associated with underage drinking and driving. This approach aims to protect not only the young drivers themselves but also others on the road by setting a clear standard that discourages any consumption of alcohol before operating a vehicle.
