1. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
2. It is dusk and a jogger in dark clothing is running along the edge of the road. What should you do?
Show answer
Answer D: Slow down and scan the edges of the road
Dusk is the hardest light for spotting people, and dark clothing removes most of your warning, so lower speed and a careful scan of the roadsides are the answer.
-
3. About how far behind a tractor-trailer does the driver's rear blind spot reach?
Show answer
Answer C: Around 30 feet
The area behind a large truck is hidden for roughly 30 feet, so a driver tucked in there cannot be seen at all.
-
4. You need to reverse direction on a busy street. Which choice is usually safest?
Show answer
Answer D: Driving around the block and using the intersections instead
Going around the block uses normal turns at controlled intersections instead of stopping across live traffic lanes.
-
5. Why is passing another vehicle a bad idea in dense fog?
Show answer
Answer C: You cannot see far enough ahead to know the passing lane is clear
A pass needs a clear view of the road well beyond the vehicle you are overtaking, and fog takes exactly that away.
-
6. You are hosting a party and a guest who has been drinking wants to drive home. What should you do?
Show answer
Answer D: Stop serving and arrange a ride or a bed
Only time removes alcohol, so a host who wants to prevent a crash has to remove the driving, not try to speed up sobering that cannot be sped up.
-
7. What does an approved Idaho driver training program consist of?
Show answer
Answer A: 30 hours of classroom instruction, 6 hours of in-car observation and 6 hours of behind-the-wheel driving
Idaho requires 30 hours of classroom work, six hours observing other student drivers from inside the car and six hours of behind-the-wheel practice with an approved instructor.
-
8. How long should a glance at a mirror or an instrument take?
Show answer
Answer A: A brief glance of about a second, returning your eyes to the road at once
Checks should be quick flicks of the eyes. At highway speed, a few seconds with your eyes off the road covers a distance long enough for a hazard to appear.
-
9. Snow has covered the pavement markings on a two-lane road. How should a driver judge lane position?
Show answer
Answer B: By the tracks of other traffic and the roadside features
With the markings hidden, ruts left by earlier traffic, signs, poles and the line of the shoulder are the best clues to where the lane runs.
-
10. A yellow sign reading DEAD END is posted at the entrance to a street. What does it mean?
Show answer
Answer D: The street ends and there is no way through
A dead end street stops at its far end, so a driver who enters must come back out the same way.
-
11. You are driving through patchy fog on a highway. What should you be ready for?
Show answer
Answer B: Sudden dense banks where visibility drops within a few car lengths
Patchy fog can go from clear to nearly blind in a moment, so keep your speed low enough that a sudden bank does not leave you without room.
-
12. 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.
-
13. You have to leave a trailer parked on a slope. What extra step protects it?
Show answer
Answer D: Chock the trailer wheels as well as setting the brake
Chocks physically block the wheels, which is the only thing that still holds if a brake or a coupling lets go.
-
14. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with left-turn arrows painted in it. How may you use that lane?
Show answer
Answer A: Only to make a left turn or to prepare for one from either direction
That marking identifies a two-way left turn lane, which may only be used for left turns or to prepare for a left turn and never for travel or passing.
-
15. A wheel comes off your car while you are driving. What should you do?
Show answer
Answer A: Hold the wheel firmly, ease off the gas and steer gently to the shoulder
A firm grip and a gradual slowing keep the vehicle straight, while hard or sudden braking makes a damaged corner pull the car out of line.
-
16. A driver slows to walking pace at this sign, never stops rolling and eases into the intersection. How is that treated?
Show answer
Answer B: It is a violation, because the vehicle never came to a complete halt
What is required is a full halt with the wheels no longer turning, so slowing down, however carefully, does not satisfy it.
-
17. Should you drive with your hazard lights flashing while moving in fog?
Show answer
Answer A: No, they hide your turn signals and suggest you are stopped
Hazard lights on a moving vehicle tell other drivers you are stopped or disabled, and they cancel out your turn signals just when clarity matters most.
-
18. You realize you have just gone past your exit on a freeway. What should you do?
Show answer
Answer C: Carry on to the next exit and turn around there
A missed exit costs a few minutes, while backing up or cutting across the striped gore area puts you in the path of traffic that is not expecting it.
-
19. How does the blood alcohol standard for a driver operating a commercial vehicle compare with the one for a car driver?
Show answer
Answer D: It is lower, set at 0.04
Commercial drivers are held to a stricter standard of 0.04 because of the size of their vehicles and the risk they carry.
-
20. What does Idaho law allow a bicyclist to do at a stop sign?
Show answer
Answer D: Slow, yield the right of way and then proceed without a complete stop
Idaho does not require bicyclists to come to a complete stop at a stop sign; they must yield to vehicles in or approaching the intersection and then proceed with caution.
