You must meet several requirements to obtain an instruction permit in Idaho. Importantly, you must pass a visual screening and a knowledge test and meet various documentation requirements, including verification of school compliance if you’re under 18. You must pay an instruction test fee to the DMV before they issue you an instruction permit.
The knowledge test has 40 questions based on the official driver’s manual (Idaho DMV Handbook (ID Driver's Manual) 2025). The passing score is 85%. You must pay the knowledge test fee to the DMV to take the test. If you fail it, you can retake it in three days, but you’ll have to pay the fee again.
We’ve always known there’s a significant chance of failing the knowledge test without adequate test preparation. (In 2020 – 2023, about 34.9% – more than one-third – of applicants failed the Idaho knowledge test on their first try.) Therefore, we’ve provided you with a variety of interactive test preparation tools to help you learn and memorize all the information you need to pass the knowledge test: an audiobook version of the official manual, a comprehensive series of practice tests based on the manual and arranged in increasing level of difficulty, and an automated assistant that can give you hints and explanations to help you answer the practice test questions and accelerate your learning process.

Now it’s time to see if you really are ready to take the official knowledge test!
This Exam Simulator test runs in Simulated Exam Mode, resembling official exam conditions. The test consists of 40 questions based on the official Idaho manual, just like those on the official DMV permit test. The passing score is 85%, just like the official permit test. Unlike our other practice tests, the Exam Simulator test ends prematurely if you fail it (i.e., if you miss more than 15% of the questions). Our automated assistant is unavailable for this test, so there are no hints or explanations to help you answer the test questions. On this test, you’re on your own, just like on the official knowledge test! The only significant difference from the official test is that you can retake the Exam Simulator test as often as you like until you feel confident and comfortable about taking the official knowledge test.
Plus, if you tend to experience test anxiety when taking official tests, then this Exam Simulator, by showing you just what to expect on the official test, may even help alleviate it.
Good luck!
