1. You and a driver coming from the opposite direction reach a four-way stop at the same time and you are both going straight ahead. What happens next?
Show answer
Answer D: Both of you may move off together, because your paths do not cross each other
Opposing vehicles that are both going straight do not cross paths, so they can move off together once the intersection is clear.
-
2. The stability control warning light flashes while you are driving through a curve. What does it mean?
Show answer
Answer A: The system is actively working to keep the vehicle under control, so slow down
A flashing stability control light means the system is braking individual wheels because you are near the limit of grip. Ease off and drive more gently.
-
3. A yellow horizontal rectangular sign showing one large arrow pointing left or right, facing traffic on the far side of a sharp bend, tells the driver
Show answer
Answer C: which way the roadway turns at that point
The large arrow sign is mounted on the outside of a sharp change in alignment so that a driver approaching head on immediately sees which way the road goes.
-
4. What is wrong with steering through a turn using the palm of one hand on the wheel?
Show answer
Answer D: You have less control and cannot correct quickly if something goes wrong
One-handed palming gives poor leverage and slow response. Use hand-to-hand or hand-over-hand steering with both hands so you can react instantly.
-
5. A lane along the right edge is set off by a solid white line and marked with a bicycle symbol. How should a driver treat it?
Show answer
Answer B: Stay out of it except for the short distance needed to turn or cross where that is allowed
A marked bicycle lane is set aside for bicycle traffic, and motor vehicles may enter it only briefly where turning or crossing is permitted.
-
6. A piece of farm machinery ahead of you is wider than its own lane. What should you do?
Show answer
Answer C: Hold back until you can see far enough to pass safely
Wide equipment leaves no gap inside the lane and may use part of the other side, so a pass needs a long clear view of the road ahead.
-
7. You have just passed a vehicle on a two-lane road. When may you return to your lane?
Show answer
Answer B: When you can see the whole vehicle in your inside mirror
Seeing the entire vehicle you passed in your rearview mirror shows there is room to pull back in without cutting it off.
-
8. Which vehicle is most affected by a strong side wind?
Show answer
Answer D: A van or a car towing a tall trailer
Wind pushes against the side area of a vehicle, so tall boxy shapes and trailers are moved far more than low heavy ones.
-
9. Well before an intersection, an overhead sign shows a diagram of the lanes with an arrow above each one. What is its purpose?
Show answer
Answer C: To let drivers pick the correct lane in good time
Advance intersection lane control signs display the lane assignment far enough back that drivers can move over calmly instead of at the last moment.
-
10. The passenger-side mirror on most vehicles is convex. What does this mean for the driver?
Show answer
Answer D: Vehicles in that mirror are closer than they appear
A convex mirror gives a wider view but shrinks what it shows, so a vehicle looks smaller and therefore farther away than it really is. Allow for this before changing lanes.
-
11. A driver ahead brakes for no reason you can see, again and again. What should you do?
Show answer
Answer B: Increase your following distance and be ready for yet another stop
Unexplained braking tells you the driver is unsure or distracted, so the safe answer is more room, not less.
-
12. You are behind a snow plow working on a highway. What is the correct way to drive?
Show answer
Answer C: Stay well back and do not try to pass it
A plow throws snow, runs wider than its body and works on the poor surface ahead of it, so the cleared road behind it is the safest place to be.
-
13. A SHOULDER DROP OFF sign warns that
Show answer
Answer B: there is a step down from the pavement to the shoulder
The sign is used where the edge of the pavement stands several inches above the shoulder, which can grab a wheel and pull the vehicle sideways.
-
14. Why does a heavier vehicle need more room to stop than a light one from the same speed?
Show answer
Answer B: Because there is more mass in motion for the tires to slow down
More mass means more energy at the same speed, and the brakes and tires need more distance to get rid of it.
-
15. Your car is sinking after leaving the road into deep water and two children are in the back. In what order should you act?
Show answer
Answer D: Free yourself from the belt first, then release the children, the oldest one first
You cannot help anyone while you are still belted in, and the oldest child released first needs the least help getting out.
-
16. A sign reads END SCHOOL ZONE. What does it tell a driver?
Show answer
Answer A: The regular limit for that road applies again
An end of restriction sign marks the downstream limit of a special zone, after which the ordinary speed limit for that road governs again.
-
17. The red oil pressure warning light comes on while you are driving. What should you do?
Show answer
Answer C: Pull over safely as soon as possible and shut off the engine
Loss of oil pressure means the engine is no longer being lubricated and can be destroyed within minutes. Stop, shut down and check before restarting.
-
18. The added lane warning sign tells a driver that
Show answer
Answer A: an extra lane begins ahead, so entering traffic does not have to merge into an existing lane
Where a lane is added, traffic entering the roadway gets a lane of its own, so merging is not required, although drivers should still watch the vehicles beside them.
