1. A sign on a long descent points to a RUNAWAY TRUCK RAMP a mile ahead. What is that ramp for?
Show answer
Answer C: Stopping a vehicle whose brakes have failed
An escape ramp climbs into deep gravel or sand to bring a vehicle with failed brakes to a halt, so no one should stop or park in it.
-
2. Once you have parallel parked, how close to the curb should your wheels be?
Show answer
Answer C: Within the distance your state allows, commonly 12 to 18 inches
Parking close to and parallel with the curb keeps the vehicle out of the traffic lane without damaging the tires; each state sets the exact maximum, usually 12 inches and 18 inches in some states.
-
3. When should you turn on your signal before a turn or a lane change?
Show answer
Answer C: Well before the maneuver, so other drivers have time to react
A signal is a warning to others, so it has to be given far enough ahead of the maneuver that drivers and pedestrians can adjust.
-
4. A set of reversible express lanes is closed off with gates and signs while it runs the other way. What must you never do?
Show answer
Answer C: Enter past a closed gate or a sign showing the lanes are closed
When reversible lanes are closed they may already be carrying traffic in the opposite direction, so entering past a gate can put you head-on into that traffic.
-
5. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?
Show answer
Answer D: Only at the openings where the solid lines are broken
The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.
-
6. The rear of your vehicle begins to slide sideways on a slippery surface. What is the correct correction?
Show answer
Answer C: Ease off the accelerator and steer in the direction you want the front of the vehicle to go
Looking and steering toward your intended path lines the front wheels up with the direction of travel, while sudden braking or a sharp opposite input usually makes the slide worse.
-
7. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
8. You are approaching the crest of a hill and cannot see the road beyond it. What should you do?
Show answer
Answer C: Slow down and keep well to the right
Beyond a blind crest there may be a stopped vehicle, a cyclist or an oncoming driver crossing the center line, so reduce speed and hold your own side.
-
9. You have fitted small convex blind spot mirrors to the door mirrors. What is true of them?
Show answer
Answer A: They help a good deal, but you should still look over your shoulder as well
Add-on mirrors reduce but do not remove the blind spot, and they make vehicles look smaller and further away.
-
10. A yellow pennant, an isosceles triangle with its long axis horizontal, is reserved for which message?
Show answer
Answer D: No passing zone
The pennant shape is used only for the no passing zone sign, which marks the point where overtaking is no longer allowed.
-
11. Apart from giving you room to stop, what else does a longer following gap do for you?
Show answer
Answer D: It widens your view of the road and the traffic ahead
Sitting further back lets you see past and around the vehicle in front, so hazards reach your eyes seconds earlier.
-
12. How must vehicles in an Idaho funeral procession be lit?
Show answer
Answer A: Headlights and tail lights on for all, with warning lights flashing on the first and last
Every vehicle in an Idaho funeral procession must show headlights and tail lights, and the first and last vehicles must also run warning lights to mark where the formation begins and ends.
-
13. You are behind three slow vehicles on a two-lane road and the way ahead looks clear. What is the sound decision?
Show answer
Answer D: Pass one vehicle at a time, if the road allows it
Passing several vehicles in one move keeps you in the oncoming lane far too long and leaves nowhere to go if a vehicle appears.
-
14. After a crash, what information should you exchange with the other driver?
Show answer
Answer B: Name, address, driver license, vehicle registration and insurance details
Identification, registration and insurance information are what the other party and the insurers need. Sensitive financial details are never required.
-
15. What is the maximum number of points an ITD-approved Defensive Driving Course can remove from an Idaho driving record?
Show answer
Answer D: Three points
An ITD-approved Defensive Driving Course removes a maximum of three points and may be used only once every three years; a law enforcement Traffic Safety Education Course can remove up to four.
-
16. You are parked legally, but a police officer tells you to move the vehicle. What should you do?
Show answer
Answer B: Move it as directed, because an officer overrides the signs
Directions from a police officer or a firefighter take precedence over signs and markings, whether they are directing traffic or clearing a street.
-
17. You are parking facing downhill on a street with a curb. Which way should the front wheels point?
Show answer
Answer A: Toward the curb, so the vehicle would roll into it if it moved
Turning the wheels toward the curb when facing downhill means a vehicle that starts to roll is stopped by the curb instead of entering the traffic lane.
-
18. You are about to pull out of a driveway when someone on the sidewalk is walking toward it. What should you do?
Show answer
Answer D: Wait, because traffic on the sidewalk has the right-of-way
A vehicle entering the roadway from a driveway yields to people on the sidewalk as well as to traffic on the street.
-
19. You have a green light at a school crossing, but the crossing guard steps out and holds up a stop sign toward you. What must you do?
Show answer
Answer A: Stop, because the crossing guard controls this crossing and outranks the signal
Directions from a crossing guard or a police officer take priority over signals and signs.
-
20. A sign at the intersection prohibits U-turns, but the opening looks wide and clear. What may you do?
Show answer
Answer B: Obey the sign and turn around somewhere else
A prohibition applies whatever the traffic looks like at that moment, usually because of sight distance or conflicts you cannot see from the lane.
