Checked against official Alaska sources on Oct 8, 2026
Alaska CDL practice test
Every state needs at least 80% on each CDL written test, and Alaska follows the same federal rule. Below are the fees, ages and rules we checked against the official Alaska source, and a free practice test.
FirstTry CDL is not affiliated with any DMV, FMCSA or government agency. Practice questions are exam-style questions built from the official CDL manual, not actual test questions.
Alaska CDL facts
| What | What Alaska says | Source |
|---|---|---|
| Size rule for needing a CDL | You need a CDL when the vehicle or truck and trailer combination is more than 26,000 pounds, when the vehicle is designed to carry 16 or more passengers, or when you transport hazardous materials. | Official page |
| Minimum age | You must be at least 18. You must be 21 for a school bus or hazmat endorsement, or to drive as an interstate driver. | Official page |
| CLP fee | An instruction permit (commercial or non-commercial) costs $15. A permit renewal costs $5. There is no REAL ID version of the permit. | Official page |
| CDL fee | A CDL costs $100 standard or $120 REAL ID compliant. Renewal and off-highway CDLs cost the same. A duplicate CDL is $15 standard or $35 REAL ID. | Official page |
| Commercial road test fee | A commercial vehicle road test costs $25. Road test fees are not refundable. You can reschedule at least 24 hours before your appointment for no fee. | Official page |
| CLP holding period | You must hold a CLP for at least 14 days before your skills test. The CLP must match the class and endorsements of the license you want. | Official page |
| CLP validity | After you get your CLP you have 180 days to schedule and finish your road skills test. You may resubmit your forms to extend the permit another 180 days, but only once. | Official page |
| Knowledge test passing score and retakes | The minimum passing score for all knowledge tests is 80%. Under state rules, knowledge tests may be taken once per day until you pass. | Official page |
| Road skills retest | A second road skills test can be given at least one week after the first if the department decides it is needed. Further testing is at the department's discretion, and it may ask for proof of more driver training. | Official page |
| Knowledge tests for a CLP | The permit page lists the General Knowledge Test (if you are new to Alaska, returned to Alaska, or your license expired more than a year ago), the Commercial Knowledge Test, the Commercial Combination Knowledge Test (Class IA only), the Air Brake Knowledge Test (to remove restriction L) and a CDL vision test if you are not giving a medical examiner certificate. | Official page |
| Permit and license classes | Permit classes are IA, IB and IC for license classes A, B and C. Endorsements are H (hazmat), N (tank), P (passenger), S (school bus), T (doubles and triples) and X (tank and hazmat). | Official page |
| Entry-level driver training | ELDT is required for a first Class A or B CDL, an upgrade to a higher class, or a first hazmat, passenger or school bus endorsement. Hazmat applicants must finish ELDT before the hazmat knowledge test. | Official page |
| Off-highway CDL for remote communities | Alaska says it is the only state allowed to issue an Off-Highway license to commercial drivers. People in communities off the road system with no skills test at least once a year can skip the road test and ELDT, and get a license with restriction 7 or 8. | Official page |
| Residency and Social Security number | You must be an Alaska resident domiciled in the state, show proof of lawful status as a U.S. citizen or permanent resident, and have a valid Social Security Number. | Official page |

| Non-domiciled CDL | Since September 29, 2025, Alaska can only issue a non-domiciled CLP or CDL to holders of H-2A, H-2B or E-2 visas with a valid foreign passport. Canadian and Mexican citizens are not eligible. These credentials last at most one year. | Official page |
