1. What is the function of a regulatory sign?
Show answer
Answer A: To inform road users of traffic laws or regulations that apply at that location
Regulatory signs state requirements that carry the force of law where they are posted, so disregarding one is a violation rather than a lapse of judgment.
-
2. What does electronic stability control do that ordinary brakes cannot?
Show answer
Answer C: It brakes single wheels to bring the vehicle back on your intended path
The system compares where you have steered with where the vehicle is actually going, then brakes individual wheels to pull it back into line.
-
3. A regulatory sign reads TURN ON HEADLIGHTS NEXT 15 MILES. What does it require?
Show answer
Answer C: Low beam headlights on for that stretch, day or night
Such a section is signed where a road is hard to see along, and the requirement is to run headlights, not just daytime running lamps, through the whole stretch even in bright daylight.
-
4. On Idaho roads that are not interstates, not state highways and not in a residential, business or urban district, what does the law allow unless otherwise posted?
Show answer
Answer D: From 55 miles per hour up to 70 miles per hour
The Idaho handbook allows 55 miles per hour up to 70 in other locations unless a different limit is posted.
-
5. Your parking brake no longer holds the car on a slope. What should you do?
Show answer
Answer D: Have it repaired, and until then park only on level ground
A parking brake that will not hold is a defect to be fixed; avoiding grades in the meantime keeps the vehicle from rolling away.
-
6. Two vehicles reach a four-way stop at the same moment from adjacent roads. Who should go first?
Show answer
Answer A: The driver on the right
When two drivers stop at a four-way stop at the same time, the driver on the left yields to the driver on the right.
-
7. Where is a U-turn most clearly unsafe and generally prohibited?
Show answer
Answer D: On a curve or near a hill crest, where other drivers cannot see you
U-turns are barred where approaching drivers cannot see you in time, such as on a curve or near the top of a hill.
-
8. How many questions may an applicant miss on the Idaho Class D knowledge test and still pass?
Show answer
Answer A: Six
The Idaho Class D knowledge test contains 40 questions and an applicant may miss up to six of them before failing.
-
9. Idaho licenses drivers under 16 for daylight travel only. How does Idaho define daylight for this restriction?
Show answer
Answer D: From 5:00 a.m. to 10:00 p.m. local time
Idaho defines daylight for the under-16 restriction as 5:00 a.m. to 10:00 p.m. local time, unless a licensed driver at least 21 years old is in the front passenger seat.
-
10. Which of these is part of preparing a vehicle for winter driving?
Show answer
Answer A: Fitting good tires and using washer fluid that will not freeze
Winter readiness means tread, battery, wipers, antifreeze and washer fluid rated for the cold, plus a reasonable amount of fuel in the tank.
-
11. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
12. Your right-turn lane shows a green arrow while the through lanes face a red ball. What does that mean?
Show answer
Answer C: Only the right turn is allowed, and it is protected while the arrow lasts
A green arrow gives a protected movement in that direction only; the red ball still stops the through traffic in the other lanes.
-
13. Drivers from which country may keep their foreign license and skip the Idaho skills test?
Show answer
Answer D: Germany
Idaho exempts drivers from Germany from both surrendering the foreign license and taking the skills test, while drivers from Korea or Taiwan who keep their license must take the skills test.
-
14. A yellow diamond shows the two edges of the road pinching toward each other. What does it mean?
Show answer
Answer B: The pavement gets narrower but the lanes continue
The road narrows sign warns that the traveled way becomes tighter, leaving less room beside passing vehicles even though no lane is dropped.
-
15. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
16. In heavy stop-and-go traffic, why does using both lanes right up to a merge point help?
Show answer
Answer D: It stores the queue in two lanes, so the backup is shorter
Filling both lanes halves the length of the queue and keeps it away from the traffic upstream, which is why alternating at the merge point works better when traffic is slow.
-
17. What can follow from violating a posted speed limit in a designated Idaho work zone?
Show answer
Answer B: An enhanced, fixed penalty
Idaho attaches an enhanced, fixed penalty to violations of posted speed limits in designated work zones.
-
18. Why should you set the parking brake even when an automatic transmission is in Park?
Show answer
Answer B: Because it takes the strain off the transmission and holds the vehicle
The parking pawl is a small part carrying the whole vehicle; the parking brake shares that load and holds the vehicle if the pawl fails.
-
19. A flashing red lamp is mounted above a stop sign at a rural intersection. What does it add?
Show answer
Answer C: Emphasis, while the required stop stays the same
A stop beacon makes an easily missed stop sign more visible, but it neither adds to nor takes away from the obligation the sign already imposes.
-
20. How should a head restraint be adjusted?
Show answer
Answer D: So the top is at least as high as the back of your head and close behind it
A restraint set at head height and close behind limits how far the head snaps backward in a rear impact, which is what reduces neck injury.
-
21. About how much alcohol can the body eliminate per hour?
Show answer
Answer A: About one standard drink
The liver removes alcohol at a nearly fixed rate of roughly one standard drink per hour. Drinking faster than that raises the blood alcohol level, and nothing speeds the process.
-
22. Some states allow a left turn against a red light. Which movement is it?
Show answer
Answer A: A left turn from a one-way street onto another one-way street
The movement generally allowed on red is one-way to one-way, because the turn does not cross any lane of oncoming traffic; a few states also extend it to a two-way street turning onto a one-way street.
