1. Loose items slide around your car and rattle every time you brake. What is the answer?
Show answer
Answer C: Secure them before you start driving
Sliding objects pull your attention and can roll under the pedals, so stow them in the trunk or wedge them before the trip rather than chasing them during it.
-
2. How long must an Idaho driver carry proof of financial responsibility after a first violation of the no-insurance laws?
Show answer
Answer D: One year
A first no-insurance offense requires one year of proof of financial responsibility in Idaho, while a second offense within five years requires three years.
-
3. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
4. Idaho equipment law sets a stopping standard for foot brakes. What is it?
Show answer
Answer B: A stop from 20 miles per hour on dry pavement within 25 feet
Idaho requires foot brakes to stop a vehicle traveling 20 miles per hour on dry pavement within 25 feet, while the emergency or parking brake must do it within 55 feet.
-
5. On a long, straight highway you feel your attention fading. What helps you stay alert?
Show answer
Answer A: Keep your eyes moving, scan mirrors and signs, and take regular breaks
Staring at one point brings on highway hypnosis. Active scanning keeps the mind engaged, and a break every couple of hours restores alertness.
-
6. What is the correct order of steps as you finish parking an automatic on a grade?
Show answer
Answer C: Turn the wheels, set the parking brake, then select park
Setting the parking brake before shifting into park lets the brake take the load, instead of leaving the whole weight of the car on the parking pawl.
-
7. 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.
-
8. A snow squall cuts visibility to almost nothing while you are on a highway. What must you not do?
Show answer
Answer D: Stop in a travel lane and wait for the squall to blow through
A vehicle stopped in a lane in a whiteout is invisible until someone hits it. Slow gradually and keep moving until you can leave the roadway completely.
-
9. A short driver cannot get ten inches between the chest and the steering wheel airbag. What is the answer?
Show answer
Answer D: Move the seat back and tilt the wheel downward, or fit pedal extenders
Distance from the airbag is gained by moving the seat back and aiming the wheel at the chest, using pedal extenders if the pedals are then out of reach.
-
10. A signal stands part way up a freeway entrance ramp and turns green briefly again and again. How many vehicles does such a signal normally release on each green?
Show answer
Answer A: One for each lane of the ramp
A ramp control signal releases a single vehicle per lane on each green so that vehicles reach the merge one at a time instead of in a bunch.
-
11. Why do bridges and overpasses deserve extra caution when temperatures are near freezing?
Show answer
Answer A: They lose heat from above and below, so they ice over before the surrounding road
A bridge deck is exposed to cold air on both surfaces and has no ground beneath it to hold heat, so ice can form there while the connecting road is still only wet.
-
12. You are turning left from a one-way street onto another one-way street. Which lane should you use?
Show answer
Answer B: Turn from the far left lane into the far left lane of the new street
The general turning rule is to turn from the lane nearest the direction of the turn into the nearest lane of the new roadway, which on a one-way to one-way left turn means far left to far left.
-
13. You back into an unattended parked car in a lot and cause visible damage. What must you do?
Show answer
Answer A: Try to find the owner, or leave a note with your name and contact details, and report the crash
Hitting an unattended vehicle carries the same duties as any crash. Leaving without identifying yourself is a hit-and-run offense.
-
14. Roughly how far does a vehicle travel at 55 mph during the few seconds a driver spends reading a text message?
Show answer
Answer D: About the length of a football field
Sending or reading a message takes the eyes off the road for about five seconds, which at 55 mph covers roughly the length of a football field with nobody watching the road.
-
15. You are waiting to pull out of a driveway when a bicyclist comes along the bike lane in front of you. What must you do?
Show answer
Answer D: Wait until the bicyclist has gone past
A driver leaving a driveway yields to everything already on the road, and a bike lane is part of the roadway.
-
16. The green arrow protecting your turn changes to a steady yellow arrow. What is it telling you?
Show answer
Answer A: The protected turn is ending and you should prepare to stop
A steady yellow arrow warns that the arrow movement is being terminated and that a red indication will follow.
-
17. A hands free phone conversation is which kind of distraction?
Show answer
Answer C: Cognitive, because your mind leaves the road
Hands free equipment removes the manual and visual parts of a call but not the mental load, and it is the mental load that makes a driver miss hazards.
-
18. A driver extends the left arm out the window and bends it upward at the elbow. What does this signal mean?
Show answer
Answer B: A right turn
The left arm bent upward at the elbow is the standard hand signal for a right turn.
-
19. A freeway sign reads BUSES ONLY ON SHOULDER 6 AM TO 9 AM. Who may drive on the shoulder then?
Show answer
Answer A: Only the vehicles named on the sign, during the hours shown
Shoulder running is granted by the sign to the class of vehicle and the hours the sign names, and it does not turn the shoulder into a general travel lane.
