1. Besides the traffic behind you, what else must you check before moving into the next lane?
Show answer
Answer D: That there is room ahead in the new lane for your normal following distance
Moving into a gap that is too short leaves you tailgating the vehicle ahead with a vehicle close behind you.
-
2. Why should you stay out of an intersection you cannot clear, even on a green light?
Show answer
Answer B: Because you would block cross traffic when their signal turns green
A vehicle stranded in the intersection blocks the cross street when its light turns green, which stalls the whole junction and traps emergency vehicles.
-
3. You are leaving a freeway at an exit that has a deceleration lane. Where should you slow down?
Show answer
Answer C: After you have moved fully into the exit lane
Braking in a through lane surprises the traffic behind you, so you move into the exit lane at highway speed and then slow down inside it.
-
4. Does Idaho require an annual vehicle safety inspection?
Show answer
Answer B: No, although an officer may cite a vehicle that is unsafe or ill equipped
Idaho has no annual safety inspection requirement, but an officer who finds a vehicle unsafe or lacking proper equipment may issue a citation.
-
5. You are in a passing zone that continues over the crest of a hill ahead. May you start a pass?
Show answer
Answer B: Only if you can finish it well before the crest
Beyond the crest you cannot see oncoming traffic, so any part of the pass that happens there is being made blind.
-
6. The crossbuck, formed by two rectangular arms crossed in an X, is placed
Show answer
Answer D: on each highway approach to a railroad grade crossing
The crossbuck marks the location of a highway-rail grade crossing and is required on each highway approach to that crossing.
-
7. Why is texting considered one of the most dangerous distractions?
Show answer
Answer B: It combines visual, manual and cognitive distraction at the same time
Reading or writing a message takes your eyes off the road, at least one hand off the controls and your attention off driving simultaneously.
-
8. What is the correct technique for backing a vehicle straight?
Show answer
Answer B: Check behind the vehicle before getting in, then turn and look through the rear window while backing slowly
Mirrors and cameras leave gaps close to the vehicle, so walk behind it first, then turn in your seat for a direct view and keep the speed low enough to stop instantly.
-
9. An oncoming driver flashes their headlights while you are waiting to turn left. What should you do?
Show answer
Answer D: Judge the situation yourself, since the flash may mean something else
A flash is not a legal signal and may mean many things, so the decision to turn stays yours and must be based on what you can see.
-
10. Why is being thrown out of a vehicle in a crash so dangerous?
Show answer
Answer C: Because you strike the road or other objects at high speed, and rarely survive
Ejection is one of the deadliest outcomes of a crash, and a fastened belt is what keeps a person inside the vehicle.
-
11. It is dark, it is raining and you are towing a trailer. How should you set your following gap?
Show answer
Answer B: Add extra seconds for each condition, well beyond three
Each factor that lengthens your stopping distance or shortens your view calls for another second or more, and they add up when several occur together.
-
12. After a suspension for a serious offense such as reckless driving or driving under the influence, how long must an Idaho driver provide proof of financial responsibility?
Show answer
Answer B: Three years
Idaho requires three years of proof of financial responsibility, in the form of an SR-22 certificate from the insurer, after certain serious offenses.
-
13. On the Idaho skills test, how many repetitions of the same scored error count as a critical driving error?
Show answer
Answer D: Five of the same skill
Idaho calls this a habitual violation: missing the same scored skill five times is a critical driving error and ends the test immediately in a fail.
-
14. The trapezoid sign shape is associated with
Show answer
Answer C: recreational and cultural interest area signing
The trapezoid is used for recreational and cultural interest area guide signs and for national forest route markers.
-
15. What do zero tolerance laws mean for a driver who is under 21?
Show answer
Answer B: They commit a violation at an alcohol level far below the adult limit
Drivers under 21 may not legally drink, so every state sets a limit far below the adult one and treats even a trace reading as a violation. The exact figure is set by each state, and the penalty usually includes losing the license.
-
16. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
17. You and an opposing driver reach a four-way stop at the same time and both of you are turning right. What should happen?
Show answer
Answer C: Both may turn at the same time into their own lanes
Two opposing right turns take drivers into different lanes without crossing, so both can proceed together once pedestrians are clear.
-
18. A yellow sign reads SOFT SHOULDER. What is it telling you?
Show answer
Answer C: The shoulder may not carry the weight of a vehicle
A soft shoulder is unpaved and can let a wheel sink, so a driver who leaves the pavement there may lose control or become stuck.
-
19. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
20. What does a posted speed limit sign represent?
Show answer
Answer B: The maximum speed permitted under ideal conditions
A speed limit is an upper limit that assumes good weather, good visibility and light traffic, so the safe speed is often lower than the posted figure.
-
21. On Idaho roads that are not interstates, not state highways and not in a residential, business or urban district, what does the law allow unless otherwise posted?
Show answer
Answer D: From 55 miles per hour up to 70 miles per hour
The Idaho handbook allows 55 miles per hour up to 70 in other locations unless a different limit is posted.
