Idaho Permit Practice Test 1
This free Idaho practice test has 30 multiple-choice questions covering road signs, right-of-way, speed limits, and safe driving — the same topics the DMV tests. The real DMV Class D Knowledge Test has 40 questions, and you need 34 correct (85%) to pass.
Question 1 of 30
1. How does the law treat a driver who leaves the scene of a crash they were involved in?
Show answer & explanation
Correct answer: B. Fleeing a crash you were part of, often called hit and run, is a serious crime everywhere, with penalties that grow if anyone was hurt. Staying is a legal duty. Whatever the damage, driving away doubles the trouble.
2. You see a red-and-white triangular sign reading YIELD as you approach a traffic circle. What should you do?
Show answer & explanation
Correct answer: B. A yield sign tells you to slow down, check for traffic with the right-of-way, and stop only when necessary to let it pass. It keeps merges smooth without forcing pointless stops. Think of yield as give way, not always stop.
3. On a two-lane Idaho highway posted at 60 mph, you want to pass a car going 45 mph. Driving a passenger car that is not towing anything, what does the law allow?
Show answer & explanation
Correct answer: B. On a two-lane Idaho road posted 55 mph or more, you may exceed the limit by up to 15 mph while passing a slower vehicle, but never in work zones. It shortens your time in the oncoming lane. Hook: fifteen extra to pass, then drop back.
4. You hit a stretch of heavy rain and patchy fog on the highway. How should you adjust your speed?
Show answer & explanation
Correct answer: B. In rain or fog, reduce speed until you could stop within the distance you can actually see, since wet pavement stretches stopping distance and fog hides hazards. Drive by sight distance: if you cannot see it, slow for it.
5. You are 15 and driving on an Idaho supervised instruction permit when you are convicted of running a stop sign. What happens to your permit?
Show answer & explanation
Correct answer: D. A traffic conviction during Idaho's supervised instruction period cancels the permit; you must reapply, pay again, and restart the full six violation-free months. The state wants proof of consistent safe habits. Hook: one ticket resets the whole clock.
6. You keep yawning and your eyes feel heavy on a long drive. What actually fixes drowsiness?
Show answer & explanation
Correct answer: A. Only sleep cures sleepiness, so pull off somewhere safe and rest when drowsiness hits. Loud music, open windows, and caffeine wear off within minutes, and a driver who nods off is as dangerous as a drunk one.
7. A classmate insists everyone must wait until 18 to start driving in Idaho. The real minimum age for a learner's permit is which of these?
Show answer & explanation
Correct answer: D. Your classmate is wrong: Idaho grants learner's permits at 14½. Starting earlier gives you months of supervised practice while risk is lowest. When rules feel fuzzy, confirm them in the official state driver handbook.
8. A friend in Idaho says, 'I feel fine, so I can drive.' Feelings aside, the law sets the illegal BAC for drivers 21 and older at which number?
Show answer & explanation
Correct answer: B. Feeling fine proves nothing; alcohol dulls the very judgment you use to check yourself. In Idaho, 0.08% is the per-se limit for adults, and measurable impairment often shows up well before a driver reaches it.
9. What can happen if you drive without a valid license or permit?
Show answer & explanation
Correct answer: C. Driving without a valid license or permit is illegal in every state; you can be cited, the vehicle may be towed or impounded, and the offense can push your real license further away. Patience now beats penalties later.
10. You pass a round yellow sign marked with a large black X and the letters R R. What is it telling you?
Show answer & explanation
Correct answer: A. The round yellow RXR sign is the advance warning for a railroad crossing, posted well before the tracks. It gives you time to slow, quiet distractions, and scan for trains. Round and yellow means railroad ahead, not at, the sign.
11. On any road sign, what does the color red always signal to drivers?
Show answer & explanation
Correct answer: D. Red is reserved for the strongest commands: stop, yield, do not enter, and wrong way. It marks actions that are forbidden or must halt. When red appears, something about your movement has to change right now.
12. A teen walks into a Division of Motor Vehicles (DMV) office in Idaho to apply for a first learner's permit. The office can accept the application once the teen is what age?
Show answer & explanation
Correct answer: B. The DMV accepts learner's permit applications at age 14½ in Idaho. Bring proof of identity, residency, and usually a parent's signature, then pass the knowledge and vision screenings. Age is simply the first box to check.
13. Children are playing near the curb on an unposted neighborhood street in Idaho. Unless a sign says otherwise, the fastest you may legally drive here is which speed?
Show answer & explanation
Correct answer: A. The default residential limit in Idaho is 35 mph unless otherwise posted. With children nearby, you should often go slower still, because stopping distance grows quickly with speed and kids can dart into the street without warning.
14. You are passing a slower vehicle on a two-lane road. May you go over the speed limit to finish the pass quickly?
Show answer & explanation
Correct answer: D. The speed limit applies at all times, including while passing another vehicle. If you cannot complete a pass legally and safely, do not start it. Passing is a choice; speeding is never the tool that makes it legal.
