What is the legal Blood Alcohol Concentration (BAC) limit for drivers over 21?

The legal Blood Alcohol Concentration (BAC) limit for drivers over 21 in New Jersey is .08. This means that if a driver's BAC is at or above this level, they are considered legally impaired and can be charged with driving under the influence (DUI). This standard is established to promote road safety by discouraging alcohol consumption before driving, as even small amounts of alcohol can significantly impair a person's ability to operate a vehicle safely.

The importance of the .08 limit lies in its role in protecting both the driver and the public. At this level, a driver's judgment, coordination, and reaction time are noticeably affected, increasing the risk of accidents. Consequently, law enforcement and policy-makers have set this limit to ensure that drivers who are sober and responsible can safely share the road with others.
