Mechanic testing process (Choose tab) 

Public Act 300 of 1974, also known as the Motor Vehicle Service and Repair Act (MVSRA), tasks the Secretary of State with oversight of mechanic testing used to indicate competency to perform motor vehicle repairs.

Mechanic tests are available at all Secretary of State offices throughout the state. Automotive schools also provide mechanic testing for their students and more information is available under the “Automotive schools mechanic testing” section on this page. You must pass a mechanic test for all of the categories in which you plan to perform repairs before you can apply for your mechanic certification. Each test is $6.

Mechanic Tests are only offered in English. Non-English speaking testers may utilize a translator. Testing accommodations are available by request for those with disabilities. Review the “Testing Accommodations” tab for more information.

All testers must utilize the e-Services online system to make an appointment to test. Michigan residents must also use the e-Services online system to pre-register for each test. Non-residents cannot pre-register for tests online and must do so in person at their scheduled appointment time. There is a $6 fee for each test and tests will not be issued within one hour of closing.

Tests are offered electronically utilizing a touch screen computer kiosk. Be sure to bring your state issued driver's license or state ID. It may be helpful to bring your receipt or confirmation number if you pre-registered online.

The test screen displays how many questions you have answered correctly as you are actively testing. You will be notified of your pass/fail status on the kiosk screen when you complete the test. The tests are “quick pass” so once you obtain the minimum passing score, the test will end without requiring you to finish all the questions.

A detailed test result letter will be mailed to you the next business day after completing your test.

There are currently 20 tests offered in the categories of Automotive/Light Truck (AUTO), Heavy Duty Truck (HDT), Motorcycle, and Miscellaneous:

Automotive schools mechanic testing (Choose tab)

The Michigan Department of State offers Michigan schools with accredited automotive programs the opportunity to administer the Michigan mechanic certification tests directly to their students. Approved schools may test as many students as they want, whenever they want, in the comfort and convenience of their own facility. There is no cost to install the system and each test is only $6.

The testing system is comprised of two web-based programs that work together; the State of Michigan CARS program, which you will access through the customer-facing, e-Services dashboard of the proctor computer, and the Know 2 Drive (K2D) program which runs in the background of the testing computers.

e-Services will only be accessed on the proctor computer by authorized staff, and will be used to register students, assign tests, start tests, review history and billing status, etc. Instructors are not allowed to proctor their own tests, but they may register the students and assign the exams in e-Services to stage them for a proctor to issue at a later time. Each staff member that accesses e-Services should have their own username and password.

The students can be registered for tests by the instructor or other school staff, or a link can be generated which will allow the students to self-register for their tests. There is a $6 charge for each test that is created that goes into the school account. Any account showing a balance will be invoiced monthly.

The proctor will launch each test from the e-Service dashboard on the main proctor computer, and it will appear on a designated tester computer for completion. The tester machines are configured and individually registered with the K2D program. Each tester station, once registered, will have an icon on the dashboard that can be used to launch the K2D program. Once launched, the test station will be visible to the proctor in e-Services and allow any available tests to be sent to the station for completion by the tester. K2D will remain open on the test station until it is terminated by using the key stroke combination of ALT-F4. It can be launched again from the desktop icon as needed.

Prior to installation of the testing system, a contract must be executed between the Michigan Department of State and the school or facility requesting the testing system. This contract will outline policies and procedures and well as the billing process. Administrator approval and school contact information must be obtained and will be used for creating the Mechanic Testing School Account in e-Services. Upon approval, the e-Services account will be created, and the desired number of test stations will be allocated to the school for configuration purposes. The configuration documents found in the "System Installation" tab will provide system requirements, provide configuration instructions for your IT staff, provide the installation credentials, and list the Help Desk phone number should assistance be necessary.

Frequently asked questions (FAQs)

  • To practice as a mechanic in Michigan, you must either have a valid mechanic trainee permit or have been certified in each repair category in which you wish to work.

    There are two ways to obtain the skills needed to become a certified mechanic:

    • Attend a school that offers automotive training. This usually includes hands-on learning along with classroom instruction.
    • Work at a repair shop with a certified, experienced mechanic who can teach proper repair methods and review that your work is done correctly.


  • Mechanic tests are offered on electronic, touchscreen testing stations at Secretary of State offices. You can start a mechanic test any time up to one hour before offices close. There is a $6 fee for each test attempt.  

    The tests contain multiple choice questions, ranging from 55 to 100 questions depending on the topic, and are intended to measure the minimum competencies necessary to work in that specialty. You are prohibited from using reference materials or electronic devices while taking your test.

    Your pass/fail status will display on the screen when you complete your test. A detailed test result letter will be mailed within seven days after testing.

    If you sign up for more than one test but don’t have time to complete all of them in the same visit, you may arrange to take the tests you haven't started at a later date, as long as you don’t exceed the 180-day limit.

  • You may retake any mechanic tests you didn't pass, but you must pay the test registration fee for each test you retake. You may only take one test per repair category per day.
