1. When may an Idaho Class D skills test be scheduled?
Show answer
Answer C: Only during daylight hours and in acceptable weather conditions
Idaho restricts Class D skills tests to daylight hours and acceptable weather, and a test may be rescheduled when conditions do not meet that standard.
-
2. Why would a restriction like this one be applied to a stretch of road?
Show answer
Answer A: Because there is not enough visible road ahead to complete a pass safely
Limits on overtaking are set where a hill, a curve or an obstruction leaves too little sight distance for a driver to pull out, pass and return before meeting oncoming traffic.
-
3. What does Idaho require of the insurer that covers a registered vehicle?
Show answer
Answer B: It must be licensed to do business in Idaho
Idaho requires vehicles to be insured with an insurance company licensed to do business in the state, and coverage is then verified electronically.
-
4. Where should the lap part of the seat belt sit?
Show answer
Answer C: Low and snug across the hips, touching the tops of both of the thighs
The hip bones can take crash forces, but the abdomen cannot, so the lap belt goes low and tight across the hips.
-
5. The overhead signal above your lane changes to a steady yellow X. What should you do?
Show answer
Answer B: Prepare to move out of that lane
A steady yellow X warns that the lane is about to close, so drivers should get ready to vacate it in favor of an open lane.
-
6. A driver who wants to reverse direction arrives at this sign. What is allowed?
Show answer
Answer C: Going on and reversing direction only where the maneuver is permitted
The restriction removes that maneuver at that spot entirely, so the driver has to continue and turn the vehicle around at a place where it is not prohibited.
-
7. What does a blood alcohol concentration of 0.08 mean for the driver of a car?
Show answer
Answer B: It is the level almost every state treats as legally intoxicated
In almost every state a driver at 0.08 or above is legally intoxicated whatever the driver seems like, but impairment starts well before that level is reached.
-
8. The engine dies at speed and the dashboard lights go out on a dark road. What should you do?
Show answer
Answer C: Hold the wheel firmly, steer over to the shoulder and use the hazard lights
Never switch the ignition to lock, because the steering can lock; steer to the shoulder and warn traffic with the hazard lights.
-
9. Smoke and flames appear from the engine compartment after you stop. What should you do?
Show answer
Answer A: Get everyone well away from the vehicle first, and then call the fire service
A vehicle fire can spread within seconds, so people come out first and firefighting is left to the fire service.
-
10. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
-
11. Which of these is an early warning that you are too tired to keep driving?
Show answer
Answer C: Not remembering the last few miles you drove
Memory gaps, repeated yawning, heavy eyelids and drifting are the body signaling that sleep is winning, and they mean stop rather than push on.
-
12. A sign with a black legend on a fluorescent pink background is used for
Show answer
Answer A: traffic incident management
Fluorescent pink is set aside for signing that manages traffic around a crash, a spill or another unplanned incident, so it stands apart from routine work zone orange.
-
13. A steady red arrow is displayed for your left-turn lane at a two-way intersection. What must you do?
Show answer
Answer C: Stop and remain stopped until an indication permits the turn
A steady red arrow prohibits the movement it points to, so the driver stops and waits for a green arrow, a flashing yellow arrow or another indication that permits the turn.
-
14. A tractor-trailer is backing slowly across the roadway to enter a loading dock. What should you do?
Show answer
Answer C: Stop and wait until the truck has finished the maneuver
A backing truck driver has a very limited view and the trailer can swing unexpectedly. Trying to squeeze past in either direction risks being crushed.
-
15. A driver is following you far too closely and you have a turn coming up. How should you slow down for it?
Show answer
Answer B: Signal early and slow gradually well before the turn
Early signals and gentle braking give a tailgater the time and distance they have failed to leave for themselves.
-
16. Why do many crashes happen on routes the driver knows very well?
Show answer
Answer D: Familiar roads let attention slip into routine
When a route is automatic the mind wanders and hazards get missed, which is why a well known road deserves the same attention as a strange one.
-
17. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
18. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
19. A yellow sign shows a truck on a slope with the legend 7 PERCENT GRADE. What should a driver of a heavy vehicle do?
Show answer
Answer A: Select a lower gear before starting down
The percentage shows how steep the descent is, and choosing a low gear at the top lets the engine hold the vehicle back instead of the brakes overheating.