-
21. You have stopped at a stop line but parked cars hide the cross street. What comes next?
Show answer
Answer C: Edge forward to where you can see, stopping again if needed
The legal stop at the line is only the first stop; you then move up slowly to a point where you can see, and stop again if traffic requires it.
-
22. Your vehicle has a backup camera. What is the right way to use it?
Show answer
Answer C: Use it as an aid, but still turn and look behind you
A camera has a limited field of view and can be dirty or wet, so it supplements looking over your shoulder and using the mirrors rather than replacing them.
-
23. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
24. An angry driver is following you closely and gesturing at you. What is the safe response?
Show answer
Answer B: Drive to a police station or to a busy public place and call for help
Never stop to confront an aggressive driver and never lead one home; go somewhere public and get the police involved.
-
25. You reach a one-lane bridge and a vehicle is already partway across it coming toward you. What should you do?
Show answer
Answer D: Stop before the bridge and let it come through
A vehicle already on a one-lane bridge has the right of way, and the driver who has not yet entered waits at the approach.
-
26. On which Idaho road may a driver continue past a stopped school bus that is displaying flashing red lights?
Show answer
Answer D: A highway of four or more lanes with two lanes each way, traveling the other way
Idaho requires traffic to stop for a school bus showing flashing red lights, except for drivers traveling in the opposite direction on a highway of four or more lanes with two lanes going each way.
-
27. The light ahead is green, but traffic beyond the intersection is backed up so far that you could not clear it. What is the correct action?
Show answer
Answer D: Wait behind the stop line until there is room on the far side
Entering an intersection you cannot clear blocks cross traffic and pedestrians, so you should hold your position until space opens on the other side.
-
28. Two drivers each have three drinks, one over three hours and one in half an hour. What is the difference?
Show answer
Answer C: The fast drinker reaches a higher peak level
The liver removes alcohol at a steady rate, so drinking faster than the body can clear it pushes the blood alcohol level much higher.
-
29. Idaho bars a U-turn where approaching vehicles cannot see you within what distance?
Show answer
Answer B: 500 feet
Idaho prohibits U-turns on any curve, near the crest of a hill or anywhere the vehicle cannot be seen by approaching traffic from either direction within 500 feet.
-
30. The signal ahead turns yellow while you are approaching it. What does the yellow light mean?
Show answer
Answer C: The red is coming; stop if you can do so safely
A steady yellow warns that the red is next. Stop if you can do so safely; enter the intersection only when stopping would be dangerous.
-
31. Which surfaces usually offer less grip than the pavement around them when wet?
Show answer
Answer B: Painted markings, metal plates and bridge decks
Paint, steel and bridge decks all shed grip when wet or cold, so brake before you reach them rather than on top of them.
-
32. How close to a fire hydrant may a vehicle be parked in Idaho?
Show answer
Answer B: No closer than 15 feet
Idaho prohibits parking within 15 feet of a fire hydrant, within 20 feet of a crosswalk and within 30 feet of a stop sign, yield sign or traffic signal.
-
33. 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.
-
34. What must happen to an applicant's cell phone during an Idaho skills test?
Show answer
Answer D: It must be turned off
ITD requires cell phones and other electronic devices to be turned off during the Class D skills test.
-
35. On an overhead guide sign, the small exit number panel sits above the left-hand end rather than the right. What does that placement tell you?
Show answer
Answer A: The exit leaves from the left side of the roadway
The exit number plaque is placed on the side from which the ramp leaves, which gives advance notice of the unusual left-hand exit.
-
36. You turn from asphalt onto a loose gravel road. What should you do about your speed?
Show answer
Answer D: Lower it, since grip is reduced and stopping takes longer
Loose gravel gives far less grip than pavement, so speed must come down for both steering and stopping.
-
37. Which combination best reduces the chance of hydroplaning?
Show answer
Answer D: Good tread depth, correct tire pressure and lower speed in the rain
Tread channels water away, correct pressure keeps the tire's shape, and lower speed gives the tire time to push water aside. Hydroplaning can begin at surprisingly modest speeds.
-
38. An arrow panel at a work zone displays a flashing arrow pointing to the left. What does it require?
Show answer
Answer C: Move out of the closed lane into the lane on the left
A flashing or sequential arrow on an arrow panel directs traffic out of a closed lane and into the lane the arrow points to.
-
39. On an unlit road, about how far ahead do high beams normally let you see?
Show answer
Answer D: About 350 to 500 feet ahead of the vehicle
High beams light roughly 350 to 500 feet of road and low beams far less, which is why night speeds have to be chosen around the beam, not the limit.
-
40. A yellow diamond on an exit ramp shows a truck tipping over onto two wheels. Which drivers does it concern most?
Show answer
Answer D: Those in tall vehicles carrying a high load
The truck rollover sign warns that the curve can overturn a vehicle with a high center of gravity, so such drivers must slow well below the normal ramp speed.
