Idaho Permit Practice Test 2
A second full-length Idaho practice test: 30 fresh multiple-choice questions with zero repeats from Test 1. The real DMV Class D Knowledge Test has 40 questions, and you need 34 correct (85%) to pass.
Question 1 of 30
1. In Idaho, what is the youngest age at which you can apply for a learner's permit?
Show answer & explanation
Correct answer: B. Idaho issues learner's permits starting at age 14½. The permit opens the first stage of graduated licensing, where you build skills with a supervising adult before earning fuller privileges. Know your state's number; it varies nationwide.
2. While you wait to turn, the green arrow changes to a steady yellow arrow. What is the signal telling you?
Show answer & explanation
Correct answer: D. A steady yellow arrow warns that the protected turning phase is about to end. Stop if you can do so safely; drivers already at the point of no return may finish the turn cautiously. Yellow arrow means wrap up, not speed up.
3. A freeway lane is marked with white diamond symbols, and a sign says the lane is for high-occupancy vehicles (HOV 2+). Who may drive in it during the posted hours?
Show answer & explanation
Correct answer: B. Diamond-marked HOV lanes are reserved for vehicles meeting the posted occupancy, like two or more people in an HOV 2+ lane. Rewarding shared rides moves more people in fewer cars. The diamond means special rules, so read the sign before entering.
4. You are involved in a crash with another vehicle. What does the law require you to do?
Show answer & explanation
Correct answer: D. After any crash you are part of, stop at once, get help for the injured, trade license, registration, and insurance details, and report the crash when required. Leaving without doing these turns an accident into a crime.
5. Your 20-year-old cousin is the designated driver tonight in Idaho. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In Idaho, drivers under 21 violate the zero-tolerance law once their BAC reaches 0.02%. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
6. Your younger sibling asks when they can get a learner's permit in Idaho. What age do you tell them?
Show answer & explanation
Correct answer: A. Tell them 14½; that is when Idaho allows a learner's permit application. Until then, driving on public roads is off the table. Graduated licensing phases in privileges so new drivers gain experience under lower-risk conditions.
7. How does alcohol change the skills you rely on to drive?
Show answer & explanation
Correct answer: B. Alcohol slows your reactions, throws off coordination, and blurs and narrows vision, so every core driving skill suffers at once. Impairment starts before you feel drunk. Think of alcohol as turning down every dial you drive with.
8. You are licensed in Idaho and under 16, so you may drive alone during daylight hours only. How does Idaho define daylight hours?
Show answer & explanation
Correct answer: A. For Idaho drivers under 16, daylight hours means a fixed window from 5:00 a.m. to 10:00 p.m. local time, not sunrise to sunset. A set clock rule is easier to follow and enforce. Memorize: five in the morning to ten at night.
9. Before turning left across oncoming traffic, why should you look twice for motorcycles?
Show answer & explanation
Correct answer: A. A motorcycle's narrow profile fools your eyes: it looks farther away and slower than it really is. Many rider deaths happen when cars turn left across their path. Look twice and judge twice before you commit.
10. On a multilane highway, white lines separate the lanes. What does the white color tell you about the traffic around you?
Show answer & explanation
Correct answer: B. White lines divide lanes of traffic that flow the same way, while yellow divides opposing flows. Reading line color at a glance tells you instantly where oncoming cars can be. White means with you, yellow means toward you.
11. You approach an intersection with no signs or signals, and another vehicle approaches from a cross street at about the same time. Who should yield?
Show answer & explanation
Correct answer: A. At an uncontrolled intersection, slow down and yield to any vehicle that reaches it at about the same time from your right. Without signs, this default rule sorts out conflicts. Same tiebreaker as a four-way stop: right goes first.
12. What is the safest way to carry young children in your vehicle?
Show answer & explanation
Correct answer: B. Children are safest buckled in the back seat, and a rear-facing seat must never sit in front of an active airbag, which can strike the seat with deadly force. Little riders belong behind you, away from the bag.
13. A wide white bar is painted across your lane just before an intersection with a stop sign. Where must you stop?
Show answer & explanation
Correct answer: D. A stop line marks the exact place to stop: bring your vehicle to a halt before the bar, not on or past it. It keeps you clear of crosswalks and cross traffic. The bar is the boundary.
14. A yellow diamond sign ahead displays a bold T symbol. What does this sign mean you will have to do soon?
Show answer & explanation
Correct answer: D. A T-symbol warning means your road dead-ends at a cross street, so you must slow, yield to crossing traffic, and turn left or right. The letter T shows exactly how the roads meet ahead.
15. A 30-year-old driver in Idaho takes a chemical test after a crash. Prosecutors can prove DUI from the test result alone once the BAC is at least which value?
Show answer & explanation
Correct answer: D. A test showing 0.08% or higher proves per-se DUI in Idaho without any other evidence of impairment. Lawmakers chose that threshold because crash risk climbs sharply near it, though alcohol degrades driving skills at lower levels too.
