2. How long should a young child ride in a rear-facing child seat?
Show answer
Answer D: Until the child outgrows the height or the weight limit of the seat
Rear facing is the safest position and should be kept until the child reaches the top height or weight allowed by the seat.
-
3. What is the safest way to deal with the situation this sign announces?
Show answer
Answer B: Match the speed of the other traffic stream and open a gap so vehicles can blend without hard braking
Blending works when speeds are matched and gaps are opened, so nobody has to brake hard or swerve where the two streams come together.
-
4. A bicycle symbol topped by two chevrons is painted in the middle of a travel lane. What does that marking indicate?
Show answer
Answer D: Bicyclists share the lane with motor vehicles and may ride away from the curb
A shared lane marking shows drivers where bicyclists are likely to ride in a lane used by both bicycles and motor vehicles.
-
5. You must leave your vehicle beside a narrow rural road at night. What should you do?
Show answer
Answer B: Get it right off the pavement and switch on the hazard lights
A vehicle left on an unlit rural road is very hard to see, so move it completely clear of the traveled surface and mark it with the hazard lights.
-
6. You are traveling at 55 mph on a rural road and come up behind a horse-drawn buggy. What is the main danger?
Show answer
Answer D: You close on it very quickly because it moves at walking pace
A buggy travels only a few miles an hour, so the gap closes far faster than drivers expect and there is very little time to brake once you see it.
-
7. What is a microsleep?
Show answer
Answer D: A few seconds of sleep, sometimes with the eyes open
A microsleep is an involuntary lapse of a few seconds during which the driver is asleep and the vehicle travels blind, often without the driver knowing.
-
8. When may an Idaho driver pass a funeral procession in the right lane of a multi-lane highway?
Show answer
Answer D: Only when the procession itself is occupying the farthest left lane
Idaho forbids passing a funeral procession in the right lane of a multi-lane highway unless the procession is in the farthest left lane.
-
9. You arrive at an intersection where the traffic signal is completely dark because of a power failure. How should you proceed?
Show answer
Answer C: Treat the intersection as an all-way stop
When a signal shows no indication at all, drivers on every approach must stop and then take turns, exactly as at an all-way stop.
-
10. When should you enter a destination into a navigation device?
Show answer
Answer B: Before you start driving, or after parking in a safe place
Programming a route is a visual, manual and mental task at the same time, so it belongs to the moments before the vehicle moves rather than to any point in traffic.
-
11. Why is a wet road at night harder to read than the same road in daylight?
Show answer
Answer A: The wet surface reflects light away and swallows the lane markings
A film of water sends your headlight beam onward instead of back to you, so lines, edges and people in dark clothing almost disappear.
-
12. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
13. In a work zone the temporary lane lines conflict with the old lines still visible on the pavement. Which do you follow?
Show answer
Answer C: The temporary markings, which show the current traffic pattern
Temporary markings define the traffic pattern in force, and the old lines are simply the layout that no longer applies.
-
14. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
15. What does Idaho ask of drivers who meet an oncoming pilot vehicle escorting an oversized load?
Show answer
Answer C: Reduce speed and position your vehicle as far to the right as possible
When meeting an oncoming pilot vehicle with amber warning lights, Idaho drivers should reduce speed and position themselves as far to the right as possible.
-
16. You are about to leave a roundabout when a pedestrian steps into the crosswalk on your exit. What should you do?
Show answer
Answer B: Yield to the pedestrian and wait for the crosswalk to clear
Roundabout crosswalks sit on the entries and exits, and drivers must yield to pedestrians using them.
-
17. A streetcar is coming along tracks in the middle of the street as you wait to turn across them. What should you do?
Show answer
Answer A: Let the streetcar pass before you cross the tracks
Rail vehicles cannot steer around you and need a long distance to stop, so drivers yield to a streetcar or light rail train.
-
18. What fee must an Idaho vehicle owner pay to reinstate a registration suspended for lack of insurance?
Show answer
Answer A: $75
Idaho charges a $75 reinstatement fee, along with proof of insurance, to restore a registration suspended under the Drive Insured program.
-
19. How many points in any 24-month period bring a 90-day suspension in Idaho?
Show answer
Answer B: 18 to 23 points
Idaho imposes a 90-day suspension for 18 to 23 points accumulated in any 24 months, one step above the band that carries a 30-day suspension.
-
20. On the Interstate system, what do the odd-numbered one and two digit routes have in common?
Show answer
Answer D: They run mainly north and south
Odd numbers are given to north and south Interstates and even numbers to east and west ones, with the numbers rising toward the north and the east.
-
21. What do two solid yellow lines down the middle of a two-way road mean?
Show answer
Answer D: Passing is prohibited for traffic in both directions
A double solid yellow line marks a two-direction no-passing zone, so neither direction may cross it to overtake another vehicle.
