  1. Question 1 · General Rules

    It is important to slow down:

    • AOnly when you see a posted speed-reduction sign
    • BIn school zones and work zones only
    • CWhenever weather, road conditions, or hazards require it✓ Correct

    Why: Idaho's 'basic rule' requires driving at a speed that is reasonable and prudent given the road surface, visibility, hazards, and other conditions — not just where signs are posted.

  2. Question 2 · Speed Limits

    Which statement about speed is true?

    • AYou may exceed posted speed limits slightly in good weather
    • BPosted limits may always be driven regardless of conditions
    • CPosted limits are maximums for ideal conditions; conditions may require slower speeds✓ Correct

    Why: Idaho's 'basic rule' requires driving at a speed that is reasonable and prudent at all times, even if that means driving below the posted maximum in poor conditions.

  3. Question 3 · Traffic Signs & Signals

    When approaching a steady green traffic light, drivers should:

    • AStop briefly to check for cross traffic
    • BProceed if the intersection is clear, yielding to pedestrians✓ Correct
    • CAccelerate to clear the intersection quickly

    Why: A green circular light means 'go,' but you must yield to oncoming traffic and to pedestrians in crosswalks before proceeding or turning.

  4. Question 4 · Turns & Intersections

    When making a left turn:

    • ASignal, yield to oncoming traffic, and turn into the nearest lane going your direction✓ Correct
    • BProceed without signaling if no oncoming traffic is visible
    • CTurn into any available lane on the cross street

    Why: For left turns, signal, approach in the leftmost lane, yield to pedestrians and oncoming vehicles, and turn into the nearest lane where traffic moves in your direction.

  5. Question 5 · Right of Way

    At an uncontrolled intersection, two vehicles arrive at the same time. Who has the right of way?

    • AThe vehicle on the right has the right of way✓ Correct
    • BThe vehicle on the left has the right of way
    • CThe larger vehicle has the right of way

    Why: At an unmarked or uncontrolled intersection, when two vehicles arrive at the same time the vehicle on the left must yield to the vehicle on the right.

  6. Question 6 · Lane Changes & Passing

    Passing is prohibited:

    • AAt any railroad crossing or within 100 feet of one✓ Correct
    • BOnly when pavement is wet or visibility is reduced
    • COnly when solid double yellow lines are present

    Why: Passing is prohibited within 100 feet of a railroad crossing, within 100 feet of an intersection, and anywhere your vision of oncoming traffic is obstructed.

  7. Question 7 · Parking Rules

    When parking parallel to a curb or the edge of the roadway, you must park:

    • AFacing oncoming traffic on your side of the road
    • BNo more than 24 inches from the curb in any direction
    • CNo more than 18 inches from the curb, facing the same direction as traffic on your side✓ Correct

    Why: When parking on a public road you must park parallel to and within 18 inches of the curb, facing the same direction as traffic on your side of the street.

  8. Question 8 · Weather & Visibility

    To drive safely at night, you should:

    • AIncrease your following distance and keep your headlights on✓ Correct
    • BDrive at the same speed as during the day
    • CUse high beams when meeting oncoming vehicles

    Why: At night, increase your following distance, keep your headlights on from sunset to sunrise, and look away from the headlights of oncoming vehicles to avoid glare.

  9. Question 9 · Driver Readiness

    Driving while being distracted by any activity:

    • APoses a risk only at highway speeds
    • BIs safe if the distraction lasts fewer than 3 seconds
    • CSignificantly increases your risk of being in a crash✓ Correct

    Why: If something distracts you for even a few seconds, you may fail to see a hazard in time to avoid a crash. You must give full attention to driving at all times.

  10. Question 10 · DUI Laws

    Alcohol affects your driving by:

    • AImproving your confidence while sharpening reaction time
    • BSlowing reaction time and impairing judgment and coordination✓ Correct
    • COnly impairing drivers who exceed the legal BAC limit

    Why: Even after a few drinks, alcohol impairs reaction time, coordination, balance, and vision, making it harder to react to dangers ahead on the road.

