1. You are driving on a two-lane road approaching the crest of a hill. Where should you position your vehicle?
Show answer
Answer D: Toward the right side of your lane, in case an oncoming vehicle is over the center line
You cannot see what is beyond a crest, and oncoming drivers sometimes drift across the center. Keeping right and slowing gives you a margin.
-
2. How should you handle a prescription or over the counter medicine before driving?
Show answer
Answer D: Read the label and ask a pharmacist or doctor whether it affects driving
Many common medicines, including allergy and cold remedies, cause drowsiness or slowed reactions, and the label or a pharmacist can tell you whether driving is safe.
-
3. A person using a wheelchair is waiting to cross at a corner ahead. How should you treat that person?
Show answer
Answer B: As a pedestrian with the right of way at the crossing
A wheelchair or a mobility scooter user has the rights of a pedestrian, so yield the whole crossing and wait until the crossing is finished.
-
4. How should the inside rearview mirror be adjusted?
Show answer
Answer B: So you can see the entire rear window without moving your head
The inside mirror is for the view straight behind you. Framing the whole rear window from your normal seating position gives the widest useful view.
-
5. A vehicle in the lane beside you has stopped at a crosswalk. What should you do?
Show answer
Answer C: Stop as well, because that driver may be yielding to a pedestrian you cannot see
The stopped vehicle hides the crosswalk from you, and passing it is a leading cause of collisions with pedestrians who are already crossing.
-
6. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
7. The traffic signal is green, but the crossing lights on the tracks inside the intersection begin to flash. What must you do?
Show answer
Answer C: Stop clear of the tracks and wait, even though the signal is green
Active crossing warning devices outrank the green indication, so you stop short of the rails and wait until the warning stops.
-
8. The road is icy and visibility is poor, but you are driving at the posted speed limit. Is this acceptable?
Show answer
Answer A: No, because you may never drive faster than is safe for the conditions
Under the basic speed rule a driver must travel at a speed that is reasonable for the actual conditions, so a legal posted speed can still be an unlawful and unsafe speed.
-
9. A NO LEFT TURN sign carries a plaque reading 7 AM TO 9 AM MON TO FRI. What does the assembly mean?
Show answer
Answer A: The turn is banned only during those hours on those days
A time plaque limits the restriction to the periods shown, so outside those hours and days the left turn may be made normally.
-
10. You are turning right on a red light where that is permitted. What does the law require first?
Show answer
Answer B: A full stop, then yielding to traffic and pedestrians
A right turn on red is allowed only after stopping completely and giving way to everyone who has the green, including people in the crosswalk.
-
11. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?
Show answer
Answer B: Follow the signs and what you can see
A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.
-
12. How does alcohol change the time a driver needs to respond to a hazard?
Show answer
Answer A: It slows it, so stopping takes longer
Alcohol is a depressant that lengthens the time between seeing a hazard and acting on it, which adds directly to the distance needed to stop.
-
13. How does eating a large meal before drinking affect impairment?
Show answer
Answer D: It slows absorption but the alcohol still reaches the blood and impairs you
Food delays how quickly alcohol enters the bloodstream, which can make the peak arrive later, but all of the alcohol is eventually absorbed.
-
14. You have a green left-turn arrow but a pedestrian is still walking in the crosswalk you must cross. What should you do?
Show answer
Answer B: Wait until the crosswalk is clear before turning
A green arrow protects you from other vehicles, but it never removes the duty to yield to a person already in the crosswalk.
-
15. Besides school signing, which warning signs may also use a fluorescent yellow-green background?
Show answer
Answer C: Pedestrian and bicycle warning signs
Pedestrian crossing, bicycle and playground warning signs may use either the standard yellow or the fluorescent yellow-green background, which draws extra attention where people outside vehicles are present.
-
16. You face a red light at an intersection that has no stop line and no marked crosswalk. Where must you stop?
Show answer
Answer C: Before entering the intersection
With no line and no crosswalk, the stopping point is the near edge of the intersecting roadway, close enough to see cross traffic but clear of it.
-
17. What extra condition applies to an Idaho home-schooled applicant who needs proof of school compliance?
Show answer
Answer B: Enrollment in the home-education program for at least one school year
Idaho requires home-education students to have been enrolled in the program for at least one school year, unless they can document meeting the attendance requirement for the year before.
-
18. How can you tell that a child safety seat is installed tightly enough?
Show answer
Answer C: It moves less than an inch side to side or front to back at the belt path
A correctly installed seat is nearly immovable where the belt or lower anchors pass through it. Excess movement lets the child's body travel farther in a crash.
-
19. What does a NARROW BRIDGE warning sign tell a driver?
Show answer
Answer A: The bridge is tighter than the road leading up to it
A narrow bridge still carries both directions, but with much less clearance than the approaches, so drivers should slow and hold their lane position carefully.
-
20. 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.
-
21. Where designated and not otherwise posted, what is the maximum speed on Idaho urban interstate highways?
Show answer
Answer A: 65 miles per hour
Idaho allows up to 80 miles per hour on rural interstates where designated but holds urban interstates to 65 unless otherwise posted.