15. What is the right way to pass a bicyclist riding near the edge of your lane?
Show answer & explanation
Correct answer: B. Pass a bicyclist the patient way: ease off the gas, give plenty of side clearance, and wait until oncoming traffic allows a safe move. A wobble or pothole can push a rider sideways, so space is survival.
16. In Idaho, an under-21 driver can face a license suspension for alcohol at a much lower level than an adult DUI. That zero-tolerance level is which of these?
Show answer & explanation
Correct answer: D. Reaching 0.02% can cost a driver under 21 their license in Idaho, even when they show no obvious impairment. The state treats underage drinking and driving as a license issue first, aiming to stop the habit early.
17. You come to an intersection where the signal is flashing red. How should you treat it?
Show answer & explanation
Correct answer: D. A flashing red light works exactly like a stop sign: stop fully, yield to traffic and pedestrians, then proceed when the way is clear. Flashing red still means red, so a complete stop is always required.
18. You are driving on an Idaho state highway (not an interstate) with no speed limit signs posted. What is the maximum speed allowed?
Show answer & explanation
Correct answer: C. Unless a different limit is posted, Idaho state highways carry a 65 mph maximum, with 70 allowed only where signed; interstates are separate at 75 or 80. Lower defaults fit roads with driveways and cross traffic. Hook: state highways sit at sixty-five.
19. On its fastest highways, Idaho allows a top posted speed limit of which value?
Show answer & explanation
Correct answer: A. The highest speed limit in Idaho is 80 mph, and only certain highways are posted that high. Most roads carry lower limits, so drive by the signs in front of you, and slow down when conditions worsen.
20. Why is it illegal to park on a sidewalk or in a crosswalk?
Show answer & explanation
Correct answer: B. Sidewalks and crosswalks are reserved walking space; a parked car there pushes pedestrians, strollers, and wheelchairs out into traffic lanes. The law keeps walking paths continuous and safe. If people walk there, your car never belongs there.
21. A yellow diamond sign shows a small red stop sign symbol with an upward arrow. What should you do when you see it?
Show answer & explanation
Correct answer: C. A stop-ahead warning is used where the actual stop sign is hidden by a curve, hill, or trees. Start braking as soon as you see it, since the real stop will appear with little warning.
22. You merge onto an interstate in Idaho posted at the state's maximum speed limit. The fastest you may legally drive there is which speed?
Show answer & explanation
Correct answer: C. Idaho caps highway speed at 80 mph, its statewide maximum. Even on wide-open pavement, the posted number is the ceiling, and rain, fog, or traffic can make a much lower speed the only safe and legal choice.
23. While you practice driving on Idaho's supervised instruction permit, who must ride with you?
Show answer & explanation
Correct answer: B. During Idaho's supervised instruction period, your supervisor must be a licensed driver at least 21 years old sitting beside you, and no one else may occupy the front section. A coach within reach can catch mistakes instantly. Think: twenty-one, up front, alone.
24. Your brake pedal sinks to the floor and the car barely slows. What should you do?
Show answer & explanation
Correct answer: A. Pump the pedal quickly to build pressure back, shift to a lower gear, and ease on the parking brake while steering toward safety. Work through the list calmly: pump, downshift, parking brake, and pick your escape path.
25. How does the alcohol in a regular beer compare with a standard glass of wine or a single shot of liquor?
Show answer & explanation
Correct answer: B. A standard beer, glass of wine, and shot of liquor each deliver about the same alcohol, so switching drinks does not protect you. Your body counts drinks, not drink types. One is one, whatever the glass looks like.
26. Several vehicles reach a four-way stop at different times. Who has the right-of-way?
Show answer & explanation
Correct answer: B. At an all-way stop, the vehicle that arrives and stops first proceeds first, with others following in arrival order. This first-come, first-served system prevents confusion. Think of it as taking a number at a busy counter.
27. It is late at night and the unposted residential streets in your Idaho neighborhood are empty. The legal maximum for these streets remains which speed?
Show answer & explanation
Correct answer: C. Empty or busy, day or night, the default limit on unposted residential streets in Idaho stays 35 mph. Darkness actually cuts how far you can see and react, so conditions may call for less, never more, than the limit.
28. You are driving at night and can only make out the eight-sided outline of a sign ahead. Even before reading it, what does that shape tell you to do?
Show answer & explanation
Correct answer: C. The octagon is reserved for stop signs alone, so the shape itself orders a full stop. This lets you obey the sign even when snow, glare, or darkness hides the word. Eight sides always equals stop.
29. Who may legally park in a space reserved for people with disabilities?
Show answer & explanation
Correct answer: C. Reserved accessible spaces are only for vehicles showing a valid disability placard or plate, used when the person it was issued to is aboard. These wide, close-in spots are essential access, which is why enforcement is strict everywhere.
30. How should a lap and shoulder belt be worn so it protects you in a crash?
Show answer & explanation
Correct answer: D. Wear the lap belt low and snug over your hips and the shoulder belt across your chest, because those strong bones absorb crash forces safely. Belts on your belly or behind your back can cause serious internal injuries.