-
22. A pedestrian with a white cane draws the cane back and steps away from the curb as you approach. What does that usually mean?
Show answer
Answer B: They are signaling you to go ahead and drive on
Pulling the cane in and stepping back from the curb is the customary way a blind pedestrian tells drivers to proceed.
-
23. How is the yield sign shaped and colored?
Show answer
Answer C: A downward-pointing triangle with a wide red border and a red legend on white
The yield sign is a downward-pointing equilateral triangle with a wide red border and the legend in red on a white background, an outline used for no other message.
-
24. Idaho allows a passing speed exception on two-lane roads. What does it permit?
Show answer
Answer C: Exceeding the posted limit by up to 15 mph while passing where the limit is 55 mph or greater, outside work zones
A passenger vehicle, pickup or motorcycle that is not towing may exceed the posted limit by up to 15 mph while passing a slower vehicle on a two-lane road posted at 55 mph or more, but never in a work zone.
-
25. What can a loose or doubled up floor mat on the driver side cause?
Show answer
Answer A: It can slide forward and trap the accelerator pedal down
An unsecured mat, or a second mat laid over the first, can slip forward and hold the accelerator open. Use the mat clips and never stack mats.
-
26. The road ahead is broken up with potholes and rough patches. What should you do?
Show answer
Answer C: Slow down, since a hole hit at speed can wreck a tire or wheel
A lower speed cuts the impact on tires, wheels and suspension and gives you time to choose a line through the rough surface.
-
27. An Idaho load extends five feet beyond the rear of the vehicle. What must be displayed at the end of it during the day?
Show answer
Answer C: A red flag at least 18 inches square
When a load extends four feet or more beyond the rear of a vehicle, Idaho requires a red flag at least 18 inches square by day and a red light visible for at least 500 feet at night.
-
28. After turning right you see a sign showing that your lane ends a short way ahead. What should you do?
Show answer
Answer B: Signal and merge into the next lane while there is still room
Merge early and smoothly while a gap is still available, rather than running out of pavement or forcing your way in at the last moment.
-
29. Where is a U-turn most clearly unsafe and generally prohibited?
Show answer
Answer D: On a curve or near a hill crest, where other drivers cannot see you
U-turns are barred where approaching drivers cannot see you in time, such as on a curve or near the top of a hill.
-
30. The center line beside your lane is a broken yellow line. What does it allow?
Show answer
Answer D: You may cross into the opposing lane to pass when it is safe and clear
A broken yellow center line marks a passing zone where traffic in that direction may cross into the opposing lane to pass when the way ahead is clear.
-
31. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
32. A driver leaves the vehicle at the curb where this sign is posted and walks away for two minutes. Is that allowed?
Show answer
Answer B: No, leaving the vehicle unattended there is prohibited whatever the length of the absence
Walking away leaves the vehicle parked, and the prohibition holds regardless of how long the driver is gone or whether the engine is left running.
-
33. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
34. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
-
35. How much clear road do driver manuals say you need before starting a pass at highway speed on a two-lane road?
Show answer
Answer C: Enough to complete the pass and return, roughly ten to twelve seconds of travel
At highway speed the whole maneuver of pulling out, overtaking and returning takes roughly ten to twelve seconds, and every foot of that has to be visible before you start.
-
36. What should you do before leaving a parked vehicle unattended?
Show answer
Answer C: Set the parking brake, place the transmission in park or in gear, switch off the engine and take the key
Securing the vehicle with the parking brake, the transmission and the ignition prevents it from rolling away and from being moved by someone else.
-
37. Once a driver has joined the route this sign begins, how is the rest of the way marked?
Show answer
Answer B: By further markers of the same kind at each turn, until the original road is rejoined
The alternate route is signed continuously, with a marker at every turn, so a driver with no local knowledge can follow it back to the original road.
-
38. About how far ahead do low beam headlights let you see on a dark road?
Show answer
Answer B: About 250 feet
Low beams light roughly 250 feet of road, and high beams roughly 350 to 500 feet, which sets the limit on a safe night speed.
-
39. Trees block the view along the tracks as a driver approaches this sign. What approach speed is correct?
Show answer
Answer B: Slow enough to stop before the nearest rail once a train comes into view
Where the view along the track is obstructed, the only safe speed is one that still leaves stopping distance after a train first becomes visible.
-
40. You cannot avoid a wide puddle that covers only the right half of your lane. What should you expect?
Show answer
Answer D: The water can tug the vehicle toward that side, so slow before it and grip the wheel
Water dragging on the tires of one side only pulls the vehicle that way. Reduce speed before you reach it and hold the wheel firmly.
