1. The sun is low behind you and shining into the eyes of oncoming drivers. What should you do?
Show answer
Answer C: Turn on your headlights and expect oncoming drivers not to see you
Drivers facing the low sun may not see you at all, so make yourself as visible as possible and give way rather than insisting on your right of way.
-
2. Why is a sign reading BRIDGE ICES BEFORE ROAD worth heeding even when the road itself is merely wet?
Show answer
Answer C: Cold air passes under a bridge as well as over it
A bridge deck loses heat from below as well as above, so it can be frozen while the road on either side of it is only wet.
-
3. 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.
-
4. Two drivers each have three drinks, one over three hours and one in half an hour. What is the difference?
Show answer
Answer C: The fast drinker reaches a higher peak level
The liver removes alcohol at a steady rate, so drinking faster than the body can clear it pushes the blood alcohol level much higher.
-
5. A sign on a long downgrade points to a runaway vehicle ramp. What is that ramp for?
Show answer
Answer C: Trucks that have lost braking ability on the grade
A runaway ramp is an escape lane of loose material that stops a heavy vehicle whose brakes have overheated or failed, so it must always be left clear.
-
6. What blood alcohol concentration makes a driver under 21 guilty of driving under the influence in Idaho?
Show answer
Answer C: .02 or more
Idaho law sets the driving under the influence threshold at .02 or more for drivers under 21, well below the .08 that applies to drivers 21 and older.
-
7. What does a broken line indicate, whatever color it is painted?
Show answer
Answer C: That crossing it is permitted
A broken line always describes a permissive condition, and the color then tells the driver whether the traffic beyond it runs the same way or the opposite way.
-
8. 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.
-
9. While you swerve around an obstacle, what should the rest of your body be doing?
Show answer
Answer C: Staying upright with the knees against the tank while the motorcycle leans
A swerve happens through the handlebars, and a body that stays still and anchored to the tank lets the motorcycle move quickly beneath the rider.
-
10. What does Idaho require of a motorcycle rider with respect to liability insurance?
Show answer
Answer D: Coverage must be held, and proof of it must be carried on the motorcycle
Idaho lists liability insurance among the requirements for motorcycles ridden on the highway, and the rider must both hold the coverage and carry proof of it.
-
11. An Idaho traffic signal will not detect your motorcycle. What does Idaho law allow?
Show answer
Answer C: After a complete stop and one full signal cycle, proceed with caution through the red light while yielding to all traffic
Idaho Code allows a motorcycle rider who has come to a complete stop to proceed cautiously through a red light only if the signal fails to operate after one complete cycle, and the rider must yield to traffic in or approaching the intersection.
-
12. You reach a stretch of road covered by moving flood water of unknown depth. What is the correct decision?
Show answer
Answer D: Turn around and take another route
About a foot of moving water is enough to carry away most cars, and the roadbed under the water may already be washed out, so the only safe choice is to turn around.
-
13. How should a motorcycle helmet fit?
Show answer
Answer A: Snugly all the way around, without shifting or lifting off the head
A snug helmet stays in place during a crash, while one that moves or lifts can come off at the moment it is needed most.
-
14. 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.
-
15. What does Idaho law say about occupying the extreme left-hand lane?
Show answer
Answer B: You may not remain there long enough to impede other traffic traveling lawfully
Idaho prohibits operating a vehicle in the extreme left-hand lane for a period of time that impedes the flow of other traffic traveling at a lawful rate of speed.
-
16. A rider chooses an open face helmet. What does that choice make necessary?
Show answer
Answer A: Separate goggles or a face shield, because the face is uncovered
An open face helmet gives no eye or face protection, so the rider must add goggles or a face shield that will not shatter and that seals against the wind.
-
17. When is Idaho's one-time $15 motorcycle endorsement fee waived?
Show answer
Answer B: When the endorsement is added within one year of the instruction permit issue
The one-time $15 motorcycle endorsement fee is waived when the applicant meets the testing requirements and adds the endorsement within one year of being issued the motorcycle instruction permit.
-
18. Compared with dry pavement, how much room does a vehicle need to stop on packed snow?
Show answer
Answer D: Several times as much
Grip on packed snow is a fraction of that on dry pavement, so stopping distance grows several times over. Antilock brakes help you steer, not stop shorter.
-
19. Which clue tells you that a parked vehicle is about to pull into traffic?
Show answer
Answer D: Exhaust smoke, brake lights, front wheels turned out or a driver in the seat
A running engine, lit brake lights, turned wheels or a person behind the wheel all mean the vehicle may move. Slow down and give it room.
-
20. The signal turns green as you approach an intersection. What is the safest practice?
Show answer
Answer B: Look left, then right, then left again, and make sure the intersection is clear before entering
A green light gives permission but does not guarantee the intersection is empty, and a quick scan catches a vehicle running the red or a pedestrian still crossing.
-
21. 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.
-
22. A driver is tailgating you. Why is it a bad idea to tap or stab the brakes to warn them?
Show answer
Answer C: Because it cuts the little space they have and can cause a crash
Brake checking removes the small margin the tailgater has left and can provoke a collision; add space in front of you instead and let them pass.
-
23. A vehicle coming toward you has drifted into your lane. What should you do?
Show answer
Answer D: Slow down, sound the horn, flash your lights and steer to the right if possible
Moving right gives the other driver space to recover and keeps you out of the lane they are most likely to return to. Braking reduces the force of any impact.
-
24. You are making a U-turn at a signal on a green left arrow. Who must you still watch for?
Show answer
Answer D: People in the crosswalk you will cross as you come around
Even a protected arrow does not clear the crosswalk, and a U-turn sweeps across a crosswalk that pedestrians may already be using.
-
25. 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.
