How does the BAC limit for those under 21 compare to the legal limit for those 21 and older?

The blood alcohol concentration (BAC) limit for individuals under 21 is lower than the legal limit for those who are 21 and older, which is why this answer is correct. In many states, including North Dakota, the BAC limit for drivers under 21 is set at 0.00% or sometimes 0.02%, reflecting a zero-tolerance policy. This is intended to discourage underage drinking and driving, as they are not legally permitted to consume alcohol.

In contrast, the legal BAC limit for adults 21 and over is typically 0.08%. This difference in limits highlights the responsibility placed on younger drivers to avoid any alcohol consumption altogether, recognizing the increased risks associated with underage drinking.