-
22. You are about to pass a large truck on a two-lane highway. Which practice is correct?
Show answer
Answer A: Finish the pass without delay and expect wind turbulence beside the truck
Lingering beside a truck keeps you in its blind spot and exposes you to air turbulence. Pass on the left, keep moving, and move back only when you can see the whole truck in your mirror.
-
23. You come around a bend and find loose sand spread across your lane. What should you do?
Show answer
Answer D: Ease off the gas, avoid sudden braking or steering, and keep straight
Loose material acts like ball bearings under the tires; smooth inputs preserve what little grip remains, while sudden braking or steering breaks it.
-
24. A pedestrian is waiting to cross ahead of you and you have slowed down. What helps most?
Show answer
Answer D: Making eye contact, so that you both know you have seen each other
Eye contact confirms that you have seen each other; waving someone across can send them into the path of another vehicle.
-
25. You are driving through a neighborhood where several children are riding bicycles. What should you do?
Show answer
Answer C: Slow down and expect sudden, unpredictable moves
Young riders lack the judgment and the mirror habits of adults and may swerve or cross without looking, so lower speed is your only reliable margin.
-
26. Lights set into the pavement along both edges of a crosswalk start to flash yellow as you approach. What do they tell you?
Show answer
Answer D: Someone is crossing and has to be given way
In-roadway warning lights flash only when a pedestrian activates the crossing, so a flashing pattern means somebody is in or entering the crosswalk.
-
27. Children are playing close to the edge of a residential street. What is the right speed choice?
Show answer
Answer D: Well below the limit, slow enough to stop for a sudden dash
Children can step out without warning, so the safe speed is the one that lets you stop within the distance you can see to be clear.
-
28. You have passed a large truck and want to move back into its lane. What should you see first?
Show answer
Answer B: Both of its headlights in your rear-view mirror
Seeing both headlights in your mirror means you are far enough ahead to be out of the truck's front no-zone before you move over.
-
29. You have started to pass and you see the no-passing zone beginning ahead. What should you do?
Show answer
Answer D: Ease off, drop back and return to your own lane
A pass must be completed before the no-passing zone starts. If it will not fit, abandon it and slot back in behind.
-
30. What is the correct relationship between air bags and seat belts?
Show answer
Answer B: Air bags are designed to work together with seat belts, not instead of them
An air bag is a supplemental restraint that cushions one impact, while the belt keeps you in position so the bag can work and protects you in rollovers and secondary impacts.
-
31. A live power line is lying on your car and the car has caught fire, so you must get out. How should you leave it?
Show answer
Answer D: Jump clear without touching the car and ground at once, then shuffle away
Touching the vehicle and the ground together makes you the path to earth, and long strides can bridge the voltage spread through the ground.
-
32. Why are sign shapes and colors standardized across the whole country?
Show answer
Answer D: So a driver knows the kind of message before reading it
Uniform shapes and colors let a driver classify a sign as regulatory, warning or guide from a distance, before the legend can be read.
-
33. The circular sign shape is reserved for which warning?
Show answer
Answer C: Advance warning of a highway-rail grade crossing
A round yellow sign with a black X and the letters RR is the grade crossing advance warning sign, and the circular outline is used for no other message.
-
34. A city transit bus ahead of you has stopped at the curb with its passenger door open. What does the law require of you?
Show answer
Answer D: Nothing special, but pass slowly and watch for people
The mandatory stop applies to a school bus showing red flashing lights, not to a transit bus, though a careful driver still slows for crossing passengers.
-
35. Your green left-turn arrow goes out and a steady green ball stays lit. What may you do?
Show answer
Answer A: Continue turning left, but only after yielding to oncoming traffic
When the arrow ends and a green ball remains, the turn changes from protected to permissive, so it is still allowed but oncoming traffic goes first.
-
36. What should you do with the key and your belongings when you leave the vehicle in a public lot?
Show answer
Answer D: Take the key with you, lock up and put valuables out of sight
Most vehicle thefts are opportunistic: a key left behind or a bag in plain view is the invitation.
-
37. The vehicle in front of you has stopped and is waiting to turn left, and there is a paved shoulder to the right. May you use it to get by?
Show answer
Answer D: No, in most states a pass may not be made by leaving the paved travel lanes
Passing on the right is normally lawful only inside the marked travel lanes, and most states prohibit driving onto the shoulder to get around a turning vehicle; the few states that allow it attach strict conditions.
-
38. You notice that the driver ahead of you is holding a phone to the ear. What should you do?
Show answer
Answer C: Assume slower reactions and leave extra space, or else hold back
A driver on the phone reacts late and misses things, so the safe response is distance rather than a lesson.
-
39. Beyond the point this sign refers to, which movement becomes unlawful?
Show answer
Answer D: Driving on the far side of the separation, against the flow
Once the two directions are separated, each roadway carries one-way traffic, so crossing to the other side means driving into oncoming vehicles.
-
40. How should your speed behave while you move from one lane into the next?
Show answer
Answer C: Keep it steady or adjust it smoothly to match the traffic in the new lane
A lane change works best as a smooth movement at the speed of the lane you are joining, since sudden braking or acceleration surprises the drivers around you.
