1. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.
-
2. Which family of signs normally uses a rectangle that is wider than it is tall?
Show answer
Answer B: Guide signs, which name routes and destinations
Guide signs are laid out as horizontal rectangles because they have to carry route numbers, place names and distances side by side.
-
3. A steady downward green arrow is displayed over a lane. What does it indicate?
Show answer
Answer C: The lane is open to traffic in your direction
A steady downward green arrow means the lane it points to is open to traffic traveling in your direction.
-
4. How does a lap and shoulder belt protect you in a crash?
Show answer
Answer B: It holds you to the seat and spreads the force over the strong bones
The belt keeps you with the vehicle as it slows and puts the load on the hips and the chest rather than on soft tissue.
-
5. What does a booster seat do for a child?
Show answer
Answer B: It lifts the child so that the adult belt crosses hips and shoulder
A booster raises the child so the adult belt lies on the strong parts of the body instead of the neck and the abdomen.
-
6. A driver's blood alcohol concentration is below the legal limit, but the driver is visibly impaired. Can the driver be arrested?
Show answer
Answer C: Yes, driving while impaired by alcohol is an offense at any concentration
The per se figure, 0.08 percent in most states and 0.05 percent in Utah, is the level at which impairment is presumed. Impairment shown by driving behavior and field tests is enough on its own, because alcohol affects skills well before that number.
-
7. On a regulatory sign, what does a red circle with a diagonal slash drawn over a symbol mean?
Show answer
Answer D: The movement or action shown by the symbol is prohibited
A red circle with a diagonal slash is the standard way of showing that the movement pictured inside it, such as a U-turn or a right turn, is not allowed.
-
8. A sign reads MINIMUM SPEED 40. What does it require of a driver?
Show answer
Answer C: Not to drive below that speed when conditions allow
A minimum speed limit keeps unnecessarily slow vehicles from obstructing traffic, but it never overrides the duty to slow down for weather or congestion.
-
9. How should the outside mirrors be aimed to reduce your blind spots?
Show answer
Answer A: Outward, so each one covers the lane beside you rather than repeating the inside mirror
Mirrors aimed too far inward show you the same road three times and leave a large gap beside the vehicle, so aiming them outward shrinks the blind spot.
-
10. You will leave your vehicle for several hours after dark. Where is the best place to park it?
Show answer
Answer D: In a well-lit spot with people and cameras nearby
Light, passing people and cameras all discourage theft and make your own return to the vehicle safer.
-
11. Is it acceptable to watch a video on a screen positioned where you can see it while driving?
Show answer
Answer B: No, the screen pulls your eyes and attention away from the road
Moving pictures are among the strongest visual distractions. Video screens must be out of the driver's view while the vehicle is moving.
-
12. Your right wheels have dropped onto a soft shoulder. Why should you not steer straight back onto the pavement?
Show answer
Answer A: The tires can catch the pavement edge and throw you across the road
A tire pressed against the edge of the pavement climbs it suddenly, and at speed that jolt can send the vehicle across the center line.
-
13. Your engine stalls while you are driving in traffic. What is the correct response?
Show answer
Answer A: Shift to neutral, try to restart it, and steer and brake toward the side of the road
With the engine off, power steering and power brake assistance fade, so steering and braking take more effort but still work. Neutral lets you attempt a restart while you coast to safety.
-
14. You have stopped on the shoulder of a busy freeway with a flat tire that you cannot change safely. Where should you and your passengers wait?
Show answer
Answer A: Well away from the traffic side, behind a barrier or up the bank if there is one
People struck on the shoulder are a common cause of roadside deaths, so wait away from the traffic side and behind any barrier.
-
15. A small yellow plaque showing a speed number below a curve warning sign gives
Show answer
Answer C: the speed recommended for the condition being warned about
The advisory speed plaque belongs to the warning series and states the speed judged safe for the condition ahead under good circumstances, not a regulatory limit.
-
16. A pedestrian steps off the curb in the middle of a block where there is no crosswalk at all. What is the legal position?
Show answer
Answer A: They must yield to you, but you must still avoid a crash
A pedestrian crossing away from a crosswalk yields to vehicles, yet every driver still has a duty to use care and avoid hitting a person.
-
17. How should you position your vehicle for a right turn from a two-way street?
Show answer
Answer B: As close as practical to the right curb or edge, then turn into the nearest right lane
Right turns are made from the lane nearest the right edge into the nearest available lane, which keeps the turn tight and prevents a wide sweep into other traffic.
-
18. How much moving water is generally enough to float and carry away most passenger vehicles?
Show answer
Answer D: About one foot
About a foot of moving water will float most cars, and even less will stall an engine. That is why the rule is to turn around instead of judging the depth.
-
19. A sign showing a walking figure carries a plaque below it with an arrow slanting down to the right. What does the plaque add?
Show answer
Answer B: The crossing is at that very spot
A downward-slanting arrow plaque marks the crossing itself, whereas an AHEAD or distance plaque would place it further along the road.
-
20. A sign warns that the right lane ends ahead, and traffic is still flowing freely. What should you do if you are in that lane?
Show answer
Answer C: Signal, adjust your speed and move left in good time before the lane ends
When traffic is moving freely there is room to merge early and smoothly, which avoids the last-second lane change at the closure point.
