For a Wisconsin instruction permit you must pass two written tests: the highway signs test (15 questions, 12 correct to pass) and the knowledge test (50 questions, 40 correct to pass), plus a vision screening. Both tests are free at the DMV, and 15 to 17 year olds can take the knowledge test online at home for $10. This page covers formats, retakes, languages and what to study.

Taking the tests at a DMV service center

Walk in. The DMV does not take appointments for knowledge tests.
Arrive early: the knowledge test takes about 45 minutes and must be finished before the center closes.
Most centers use a touch screen with instant feedback. Audio assist is available on request, and paper tests can be given.
Every DMV customer service center offers the knowledge test except Milwaukee Downtown and Sauk City.

Can you take the Wisconsin permit test online?

Yes, the Class D knowledge test, if you are 17 or under. It is the same test as at the DMV, run by the DMV’s provider KnowToDrive.

Use a laptop or desktop with internet and a webcam. Tablets and smartphones are not allowed. The webcam takes random photos to confirm your identity.
A parent or guardian must monitor you the whole time.
Pay $10 per test, pass or fail.
You get two online attempts. Fail both and you take the third attempt at a DMV service center.
After passing, you get a certificate by email. Show it (printed or on your phone) at a DMV service center when you buy your permit.

The online test is available in English and Spanish.

Retakes

If you fail, you can retake no sooner than the next day.
You can take the same test five times in a one-year period. After five failed attempts you need special permission from DMV staff.

Test languages

The Class D knowledge and signs tests are offered in English, American Sign Language, Burmese, Chinese, Croatian, Hmong, Polish, Russian, Serbian, Somali and Spanish.

The vision screening

You need a visual acuity of at least 20/40 in one eye (with or without glasses) and a 70-degree field of vision from the center of each eye. If you do not pass, DMV staff will send you to a vision specialist with the Certificate of Vision Examination (MV3030V).

Common questions

Is the Wisconsin permit test hard?

You need 80% on both tests. The handbook is the only official study source, so read all of it, not just the signs section.

Do I need an appointment for the knowledge test?

No. Both written tests are walk-in.

Can I take the signs test online too?

The DMV’s online service is described as the Class D knowledge test. Check with the DMV whether the signs test must still be taken in person.

I’m 18. Can I test online?

No. The online test is only for ages 17 and under. Adults test free at a service center.

What happens after I pass?

You buy your instruction permit ($35 as of November 2026) at a DMV service center. Under 18 you also need your driver education enrollment and a sponsor. See the Wisconsin learner’s guide.

Is the online test the same as the DMV test?

Yes. The DMV says it is the same test offered at service centers.
