You will drive a nonexempt 40,000-pound combination with a trailer rated at 14,000 pounds. Which base CDL class covers this combination?
Correct answer: Class A.
A combination at 26,001 pounds or more falls in Class A when the towed unit exceeds 10,000 pounds. Required endorsements and restrictions still matter.

A nonexempt straight truck has a GVWR of 30,000 pounds and does not tow a trailer. What is the minimum base CDL class for its weight?
Correct answer: Class B.
Class B covers a single vehicle of 26,001 pounds or more. Intrastate operation does not by itself remove the CDL requirement.

A nonexempt bus has a GVWR of 24,000 pounds and is designed for 18 people including its driver. It is nearly empty today. Which licensing conclusion is correct?
Correct answer: It falls within CDL Class C and requires the passenger endorsement.
For this below-Class-B bus, the designed seating capacity—not today's passenger count—triggers Class C passenger licensing.

A nonexempt delivery truck below 26,001 pounds carries a load requiring hazardous-material placards. What is the appropriate licensing conclusion?
Correct answer: Its low weight does not exempt it; Class C and the required hazardous-material endorsement apply.
Required placarding can trigger Class C even when the vehicle is below the weight threshold for Class B. The scenario excludes specific exemptions.

A 19-year-old qualifies for ordinary North Dakota commercial driving and is offered a route crossing into another state. What age boundary applies?
Correct answer: Ordinary drivers ages 18 through 20 are limited to intrastate work; interstate commercial driving requires age 21.
NDDOT distinguishes ordinary intrastate eligibility at 18 from interstate eligibility at 21. Its separate custom-harvesting provision is not general permission for younger interstate driving.

You obtained a North Dakota CLP five days ago and have completed the required training. Can you take the ordinary commercial road test now?
Correct answer: No; the CLP must have been held for at least 14 days.
Training completion and the permit holding period are separate requirements. NDDOT requires at least 14 days before the commercial road test.

Your North Dakota CLP reaches the end of its one-year period before you pass the skills test. Which assumption is wrong?
Correct answer: That the expired CLP automatically continues to authorize ordinary supervised practice.
The statute limits the permit to one year. It distinguishes a new permit after knowledge retesting from a limited letter for traveling to and completing the road test; neither is automatic indefinite practice authority.

A CLP holder wants to practice in a Class A combination. An experienced friend has only a Class D car license. Can that friend serve as the required commercial supervising driver?
Correct answer: No; the supervisor needs a valid CDL for the type of vehicle and must occupy the instructional seat beside the permit holder.
North Dakota requires an accompanying CDL holder qualified for the vehicle, seated beside the learner for instruction. An ordinary car license is not enough.

You have a North Dakota CLP with passenger and school-bus endorsements. May you use a practice drive to carry the regular school route's children?
Correct answer: No; the CLP is not authority to transport the regular passenger or school-bus load.
The permit's passenger endorsements allow the relevant learning process, not ordinary passenger service. The statute prohibits a CLP holder from transporting passengers requiring P or S.

A North Dakota CLP holder with the tank endorsement will practice with a tank vehicle. Its liquid has been drained, but hazardous residue remains. Is that permitted?
Correct answer: No; the tank must be empty and must not contain hazardous-material residue.
North Dakota's CLP rule requires both an empty tank and no hazardous-material residue. A drained tank can still fail that rule.

A North Dakota CLP holder is offered a hazardous-material load small enough not to require an H endorsement. Does that alone make carrying it under the CLP lawful?
Correct answer: No; North Dakota prohibits a CLP holder from transporting hazardous materials regardless of whether an H endorsement is required.
The state permit restriction is broader than the H-endorsement trigger. It expressly covers hazardous materials regardless of the need for that endorsement.

A new applicant seeks a first Class A CDL and has no applicable training exemption. Is self-study alone enough to satisfy entry-level driver training requirements?
Correct answer: No; the applicant must complete the applicable ELDT requirements through a registered training provider.
Current FMCSA guidance includes a first Class A or B CDL, a B-to-A upgrade, and first P, S, or H endorsements in ELDT scope. This question assumes no applicable exemption.