-
21. You have parked a manual transmission car facing downhill. Which gear should you leave it in?
Show answer
Answer D: Reverse, along with the parking brake set firmly
Facing downhill the car would roll forward, so reverse gear opposes that movement while the parking brake and turned wheels back it up.
-
22. School warning signs use which background and legend colors?
Show answer
Answer A: A black legend and border on a fluorescent yellow-green background
School warning signs carry a black legend and border on a fluorescent yellow-green background, a shade chosen so they stand out from ordinary yellow warning signs.
-
23. The brake warning light stays on even though the parking brake is fully released. What does it indicate?
Show answer
Answer B: A possible brake system problem, so have the brakes checked promptly
The brake warning light also signals low brake fluid or a failure in one part of the hydraulic system. Do not ignore it, because braking may be reduced.
-
24. How long can cannabis affect a driver?
Show answer
Answer A: For hours after the strongest effects have passed
Slowed reactions, poor tracking and weak judgment of distance can last for hours, well beyond the point where the user believes the effects are over.
-
25. In a vehicle with automatic transmission, which foot should operate the brake and accelerator?
Show answer
Answer D: The right foot for both pedals
Using only the right foot prevents pressing both pedals at once and keeps the response the same in every vehicle you drive. The left foot rests on the floor or the footrest.
-
26. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
27. What makes up the total distance needed to bring a vehicle to a stop?
Show answer
Answer A: The distance covered while you perceive the hazard, the distance covered while you react, and the braking distance
Total stopping distance combines the ground covered while you notice the hazard, the ground covered while you move your foot to the brake, and the ground covered while the brakes slow the vehicle.
-
28. You are stopped at a stop sign waiting to turn onto a highway where traffic moves at 55 mph. How should you choose your gap?
Show answer
Answer A: Wait for a much larger gap than the one you would accept on a city street
Fast traffic covers ground while you are still accelerating, so the gap that feels adequate at 25 mph is dangerously short at highway speed.
-
29. You approach an intersection where the signal is flashing yellow. What should you do?
Show answer
Answer D: Slow down and cross the intersection with caution
A flashing yellow signal warns you to slow down and cross with care; it does not require a stop, but it does not give you priority either.
-
30. Idaho's child restraint law applies to children of what age in a non-commercial motor vehicle?
Show answer
Answer D: Six years of age or younger
Idaho law requires anyone carrying children six years of age or younger in a non-commercial vehicle to secure them in an approved child safety seat.
-
31. Where must an open container of alcohol be carried in an Idaho vehicle?
Show answer
Answer C: In the trunk, or behind the last upright seat if the vehicle has no trunk
Idaho's open container law requires unsealed alcoholic beverages to travel in the trunk, or behind the last upright seat when the vehicle has no trunk.
-
32. Why does the situation ahead of this sign deserve extra care from a motorcyclist?
Show answer
Answer C: Because a narrow machine is easy to overlook in a mirror or a blind spot
A motorcycle fills very little of a mirror and disappears easily into a blind spot, so the rider should adjust speed and lane position to stay visible where the streams come together.
-
33. You are traveling beside another vehicle on a multilane highway at nearly the same speed. Why is this a poor position?
Show answer
Answer B: You may be sitting in that driver's blind spot with nowhere to go if they move over
Driving alongside removes your side escape route and often puts you where the other driver cannot see you. Speed up or drop back to open space beside you.
-
34. About how far does a vehicle travel in one second at 60 mph?
Show answer
Answer A: About 88 feet
At 60 mph you cover about 88 feet every second, which is why a glance of only two or three seconds means driving the length of several vehicles blind.
-
35. How long is the mandatory license suspension for a first DUI conviction when the Idaho driver is under 21?
Show answer
Answer A: One year
Idaho lengthens the first-conviction suspension to one year when the driver is under 21, compared with 90 to 180 days for drivers 21 and older.
-
36. A turn restriction sign at the corner shows a range of times below the symbol. What does that mean?
Show answer
Answer A: The turn is banned only during the hours shown on the sign
Times posted under a regulatory symbol set the period during which the restriction applies; outside those hours the movement is permitted.
-
37. What should a driver expect a short distance beyond this sign?
Show answer
Answer C: Another road crossing the one being traveled
Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.
-
38. On a two-lane road, a solid yellow line runs on your side of the center while a broken yellow line runs on the other side. What does this mean?
Show answer
Answer D: You may not pass, although oncoming drivers may
Passing restrictions are read from the line closest to your own lane, so a solid yellow line on your side creates a no-passing zone for you alone.
-
39. When is passing another vehicle on the right generally permitted?
Show answer
Answer C: When the road has two or more lanes in your direction, or the vehicle ahead is turning left and there is room without leaving the pavement
Passing on the right is limited to situations where a lawful lane exists for it or the vehicle ahead is turning left, and it may never be done by driving onto the shoulder.
-
40. Is it acceptable to drive with your vehicle straddling the line between two lanes?
Show answer
Answer D: No, you must drive as nearly as practical entirely within a single lane
A vehicle astride the line takes up two lanes and leaves the drivers around it unable to predict where it will go.
