Final answer:
License suspension periods can vary by state, but often a license is administratively suspended as soon as 7 days after an arrest for a DUI where the breathalyzer test shows a BAC of .08 or higher, or .02 or higher if under the age of 21.
Step-by-step explanation:
If it is your first arrest within seven years and your breath or breath test result shows a BAC of .08 or more (.02 if you are under the age of 21), the specifics of the license suspension period may vary by state. However, after an arrest for driving under the influence, there is often an immediate administrative license suspension before any court action takes place. For instance, in some states, this administrative suspension can occur as soon as 7 days after the arrest if you fail a breathalyzer test. It's crucial to check the specific laws in your state as procedures can differ. The National Minimum Drinking Age Act of 1984 mandated states to enforce a minimum drinking age of twenty-one, which is also related to the legalities surrounding driving under the influence offenses for those under 21 with a BAC of .02 or higher.
