CDL Requirements in Iowa (2026): Steps, Cost & Testing

Source review dated October 12, 2026 against Iowa Department of Transportation (Iowa DOT), Motor Vehicle Division

Iowa issues CDLs through the Iowa Department of Transportation (Iowa DOT), Motor Vehicle Division. You hold a regular Iowa license, pass the knowledge tests for a $12 Commercial Learner's Permit, hold it at least 14 days while completing ELDT, then pass a three-part skills test in a vehicle you supply — at an Iowa DOT/county treasurer site or a DOT-authorized third-party tester. The CDL fee is $8 per year of validity (up to $64 for an 8-year license).

This guide combines federal rules with dated state research. Read the review notes before paying fees or booking a test.

Iowa's state fees are among the lowest in the country and are set by statute — $12 for the CLP and $8 per year of validity for the CDL (about $64 for an eight-year license), with endorsements of $5 to $10. The real costs are ELDT tuition, a DOT physical, any third-party testing-site fee, and — for hazmat — the separate TSA background check.

A few Iowa specifics: you can test at Iowa DOT service centers, participating county treasurer offices, or DOT-authorized third-party testers; qualifying service members can skip the skills test, and some can also have the knowledge test waived; and because Iowa is not a TSA self-managed state, hazmat fingerprinting runs through the standard TSA/IDEMIA enrollment process rather than the DOT.

Eligibility and documents in Iowa

• Age: at least 18 for intrastate driving; 21 to drive interstate or haul hazmat.
• Proof of full legal name and date of birth (e.g., certified U.S. birth certificate or valid U.S. passport)
• Proof of Social Security number
• Proof of U.S. citizenship, lawful permanent residency, or an EAD/I-94 for eligible non-citizens
• Proof of Iowa residency (a current Iowa driver's license showing your Iowa address satisfies this)
• A valid Iowa driver's license (the CLP/CDL builds on it)
• Medical self-certification of your operating category, plus a Medical Examiner's Certificate on file if your category requires one (now transmitted electronically by the examiner)
• Vision screening

How to get your CDL: step by step

1. 1

   Check eligibility, documents, and medical qualification

   Choose the CDL class and endorsements for your vehicle. Hold the required regular license and bring Iowa identity, residency, and Social Security documents. Self-certify your operating category and complete a DOT physical before the permit if that category requires medical certification.

2. 2

   Pass the knowledge tests and obtain your CLP

   Take general knowledge and the vehicle/endorsement tests that apply. ELDT theory may be taken earlier, but federal rules do not require it before the CLP. A first-time hazmat applicant must complete hazmat theory before the hazmat knowledge test; hazmat is not issued on a CLP.

3. 3

   Complete required training and practice during the permit hold

   Hold the CLP for at least 14 days before the skills test. Use a qualified supervising driver for public-road practice. First-time Class A/B, B-to-A upgrades, and first-time P/S endorsements require applicable theory and behind-the-wheel ELDT from registered providers. The appropriate CLP is needed for public-road training. State training requirements may add to the federal baseline.

4. 4

   Pass the skills test in the right vehicle

   Confirm ELDT completion is recorded, arrange the test and a representative vehicle, then complete vehicle inspection, basic control, and road driving. The vehicle and transmission you test in can restrict your license.

5. 5

   Complete issuance and maintain your qualifications

   Pay the applicable Iowa issuance fees and confirm the correct class, endorsements, restrictions, and expiration. Keep your medical status current when required and follow the agency’s renewal instructions.

Medical certification in Iowa

Self-certify your operating category when you apply for a CLP, initial CDL, transfer, renewal, upgrade or duplicate (the form may be electronic; current holders can use the Iowa DOT MyMVD portal). Under 761 IAC 607.23, a driver who self-certifies to non-excepted interstate driving must give the department a copy of the current medical examiner's certificate unless FMCSA provides it electronically; with the National Registry II electronic transmission from your certified medical examiner, the FMCSA data supersedes any paper copy.

If your card lapses: Keep your self-certification and, if applicable, your medical examiner's certificate current. If a required certificate or variance expires, Iowa posts 'not certified' and removes commercial privileges (downgrade) 60 days after the expiration unless a current certificate is received or you self-certify to a category other than non-excepted interstate.