16. Setting cruise control on a rural Idaho interstate posted at the state maximum, you should set it no higher than which speed?
Show answer & explanation
Correct answer: B. The state maximum in Idaho is 80 mph, so cruise control should never be set above it where that limit is posted. Think of the posted limit as a ceiling for ideal conditions, never a required speed.
17. You are pulling out of a driveway onto a public street. What must you do?
Show answer & explanation
Correct answer: D. A driver entering a road from a driveway, alley, or private road must yield to sidewalk pedestrians and to all traffic already on the roadway. Public-road users cannot predict your exit, so the burden is on the driver emerging.
18. Where do you go in Idaho to take the Class D knowledge test and apply for your permit or license?
Show answer & explanation
Correct answer: D. Idaho licenses, permits, and knowledge tests are handled at county driver's license offices run through the county sheriff, not by ITD directly. Local offices keep services close to residents across the state. Hook: in Idaho, the sheriff runs the test.
19. You park facing downhill on a street with a curb. Where should your front wheels point?
Show answer & explanation
Correct answer: C. When parking downhill with a curb, turn your front wheels toward the curb; if the car rolls, the tire wedges against the curb instead of drifting into traffic. Think downhill, dive toward the curb, and set the brake.
20. You are driving at night with high beams on when a vehicle approaches from the other direction. What should you do?
Show answer & explanation
Correct answer: B. Dim to low beams for oncoming traffic so you never blind another driver. If glare hits you, look toward the right edge of your lane to stay on course. Courtesy with light keeps everyone able to see.
21. Your GPS routes you through a Idaho neighborhood of homes and parked cars with no posted speed limit. State law caps your speed there at what value?
Show answer & explanation
Correct answer: D. State law gives unposted residential areas in Idaho a default cap of 35 mph. Parked cars shrink your view of crossing pedestrians, which is exactly why the cap is low. Posted signs, where present, replace the default.
22. In places where marijuana can be bought legally, how do the laws treat driving while high?
Show answer & explanation
Correct answer: D. Legal to use never means legal to drive impaired. Marijuana slows reactions and distorts judgment of time and distance, so impaired-driving laws still apply everywhere. Treat being high exactly the way you would treat being drunk.
23. You are 16 and received your Idaho driver's license three months ago. Which passengers under age 17 may ride with you?
Show answer & explanation
Correct answer: C. For six months after licensure, Idaho drivers under 17 may carry only one passenger under 17 unless the riders are related by blood, adoption, or marriage. Teen passengers multiply distraction and crash risk. Hook: first six months, one young friend.
24. Under zero-tolerance laws, what happens to a driver under 21 caught with any measurable alcohol in their system?
Show answer & explanation
Correct answer: A. Every state enforces zero tolerance: drivers under 21 face penalties, typically license loss, for any measurable amount of alcohol. Because underage drinking is illegal, no level is acceptable. For young drivers, the only safe number is zero.
25. The posted limit is unchanged, but traffic, weather, and light have all gotten worse. What does the basic speed rule require?
Show answer & explanation
Correct answer: C. The basic speed rule says you may never drive faster than conditions safely allow, no matter what the sign posts. Rain, darkness, and crowds shrink your margin for error. Conditions set the real limit; the sign sets the ceiling.
26. You are approaching an intersection and the traffic light turns steady red. What must you do?
Show answer & explanation
Correct answer: C. A steady red light requires a full stop before the stop line or crosswalk, or before entering the intersection if there is no line. Stopping at the line protects people crossing. Remember: red means stop, every time.
27. During a practice drive in Idaho, your mom asks: 'No sign here, so how fast can you legally go on this residential street?' What is the correct answer?
Show answer & explanation
Correct answer: B. With no sign posted, the residential default in Idaho is 35 mph. A good habit for new drivers: entering any neighborhood, assume the default, scan for signs, and let posted limits override it whenever they appear.
28. An Idaho officer suspects you of DUI and asks you to take a BAC test. If this is your first refusal, what does Idaho law impose?
Show answer & explanation
Correct answer: B. Under Idaho's implied consent law, refusing an officer's request for a BAC test brings a $250 civil penalty and a one-year suspension with no driving privileges for a first refusal. Driving here means you already agreed. Hook: refuse the test, lose a year.
29. Two solid yellow lines run down the center of the road. What do they prohibit?
Show answer & explanation
Correct answer: D. Double solid yellow lines ban passing for traffic in both directions, because sight distance or traffic makes passing unsafe there. Crossing is generally allowed only to turn into a driveway or side road, never to overtake.
30. While planning a road trip across Idaho, you look up the fastest speed any of its highways allow. What is that statewide maximum?
Show answer & explanation
Correct answer: A. Idaho's top speed limit is 80 mph, found only on its fastest designated highways. Expect lower posted limits on most stretches, and remember signs always control: the maximum applies only where a sign actually posts it.
