What the Idaho driver's license test covers

Idaho's driver's license test has two parts: a written knowledge test and a driving skills test. The written test covers traffic laws, road signs, and safe driving practices specific to Idaho. You take it at an Idaho Department of Transportation (ITD) office, and you must pass it before you can schedule the driving test.

The written test contains 40 multiple-choice questions. You need to answer at least 32 correctly to pass — that's 80 percent. The test draws from the Idaho Driver's Manual, which ITD publishes and makes available free online and in print at any ITD office. The questions focus on what you actually need to know to drive safely: speed limits, right-of-way rules, parking laws, and what different road signs mean.

The driving skills test happens after you pass the written test. An ITD examiner watches you operate a vehicle on public roads for about 20 to 30 minutes. They score you on steering control, mirror checking, lane changes, parking, and how you respond to traffic and pedestrians. You need to demonstrate that you can handle a vehicle safely in real conditions.

Key Takeaways

  • The written test has 40 questions and you must score at least 32 correct; it covers Idaho traffic laws and road signs from the Idaho Driver's Manual.
  • You can take the written test at any ITD office without an appointment, though wait times vary by location and time of day.
  • The driving test happens after you pass the written test and requires you to bring a vehicle, proof of insurance, and a valid ID.
  • You are allowed to retake either test if you fail, but you must wait at least one day before retesting for the written exam.

Preparing for the written test

Start with the Idaho Driver's Manual. ITD publishes it in English and Spanish, and you can read it online at itd.idaho.gov or pick up a printed copy at any ITD office. The manual is about 50 pages and covers everything the test asks about: traffic signs, right-of-way, speed limits, parking, and what to do in bad weather or emergencies.

Read through the manual once, then focus on the areas where you feel weakest. Many people find road signs and right-of-way rules the trickiest parts. ITD does not publish official practice tests, but several third-party websites offer Idaho-specific practice questions. These are not official, but they follow the same format and topics as the real test. Take a few practice tests to get comfortable with the question style and timing.

Plan to study for at least a few days before your test date. You do not need to memorize the entire manual — the test focuses on practical knowledge you will use while driving. If you have driven in another state, some rules will be familiar, but Idaho has specific laws you need to know, especially around winter driving and mountain roads.

Taking the written test at an ITD office

Walk into any ITD office during business hours. You do not need an appointment for the written test. Bring a valid photo ID — a passport, state ID, or military ID all work. You will fill out a short form with your name, address, and date of birth. There is a fee: as of 2024, the written test costs $10, though you should confirm the current fee when you arrive because it can change.

The test is given on a computer at the office. You sit at a terminal, read each question, and select your answer. You have as much time as you need — most people finish in 20 to 30 minutes. The computer tells you when ready whether you passed. If you pass, you get a receipt showing your score and the date. Keep this receipt; you will need it to schedule your driving test.

If you fail, you can retake the test the next day. There is no waiting period between attempts after the first failure, but ITD recommends studying more before your second try. You pay the fee again each time you test.

Scheduling and preparing for the driving test

After you pass the written test, you schedule the driving test by phone or online through ITD's website. You choose a date and time at an ITD office near you. Wait times vary: in busy areas like Boise, you might wait two to four weeks; in smaller towns, you could get in within days. Call ahead to see what dates are open.

For the driving test, bring three things: a valid photo ID, proof of insurance for the vehicle you will drive, and the vehicle itself. The vehicle must be in safe working condition — working brakes, steering, lights, and wipers. If the examiner notices a safety problem, they may cancel the test and you will have to reschedule.

You can bring your own vehicle or borrow one, as long as it is insured and registered. Some people use a driving school's car, which is allowed. The examiner will ask you to demonstrate basic skills: starting the engine, adjusting mirrors, turning, stopping, parking, and backing up. They will also have you drive on local streets and possibly a highway, depending on the office location.

What the examiner scores on the driving test

The examiner uses a scoring sheet that covers about 15 different driving tasks. You lose points for mistakes like failing to check mirrors, crossing the center line, braking too hard or too soft, not signaling, or hitting a curb while parking. Minor mistakes cost a few points; serious mistakes like running a red light or nearly hitting another car can result in an automatic fail.

You need to pass with a score of at least 70 percent. The examiner is looking for safe, controlled driving — not perfect driving. They understand that you are nervous and that you might make a small mistake. What they want to see is that you can handle the vehicle, follow traffic laws, and react safely to other drivers and pedestrians.

If you fail the driving test, you can retake it after waiting at least one day. You pay the fee again — currently $10 for the driving test as of 2024. Many people pass on their second or third attempt, especially if they practice more between tests.

Special rules for Idaho winter and mountain driving

Idaho's written test includes questions about winter driving because conditions change dramatically. You need to know when to use chains, how to drive on snow and ice, and what to do if you skid. The test also covers mountain driving — steep grades, switchbacks, and how to use lower gears on long downhill stretches.

If you are taking your driving test in winter, the examiner may ask you to demonstrate winter skills like gentle braking on slippery surfaces. If you are taking it in summer, they will not test winter skills directly, but you still need to know them for the written test. The Idaho Driver's Manual has a full section on both topics.

If you need to retake the test

Retaking either test is straightforward. For the written test, return to an ITD office, pay the fee, and take it again. You can do this as many times as you need. For the driving test, call ITD to reschedule. There is no limit on attempts, though some people find it helpful to take a few lessons with a professional driving instructor between attempts.

If you have been out of the country or have not driven in a long time, you may want to take a few practice drives before your test. This is especially true for the driving test — the examiner can tell the difference between someone who is nervous and someone who has not practiced.

Frequently Asked Questions

Can I take the written test online from home?

No. Idaho requires you to take the written test in person at an ITD office. This is to prevent cheating and to verify your identity. You cannot take it online or by mail.

What happens if I fail the driving test?

You can retake it after waiting at least one day. There is no limit on how many times you can test. You pay the fee each time. Many people pass on their second or third attempt after more practice.

Do I need a learner's permit before I take the driver's license test?

Yes. You must hold a valid Idaho learner's permit for at least 6 months before you can take the driving test. The learner's permit requires passing the written test first, so the written test serves double duty.

Can I use a rental car for the driving test?

Yes, as long as it is insured and registered. You can use your own car, a borrowed car, a rental car, or a driving school's vehicle. The vehicle must be in safe working condition with working brakes, lights, and wipers.

What if I fail the written test multiple times?

You can retake it as many times as you need. There is no limit. Study the Idaho Driver's Manual more thoroughly before your next attempt, or consider asking someone to quiz you on the material. Many people pass after their second or third try.
