1. A white regulatory sign near a state line reads BUCKLE UP IT IS THE LAW. What is it doing?
Show answer
Answer A: Reminding occupants that belt use is required
The safety belt sign restates a law that already applies, and it is usually placed where drivers enter a state or a long rural stretch.
-
2. You are at a red light where right turns on red are allowed, you cannot see clearly, and the driver behind sounds the horn. What should you do?
Show answer
Answer C: Stay stopped until you can see that the turn is safe
Turning right on red is permitted, never required, so you wait until you can see that the way is clear no matter what the driver behind does.
-
3. A yellow diamond showing two vertical arrows, one pointing up and one pointing down, warns that
Show answer
Answer A: the road ahead carries traffic in both directions
The two-way traffic sign warns that the roadway ahead is not divided and that vehicles will be coming from the opposite direction.
-
4. How current must an Idaho verification of school compliance document be when it is presented?

ITD requires the verification of compliance to be presented within one year of the date listed on the document.
-
5. What is worth carrying in the vehicle during a winter trip?
Show answer
Answer A: A blanket, a flashlight, a scraper and a small shovel
A winter kit keeps you warm and visible if you are stopped for hours, and lets you clear glass and dig the wheels out. Hot water can crack cold glass.
-
6. During the pre-drive vehicle knowledge check for the Idaho skills test, how many items may an applicant fail to locate or demonstrate and still continue?
Show answer
Answer A: Three or fewer
The applicant must locate or demonstrate items such as the horn, wipers, signals and the three arm signals, and missing three or fewer allows the test to continue.
-
7. A yellow diamond showing the silhouette of a deer warns that
Show answer
Answer D: large animals may cross the road in that area
The sign marks a stretch where animals are known to cross, so drivers should reduce speed and scan both roadsides, especially around dawn and dusk.
-
8. You are joining a highway from a short ramp that has no acceleration lane. What should you do?
Show answer
Answer A: Stop or slow at the end of the ramp and wait for a safe gap
Without an acceleration lane there is no room to match speed, so you must yield at the end of the ramp and enter only when a gap allows it.
-
9. Under Idaho's GDL penalties, what happens to a driver under 17 on a second conviction for a moving traffic violation?
Show answer
Answer B: A 30-day suspension of driving privileges
Idaho issues a warning letter for a first moving violation conviction, a 30-day suspension for a second, and a 60-day suspension for a third or later conviction.
-
10. A yield sign is posted where an entrance ramp meets the highway. What must you do?
Show answer
Answer C: Give way to the traffic already on the highway and merge into a gap
The yield sign confirms that the merging driver is the one who must fit into the traffic stream rather than the other way round.
-
11. A sign warns that your exit leaves from the left side of the freeway. What should you do?
Show answer
Answer D: Move into the left lane in good time before you reach the exit
Left-hand exits are unusual, which is exactly why they are signed well in advance and why the lane changes should be finished early.
-
12. Your loaded vehicle weighs more than the figure shown on a posted weight limit sign. What must you do?
Show answer
Answer D: Find another route, because crossing is not permitted
A posted weight limit is a legal maximum, not advice, so an overweight vehicle has to take a different route.
-
13. You are driving forward into a perpendicular space with a large pickup parked on the right of it. How should you take it?
Show answer
Answer D: Stay wide, turn in late and keep clear of the pickup
Starting the turn later keeps the rear of your car away from the vehicle beside the space, which is exactly what a tight early turn clips.
-
14. On a narrow residential street, why does parking tight against the curb matter so much?
Show answer
Answer C: Because fire trucks and ambulances need the width to get through
Cars parked even a foot out from the curb on both sides can narrow a street until a fire truck or ambulance cannot pass.
-
15. You are about to slow down sharply for a turn. Which check comes first?
Show answer
Answer A: A look in the mirror to see how close the traffic behind you is
Any hard slowing needs a mirror check first, because the driver behind is the one who has to react to it.
-
16. You are stopped at a stop sign on a two-way stop intersection and the cross street has no stop signs at all. What does that mean for you?
Show answer
Answer A: You yield to all cross traffic no matter how long that takes
At a two-way stop only your direction is controlled, so there is no taking turns; you wait for a gap big enough to enter safely.
-
17. You have signaled and pulled up level with the car in front of an empty curb space. What comes next?
Show answer
Answer A: Reverse slowly while turning the wheel toward the curb
From alongside the forward car you back in on a turn toward the curb, then straighten and swing the front in as the rear reaches the space.
-
18. Where is this sign installed in relation to the hazard it announces?
Show answer
Answer A: Far enough before the hazard that a driver can slow down and stop short of it
This is an advance warning sign, placed on the approach so a driver has time to react before reaching a crossing that a curve or a crest may be hiding.
-
19. An overhead lane signal shows a flashing yellow X above your lane. What does it mean?
Show answer
Answer D: The lane may be used only for a left turn
A flashing yellow X marks a lane that may be used only to make a left turn; a steady yellow X is the one that warns you to leave the lane.
-
20. Two solid white lines separate your lane from the lane beside it. What do they mean?
Show answer
Answer B: Crossing from one lane to the other is prohibited
A solid double white line marks a boundary that road users may not cross, such as the entrance to a preferential lane.
-
21. A yellow diamond shows a car with wavy lines behind its rear tires. What is the warning?
Show answer
Answer D: The surface loses grip badly when it is wet
The slippery when wet sign marks a stretch where traction falls off sharply in rain, so speed and braking must be reduced well in advance.
