Take a free, untimed Idaho DMV practice test in the real exam format: 40 questions, 34 correct to pass. Fresh random questions every attempt.
The Idaho knowledge test is a single 40-question exam covering road signs and the rules of the road together. You need 34 correct (85%) to pass.
Answer: Whoever arrives first
At a 4-way stop, the vehicle that arrives first generally has the right-of-way.
Right-of-Way
Answer: After coming to a full stop and yielding, unless a sign prohibits it
Right turn on red is allowed after a full stop and yielding, unless posted 'No Turn on Red.'
Signals
Answer: 1 to 4 points, depending on the violation
Idaho assigns 1 to 4 points per moving violation, though the handbook does not publish an exact violation-by-violation table.
ITD Point System
Answer: Within 18 inches
Idaho requires parking within 18 inches of the curb or edge of the road.
Parking Rules
Answer: Age 6 and under
Idaho requires children age 6 and under to be properly secured in an approved child safety seat.
Child Passenger Safety
Answer: No — but the bicyclist must still yield to vehicles already in or at the intersection before proceeding with caution
Idaho's 'Idaho stop' law lets bicyclists treat a stop sign like a yield sign — no full stop is required, but the bicyclist must yield to vehicles already in or at the intersection, then may proceed with caution.
Right-of-Way
Answer: Only from a one-way street onto another one-way street, after stopping and yielding
Left turn on red is legal only from a one-way street onto a one-way street, after stopping and yielding.
Signals
Answer: A warning letter
8-11 points within 12 months results in a warning letter — the first rung on Idaho's escalation ladder.

Questions and exam format researched against Idaho's official driver handbook and state sources. Last verified 20 August 2026.
Idaho Driver's Handbook (July 2026 edition), official PDF fetched directly from https://itd.idaho.gov/wp-content/uploads/2026/04/driver_manual.pdf — linked from the Idaho Transportation Department's own "Taking the Driver's Test" guide at https://itd.idaho.gov/guide/taking-the-drivers-test/, reached via the ITD DMV portal at https://itd.idaho.gov/dmv (dmv.idaho.gov 302-redirects there) — plus the ITD Graduated Driver Licensing (GDL) Fact Sheet, form ITD 3506 (Rev. 4/24), fetched directly from https://itd.idaho.gov/wp-content/uploads/2025/04/3506_gdlfactsheet.pdf. Researched and verified 2026-08-19; citation gap closed and both documents re-fetched and text-extracted 2026-08-20. CITATION CORRECTION 2026-08-20: the prior note labeled the handbook "ITD 01-9530906" — that form number appears NOWHERE in the extracted text of the live PDF (whose cover reads simply "DRIVER'S HANDBOOK / JULY 2026"), so it has been dropped rather than carried forward unverified; the July 2026 edition date and the ITD 3506 (Rev. 4/24) fact-sheet number ARE both confirmed verbatim in the fetched files. Mock exam format is fully confirmed by the current handbook, not estimated — its "Knowledge Test: Class D (Non-Commercial)" section states verbatim: "The knowledge test consists of 40 questions; you can miss up to six (6) questions before failing the test," i.e. 34/40 = 85%, drawn from one combined pool with no separate sign-recognition section (signCount: 0). Known gaps deliberately NOT invented, per the handbook's own silence on them: the exact dollar multiplier/fine amount for work-zone speeding penalties; a specific mph-over-limit threshold for reckless driving (Idaho's statute is conduct-based — 'willful disregard for safety' — with no fixed number given); a violation-by-violation points table (only the 1-4 point range and the suspension thresholds are published); the dollar fine amount for parking in a handicap space without a valid placard; an Idaho-specific weight/height bracket for child safety seats beyond the confirmed 'age 6 and under' rule; and any GDL-specific cell-phone restriction beyond the general statewide texting law (none was found for permit/provisional drivers specifically). Re-verify periodically, as ITD handbook content, fees, and thresholds change over time.
