Final answer:
License suspension times after a DUI arrest can vary by state but often begin immediately or shortly after failing a breathalyzer test with a BAC of 0.08 or more.
Step-by-step explanation:
If it is your first arrest within seven years and your breath or breath test result shows a BAC of 0.08 or more (0.02 if you are under the age of 21), the specific number of days after which your license will be suspended can vary depending on the state laws. However, in most cases, administrative penalties like a license suspension typically begin immediately or shortly after the arrest upon failing a breathalyzer test. It's important to consult local DWI/DUI laws for the exact duration, as this falls under the jurisdiction of state law and can be different everywhere.
