Your license can be suspended if you are under 21 and drive with a blood alcohol level of:

  1. 0.15 percent or more.
  2. 0.08 percent or more.
  3. Any amount. ✓

Answer: C. Any amount.

Any amount is the correct choice: for a driver under 21, the handbook’s under-21 alcohol rule starts at a BAC of 0.01% or higher, not at the higher levels.

Why this is the answer

The under-21 section says that if you are convicted of a DUI with a BAC of 0.01% or higher, DMV may revoke your driving privilege for one year, and you must complete a licensed DUI program. That is a near-zero standard. Because the question is about a driver under 21, the answer is the choice that treats any alcohol as enough to trigger the under-21 rule, rather than waiting for 0.08 or 0.15 percent.

Why the other answers are wrong

Remember it

For a driver under 21, think near-zero: the handbook’s under-21 DUI threshold starts at 0.01%, not at the adult numbers.
