Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
To obtain a CDL in New Mexico, you must pass three written permit tests — General Knowledge, Combination Vehicles, and Air Brakes — at the New Mexico Department of Motor Vehicles. Similar to a regular driver's license permit exam, these are timed, multiple-choice tests based on the official New Mexico CDL handbook.
All of our practice material is built from the official New Mexico CDL handbook and federal resources, and curated by professionals with over 10 years of experience in the commercial transportation industry. Studying with practice tests that mirror the real exam format is one of the most effective ways to pass on your first try.
On this page you'll find free practice tests for all three sections. For the full question bank and additional study features, download the CDL Help app.

Official New Mexico CDL Handbook
The official New Mexico CDL Driver's Manual covers every topic tested on the state's CDL knowledge exam — but it reads like a dense reference manual, not a structured study guide. A more effective way to prepare is with our General Knowledge practice tests. Our free New Mexico CDL permit practice test mirrors the format and content of the official exam and is fully up to date as of February 2026. Each practice test features 20 questions covering essential topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and New Mexico-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you actually learn from every question you answer.
- Complete CDL regulations and New Mexico-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements
Non-Domiciled CDL Information
Important information about non-domiciled commercial driver's licenses in New Mexico.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
New Mexico issues Non-Domiciled CLPs/CDLs in two scenarios: (1) applicants domiciled in another U.S. state placed out of compliance by FMCSA, and (2) non-U.S. citizens presenting qualifying immigration documents (Employment Authorization Card I-766, or unexpired foreign passport with approved I-94). Non-domiciled credentials are valid only for the period the individual is legally permitted to stay in the U.S. — if the legal presence document has an expiration date, the CDL expires on that date; if no expiration, the CDL is valid for one year. Applicants whose authorized stay is less than 30 days from application are ineligible. On October 6, 2025, the New Mexico MVD announced a pause on issuance and renewal of non-domiciled CDLs/CLPs for applicants using an Employment Authorization Card (I-766), while continuing to issue to applicants presenting a foreign passport with an approved I-94 record. At the time of the pause, NM had issued 204 CDLs and CLPs to non-domiciled individuals. This aligns with the broader FMCSA final rule published on February 13, 2026, limiting eligibility to H-2A, H-2B, and E-2 visa holders.[mvd][FMCSA Final Rule]
English Language Proficiency (ELP)
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in New Mexico.
New Mexico does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all New Mexico CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under this enforcement, roadside inspectors conduct a two-step assessment: first, a conversational interview in English — no interpreters or translation tools are permitted — to evaluate whether the driver can communicate sufficiently in English; second, the driver must demonstrate the ability to read and interpret standard U.S. traffic signs. Drivers who fail either step of the assessment are placed out of service under CVSA guidelines. New Mexico CDL applicants should be prepared to demonstrate English proficiency during any roadside inspection or compliance review.
