What are the legal blood alcohol concentration (BAC) limits for drivers over 21?

The legal blood alcohol concentration (BAC) limit for drivers over 21 years old is set at 0.08%. This standard is established to promote road safety and reduce the risk of accidents caused by impaired driving. When a driver's BAC reaches 0.08% or higher, they are considered legally intoxicated and may face serious penalties, such as fines, license suspension, or even jail time. It is important to understand that this limit serves as a clear indicator of impairment, beyond which an individual's ability to operate a vehicle safely is significantly compromised. The importance of maintaining a BAC below this threshold helps to protect not only the driver but also passengers and other road users.