-
21. You park in your own driveway and the rear of the vehicle sticks out over the sidewalk. What is wrong with that?
Show answer
Answer C: It blocks the sidewalk and forces people into the street
A vehicle overhanging the sidewalk pushes pedestrians, wheelchair users and strollers into the roadway, and blocking a sidewalk is prohibited.
-
22. A grade crossing is marked only with a crossbuck and has no lights or gates. What does the crossbuck require of you?
Show answer
Answer C: Yield to rail traffic and cross only when no train is approaching
The crossbuck requires road users to yield the right-of-way to rail traffic, so you must look and listen and be ready to stop.
-
23. You are approaching an uncontrolled intersection on a residential street where parked cars hide the cross street. What is the correct approach?
Show answer
Answer B: Slow enough to stop and creep out until you can see
Without a sign or signal you still have to be able to yield, and you cannot yield to traffic you have not seen.
-
24. 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.
-
25. How many questions may an applicant miss on the Idaho Class D knowledge test and still pass?
Show answer
Answer A: Six
The Idaho Class D knowledge test contains 40 questions and an applicant may miss up to six of them before failing.
-
26. How far should the driver chest be from the steering wheel?
Show answer
Answer B: At least about ten inches
The airbag deploys with great force in the first instants of a crash, so about ten inches between your chest and the wheel is the recommended minimum.
-
27. Idaho licenses drivers under 16 for daylight travel only. How does Idaho define daylight for this restriction?
Show answer
Answer D: From 5:00 a.m. to 10:00 p.m. local time
Idaho defines daylight for the under-16 restriction as 5:00 a.m. to 10:00 p.m. local time, unless a licensed driver at least 21 years old is in the front passenger seat.
-
28. On an undivided two-lane road you meet a school bus coming toward you with its red lights flashing and its stop arm out. What must you do?
Show answer
Answer C: Stop and wait until the red lights stop flashing
On an undivided road drivers in both directions must stop for a school bus loading or unloading, because children may cross in front of it.
-
29. What is wrong with slowing to a crawl at a stop sign and then rolling on through?
Show answer
Answer C: It is not a stop, and you may miss a pedestrian or cross traffic
A rolling stop is a violation and it also cuts short the moment you need in order to look carefully in each direction before entering.
-
30. What is the minimum training period for a student taking driver education through an Idaho public school?
Show answer
Answer C: Thirty days
ITD sets a 30-day minimum training period for public school driver education students, while commercial driver training schools are not held to a minimum period.
-
31. You are crossing a divided highway with a wide median. How should you treat the two roadways?
Show answer
Answer D: As two intersections, waiting in the median only when your vehicle fits
Each roadway of a divided highway is a separate intersection, and you should wait in the median only if it is long enough to hold your vehicle clear of both roadways.
-
32. You are driving at night through heavy falling snow. Which headlight setting works better and why?
Show answer
Answer C: Low beams, because high beams bounce off the falling flakes back at you
Falling snow reflects light the way fog does, so high beams build a white wall of glare while low beams still give a usable view.
-
33. 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.
-
34. A raised area crosses the roadway and carries a series of white markings on its face. What are those markings for?
Show answer
Answer A: To make the hump visible so drivers slow for it
Speed hump markings warn drivers that the pavement rises, which matters most at night or when the hump is in shadow.
-
35. What should you do about snow and ice on your vehicle before driving?
Show answer
Answer C: Clear all glass, mirrors and lights, and the roof and hood as well
Snow left on the roof or hood slides onto your windshield when you brake and blows into the path of drivers behind you, and covered lights make your vehicle hard to see.
-
36. How do stimulant drugs such as amphetamines or cocaine typically affect driving?
Show answer
Answer D: They can make the driver overconfident and more willing to take risks
Stimulants create a false sense of alertness and encourage aggressive, risky driving. When they wear off, sudden fatigue can follow.
-
37. A driver holds a steady highway speed into the section this sign warns about. What is the most likely result?
Show answer
Answer B: The vehicle runs wide toward the outside and can cross into another lane or leave the pavement
Holding speed into a change of alignment asks the tires for more side grip than they can supply, so the vehicle runs wide and the driver is left with less room to correct.
-
38. You are stopped in a shared through and right-turn lane with your right signal on, and a bicyclist rides up along your right side. What should you do?
Show answer
Answer A: Let the bicyclist clear the intersection or move ahead before you turn
A cyclist alongside your right side is in the path your turn will sweep across, so wait until that space is clear before turning.
-
39. You have turned onto a ramp at night and your headlights pick out large white arrows painted on the pavement pointing straight back at you. What do they mean?
Show answer
Answer C: You are traveling against the flow and must turn back
Wrong-way arrows are laid so that a driver going the correct way never sees them head on, so an arrow pointing at you means you are on the ramp backwards.
-
40. You are using the parking brake to slow a vehicle whose brakes have failed. How should you apply it?
Show answer
Answer D: Gradually, holding the release so you can let it off if the rear slides
The parking brake works on two wheels only, so applying it hard can lock them and spin the vehicle. Keep the release held so you can back it off instantly.