-
22. Your vehicle leaves the road and enters deep water. What gives you the best chance of escape?
Show answer
Answer B: Release your seat belt and get out through a window as quickly as possible
Water pressure holds the doors shut, so a window is the reliable exit and the first seconds after entry are the best time to use it.
-
23. Where are signs of this kind placed at an intersection?
Show answer
Answer C: At the near right and far left corners, facing drivers on the intersecting street
They are installed at the corners of the intersecting street so that a driver about to turn in sees the restriction before committing to the turn.
-
24. Your power steering fails while you are driving. What happens and what should you do?
Show answer
Answer B: Steering becomes much harder but still works, so slow down and pull off the road
Without power assistance the steering still works, but it takes much more effort, especially at low speed. Keep both hands on the wheel and get off the road.
-
25. Federal law lets a state open its high-occupancy vehicle lanes to certain vehicles carrying only one person. Which of these is covered by that allowance?
Show answer
Answer B: Motorcycles
Federal law lets states allow motorcycles into high-occupancy vehicle lanes regardless of the number of occupants, because keeping riders in the flow is safer than the alternative.
-
26. Why does the speed of the right-hand lane of a freeway change so often?
Show answer
Answer B: Vehicles entering and leaving the highway all use that lane
Entrance and exit ramps feed into the right lane, so traffic there is constantly slowing to leave or speeding up to join.
-
27. Besides motorist services and tourist information, a blue sign background is also used for
Show answer
Answer B: evacuation route signing
Blue is assigned to road user services, tourist information and evacuation routes, so hurricane and other evacuation routes are signed in blue.
-
28. An overhead sign shows that the right lane is EXIT ONLY. What does that mean if you intend to stay on the highway?
Show answer
Answer B: You have to move out of that lane before the exit
An exit only lane leaves the highway completely, so a driver continuing on the highway has to change lanes before it does.
-
29. What belongs in a basic emergency kit carried in a car?
Show answer
Answer D: A flashlight, a first aid kit, jumper cables and some warning devices
A useful kit lets you see, be seen, treat an injury and restart the vehicle; carrying loose gasoline is a fire risk.
-
30. Your parking brake no longer holds the car on a slope. What should you do?
Show answer
Answer D: Have it repaired, and until then park only on level ground
A parking brake that will not hold is a defect to be fixed; avoiding grades in the meantime keeps the vehicle from rolling away.
-
31. A row of solid white triangles points toward you across your lane. What does it mark?
Show answer
Answer A: The place to yield to traffic or people ahead
A yield line of triangles shows drivers exactly where to give way, and it is used at roundabouts and at midblock crosswalks.
-
32. Another driver has pulled out to pass you. What should you do?
Show answer
Answer A: Stay in your lane, keep your speed steady or ease off, and let the pass finish
Accelerating while being passed forces the other driver to stay in the opposing lane longer, so the safe response is to hold or slightly reduce speed and stay right.
-
33. In Idaho, what must you do when approaching a stopped emergency vehicle, tow truck or incident response vehicle with lights flashing?
Show answer
Answer D: Reduce speed below the posted limit and, on a road with two or more lanes in your direction, move out of the adjacent lane when safe
Idaho law requires drivers to immediately reduce speed below the posted limit and, where there are two or more lanes in the same direction, to change into a lane that is not adjacent to the stopped vehicle when it is safe.
-
34. Your phone is in a mount on the dashboard rather than in your hand. What is true?
Show answer
Answer B: It still takes your eyes and mind off the road
A mount solves the hand problem but not the eye or the mind problem, and reading or tapping a mounted screen costs the same seconds of attention.
-
35. What happens when tires are driven underinflated for a long time?
Show answer
Answer D: They wear at the edges, they run hot and they are more likely to fail
An underinflated tire flexes too much, which wears the shoulders and builds up heat that can destroy the tire.
-
36. Which of these is true of the roadway a driver is being sent onto here?
Show answer
Answer D: Its own signs, signals and speed limits govern for the whole way around
The alternate route is an ordinary public road, so every control posted on it governs as usual; being sent that way grants no extra priority and no relief from the limits in force there.
-
37. A driver's destination lies along the street to the right, and this sign stands at that corner. How should the driver reach it?
Show answer
Answer D: By going on and using a later intersection where turning is allowed
When a movement is barred at one corner the driver has to reroute, normally by continuing and coming back to the destination from a permitted approach.
-
38. You are driving in the left lane at the posted speed limit and a line of vehicles has built up behind you. What should you do?
Show answer
Answer D: Move into a lane on your right when it is safe and let the traffic behind go by
Most states require traffic moving slower than the flow to keep right and reserve the left lane for passing, so a driver holding up a line of vehicles should move right when it is safe rather than block the lane.
-
39. A yellow pennant-shaped sign is posted on the left side of a two-lane road facing you. What is it telling you?
Show answer
Answer B: You are entering a no-passing zone and may not start a pass
The pennant is placed on the left so that it faces the driver who might pull out, and it marks the beginning of a no-passing zone.
-
40. During which period may studded snow tires normally be used in Idaho?
Show answer
Answer C: October 1 through April 30
Idaho allows studded snow tires from October 1 to April 30, and the Transportation Department may adjust the dates in some years because of weather.
