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

Requirements verified July 20, 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 about $64 for an 8-year license).

Iowa runs its CDL program through the Iowa Department of Transportation's Motor Vehicle Division. The path follows the federal pattern: hold a regular Iowa license, pass the knowledge tests for a $12 Commercial Learner's Permit, complete ELDT through the FMCSA Training Provider Registry, hold the permit at least 14 days, then pass a three-part skills test (pre-trip inspection, basic control, and a road test) in a vehicle you supply.

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 veterans can skip the skills test (but not the written test); 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. Get your Commercial Learner's Permit (CLP). Pass the required knowledge tests: General Knowledge (all applicants); Combination Vehicles (Class A); Air Brakes (if your vehicle has them); Any endorsement tests you need (P, S, H, N, T).
2. Complete ELDT training. For a first Class A/B CDL or a first hazmat, passenger, or school-bus endorsement, you must train with a provider on the FMCSA Training Provider Registry. Iowa DOT (and its testing sites) checks the federal FMCSA Training Provider Registry to confirm you completed ELDT with a listed provider before administering the CDL skills test, and before the hazmat knowledge test. Iowa uses no separate state ELDT portal — you find providers on the federal registry. ELDT is not required just to get a CLP. Drivers who held the relevant CDL or endorsement before February 7, 2022 are grandfathered. First-time hazmat applicants must complete ELDT theory training before taking the hazmat knowledge test.
3. Hold your permit 14 days. Federal rules require at least 14 days before the skills test.
4. Pass the skills test. It has 3 parts: Pre-trip vehicle inspection, Basic vehicle control skills, On-road driving test. Iowa administers CDL skills tests at Iowa DOT driver's license service centers and participating county treasurer sites, and through DOT-authorized third-party testers (community colleges and private schools such as Kirkwood and Western Iowa Tech). Third-party tests are identical to state tests but may require class enrollment and carry their own fees. Iowa DOT publishes a statewide CDL testing-locations list.
5. Get your CDL issued. Pay the license fee, submit your medical self-certification, and receive your license (valid 8 years). Iowa CDLs are issued for up to 8 years for applicants age 18-72, with the term shortening for older drivers (down to 2 years at 78+). Within the qualifying range Iowa's system randomly assigns a 5-, 6-, 7-, or 8-year term to level out renewal volume. Upgrading class (e.g., B to A) requires a new CLP, the applicable knowledge/skills tests, ELDT if first-time, and a 14-day hold; upgrade fees are prorated on full-year increments. 100%-disabled veterans and active-duty/honorably-discharged service members may qualify for a waiver of the CDL fee under Iowa Code 321.191(10).

Medical certification in Iowa

Self-certify your operating category when you first obtain, renew, or upgrade a CDL — current holders can self-certify online through the Iowa DOT MyMVD portal (mymvd.iowadot.gov). Since the June 23, 2025 federal National Registry II (NRII) rule, your certified medical examiner transmits your exam results to the state electronically through the National Registry — non-excepted drivers no longer hand in the paper card.

If your card lapses: Keep your self-certification and, if applicable, your Medical Examiner's Certificate current. If a required medical card lapses, Iowa downgrades your CDL to a non-commercial license until a valid card is on file again.

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

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 (surveyed market data, not published by Iowa DOT), a DOT physical (surveyed ~$79–$150), and, for hazmat, the TSA Security Threat Assessment fee (surveyed 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 Third-party testing allowed

Iowa allows approved third-party testers to administer the CDL skills test, which can mean shorter waits than a state office. 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 — including offenses in your personal vehicle. 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)).

Full federal detail: CDL disqualifications explained.

Military skills-test waiver

Iowa waives the CDL skills (drive) test for qualifying service members via the Application for Military Skills Test Waiver (Iowa DOT form 493003). You must be on active duty or within one year of separation, an Iowa resident with a valid Iowa license, and have legally operated the same class of commercial vehicle for at least two years, with a clean recent record (no more than one civilian license and no disqualifying convictions/sanctions). The written knowledge test is NOT waived.
