When turning left at an intersection with a green light (no arrow), you must: Go before oncoming traffic / Yield to oncoming traffic and pedestrians / Honk and turn / Wait for the light to turn red. Answer: Yield to oncoming traffic and pedestrians. A solid green light allows a left turn only when it is safe: yield to oncoming vehicles and to pedestrians in the crosswalk.
A solid yellow line on your side of the center line means: Passing is allowed / Do not pass / Lane for turning only / Bicycle lane. Answer: Do not pass. A solid yellow line on your side means passing is not allowed. A broken line on your side means you may pass when it is safe.
A round yellow sign with a black X and two R letters means: Road closed / Railroad crossing ahead / Rest area / Roundabout ahead. Answer: Railroad crossing ahead. This advance warning sign tells you a railroad crossing is ahead: slow down, look and listen, and be ready to stop.

How the Idaho DMV permit test works

The Idaho knowledge test (the learner's permit test) has 40 multiple-choice questions, and to pass you need 34 correct answers (you can miss up to 6), about 85%. Every question comes from the official DMV handbook, the Idaho Driver's Handbook.

English and most other language versions are offered in both written and audio form.

If you fail, you must wait three calendar days to retest and pay the knowledge test fee again.

Offered in English, Arabic, Chinese, Farsi, French, Korean, Russian, Serbo-Croatian, Spanish, Swahili, Vietnamese and American Sign Language.

Idaho learner's permit requirements

In Idaho you can apply for a learner's permit at 14½. Applicants under 18 usually need a parent or guardian's consent.

Applicants under 17 must pass an approved driver training program: 30 hours of classroom instruction, 6 hours behind the wheel and 6 hours of in-car observation with a licensed instructor.

Before the road test, teen drivers must hold the permit for at least 6 months. Supervised driving required: 50 hours, including 10 at night.

Proof of identity and date of birth (such as a birth certificate or passport).
Your Social Security number, if you have one.
Proof of Idaho residency.
A vision screening and the knowledge test.

The DMV publishes the exact document list: check it before your appointment, especially if you want a REAL ID-compliant card.

Idaho graduated driver licensing (GDL)

After the learner stage and the road test, teens can get a provisional (intermediate) license from age 15.

Drivers under 16 may drive only between 5 a.m. and 10 p.m. unless a licensed driver 21 or older sits beside them. For the first six months, drivers under 17 may carry no more than one passenger under 17 who is not a relative.

Restrictions end and you hold a full, unrestricted license at 17, provided your record stays clean.

Idaho rules worth knowing for the test

Signs and most rules are the same nationwide, but each state has its own laws — and the DMV test asks about them.

Permit drivers must have a licensed supervisor at least 21 in the seat beside them, and no other passengers may ride in the front seat.
A conviction or restriction violation cancels the permit, and the six-month supervised driving period starts over with the new permit.
ITD allows a translator for the knowledge test if your language is not offered, or after three failed attempts in an offered language.

What the Idaho knowledge test covers

Topics follow the chapters of the DMV handbook. These are the ones asked most often:

Road signs by shape and color (federal MUTCD standard): see the road signs guide.
Right-of-way at 4-way stops, left turns, crosswalks and for emergency vehicles: right-of-way rules.
Speed limits in mph and the 3-second following rule: speed guide.
Alcohol and drugs: the 0.08% BAC limit, zero tolerance under 21 and implied consent.
Traffic signals and pavement markings, parking, passing, and sharing the road with cyclists, motorcycles and trucks.

How to study for the Idaho permit test

Read the official DMV handbook once cover to cover, then take practice tests by topic to find your weak spots. Once you consistently score above 90%, take a full timed mock exam.

Drill the numbers — ages, distances, speed and BAC limits — they are the most-missed questions. More tips in how to pass the permit test.
