For young drivers under the age of 21, they may be facing additional charges for consuming alcohol. Some states consider the legal limit to be a BAC of 0.02% for drivers under 21; other states may penalize drivers under 21 who have any amount of alcohol in their blood. DC enforces a zero-tolerance policy for individuals under the age of 21 who have been charged with a DWI. This means you could be charged and subjected to similar penalties even if your BAC level was below .08%. If you’ve been charged with DWI and you’re under 21, it can be even more important to hire a skilled DWI attorney DC provides.
