1. What is threshold braking?
Show answer
Answer C: Braking hard but staying just short of locking the wheels
A rolling tire grips better than a sliding one, so the shortest stop comes from pressure held just below the point where the wheels lock.
-
2. Someone stops drinking heavily at two in the morning and drives to work at eight. What is true?
Show answer
Answer A: They may still be impaired and over the limit
The body removes alcohol at a slow, fixed rate, so a heavy night can leave a driver impaired well into the next morning no matter how they feel.
-
3. If you must abandon a vehicle stuck on the tracks with a train coming, why do you move toward the train and away at an angle?
Show answer
Answer D: Because debris from the impact is thrown forward, away from the train
A train pushes wreckage down the track ahead of it, so walking toward the train and off to the side keeps you out of the debris path.
-
4. A stop line is painted across the pavement at this sign. Where must the vehicle come to rest?
Show answer
Answer A: Behind the stop line, with no part of the vehicle across it
The vehicle must halt behind the stop line; where no line is painted the driver stops before the crosswalk, and where there is neither, before entering the intersection.
-
5. A yellow diamond shows two lanes narrowing into one. What does it require of a driver?
Show answer
Answer D: Adjusting speed and merging before the lane disappears
The lane ends sign gives notice that one lane will be dropped, so drivers should adjust speed and blend into the continuing lane in good time.
-
6. You brake hard in a vehicle with antilock brakes and feel the pedal pulsing under your foot. What should you do?
Show answer
Answer A: Keep firm, steady pressure on the pedal and steer where you need to go
The pulsing is the system releasing and reapplying the brakes so the wheels keep rolling, which is what lets you steer while braking. Pumping the pedal defeats it.
-
7. Visibility drops suddenly and you decide to leave the highway. What is the safest way to do it?
Show answer
Answer A: Take the next exit or a wide pull off, well clear of the traffic lanes
Get right off the traveled way, and off the shoulder too if you can, because vehicles in poor visibility often drift onto the shoulder.
-
8. You are turning onto a street that has two lanes going your way. Which lane should you enter?
Show answer
Answer B: The lane closest to you, changing lanes later if you need to
Turn into the nearest lane going your direction and make any lane change afterwards, when you have signaled and checked that it is clear.
-
9. What should you expect while driving through a parking lot?
Show answer
Answer D: Pedestrians and vehicles moving from any direction, so drive slowly
Parking lots mix walking people, reversing vehicles and poor sight lines, so low speed and constant scanning are the only reliable protection.
-
10. What minimum visual acuity must an applicant meet at an Idaho vision screening?
Show answer
Answer D: 20/40 in at least one eye, with or without corrective lenses
Idaho screens vision at every license transaction and requires at least 20/40 in one eye, with or without corrective lenses; wearing lenses during the screening adds a lens restriction.
-
11. After a court judgment against an uninsured driver in Idaho, how long may the department suspend that driver's privileges?
Show answer
Answer A: Until the judgment is paid, or for up to six years
Idaho lets the department suspend an uninsured driver's privileges until the injured party has been paid, or for up to six years.
-
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. You are backing out of a space in a parking lot. Who has the right of way?
Show answer
Answer D: Traffic already moving in the lane, and pedestrians walking behind you
A driver backing out must yield to vehicles and pedestrians already using the lane, because backing is the movement with the poorest view.
-
14. After an hour on a hot highway your tire pressure reads higher than it did in the morning. What should you do?
Show answer
Answer D: Nothing, because pressure rises when tires heat up
Air expands as the tire warms, so a hot reading is normally above the cold setting. Bleeding air off would leave the tire underinflated once it cooled.
-
15. In a work zone a flagger is directing traffic in a way that conflicts with the posted signs. Whom do you follow?
Show answer
Answer B: The flagger's directions
A flagger controls traffic through a work area that changes from day to day, and those instructions take precedence over the fixed signs and markings in that zone.
-
16. You hear a bang and one of the front tires deflates while you are on the highway. What happens to the vehicle?
Show answer
Answer D: It pulls strongly toward the side that failed
The collapsed tire drags heavily on that corner, so the vehicle veers toward it. Hold the wheel firmly, keep your line and let the speed fall before leaving the road.
-
17. There is a driveway and a side street between you and the corner where you will turn right. When should you signal?
Show answer
Answer C: After passing the openings, so nobody pulls out in front of you
A signal switched on before an opening tells drivers waiting there that you are turning in, and they may pull out into your path.
-
18. A highway lane is marked with a large white diamond and signed as a high-occupancy vehicle lane. Who may use it?
Show answer
Answer B: Only vehicles carrying at least the number of occupants shown on the sign, during the posted hours
The diamond marking identifies a preferential lane whose occupancy requirement and hours of operation are stated on the accompanying signs.
-
19. You are about to change lanes to the left when you notice a vehicle already overtaking you in that lane. What should you do?
Show answer
Answer A: Hold your lane and your speed, and change only after that vehicle has gone by
A signal asks for space but does not create it, and the overtaking driver has nowhere to go if you move across.
