How to Obtain a CDL in Iowa

If you're planning to drive a commercial vehicle in Iowa—whether it's a semi-truck, bus, or tanker—you’ll need a Commercial Driver’s License (CDL). The process involves meeting eligibility criteria, passing several tests, and obtaining the proper endorsements for your desired driving classification.

CDL Eligibility Requirements in Iowa

To apply for a CDL in Iowa, you must:

• Be at least 18 years old for intrastate (within Iowa) driving and 21 for interstate (across state lines) driving or transporting hazardous materials.
• Hold a valid, non-commercial Iowa driver’s license.
• Provide proof of U.S. citizenship or lawful permanent residency.
• Have a clean driving record, particularly free from serious traffic violations or DUIs.

The Iowa DOT also requires compliance with medical standards under the Federal Motor Carrier Safety Administration (FMCSA). You must submit a Medical Examiner’s Certificate (DOT physical) unless exempt.

CDL Classifications

There are three main CDL classes in Iowa:

• Class A: Required for combination vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 lbs or more, provided the towed vehicle is over 10,000 lbs.
• Class B: For single vehicles with a GVWR of 26,001 lbs or more, or towing a vehicle less than 10,000 lbs.
• Class C: For vehicles carrying 16 or more passengers (including the driver) or hazardous materials.

Each class may require specific endorsements, which are covered in more detail in Iowa's Commercial Driver's License (CDL) Endorsements.

Steps to Get a CDL in Iowa

1. Obtain a Commercial Learner's Permit (CLP)

   • Pass knowledge tests for the CDL class and endorsements you seek.
   • Provide identity, residency, and Social Security documentation.
   • Hold your CLP for at least 14 days before the skills test.
   • Schedule your tests through the Iowa DOT.

2. Complete Entry-Level Driver Training (ELDT)

   • As of February 2022, all first-time CDL applicants must complete ELDT from a registered training provider listed on the FMCSA Training Provider Registry.

3. Pass the CDL Skills Test
   The skills test includes:

   • Pre-trip inspection

   Testing is conducted at DOT-approved sites. You must provide a vehicle matching the class of CDL you're applying for.

4. Pay Fees and Submit Documentation
