In New Mexico, the minimum age requirement for a Class A CDL license is 18 years old. However, drivers who are under 21 years old are restricted from operating a commercial motor vehicle for interstate purposes, meaning they cannot transport goods or passengers across state lines.

Drivers who are 21 years old or older may operate a commercial motor vehicle across state lines as long as they meet the other federal and state requirements for obtaining a CDL. It's important to note that some employers may have their own age requirements for certain types of commercial driving jobs.

To obtain an endorsement, you must pass a written knowledge test and, in some cases, a skills test. Some endorsements require additional background checks or other requirements. It's important to note that endorsements may have different age requirements and fees than the base CDL license.
The Class A CDL skills test is a two-part test that consists of a pre-trip inspection test and a driving skills test.

1. Pre-Trip Inspection Test: During this part of the test, you will be asked to demonstrate your knowledge of the commercial vehicle's components and safety features. You will be asked to visually inspect the vehicle and identify any potential safety hazards or mechanical issues.

2. Driving Skills Test: During this part of the test, you will be asked to demonstrate your driving skills in a commercial vehicle. You will be tested on your ability to safely handle the vehicle, including backing up, turning, and parking. You will also be tested on your ability to perform basic maneuvers, such as shifting gears and using turn signals.

The driving skills test is typically conducted on a closed course or in a controlled environment on public roads under the supervision of an examiner. The examiner will score your performance based on a set of criteria defined by the Federal Motor Carrier Safety Administration (FMCSA).

It's important to note that the Class A CDL skills test is a rigorous exam that requires significant preparation and practice. You should consider enrolling in a CDL training program to help you prepare for the exam and gain the necessary skills and knowledge to become a safe and competent commercial driver.

For example, if you only have experience driving tractor-trailers, you may be restricted from driving larger commercial vehicles like buses or tankers.
