How do teens get an Idaho driver's license?

From 14½, you can get a Driver Training permit and take an approved driver training course: 30 hours of classroom instruction, 6 hours observing in the car, and 6 hours behind the wheel. Then you complete a 6-month supervised instruction period with at least 50 hours of driving, 10 of them at night, before taking the knowledge and skills tests (see ITD's young drivers page).

Do you need to pass the knowledge test before getting an Idaho permit?

If you're 17 or older and applying for a Class D instruction permit, yes. Teens under 17 on the supervised instruction permit take the knowledge and skills tests after completing the graduated licensing requirements.

What is not allowed during the Idaho knowledge test?

Electronic devices (including phones, smartwatches and earbuds), driver manuals or notes, talking with others, unauthorized interpreters, and leaving the testing area for anywhere other than the examiner.

Does ITD have an official practice test?

Yes. ITD's Practice Class D Drivers Test uses sample questions from ITD, and it's also available in Spanish. The practice tests on this page add more questions based on the handbook, with an explanation for every answer.

Is this the same as the Idaho DMV test?

In Idaho, driver licensing is handled by the Idaho Transportation Department (ITD) and county driver's license offices. These tests help you study the handbook material for its Class D knowledge test, but they are not the official test questions.