-
22. In most states, when are headlights required apart from times of poor visibility?
Show answer
Answer A: From about half an hour after sunset to half an hour before sunrise
Most states require lights from about half an hour after sunset until about half an hour before sunrise, and some simply say sunset to sunrise; lights are also required whenever visibility is poor.
-
23. You are behind a slow vehicle on a two-lane road and a marked passing lane begins a mile ahead. What is the sensible choice?
Show answer
Answer D: Wait for the passing lane rather than using the opposing lane
A passing lane lets you overtake without ever entering the lane used by oncoming traffic, which is far safer than a pass a minute earlier.
-
24. A traffic signal ahead is showing a flashing red light. What does it require?
Show answer
Answer C: Stop completely, then go when the way is clear, as at a stop sign
A flashing red light has the same meaning as a stop sign: stop completely, yield to traffic and pedestrians, then proceed when it is safe.
-
25. Which facility does this sign direct a traveler toward?
Show answer
Answer B: A hospital offering emergency care
This is the standard marker for medical care, used to lead a traveler to a hospital where emergency treatment is available.
-
26. During Idaho's supervised instruction period, where must the supervising driver sit?
Show answer
Answer A: In the front seat beside the driver, and no other passengers may sit in front
The supervising driver must be a licensed driver at least 21 years old occupying the front seat beside the learner, and no other passengers are allowed in the front seat.
-
27. Is it acceptable to leave your vehicle across the entrance of an alley for a short time?
Show answer
Answer A: No, the entrance must stay clear at all times
Blocking an alley entrance traps the vehicles inside and can keep emergency services out, so it is prohibited however brief the stop.
-
28. Another driver is behaving aggressively toward you. What should you do?
Show answer
Answer D: Avoid eye contact, give them room to go on their way and do not respond to provocation
Responding to an aggressive driver escalates the conflict, while creating distance and refusing to engage takes you out of the situation. Report serious threats once you can do so safely.
-
29. What change in the road does this sign announce?
Show answer
Answer B: The two directions of travel are about to be separated, and the driver must keep to the right of the separation
Ahead the roadway splits into separate one-way roadways on either side of a median, so the driver stays to the right of the divider and no longer meets oncoming vehicles.
-
30. Under Idaho's Graduated Driver's License program, how long must a supervised instruction period last before a driver under 17 may be licensed?
Show answer
Answer B: At least six months, violation free
Idaho requires a minimum six-month, violation-free supervised instruction period, and any traffic conviction during that period cancels the permit and restarts the six months.
-
31. What habit prevents the hood from flying up while you are driving?
Show answer
Answer D: Press the hood down at the front and check that the latch has caught
Most hoods fly up because they were left on the safety catch, so check that the main latch is fully closed after any work under the hood.
-
32. What must a driver be ready for beyond this sign?
Show answer
Answer C: Vehicles approaching from the opposite direction in the next lane over
The separation between the two directions runs out, so from that point oncoming vehicles share the same pavement and the driver has to keep right.
-
33. A child has outgrown the rear-facing seat. What comes next?
Show answer
Answer D: A forward-facing seat with a harness, used up to its own stated limits
The stages run rear facing, then forward facing with a harness, then a booster, then the adult belt alone.
-
34. How should tire pressure be checked and set?
Show answer
Answer B: When the tires are cold, set to the pressure specified by the vehicle manufacturer
Driving heats the air and raises the reading, and the sidewall number is a maximum rather than a recommendation, so check cold and use the figure on the vehicle placard or in the owner's manual.
-
35. Which part of the space around your vehicle can you control best?
Show answer
Answer A: The space ahead of you
You choose your own following distance, so the gap in front is the space you truly control and the one that gives you time to react.
-
36. A trailer that sways badly at speed is often loaded the wrong way. What is the usual fault?
Show answer
Answer A: Too much of the load sits behind the trailer axle
Weight behind the axle lightens the hitch and lets the trailer wag the vehicle. Most of the load should sit ahead of the axle to keep weight on the hitch.
-
37. Another driver cuts you off and you feel your temper rising. What should you do?
Show answer
Answer A: Take a breath, drop back and let it go, because the whole trip matters more
Retaliation turns a moment of bad driving into a crash, and dropping back costs you only a few seconds.
-
38. The red lights on a stopped school bus go out and the bus begins to move away. What should you do?
Show answer
Answer B: Move off slowly and keep watching for children near the road
Children who have just left the bus may still be near the roadway or crossing behind it, so pull away gently and keep looking for them.
-
39. Apart from other vehicles, who else must a driver let go first at this sign?
Show answer
Answer A: Pedestrians and cyclists already in or entering the crossing
The duty to give way covers every road user who has the right of way at that point, including people walking or cycling across the driver's path.
-
40. In a work zone, the flagger's instructions conflict with the pavement markings still visible on the road. Which do you follow?
Show answer
Answer B: The flagger, because a person directing traffic outranks the markings
An authorized flagger controlling a temporary traffic control zone overrides signs, signals and markings, and drivers must obey the flagger's signals.