-
23. What is the safest way to handle an unrestrained pet or a child who needs attention while you are driving?
Show answer
Answer D: Secure pets before the trip and pull over safely before attending to a child
A loose animal or an urgent situation in the back seat can capture a driver's attention completely, so restrain pets beforehand and stop in a safe place when someone needs help.
-
24. An orange sign showing the symbol of a person holding a flag or a sign paddle means that
Show answer
Answer D: a person is controlling traffic ahead and the driver must obey that person
The flagger sign warns that a trained flagger is directing traffic further on, and the flagger's instructions govern movement through the work zone.
-
25. You pass into a work zone with a reduced speed limit but you see no workers. What speed applies?
Show answer
Answer D: The posted work zone limit, whether or not workers are present
A posted work zone speed limit is a regulatory limit in force at all times, and narrow lanes and uneven surfaces remain dangerous when nobody is working.
-
26. You are already inside a roundabout when an emergency vehicle approaches with lights and siren. What should you do?
Show answer
Answer B: Continue to your exit, leave the roundabout, then pull over and stop
Stopping inside a roundabout blocks the circulating roadway, so you should exit first and then pull over clear of the intersection.
-
27. A motorcycle ahead of you is weaving slightly as it crosses a stretch of grooved pavement. What should you do?
Show answer
Answer D: Give the rider extra room until the surface improves
Grooves, metal plates and loose material affect a motorcycle far more than a car, so back off and let the rider deal with the surface.
-
28. What can a loose or doubled up floor mat on the driver side cause?
Show answer
Answer A: It can slide forward and trap the accelerator pedal down
An unsecured mat, or a second mat laid over the first, can slip forward and hold the accelerator open. Use the mat clips and never stack mats.
-
29. What is the maximum number of points an ITD-approved Defensive Driving Course can remove from an Idaho driving record?
Show answer
Answer D: Three points
An ITD-approved Defensive Driving Course removes a maximum of three points and may be used only once every three years; a law enforcement Traffic Safety Education Course can remove up to four.
-
30. Is an SR-22 certificate accepted as the proof of insurance carried in the vehicle for an Idaho skills test?
Show answer
Answer B: No, an SR-22 is not valid proof of insurance for this purpose
Idaho requires valid paper or digital proof of insurance to be in the vehicle for the skills test and states that an SR-22 is not valid proof of insurance.
-
31. You are turning left into a street that is divided by a raised median. Which side should you enter?
Show answer
Answer C: The right-hand roadway, so that you travel on the proper side
A raised median separates two directions of travel, so the turn must be completed into the roadway carrying traffic your way.
-
32. The lights at a highway-rail grade crossing begin to flash red as you approach. What must you do?
Show answer
Answer B: Stop short of the tracks and wait until the lights stop and no train is near
Flashing red lights at a crossing require a stop clear of the tracks, and you may proceed only once the lights have stopped, any gates are fully raised and no train is approaching.
-
33. Why is it useful to watch the vehicle two or three places ahead of you?
Show answer
Answer C: You get an earlier warning of slowing traffic than brake lights give
Trouble travels back through a line of traffic, so seeing it start several vehicles ahead gives you a head start on braking.
-
34. What is the penalty for a second refusal of an evidentiary test within 10 years in Idaho?
Show answer
Answer D: A two-year absolute suspension
A second refusal within 10 years carries a two-year absolute suspension in Idaho, on top of any penalty the court imposes for a DUI conviction.
-
35. What can an Idaho driver be cited for after failing to give full attention to the safe operation of a vehicle?
Show answer
Answer A: Inattentive driving
Idaho requires drivers to give full attention to safe operation and provides a separate citation, inattentive driving, when they fail to do so.
-
36. Within what period must an Idaho Traffic Safety Education Course be completed for its points to be removed?
Show answer
Answer C: Within 45 days of the citation
The Traffic Safety Education Course must be offered by law enforcement at the time of citation and completed within 45 days of that citation for points to be removed.
-
37. A driver has to stop for a train at this sign. How far back from the nearest rail should the vehicle be held?
Show answer
Answer C: No closer than roughly fifteen feet
A train and its load overhang the rails, so stopping no closer than about fifteen feet keeps the vehicle outside the space the train actually sweeps.
-
38. A sign at the approach to a bridge reads WEIGHT LIMIT 10 TONS. What does the figure set?
Show answer
Answer B: The heaviest vehicle the bridge may legally carry
A weight limit sign is a regulation based on what the structure can bear, and it applies to the loaded weight of the whole vehicle.
-
39. How far ahead of expiration may an Idaho driver aged 21 or older renew a license in person?
Show answer
Answer A: Up to 25 months before the expiration date
Idaho allows in-person renewal up to 25 months before expiration for drivers 21 or older, unless the license carries a hazardous materials endorsement.
-
40. You are traveling a long distance on a highway with three lanes in your direction, at about the speed of the surrounding traffic. Which lane is generally the best choice?
Show answer
Answer C: The center lane, which keeps you clear of merging traffic and of overtaking traffic
On a three-lane roadway the center lane avoids both the ramp traffic on the right and the overtaking traffic on the left, so it usually has the steadiest flow.
