What is the presumptive state of impairment for driving in Virginia?

In Virginia, the legal blood alcohol concentration (BAC) limit that serves as the presumptive state of impairment for driving is 0.08. This means that if a driver's BAC measures at or above this level, they are presumed to be impaired and can be charged with driving under the influence (DUI). This standard is based on research that demonstrates that a BAC of 0.08 significantly increases the risk of being involved in a crash and impairs a person's ability to operate a vehicle safely.

This legal threshold applies to individuals aged 21 and over. Drivers under this age face stricter limits, as any measurable amount of alcohol can lead to penalties. Knowing the presumptive BAC limit is crucial for safe driving practices and understanding the legal implications of alcohol consumption.