-
19. An officer directing traffic faces you and holds one hand up with the open palm toward your vehicle. What does the gesture mean?
Show answer
Answer D: Stop before reaching the officer
A raised open palm shown toward a driver is the standard signal to stop.
-
20. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
21. You are in the open lane where another lane is merging into yours. What is your part in the merge?
Show answer
Answer A: Keep a steady speed and leave a gap for one vehicle to come in
A merge works when each driver in the through lane lets one vehicle in, which keeps both lines moving instead of stopping them both.
-
22. What does Idaho law say about entering an intersection while a funeral procession is passing through it?
Show answer
Answer B: You may not enter unless you can do so without crossing the path of the procession
Idaho gives funeral processions the right of way, and a driver may not enter the intersection regardless of the color of the light unless it can be done without crossing the procession's path.
-
23. Where should you be looking as you back into a parallel parking space?
Show answer
Answer B: Over your shoulder through the rear window, glancing all around
Mirrors and cameras leave blind areas, so turn and look through the rear window while checking the front of your car and both sides as it swings.
-
24. What is the recommended minimum distance between the driver's breastbone and the center of the steering wheel air bag cover?
Show answer
Answer C: About 10 inches
An air bag inflates extremely fast, and keeping that much space lets it deploy fully before it reaches the driver, which is why the seat should be moved back as far as still allows comfortable control of the pedals.
-
25. What is the best way to handle the radio, the music player and the climate controls on a trip?
Show answer
Answer B: Set them before you start driving and let a passenger handle changes
Fiddling with controls takes eyes and hands off the driving task. Setting them before you move and letting a passenger make later changes removes the distraction entirely.
-
26. 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.
-
27. What does this sign require of the driver?
Show answer
Answer D: Reducing speed and being ready to stop at the intersection ahead
The advance notice asks the driver to slow and be ready to stop, while whether a stop is actually needed depends on the indication displayed on arrival.
-
28. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
29. In a normal signal cycle, what comes after a steady red indication?
Show answer
Answer A: A green indication that starts the next movement
Yellow is a warning that a movement is ending, so it never precedes a green; a red is followed by a green or a green arrow.
-
30. Your car has side curtain airbags. What should you avoid doing?
Show answer
Answer B: Resting your head against the window or the door pillar
A side airbag deploys from the pillar or roof rail, so a head leaning against that area is directly in its path.
-
31. Where is this sign normally installed?
Show answer
Answer A: At an island or other obstruction in the roadway, to show which side traffic must take
It is placed at a divider, island or fixed obstruction so that drivers approaching it know without hesitating which side to pass on.
-
32. You are waiting to turn left and a motorcycle is approaching from the opposite direction. Why should you take extra care judging its speed and distance?
Show answer
Answer A: Its small size makes it look farther away and slower than it really is
A motorcycle's narrow profile fools the eye, so drivers often misjudge how soon it will arrive. Left turns across an oncoming motorcycle are a leading cause of rider deaths.
-
33. What suspension follows a first failure of an evidentiary test under Idaho's administrative license suspension?
Show answer
Answer B: 90 days, with absolutely no driving privileges during the first 30 days
A first failed evidentiary test brings a 90-day administrative suspension, and the opening 30 days of it allow no driving privileges of any kind.
-
34. What is the main limit of stability and traction control systems?
Show answer
Answer B: They cannot create grip that the tires and the road do not have
These systems manage the grip that exists. If you enter a curve too fast for the surface, no amount of electronics will hold the vehicle on the road.
-
35. Two lanes at the corner are marked for right turns. What does that require of you?
Show answer
Answer A: Keep your own lane through the turn and into the matching new lane
Dual turn lanes work only if each vehicle stays in its own lane all the way round and finishes in the corresponding lane of the new street.
-
36. In slow summer traffic the temperature gauge climbs into the red. What should you do first?
Show answer
Answer A: Turn off the air conditioner and turn on the heater to draw heat from the engine
The heater core acts as an extra radiator, and shutting off the air conditioner reduces engine load. If the gauge keeps climbing, pull over and shut off the engine, and never open a hot radiator cap.
-
37. How should you use your mirrors while another vehicle overtakes you on a multilane road?
Show answer
Answer C: Follow it from the inside mirror to the side mirror and then to your own view
Handing the vehicle from one mirror to the next keeps it in sight through the blind spot instead of losing it there.
-
38. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
39. Which sign tells you that the vehicles ahead are part of a funeral procession?
Show answer
Answer C: Headlights burning in daylight, with small flags or markers on the vehicles
Processions are normally identified by daytime headlights, hazard lights and flags or windshield markers, not by emergency lights or sirens.
-
40. How do extra passengers affect a driver, especially a new one?
Show answer
Answer A: They increase the chance of distraction and of crashes
Conversation, laughter and horseplay pull a driver's attention away from the road. Crash risk for young drivers rises with each additional passenger.
