What is the legal blood alcohol content (BAC) limit for drivers aged 21 or older to avoid DUI charges?

The legal blood alcohol content (BAC) limit for drivers aged 21 or older in Virginia is .08 percent. This standard is widely recognized across many states in the U.S. and serves as a clear threshold for determining whether a driver is legally impaired. If a driver's BAC is at or above this limit, they can be charged with driving under the influence (DUI). This limit is set to enhance road safety by reducing the risk of accidents associated with alcohol consumption.

A BAC of .05 percent may still impair a driver's ability to operate a vehicle safely, but it is below the threshold for DUI charges in Virginia. A BAC of .10 percent is above the legal limit, and while there was a time when this was seen in different jurisdictions, it is not applicable in Virginia for drivers aged 21 and older. The statement that there is no limit is inaccurate, as having a measurable BAC is enough for DUI charges if it exceeds the legal limit. Hence, a BAC of .08 percent or higher is the standard that must be adhered to in order to avoid DUI charges for adults.