    Source: Idaho Driver Handbook, page 129 · How Drinking Affects You

  11. Question 11 · Accidents & Emergencies

    When an emergency vehicle approaches sounding a siren or flashing red or blue lights, you must:

    • APull to the nearest right curb or edge of the road and stop✓ Correct
    • BSpeed up to clear the path quickly
    • CStop in your current lane and let it pass

    Why: When approached by an emergency vehicle sounding a siren or flashing lights, immediately pull to the right edge of the road and remain stopped until it has passed.

  12. Question 12 · Highway Driving

    If you are driving on the interstate and miss your exit, you should:

    • ABack up on the shoulder to reach your exit
    • BMake a U-turn at the next median crossover
    • CContinue to the next exit and find a safe route back✓ Correct

    Why: If you miss an exit, never back up. Freeway median crossovers are for emergency vehicles only, so continue to the next exit and find a safe route back.

Idaho-specific rules to know

A few traffic rules that are particular to Idaho and frequently show up on the test.

How to get your Idaho driver's license

The knowledge test is one step in Idaho's licensing process. Here's how the path typically works for a new driver.

  1. Check the age and eligibility requirements

    Eligibility in Idaho: 14½ for a supervised instruction permit with driver training; 15 for a Class D driver's license. Have your proof of identity, residency, and any required parental consent ready.

  2. Study the official handbook

    Read the Official Idaho Driver's Handbook (itd.idaho.gov) and practice with DMV Ace until you're consistently scoring above 85%.

  3. Pass the knowledge test

    The Idaho written test has 40 questions, and you need 34 correct (85%) to pass. Permit/licensing fee: $21.50 for a supervised instruction permit (includes a $6.50 skills-test receipt fee); a driver-training course adds about $15.

  4. Build supervised driving experience

    Hold your permit for the period Idaho requires and log supervised driving hours with a licensed adult before you schedule the road test.

  5. Pass the road test and get licensed

    After you pass the behind-the-wheel road test, Idaho issues your driver's license — often an intermediate/provisional license first for younger drivers.

Steps are a general guide — always confirm the current process with your local Idaho DMV office.

Idaho DMV permit test — common questions

How many questions are on the Idaho DMV knowledge test?

The Idaho knowledge test has 40 multiple-choice questions. You must answer at least 34 correctly (85%) to pass, and the Idaho Transportation Department does not impose a time limit on the written test.

What's the passing score for the Idaho permit test?

85% (34 of 40) — meaning you can miss no more than 6 of the 40 questions. The threshold is the same for first-time testers and retakes.

What's the minimum age to get a permit in Idaho?

You can apply for a supervised instruction permit at 14½ if you are enrolled in or have completed an approved driver-training course. A Class D driver's license is available at 15 after completing the GDL requirements.

Can I take the Idaho knowledge test online?

No. Idaho requires the knowledge test to be taken in person at a County Sheriff's driver's license office, where you also complete your application and vision screening. Check itd.idaho.gov for your local office.

How many times can I retake the Idaho test if I fail?

There is no overall limit on attempts, but if you fail you must wait at least three days before retaking the knowledge test. A test 'passed' during that three-day window is invalid, and test fees must be paid again for each retake.

How much does an Idaho permit cost?

The supervised instruction permit is $21.50, which includes a $6.50 fee collected in advance for your skills-test receipt. An approved driver-training course adds about $15. Fees are non-refundable.

What is Idaho's daylight-only driving rule for teens?

GDL licensees under 16 may only drive from a half hour before sunrise to a half hour after sunset, unless a licensed driver who is at least 21 years old is seated beside them in the vehicle.

How many supervised driving hours does Idaho require?

An Idaho permit holder must complete 50 hours of supervised driving — including at least 10 hours at night — with a licensed driver 21 or older in the front passenger seat before applying for a Class D license.
