What is the legal BAC limit for drivers aged 21 or older to avoid being charged with DUI?

In Virginia, the legal blood alcohol content (BAC) limit for drivers aged 21 or older is established at 0.08 percent. This means that a driver whose BAC measures at or above this level can be charged with driving under the influence (DUI). The significance of this limit is rooted in research and statistics indicating that impairment begins to increase noticeably at this level, affecting a person's ability to operate a vehicle safely.

Drivers should be aware that even below this threshold, any measurable amount of alcohol can still impair driving abilities, and individuals may still face penalties if their driving is deemed unsafe. This legal limit acts as a clear guideline for law enforcement and the judicial system regarding permissible levels of alcohol consumption while driving.
