What is the legal blood-alcohol limit for driving?

The legal blood-alcohol limit for driving is established to promote road safety and reduce alcohol-related accidents. A blood-alcohol concentration (BAC) of 0.08 grams per 100 milliliters is widely recognized and enforced across many jurisdictions as the threshold at which a driver is considered legally impaired.

Above this limit, individuals may experience diminished judgment, slower reaction times, and impaired coordination, which significantly increases the risk of being involved in a traffic accident. Numerous studies and data support this threshold, demonstrating that driving with a BAC at or above 0.08 leads to a higher likelihood of crashes, injuries, and fatalities.

Consequently, law enforcement and legal systems utilize this standard to prosecute impaired driving offenses, thus making it an essential factor in traffic laws aimed at protecting public safety.
