Idaho’s DMV written test is not something to wander into on a loose “I basically know how roads work” kind of confidence. The official Class D knowledge test pulls from the Idaho Driver’s Handbook, and it covers more than stop signs and who goes first at a four-way stop. You’ll see traffic laws, road signs, signals, pavement markings, safe driving practices, impaired driving rules, sharing-the-road situations, and the general responsibilities that come with being the person behind the wheel. The real Idaho Class D knowledge test has 40 questions. You need 34 correct answers to pass, which means an 85% score. That leaves room to miss 6, and not a generous 6 either, because a few careless mistakes can eat through that cushion pretty fast. If you fail, Idaho requires a 3-day wait before you can retest, and the testing fee has to be paid again. So, small detour here, but an important one: practice is cheaper than guessing. This free Idaho DMV practice test gives you 20 multiple-choice questions focused on the kind of material that actually deserves your attention, including Idaho road rules, safety habits, and details like proper seat belt use. It is untimed, which sounds like a minor feature until you are trying to figure out why two answer choices both seem almost right. Take the extra minute. Read the wording. Let the question be irritating for a second if it needs to be. It is also a useful fit for more than one type of driver. New drivers can use it while working through Idaho driver training and Graduated Driver Licensing requirements. Adults 17 and older preparing for a Class D instruction permit can use it to tighten up their handbook knowledge before testing. Out-of-state transfer applicants may need the knowledge test too, and anyone whose Idaho license has been expired for 25 months or more should expect the written test to come back into the picture. Use this Idaho DMV permit practice test with the Idaho Driver’s Handbook, not instead of it. That distinction matters, unfortunately. The practice test helps you catch weak spots, get used to the wording, and build enough test-day steadiness that the real DMV written test feels less like a surprise inspection and more like something you already had a decent look at beforehand.

Sample Idaho Permit Test Questions

Question 1

On a vertically arranged traffic signal, what is the correct order from top to bottom?

From top to bottom, the following is the proper order for traffic lights:
  1. A. Red, yellow, green
  2. B. Red, green, yellow
  3. C. Green, red, yellow
  4. D. Green, yellow, red

Correct answer: A. – Red, yellow, green

A standard vertical traffic signal places red at the top, yellow in the middle, and green at the bottom. This consistent arrangement helps drivers recognize the indications even when visibility is limited. On a horizontal signal, red is on the far left, yellow is in the middle, and green is on the far right.

Question 2

After stopping at a STOP sign, which vehicle must you yield to before entering?

  1. A. A vehicle already occupying the intersection
  2. B. Every vehicle on your right, even if it arrives later
  3. C. Every opposing vehicle, regardless of its distance
  4. D. Every vehicle on your left, even if it remains stopped

Correct answer: A. – A vehicle already occupying the intersection

After stopping, Idaho law requires a driver to yield to any vehicle already in the intersection. The driver must also yield to a vehicle approaching on another highway closely enough to create an immediate hazard while the driver crosses or enters. A vehicle’s direction alone does not determine priority under every circumstance.

Question 3

When parking uphill beside a curb, turn your front wheels:

When parking your vehicle facing uphill with a curb, you should point your front wheels:
  1. A. Toward the curb
  2. B. Sharply away from the curb
  3. C. In either direction
  4. D. Straight ahead

Correct answer: B. – Sharply away from the curb

When parked uphill beside a curb, turn the front wheels sharply away from and against the curb. If the vehicle begins rolling backward, the front tire should contact the curb rather than allowing the vehicle to roll into the roadway. When facing downhill, the wheels should instead be turned toward the curb.

Question 4

Drinking black coffee after consuming alcohol will:

  1. A. Quickly reduce the alcohol in your bloodstream
  2. B. Cancel alcohol-related impairment
  3. C. Not sober you up
  4. D. Increase the amount of alcohol in your bloodstream

Correct answer: C. – Not sober you up

The Idaho handbook explains that black coffee, exercise, eating, and similar measures will not sober a person after alcohol enters the bloodstream. These measures do not reverse alcohol’s effects on judgment, coordination, reaction time, or vision. Only the passage of time allows the body to return to normal.

Question 5

A solid yellow centerline separates:

  1. A. A center turn lane from adjacent traffic
  2. B. A bicycle lane from a motor-vehicle lane
  3. C. Lanes moving in the same direction
  4. D. Traffic moving in opposite directions

Correct answer: D. – Traffic moving in opposite directions

Yellow centerlines separate traffic traveling in opposite directions on a two-way road. The line pattern determines whether crossing is allowed for passing; a solid line restricts passing from the side next to that line. White lane lines, rather than yellow centerlines, normally separate lanes moving in the same direction.

Question 6

Driving substantially slower than normal traffic without a safety-related reason can:

  1. A. Disrupt traffic flow and violate the minimum-speed rule
  2. B. Always make travel safer
  3. C. Have no effect on surrounding traffic
  4. D. Be required as a defensive-driving technique

Correct answer: A. – Disrupt traffic flow and violate the minimum-speed rule

Idaho prohibits driving so slowly that normal and reasonable traffic movement is impeded, except when a reduced speed is necessary for safe operation or compliance with law. The handbook also warns that driving too slowly for existing conditions can disrupt safe traffic flow. Drivers should select a reasonable and prudent speed for the actual conditions.