-
20. Which trailer lights must work before you drive away?
Show answer
Answer B: The tail lights, brake lights and turn signals
The trailer hides the vehicle lights from anyone behind, so its own tail, brake and turn signals have to work before you move.
-
21. 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.
-
22. You are making a legal U-turn at an intersection. Who has the right of way?
Show answer
Answer C: Everyone else, until your turn is complete
A U-turn crosses several paths at once, so you yield to oncoming vehicles, to crossing traffic and to pedestrians before starting it.
-
23. Where are children in the greatest danger around a school bus?
Show answer
Answer B: In the roadway right around the bus, especially in front
The danger zone is the band of roadway around the bus where the driver's view is poorest, and children crossing in front of the bus are hardest to see.
-
24. In Idaho, 24 or more points in any 36-month period results in what?
Show answer
Answer A: A six-month suspension
The top band of Idaho's point system, 24 or more points in any 36 months, carries a six-month suspension.
-
25. You are following another vehicle down a long, steep grade. What should you do about the gap?
Show answer
Answer D: Make it longer, because both of you need more room to stop
Everything takes longer to stop on a downgrade, including the vehicle ahead, so the gap that works on the flat is no longer enough.
-
26. You are turning left from a two-way street onto another two-way street. Where should you begin and end the turn?
Show answer
Answer B: Begin in the lane just right of the center line and finish just right of the center line of the new street
You approach a left turn from the lane closest to the center line and enter the new roadway just to the right of its center line, which keeps you clear of oncoming traffic.
-
27. You are starting from a stop on a snowy, icy street and the drive wheels begin to spin. What should you do?
Show answer
Answer C: Ease off the accelerator and start again more gently
Spinning tires polish the surface and dig in. Very gentle pressure on the accelerator, and a higher gear if you have one, gives the tires the best chance to grip.
-
28. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
-
29. The curb ahead is signed as a bus stop. May you wait there with your vehicle?
Show answer
Answer C: No, the space must stay clear for buses
A bus stop must stay open so that a bus can reach the curb and let passengers on and off safely, so no other vehicle may occupy it.
-
30. An orange sign reads RIGHT LANE CLOSED AHEAD. What is the correct response?
Show answer
Answer A: Move left in good time and keep a steady pace
The sign is placed well before the taper so that drivers can merge smoothly rather than braking hard where the lane actually closes.
-
31. How should a lap and shoulder belt be positioned?
Show answer
Answer A: Lap belt low across the hips and shoulder belt across the chest and collarbone
The lap belt must bear against the strong pelvic bones rather than soft organs, and the shoulder belt must cross the rib cage and collarbone so crash forces spread over the skeleton.
-
32. You are approaching a sharp curve. When should you reduce your speed?
Show answer
Answer D: Before you enter the curve, so you can accelerate gently through it
Braking hard inside a curve uses up the traction that is already being demanded for cornering, so the slowing must be finished before you enter.
-
33. What do white lane lines painted between travel lanes indicate?
Show answer
Answer A: Traffic in the adjacent lane moves in the same direction as you
White markings separate lanes carrying traffic in the same direction and mark the right edge of the roadway.
-
34. You feel dizzy and get a headache while driving with the windows closed. What could be the cause and what should you do?
Show answer
Answer D: An exhaust leak letting carbon monoxide into the cabin, so open the windows and stop to get fresh air
Carbon monoxide is colorless and odorless, and headache, dizziness and drowsiness are early signs. Get fresh air at once and have the exhaust system inspected.
-
35. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
36. A bike lane on your right is marked with a dashed line for the last stretch before the corner. What does that dashed section allow you to do?
Show answer
Answer D: Merge into the bike lane after checking, and turn right from there
The dashed section is where drivers are meant to merge into the bike lane before turning, which puts cyclists behind the vehicle instead of beside it.
-
37. Yellow signs each showing one large black arrowhead, installed in a row along the outside of a curve, are
Show answer
Answer D: chevron alignment signs marking the change of direction of the curve
Chevron alignment signs are placed on the outside of a curve so that several are in view at once, letting the driver judge how sharply the road turns.
-
38. At roughly what speed can hydroplaning begin when a lot of water is lying on the road?
Show answer
Answer C: At speeds as low as about 35 mph
With enough water and less than perfect tread, a tire can start to ride on the water at around 35 mph, well below normal highway speeds.
-
39. Two solid white lines are painted between your lane and the lane beside it. What do they mean?
Show answer
Answer D: Crossing from one lane to the other is prohibited
Double solid white lines separate lanes of traffic going the same way and may not be crossed.
-
40. You are passing a line of slow traffic in the lane beside you and you notice a gap in that line ahead. What should you expect?
Show answer
Answer A: A vehicle may pull out of that gap into your lane
A gap in a slow line is an invitation to any driver waiting to turn out of a side street or to change lanes, and they are looking at the gap rather than at you.
