What is the zero tolerance law when driving?
Zero-tolerance laws set a blood alcohol concentration (BAC) of .00 or .02 at which it is against the law to drive. There is no margin of error for a BAC above what is stated in their zero-tolerance legislation. This law usually applies to minors or new drivers to deter them from underage drinking and driving under the influence. Even a small amount of alcohol is considered illegal for these individuals or groups to consume if operating a vehicle. These laws serve as effective preventive measures to help ensure road safety in these demographic groups.
