Idaho Class A CDL Practice Questions

This Idaho Class A CDL practice page is built around the 100-question bank saved for this run. It covers general commercial-driving knowledge, air brakes, combination vehicles, hazardous materials, tank vehicles, and doubles/triples scenarios. The specialty modules are conditional: a Class A license does not automatically grant every endorsement or mean every applicant takes every specialty test. Idaho defines Class A as a qualifying combination with a gross combination weight rating of 26,001 pounds or more when the towed vehicle has a GVWR over 10,000 pounds. Idaho applicants must meet the State's CDL eligibility path, obtain the required commercial learner's permit, complete applicable knowledge testing, hold the CLP for at least 14 days before the skills test, and satisfy federal Entry-Level Driver Training when the rule applies to a first-time Class A applicant.

LICENSING GUIDE

What to know before you test

Use this overview together with the latest official guidance linked below.

Confirm Idaho Class A eligibility before testing

Idaho's current CDL page says an applicant must be at least 18 years old and must either hold a valid Idaho non-commercial Class D license or have passed all tests required to obtain one. Idaho also requires one year of licensed driving experience before CDL issuance. Class A applies to a combination with a GCWR of at least 26,001 pounds when the towed vehicle's GVWR is over 10,000 pounds. A Class A holder may operate vehicles requiring lower classes when the driver also has any endorsements required for that operation.

Bring the required identity and residency documentation

Idaho's CDL guidance requires proof of lawful presence and current proof of Idaho residency before a CDL can be issued. Idaho's credential-document guidance also explains that the DMV verifies identity and age, citizenship or lawful presence, Idaho residency, and legal name as applicable, with Social Security number information electronically verified at issuance. Medical certification requirements depend on the driver's self-certification category and applicable federal or state rules, so applicants should review the current CDL and medical-certification instructions before visiting the county DMV office.

Pass the knowledge tests and obtain the CLP

Idaho instructs applicants to pass the applicable CDL knowledge tests before the skills test can be administered. For Class A, that normally includes general knowledge and combination-vehicle knowledge, with air-brake or endorsement tests added when the equipment or operation requires them. After the required knowledge testing, the applicant obtains a commercial learner's permit. Idaho says the CLP is valid for one year, and federal and Idaho guidance require it to be held for at least 14 days before the CDL skills test.

Complete applicable ELDT and the Class A skills test

Federal ELDT rules apply to a first-time Class A applicant unless an exception applies. Required training must be completed through a provider listed on the FMCSA Training Provider Registry before the State may administer the applicable CDL skills test. Idaho's CDL testing materials describe three skills-test parts: vehicle inspection, basic control skills, and the road test. Applicants should test in a representative Class A combination and with the equipment needed for the privileges they want, because the vehicle used for testing can affect restrictions on the resulting CDL.

Idaho defines Class A as a combination with a GCWR of 26,001 pounds or more when the GVWR of the towed vehicle exceeds 10,000 pounds. Endorsement and equipment requirements depend on the actual vehicle and operation; Class A status alone does not provide every specialty endorsement.
