Question 1 of 30
1. You are making a study calendar for the Idaho knowledge test. You can hold a learner's permit beginning at which age?
Show answer & explanation
Correct answer: B. Put 14½ on the calendar for Idaho. That is the first legal day for a learner's permit, after you pass the knowledge and vision screens the DMV requires.
2. Why do most GDL programs limit teen passengers in the first months of licensure?
Show answer & explanation
Correct answer: A. Crash data show that extra teen passengers raise risk more than almost any other GDL factor. The limit is a safety rule, not a punishment. Fewer friends in the car means more attention on the road.
3. You are driving in a lane with a large white arrow painted on the pavement curving to the right. What does this marking require?
Show answer & explanation
Correct answer: B. A curved lane-use arrow makes that lane turn-only: follow the arrow or change lanes before the intersection. The arrows sort traffic early so drivers do not swerve at the last second. The pavement is telling you your path.
4. A vehicle in front of you is stalled on railroad tracks and will not restart. The crossing lights start to flash. What should you do?
Show answer & explanation
Correct answer: B. People beat cars. Evacuate at once and run toward the train at an angle so debris is less likely to hit you if the car is struck. Do not stand on the tracks. Restart attempts end when the lights start.
5. Under Idaho's zero-tolerance law, what BAC level counts as a violation for a driver under 21?
Show answer & explanation
Correct answer: B. Idaho's zero-tolerance law sets the under-21 threshold at 0.02%, far stricter than the adult standard. Underage drinking is illegal to begin with, so the safest and simplest rule is zero alcohol before driving.
6. In Idaho, supervised behind-the-wheel practice with a permit can begin once a teen reaches which age?
Show answer & explanation
Correct answer: C. Supervised practice starts at 14½ in Idaho, once the teen holds a learner's permit. Every practice hour with a licensed adult builds judgment that classroom study alone cannot teach, which is why the permit stage exists.
7. You have signaled and checked your mirrors before a lane change. What is the one step left before you move over?
Show answer & explanation
Correct answer: C. Mirrors leave blind spots big enough to hide a whole car, so turn your head for a quick over-the-shoulder check before moving over. Signal, mirrors, head check: the lane change is not done until your neck moves.
8. You fail the Class D knowledge test at your Idaho county driver's license office. What are the rules for retaking it?
Show answer & explanation
Correct answer: A. Fail the Idaho knowledge test and you must wait three days before trying again, paying the $5.00 fee for every attempt. The gap pushes you to actually restudy the handbook. Remember: three days and five dollars per try.
9. What is double parking, and why is it against the rules?
Show answer & explanation
Correct answer: D. Double parking means standing or parking in the roadway alongside a vehicle already parked at the curb. It blocks a travel lane, hides pedestrians, and pins in the parked car, so the practice is prohibited on public streets.
10. 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.
11. What does a posted speed limit actually tell you?
Show answer & explanation
Correct answer: A. A posted limit is the top legal speed when conditions are ideal: dry pavement, good visibility, light traffic. In worse conditions, a safe speed is lower. Treat the number as a ceiling to stay under, not a target to hit.
12. A traffic light is circular yellow after you have already entered the intersection on green. What should you do?
Show answer & explanation
Correct answer: B. Once you are in the intersection on green, a yellow that follows means finish the crossing smoothly. Stopping mid-box blocks others and can get you hit from behind. Yellow before the line means stop if you can; yellow after the line means clear out.
13. You reach a stop sign at an intersection that has a painted stop line. Where must you bring your vehicle to a complete stop?
Show answer & explanation
Correct answer: A. At a stop sign you must stop completely before the stop line; with no line, stop before the crosswalk or the intersection edge. Stopping short protects people in the crosswalk. If you need a better view, creep forward only after the full stop.
14. Along a curb you see a white sign with a large letter P inside a red circle and slash. What does it tell you?
Show answer & explanation
Correct answer: C. A P covered by a red circle and slash is the international no-parking symbol, banning parking where the sign applies. It keeps curbs clear for visibility, hydrants, and traffic flow. Any symbol wearing the red slash is something you cannot do.
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. 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.
17. When do reduced school zone speed limits typically apply?
Show answer & explanation
Correct answer: D. School zone limits usually apply during posted times, when the zone's beacons flash, or whenever children are present. Kids are small, quick, and unpredictable near schools. When you see the zone active, drop your speed and cover the brake.
18. 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.
19. 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 does not mean 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.
20. A power outage has left the traffic signals at an intersection completely dark. What should you do?
Show answer & explanation
Correct answer: A. When a signal is completely dark, treat the intersection as an all-way stop: stop fully, yield to vehicles that arrived first, and proceed in turn. This shared rule keeps order when the usual electronic referee is offline.
21. 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, not more, than the limit.
22. A tire blows out at highway speed. What should you do first?
Show answer & explanation
Correct answer: B. A blowout pulls the car; your job is to keep it pointed straight while speed drops. Hard braking can spin you. Once you are slow and under control, signal and move off the pavement. Hold, ease, then brake.
23. You have an Idaho green light, but vehicles are stacked in the intersection. What should you do?
Show answer & explanation
Correct answer: A. Idaho tells you that if you are already in the intersection you should continue moving and clear it safely. Do not enter a packed green and then stop in the middle. Wait for space on the far side so you do not block cross traffic.
24. How much of a traffic lane is a motorcycle entitled to use?
Show answer & explanation
Correct answer: D. A motorcycle is entitled to a complete traffic lane, and you may not squeeze past one inside that lane. Riders need the full width to dodge hazards. Treat a motorcycle's lane like a car's lane: whole and off-limits.
25. You are on a through street. A driver on a driveway to your right is waiting to enter. Who must yield?
Show answer & explanation
Correct answer: B. Drivers leaving a driveway, alley, or parking lot yield to all traffic on the street, including bikes and people walking. The street already has the flow. Think: entering traffic waits; through traffic keeps moving unless a sign says otherwise.
26. Headlights are required from sunset to sunrise. When else should you turn them on?
Show answer & explanation
Correct answer: B. Wipers on, lights on is the rule many states write down and testers repeat. Lights help others see you as much as they help you see. If the sky is gray or the glass is wet, flip them on.
27. You are delivering food to a house on an unposted residential street in Idaho. Unless a sign changes it, what speed limit applies?
Show answer & explanation
Correct answer: A. Unposted residential streets in Idaho carry a default limit of 35 mph. The rule exists so drivers can stop for the unexpected, like a car backing out of a driveway. When a sign is posted, obey the sign instead.
28. Which Idaho no-parking distances does the driver’s manual list?
Show answer & explanation
Correct answer: A. Idaho forbids parking within 15 feet of a fire hydrant, 20 feet of a crosswalk, 30 feet of a stop sign, yield sign, or traffic signal, 20 feet of a fire-station driveway, and 50 feet of railroad tracks. Learn 15 / 20 / 30 / 50 as a set.
29. Small green signs with numbers appear every mile along the edge of the highway. What are these mile markers mainly used for?
Show answer & explanation
Correct answer: C. Mile markers count the distance across a route, letting you track your progress, judge how far your exit is, and give an exact location when you call for help. Note the nearest marker whenever trouble starts.
30. 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.
