The Class D knowledge test has 40 questions and you can miss up to 6 (34 correct, 85%). It is given at county driver's license offices in English, Spanish, Arabic, Chinese, Farsi, French, Korean, Russian, Serbo-Croatian, Swahili, Vietnamese and ASL; if you fail, you must wait 3 days to retest. Teens under 17 take it after finishing driver training and the supervised driving period, right before the skills test; applicants 17 and older must pass it to get a Class D instruction permit.

Tip: Start with module 1, “Idaho laws & permit rules”. These 12 questions cover rules that are specific to Idaho, the part of the test that general study guides usually miss.

Idaho learner permit and teen license rules

At 14 1/2 you can get a Driver Training Permit and take an approved course: 30 hours of classroom, 6 hours behind the wheel and 6 hours of in-car observation.
After the course, you must complete a supervised instruction period of at least 6 months with no violations; a ticket cancels the permit and restarts the 6 months.
Log at least 50 hours of supervised driving, including 10 hours at night, with a licensed driver 21 or older in the front seat.
The earliest you can get a Class D license is 15, after passing the knowledge and skills tests.
Under 16: you may drive alone only from 5:00 a.m. to 10:00 p.m. unless a licensed driver 21 or older sits in the front seat beside you.
Under 17: for the first 6 months after you are licensed, you may carry no more than one passenger under 17 unless they are related to you by blood, adoption or marriage.
Under 17 moving violations: the 1st conviction brings a warning letter, the 2nd a 30-day suspension and the 3rd a 60-day suspension.

How to get your Idaho learner's permit

At 14 1/2 or older, sign up for an approved public or private driver training program; you need a Driver Training Permit ($21.50) to attend.
Gather documents: proof of age and identity, Social Security number, Idaho residency, proof of school enrollment or completion, and a parent or guardian to sign as your liability signer.
Finish the course (30 hours classroom, 6 hours driving, 6 hours observation); you can then begin the supervised instruction period.
Drive at least 6 months with no violations and log 50 supervised hours (10 at night) with a licensed driver 21 or older.
Schedule your tests at a county driver's license office: vision check (20/40 standard), the 40-question knowledge test ($5) and the skills test.
After passing, pay the license fee at the county office and follow the under-16 and under-17 restrictions.

Frequently asked questions

Do I take the knowledge test before I start driving in Idaho?

Not if you are under 17. Teens get a Driver Training Permit, finish driver's ed and the 6-month supervised period, and then take the knowledge and skills tests together to get a license. If you are 17 or older, you must pass the knowledge test to get a Class D instruction permit.

What happens if I get a ticket during my supervised instruction period?

A traffic violation during the supervised period cancels your permit, and the 6-month, violation-free period starts over.

I'm 17. Do I still need driver's education?

No. Driver training is required only if you are under 17. At 17 or older you can get a Class D instruction permit, valid for 1 year, by passing the knowledge test, and practice with a licensed adult 18 or older.

How many points lead to a suspension in Idaho?

Twelve or more violation points in any 12-month period can get your license suspended. Drivers under 17 face extra penalties: a warning letter for the first moving violation, then 30-day and 60-day suspensions.

Are these the real DMV test questions?

No. The Idaho Transportation Department, Division of Motor Vehicles does not publish its exam. Our Idaho module is written from the official handbook and state law, and the core modules cover the rules of the road taught in every state handbook.

Is this practice test free?

Yes. Every lesson, practice round and exam simulation is free, with no sign-up.