-
20. Your brake pedal sinks to the floor and the vehicle does not slow down. What is a reasonable sequence of actions?
Show answer
Answer C: Pump the pedal, shift to a lower gear and apply the parking brake gradually while steering to a safe spot
Pumping can rebuild pressure in a partly failed system, a lower gear adds engine braking, and easing on the parking brake slows the vehicle without locking the wheels.
-
21. When should you move into the lane you need for a turn?
Show answer
Answer D: Well before the intersection, as soon as you know your route
Getting into the correct lane early lets other drivers read your intentions and keeps you from making a sudden lane change at the corner.
-
22. The electric windows will not work as your vehicle sinks in water. What is the best option?
Show answer
Answer C: Break a side window with a hard, pointed object and climb out through it
Side windows are tempered glass and can be broken, while the laminated windshield cannot, and water pressure holds the doors shut.
-
23. Who may ride along during an Idaho Class D skills test?
Show answer
Answer A: A parent or guardian, translator, missionary companion or law enforcement officer
Passengers are barred except for a parent or legal guardian, a translator, a missionary companion or a law enforcement officer, all of whom must be 18 or older and sign the liability waiver.
-
24. You park a manual transmission car facing uphill at a curb. What is the correct combination?
Show answer
Answer A: First gear, wheels turned away from the curb, parking brake set
Facing uphill the car would roll back, so first gear resists that, the wheels turned out let a tire catch the curb, and the parking brake holds it.
-
25. Where is a U-turn generally the most reasonable choice?
Show answer
Answer B: At an intersection where it is permitted and you can see well both ways
A U-turn needs a legal place and a long clear view in both directions, which is why a permitted intersection with open sight lines is the usual choice.
-
26. May you stop in the striped triangle that separates an exit ramp from the freeway lanes?
Show answer
Answer A: No, it is not a lane and stopping there is dangerous
The striped gore area is not a travel lane or a shoulder, and a vehicle stopped there sits directly in the path of drivers correcting a late exit.
-
27. Where is signing of this kind normally placed along a freeway?
Show answer
Answer D: Ahead of the interchange and again at the exit, so a driver can reach the correct lane in time
Guide information for an interchange is repeated on the approach and at the ramp, because a driver who learns about the exit only at the last moment has no room left for a safe lane change.
-
28. You have strapped luggage to the roof rack for a long trip. What should you expect?
Show answer
Answer D: A higher center of gravity, so take the curves and lane changes gently
Weight on the roof raises the center of gravity and makes the vehicle lean and respond more slowly to steering.
-
29. A sign beside the signal reads STOP HERE ON RED. What does it tell you?
Show answer
Answer B: Stop at that point on red, not closer to the intersection
The sign marks the required stopping point, which is set back from the corner so that turning vehicles and sight lines are not blocked.
-
30. Why should you not rest your foot on the brake pedal as you drive?
Show answer
Answer D: The brake lights stay on and the drivers behind cannot read you
Resting on the pedal keeps the brake lights lit and wears the brakes, so following drivers stop believing your brake lights.
-
31. What must you be sure of before you pull out to pass on a two-lane road?
Show answer
Answer A: That the road ahead is clear far enough for the whole pass
You need enough clear road to pull out, pass and return before any oncoming vehicle arrives, and you must judge that distance before you start.
-
32. A vehicle coming toward you has drifted into your lane. What should you do?
Show answer
Answer D: Slow down, sound the horn, flash your lights and steer to the right if possible
Moving right gives the other driver space to recover and keeps you out of the lane they are most likely to return to. Braking reduces the force of any impact.
-
33. What is the safest way to pass a bicyclist on a road with two lanes going your way?
Show answer
Answer D: Change lanes completely, as you would for a car
A bicycle is entitled to the room a vehicle needs, and moving into the next lane gives the rider space to swerve around a drain or a pothole.
-
34. An upward-pointing pentagon with a yellow legend and border on a blue background is used as
Show answer
Answer D: a county route marker
The pentagon serves both the school warning series and county route markers, and the blue background with yellow legend identifies the county route version.
-
35. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
36. Why should cruise control be switched off on wet, snowy or icy roads?
Show answer
Answer B: It may keep feeding power to a wheel that has started to slip, and cancelling it costs you time
Cruise control holds a set speed regardless of grip, so it can add power just as a tire loses traction, and the extra step of cancelling it delays your response.
-
37. Besides a chemical test, what else supports an impaired driving charge?
Show answer
Answer B: The officer's observations of the driving and the driver
Weaving, slow responses, speech and balance observed by the officer are evidence in their own right, which is why a driver can be charged on behavior alone.
-
38. What is meant by keeping a space cushion?
Show answer
Answer C: Keeping open space on all sides of your vehicle so you always have somewhere to go
Open space ahead, behind and to the sides gives you time to react and an escape path when a hazard appears, which is the core idea of defensive driving.
-
39. Which of these is never a legal place to park?
Show answer
Answer C: In a crosswalk, on a sidewalk or within an intersection
Crosswalks, sidewalks and intersections must stay clear so that pedestrians can cross and drivers can see approaching traffic.
-
40. What happens if the liability signer for an Idaho driver under 18 withdraws consent?
Show answer
Answer A: The department cancels the driving credential
While the driver is under 18 the liability signer may withdraw consent at any time, and ITD then cancels the driving credential until the driver turns 18 or another acceptable signer is found.
