For minors, what is the BAC limit before they are considered under the influence of alcohol?

In Montana, for drivers under the legal drinking age of 21, the blood alcohol concentration (BAC) limit to be considered under the influence is set at 0.02%. This lower threshold recognizes that any amount of alcohol can impair a minor's abilities and judgment while driving. The state has stringent laws to discourage underage drinking and driving, promoting safety and reducing the risks associated with alcohol consumption for inexperienced drivers.

The option of 0.00% represents a zero-tolerance policy, which some might consider, but the legal limit for minors specifically allows for a small permissible amount, establishing the 0.02% threshold. This helps differentiate between legal adults and minors in the context of alcohol consumption when operating a vehicle. The higher limits of 0.05% and 0.08% apply to adult drivers, reflecting a more lenient approach as adult drivers may have different considerations regarding alcohol and driving capability based on their greater experience.