Every CDL holder must self-certify one operating category. The categories offered here:

• NI — Non-excepted Interstate (Medical Examiner's Certificate required)
• EI — Excepted Interstate (no card; operations limited)
• NA — Non-excepted Intrastate (card required; adds a 'K' intrastate restriction)
• EA — Excepted Intrastate

What a CDL costs in Iowa

These are separate transaction types, not charges that every applicant pays. Renewal, replacement, endorsement, and retest fees are alternatives or extras. Amounts are from the dated research; check current official fees before paying.

Iowa's state fees are low — the $12 CLP and $8/year CDL are set by statute. The bigger costs are ELDT tuition, third-party testing-site fees (rough planning estimates, not published by Iowa DOT), a DOT physical (estimated ~$79–$150), and, for hazmat, the TSA Security Threat Assessment fee (estimated at roughly $85 via IDEMIA — confirm current amount with TSA/IDEMIA, not the DOT).

See the full national breakdown on our CDL cost guide.

Skills testing in Iowa

Testing access: State / approved third parties. Official testing instructions.

Iowa allows approved third-party testers to administer the CDL skills test, with availability and fees set by the provider. Iowa DOT does not publish official wait times; availability varies by site. Some third-party testers can't schedule until at least three business days after registration to allow DMV-system entry. Using a school that bundles testing, or a third-party tester, often shortens the wait.

Your test vehicle: You must supply a vehicle that is validly registered, in good working order, and representative of the class of license you're applying for; the state does not provide a test vehicle.

Endorsements available in Iowa

Iowa offers the standard federal endorsements. Adding one usually means an extra knowledge test (and a skills test for passenger and school bus). Tap an endorsement for the full federal process and cost:

• HHazmat — Iowa is NOT a TSA self-managed state. You pass the 30-question hazmat knowledge test (ELDT theory required for first-timers) at a testing site AND complete the standard TSA Security Threat Assessment — fingerprinting/background check enrolled through TSA's vendor (IDEMIA/Universal Enroll, a.k.a. IdentoGO), not the DOT. Start the HME application (HazPrint help desk 855-347-8371) before fingerprinting; results typically take about 30-45 days. State endorsement fee is $5; the TSA background-check fee is separate. Renews on the TSA 5-year cycle.
• NTanker — Tank vehicle endorsement; $5 state fee.
• XHazmat + Tank — Combined hazmat + tank; the TSA background check and 5-year hazmat cycle apply.
• PPassenger — Passenger endorsement; $10 state fee. Requires passenger knowledge and skills tests, and ELDT for first-timers.
• SSchool Bus — School bus endorsement; $10 state fee. Requires the P (passenger) endorsement basis plus S knowledge and skills tests, and ELDT for first-timers.
• TDoubles/Triples — Double/triple trailers; $5 state fee. Knowledge test only (no separate skills test).

CDL disqualifications

Disqualifying offenses are set by federal law (49 CFR 383.51) and apply in every state. Some also apply in a personal vehicle; vehicle-specific conditions matter. Iowa applies the federal 49 CFR 383.51 disqualification framework through Iowa Code Chapter 321 (see §321.208 and related sections), including the major-offense and lifetime disqualifications. No material Iowa-only additions beyond the federal baseline were confirmed; reinstatement of commercial driving privileges after a disqualification carries a $20 fee (Iowa Code 321.191(8)).

The offenses that trigger a disqualification, the length of each, and the federal exceptions are listed once in our CDL disqualifications guide instead of repeating the table here. Check the review notes for any Iowa-specific additions we could not confirm.

Military skills-test waiver

Check the temporary July 30–October 29, 2026 federal eligibility extension and ask the state whether it participates.

Iowa may waive the CDL skills test for an applicant who is on active duty or separated from military service in the past year and who meets Iowa Code 321.188(6) (761 IAC 607.13(6)): same-class commercial-type vehicle experience, no more than one license other than a military license, no suspension/revocation, and no disqualifying or serious-violation convictions in the prior two years. Iowa may separately waive the knowledge test for current or former service members in the military positions designated in 49 CFR 383.77 with a DD Form 214 showing honorable separation (761 IAC 607.12(5)). Contact Iowa DOT for the current application form.
