How the test works
You can take it online and then contact the DMV to say you passed, so they can update your record. After that you can renew online. You can also take it at a local DMV office. Alaska has no grace period once a license expires, and driving on an expired license is illegal, so don’t leave it until day 90.
Online, the test runs on the same KnowTo Drive system as the permit test. Its FAQ says you must be at least 20 to take the alcohol test online, and each attempt costs $11.50, as of October 2026.
How to study for it
The test is about how alcohol and drugs affect your driving and what Alaska’s DUI laws say. Everything you need is in the alcohol and drugs section of the Alaska Driver Manual: the 0.08 limit, the zero-alcohol rule under 21, implied consent, revocation periods and ignition interlocks.
We couldn’t find a separate official practice test for the alcohol test. Our free permit practice test includes alcohol and DUI questions in the same style, so it’s a quick way to check what you remember.
