The MVD written test in New Mexico is offered in various languages, including English, Spanish, Tagalog, Italian, German, French, Vietnamese, and Chinese. Although language options are provided, it is advisable to have a basic understanding of English since road signs are always in English.

The New Mexico MVD written test comprises 25 questions. It is designed to evaluate your knowledge of road rules, safe driving practices, and traffic signs. You should study the manual carefully to ensure your success on the first attempt.

You must answer at least 18 questions correctly, and you can miss up to 7 questions to pass the MVD written test. The minimum score required to succeed in the exam is 70%. Take your time during the exam to make sure you understand the questions well.

When holding an instructional permit in New Mexico, new drivers must be accompanied by an approved driving instructor seated beside them or by an adult who is 21 years or older with a driver's license for at least 3 years. Upon obtaining a provisional license, drivers can drive alone, except between midnight and 5 a.m., unless:

In New Mexico, an instruction permit is valid for 4 years and can be renewed by the MVD. This ensures you have enough time to practice driving and fulfill the necessary requirements before the road test.

However, if you do not succeed on the second try, you have to wait one week before making another attempt.
