CDL Requirements in Wisconsin

Wisconsin DOT's Division of Motor Vehicles (DMV) issues CDLs on an 8-year cycle bundled with the underlying Class D license, and its knowledge tests are entirely free — DMV charges only for the license/permit issuance itself and for the road/skills tests. Wisconsin calls FMCSA's four self-certification categories 'Tiers of Operation' (Tier 1-4) and requires every commercial driver to file a dedicated tier-certification form (MV3230) in person, separate from the CDL application itself.
Wisconsin's CDL requirements — including a $30 commercial learner permit fee and an intrastate minimum age of 18 — are verified against Wisconsin Department of Transportation, Division of Motor Vehicles (DMV) (see Wisconsin DOT DMV — Commercial Driver License (CDL) Requirements), current as of 2026-07-25.

Valid 180 days and renewable. Applicant must hold a valid Class D license, pass the applicable knowledge test(s), and hold the CLP 14 days before taking a road/skills test. A CLP holder under 21 without a federal medical card is restricted to intrastate-only (or intrastate excepted-industry) operation.
A CLP or CDL holder under 21 may not operate in interstate commerce and is restricted to intrastate operation until 21, matching the federal floor exactly; Wisconsin states this explicitly as a CLP condition rather than leaving it implicit.
All CDL knowledge tests are free, walk-in (no appointment needed), and take roughly 1-1.5 hours; a passing score is 80%+ and an applicant need only retake the section(s) failed. Skills tests are performed by DOT-authorized third-party examiners under a state fee cap ($150 for the full pre-trip/basic-control/road test when done in one sitting, $50 per section if split, $50 for an abbreviated school-bus test) rather than a DMV-set flat price; examiners may charge less. A driver who fails a skills-test component faces a minimum 2-day waiting period before retesting.
Wisconsin CDL Endorsements
| Endorsement | Available | Fee | Knowledge test | Skills test |
|---|---|---|---|---|
| Hazardous materials (H) | Yes | $67.25 | Yes | No |
| Tank vehicle (N) | Yes | — | Yes | No |
| Doubles/triples (T) | Yes | — | Yes | No |
| Passenger (P) | Yes | — | Yes | Yes |
| School bus (S) | Yes | $10 | Yes | Yes |
Hazardous materials: Fee is $57.25 if done together with a CDL renewal; a separate $23.75 fingerprinting fee is paid directly to Wisconsin's designated vendor, Fieldprint, not to DMV. A first-time H applicant must be fingerprinted at a Fieldprint location within 7 days of passing the H knowledge test.
Tank vehicle: Tank Vehicles Knowledge Test; DMV's fee pages do not itemize a separate dollar fee beyond the standard class/endorsement issuance fees.
Doubles/triples: Doubles and Triples Knowledge Test; DMV's fee pages do not itemize a separate dollar fee beyond the standard class/endorsement issuance fees.
Passenger: Passenger Transport Knowledge Test plus a driving skills test performed in a 'Passenger Bus' type vehicle when originally issued.
School bus: Fee is $10 when adding S for the first time, or $5 (plus the underlying CDL fee) when renewing an existing S or transferring one from another state. Requires a knowledge test, road-signs test, vision test, and skills test performed in a school-bus-type vehicle at both original issuance and every renewal. A criminal-history background check runs at original issuance, each renewal, duplicate issuance, and every 4 years; fingerprinting is required only for applicants who have lived in another state within the past two years.

Federal requirements that apply in Wisconsin
These are set by federal regulators and are the same in every US jurisdiction. Full detail here.
- Entry-Level Driver Training (ELDT). Since February 2022, first-time CDL applicants — and drivers upgrading to Class A or seeking a first-time school bus, passenger, or hazmat endorsement — must complete Entry-Level Driver Training with a provider on the FMCSA Training Provider Registry before testing.
- DOT medical certificate. Most CDL holders who operate in interstate commerce must hold a valid DOT medical examiner's certificate, issued by an examiner listed on the FMCSA National Registry of Certified Medical Examiners.
- Interstate minimum age. Federal rules set 21 as the minimum age to drive commercially across state lines; states set their own intrastate minimum, commonly 18.
- Hazmat security threat assessment. A hazardous materials endorsement additionally requires a TSA security threat assessment, which is a federal process separate from the state endorsement.
Self-certification in Wisconsin
Wisconsin Department of Transportation, Division of Motor Vehicles (DMV) administers self-certification for the following FMCSA operating categories:
- Non-Excepted Interstate
- Excepted Interstate
- Non-Excepted Intrastate
- Excepted Intrastate
Wisconsin brands the four FMCSA categories as 'Tiers of Operation': Tier 1 (NI), Tier 2 (EI), Tier 3 (NA), Tier 4 (EA). All commercial drivers must certify their tier in person on Form MV3230; any change in tier requires paying for a duplicate CDL, and Tier 1/3 (non-excepted) drivers without a valid medical certificate on file have their CDL classes/endorsements surrendered until one is reported.
