Sample questions for Idaho

Three sample questions from our practice bank. Read the explanation after each.

  1. Question 1 · Knowledge test

    What passing score do you need on the Idaho knowledge test?

    • 70% (28/40)
    • 75% (30/40)
    • 80% (32/40)
    • 85% (34/40)
    See the explanation

    Correct answer: 85% (34/40)

    Idaho: get 34 of 40 right (85%) to pass — higher than most states.

  2. Question 2 · Mountain driving

    When descending a long, steep mountain grade in Idaho, how should you control your speed?

    • Ride the brakes the whole way down
    • Shift to a lower gear to use engine braking
    • Shift into neutral and coast
    • Turn off the engine to save fuel
    See the explanation

    Correct answer: Shift to a lower gear to use engine braking

    On long downhill grades, shift to a lower gear so your brakes don’t overheat.

  3. Question 3 · Lane use

    What is the purpose of a two-way left-turn lane in the center of a road?

    • For passing slower vehicles
    • For left turns by traffic from both directions
    • For emergency vehicles only
    • For high-speed through traffic
    See the explanation

    Correct answer: For left turns by traffic from both directions

    The center lane with turn arrows is only for making left turns — not for through travel.

Your first full mock exam is free.

Road signs you must know cold

Sign shapes: - Octagon = STOP - Triangle (point down) = YIELD - Diamond = WARNING - Pentagon = SCHOOL ZONE - Round = RAILROAD CROSSING - Rectangle (vertical) = REGULATORY - Rectangle (horizontal) = GUIDE Colors: - Red = stop / do not enter - Yellow = warning - Orange = construction - Green = direction - Blue = motorist services - Brown = recreation

Right-of-way rules that get tested every time

- Uncontrolled intersection: car on the right goes first. - Left turn: yield to oncoming traffic. - Pedestrians in crosswalk: always have the right of way. - Emergency vehicles with lights/siren: pull right and stop. - 4-way stop: first to arrive goes first; if tied, car on right wins. - School bus with red flashing lights: stop in both directions on undivided roads.

Idaho key rules to memorize

- Road signs and signals - Right-of-way rules - Idaho mountain and winter driving - Speed limits and safe following distance - Alcohol, drugs and safe driving

DUI and zero-tolerance — easy points

- Adult limit (21+): 0.08% BAC. - Commercial drivers: 0.04% BAC. - Under 21: zero tolerance (0.01–0.02% BAC). - Refusing breathalyzer = automatic license suspension ("implied consent"). - First DUI in Idaho: suspension, fines, mandatory classes, possible ignition interlock.

Stopping distances (rule of thumb)

Total stopping distance = perception + reaction + braking. At 55 mph in dry conditions: ~250–300 feet. Wet roads roughly double that. Follow the 3-second rule for following distance; 4–5 seconds in bad weather.

Frequently asked questions

Is this cheat sheet enough to pass the Idaho DMV test?

Strong head start, but on its own — no. Combine it with at least 100 practice questions and one full mock exam.

Is this cheat sheet up to date for 2026?

Yes — every fact comes from the current Idaho Driver's Handbook (2026). We update content within 30 days of any handbook revision.

Can I download a printable version?

Not yet — but you can print this page directly from your browser. PDF cheat sheets for paid users are coming.

Does the real Idaho test ask about exact stopping distances?

Rarely as exact numbers — more often as concepts (e.g., "what doubles your stopping distance?"). Understanding the rule matters more than memorizing feet.