-
20. You are waiting to enter a two-lane roundabout and traffic is circulating in both lanes. What must you do?
Show answer
Answer A: Yield to traffic in both circulating lanes before you enter
Every entry to a roundabout is a yield point, and at a two-lane roundabout that means giving way to vehicles in either circulating lane.
-
21. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
22. How should speed and following distance be adjusted beyond this sign?
Show answer
Answer D: Cut speed and leave a longer gap, because traffic can stop without warning
Traffic in these areas stops and starts unexpectedly and there is little room to steer around a problem, so extra space is what prevents a rear-end collision.
-
23. You have turned onto a street and see parked cars facing you and headlights coming toward you. What has probably happened?
Show answer
Answer C: You have turned the wrong way onto a one-way street
Vehicles parked facing you and headlights approaching in your lane are the classic signs of driving against the flow on a one-way street.
-
24. A sign with a yellow background and a black legend generally conveys
Show answer
Answer B: a general warning
Yellow is the background color used for general warning signs, so a yellow sign tells the driver to expect something ahead rather than to obey a rule.
-
25. You are on an entrance ramp merging onto a freeway. Who has to give way?
Show answer
Answer B: You must yield and fit into a gap in the traffic already on the freeway
Traffic entering a highway must yield to traffic already on it. Use the acceleration lane to match speed and merge into a gap.
-
26. On a two-lane road with a broken yellow center line, may you cross it to turn into a driveway on the left?
Show answer
Answer C: Yes, when it is safe and the oncoming lane is clear
A broken center line may be crossed for a pass or for a left turn into a road or a driveway, once the oncoming lane is clear.
-
27. An emergency vehicle approaches with its siren sounding and lights flashing. What does Idaho law require?
Show answer
Answer A: Pull to the nearest curb or right edge, clear of any intersection, and stop
Idaho requires drivers to pull immediately to the nearest curb or the right edge of the roadway, clear of any intersection, and remain stopped until the emergency vehicle has passed.
-
28. A bicyclist stops at a four-way stop just before you do. Who goes first?
Show answer
Answer B: The bicyclist, who reached the intersection and stopped there before you did
A bicyclist on the roadway follows the same right of way rules as a driver, so arrival order decides the turn.
-
29. An emergency vehicle is stopped on the shoulder ahead with its lights flashing. What does the move over principle require?
Show answer
Answer D: Change lanes away from it, or slow down if you cannot
Move over laws ask you to give responders an empty lane, and where traffic or a two-lane road makes that impossible, you slow down instead.
-
30. What does Idaho attach to violations of school zone speed limits?
Show answer
Answer C: Increased penalties
The Idaho handbook warns that there are increased penalties for violating school zone speed limits.
-
31. Some drivers believe they can multitask while driving. What does research show?
Show answer
Answer C: The brain switches rapidly between tasks and driving performance suffers
The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.
-
32. Unless otherwise posted, what is the maximum speed on Idaho state highways?
Show answer
Answer B: 65 miles per hour, with 70 allowed where posted
Idaho caps state highways at 65 miles per hour unless otherwise posted, and 70 may be allowed where it is specifically posted.
-
33. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
34. How do strong emotions affect driving?
Show answer
Answer B: They narrow your attention and make risky decisions more likely
Anger, worry and excitement all take attention away from the driving task and push drivers toward decisions they would not normally make.
-
35. An exit ramp is separated from the highway by a triangle of pavement painted with white stripes. What may you do there?
Show answer
Answer C: Nothing; keep off it and choose either the lane or the ramp
The striped area between a ramp and the through lanes is not for driving, stopping or last-second changes of direction.
-
36. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
37. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
38. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?
Show answer
Answer B: It sets a lower legal limit for trucks
A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.
-
39. A school sign paired with a plaque showing a diagonal downward-pointing arrow is installed
Show answer
Answer D: at the school crossing itself, or as close to it as possible
The diagonal downward arrow points at the crossing, so this assembly is placed at the crossing location rather than in advance of it.
-
40. You are driving on the through road of a T-intersection and want to turn left into the side road. Oncoming traffic is approaching on the through road. What must you do?
Show answer
Answer C: Yield to the oncoming traffic before you turn
The vehicle waiting in the stem of the T yields to both of you, but you still owe the right of way to oncoming through traffic before turning across it.
