What BAC level is illegal for drivers under 21?

For drivers under 21, any amount of alcohol in the bloodstream is illegal to drive. This is a zero-tolerance rule, so the cutoff is very low: 0.01% BAC or higher means illegal driving for someone under 21. The other levels listed—0.05% or higher, 0.08% or higher, and 0.03% or higher—are thresholds that apply to adult drivers or in other contexts, not the under-21 zero-tolerance standard. So even a small amount of alcohol can lead to consequences for someone under 21, which is why 0.01% or higher is the correct understanding.
