Alaska CDL Practice Test

The Alaska DMV gives 80% as the passing score for every CDL knowledge test, and its hazmat page describes a 30-question hazmat test. It doesn’t list the other sizes; our practice tests use the usual format: General Knowledge 50 (40 to pass), Air Brakes 25 (20), and Combination, Tank, Doubles/Triples, Passenger and School Bus 20 each (16). Alaska Commercial Driver License Manual p. 2

The Alaska Commercial Driver License Manual (AAMVA version July 2017, revised by the Alaska DMV 02/2018): Alaska’s own pages on who needs a CDL, testing, medical cards, implied consent, endorsements and restrictions, then inspection, safe driving, cargo, passengers, air brakes, combination vehicles, doubles and triples, tankers, hazmat and school buses. Alaska Commercial Driver License Manual p. 1 to 10-11

Knowledge tests may be taken once per day until you pass. A second road skills test can be given at least a week after the first, if the department finds it necessary. Alaska Commercial Driver License Manual p. 2

The commercial knowledge test, plus Combination for a Class IA (Class A) permit and Air Brakes unless you accept the L restriction. If you are new to Alaska, have come back, or your Alaska license expired over a year ago, you also take the regular driver general knowledge test. A CDL vision test replaces a medical certificate you don't submit.

80% on each of the 8 tests, each graded on its own (General Knowledge: 40 of 50). Every test's numbers are in the table on this page. Always confirm the current tests with the Alaska Department of Administration, Division of Motor Vehicles (DMV). Why 80% in every state →

Be at least 18 (21 for interstate driving, hazmat or school bus), an Alaska resident with a valid Alaska license, lawful status, a Social Security number and a medical examiner’s certificate unless exempt. Pass the knowledge tests for a CLP, hold it at least 14 days, complete ELDT and pass the skills tests in a representative vehicle.

In 14 listed communities that lack testing infrastructure (Bethel, Prince of Wales Island, Haines, Ketchikan, King Salmon, Kodiak Island, Kotzebue, Nome, Mitkof Island, Sitka, Skagway, Unalaska Island, Utqiagvik and Wrangell Island), FMCSA’s exemption lets the DMV waive the parts of the skills test that can’t be done, with no ELDT; the CDL carries restriction 8 and is valid only there. Restriction 7 (off-highway) licenses are valid only in their own communities.

Alaska Department of Administration, Division of Motor Vehicles (DMV) lists the current fees for the commercial learner permit, the CDL tests and the license on its official fee page.

Alaska gives permits their own class names. IA is the permit for Class A combination vehicles, IB for Class B heavy straight vehicles such as dump trucks and motor coaches, and IC for Class C small vehicles that carry 16 or more people or placarded hazmat.

A licensed driver sitting beside you who is at least 21, is licensed for the class and endorsements of the vehicle you are driving, and has held that license for at least a year. With a CLP you may drive only vehicles of your permit class or smaller.

180 days from the day you get the permit. If you need more time, you can submit your forms again to extend it for another 180 days, but Alaska allows that extension only once.

Not for seasonal work: a valid CDL from your home state is enough. If you plan to stay, you must get an Alaska CDL within 30 days of moving. Transferring drivers also pass Alaska's regular general knowledge test, and the motorcycle knowledge test too if their license includes motorcycles.

Two of its own besides the national letters: 7 for drivers living in off-highway communities, and 8 for drivers in the 14 communities covered by Alaska's CDL waiver. Each limits where the license can be used for commercial driving.

Age 21, eligibility for a Class A, B or C CDL, lawful status, a TSA background check, ELDT before your first hazmat knowledge test, and the 30-question hazmat test.

Age 21, at least three years of driving experience, ELDT for a first S endorsement, a state and FBI background check, a Department of Education approved school bus course, and the general knowledge, passenger, school bus and (unless restricted) air brake tests plus a road skills test in a representative bus.

Renew as usual and add a new medical card, the school bus application (Form 412), a new fingerprint background check and a vision retest. Expired over a year: retake the knowledge test. Over two years: a new Department of Education training certificate. Over five years: start again as a new applicant, except ELDT.

Serious crimes such as homicide, sexual assault, kidnapping, felony DUI or felony drug distribution bar you for life. A misdemeanor DUI or test refusal, reckless endangerment or fourth-degree assault bars you for 2 years. DUI or refusal in a commercial vehicle, leaving an accident scene, or two misdemeanor DUIs bar you for 10 years.

It has its own date on the back of the CDL, set by your TSA threat assessment or TWIC card and usually no more than 5 years away; the CDL itself generally lasts 8 years. Alaska mails a reminder at least 60 days ahead. Renewing a CDL within a year of expiry can keep the old hazmat date.

Yes. The 30-question hazmat test is taken at first issue, at every renewal and when you transfer the endorsement. Bring a valid TWIC or a TSA assessment less than 6 months old. Transferring drivers who had hazmat elsewhere show that state's CDL or driving record, or may give the endorsement up and keep the rest.

Carry your medical examiner’s certificate when you drive a CMV (unless your self-certified type of operation is excepted). The state must downgrade a CDL whose medical certificate on file has expired within 60 days of expiration. Alaska Commercial Driver License Manual p. 2

Only if you don't meet the federal CDL requirements, for example because you are under 21 or blind in one eye. Choosing either intrastate type puts the K restriction on your CDL. Both non-excepted types need a current medical certificate, filed with the DMV and carried while you drive.

Only to holders of an H-2A, H-2B or E-2 visa with a valid foreign passport, checked with USCIS before every issue or renewal. Since September 29, 2025 an EAD card no longer qualifies, and Canadian and Mexican citizens aren’t eligible. The license ends on the “admit until” date, after one year, or when lawful status ends, whichever comes first.

Yes, with the 416E waiver, if you serve now or left within a year and drove a CMV-like military vehicle in a listed job for the past year, with a clean one-year record and your commanding officer's signature. It doesn't cover the H, P or S endorsements.

Yes, with the 416S waiver, which also skips ELDT, if you drove a CMV-like military vehicle for the past two years and have a two-year good driving record, certified by your commanding officer. You still pass the knowledge tests or add the 416E waiver. Hazmat, passenger and school bus endorsements aren't included.

People living in a community off the road system, with no DMV services and no skills test offered at least once a year. They meet every other CDL requirement but skip the road test and ELDT, and get restriction 7. Alaska says it is the only state allowed to issue off-highway CDLs.

Book a road test at a DMV office or a driving school and pass it. To lift restriction 8 for an unrestricted CDL on the road system, you must first complete the full Entry-Level Driver Training that the rural exemption let you skip.

Under the current federal rule, at least 180 days for a first violation (up to 2 years with hazmat or passengers), at least 2 years for a second in ten years and 3 years for a third. The manual’s AAMVA text still prints older figures.
