If you are below the age of 21, what is the legal BAC limit to operate a vehicle?

The legal blood alcohol concentration (BAC) limit to operate a vehicle for individuals under the age of 21 is set at a very low threshold of 0.01%. This strict limit is part of the zero-tolerance policies implemented in many jurisdictions to deter underage drinking and driving.

For drivers under 21, even a minimal amount of alcohol can indicate an unacceptable risk on the road, as young and inexperienced drivers may not have the skill level to handle the effects of alcohol, even at low levels. The aim is to promote safety and discourage drinking among young people by enforcing a stringent legal limit that emphasizes the seriousness with which underage drinking is treated in relation to driving.

This approach helps to safeguard not just the young drivers themselves but also all road users by reducing the likelihood of accidents caused by impaired driving.
