40 questions. Pick an answer to see if it is right and why; you need 34 correct answers to pass.

  1. 1. You are entering an angle parking space on your right. What should you do?

    Show answer

    Answer C: Stay a little left of the space, then turn in between the lines

    Keeping a little left of the space gives the front wheels the room to turn in cleanly and leaves your car centered between the lines.

  2. 2. Why is wearing headphones over both ears a problem while driving?

    Show answer

    Answer D: You may not hear horns, sirens or other warning sounds

    Hearing is part of your awareness of traffic. Covering both ears blocks emergency sirens, horns and the sound of an approaching vehicle you cannot yet see.

  3. 3. A sign with a brown background and a white legend guides road users to

    Show answer

    Answer B: parks, campgrounds and other recreational or cultural sites

    Brown is reserved for recreational and cultural interest area signing, such as parks, historic sites and scenic areas.

  4. 4. How should a pregnant driver or passenger wear a seat belt?

    Show answer

    Answer A: Lap belt below the belly across the hips, shoulder belt across the chest

    A properly worn belt protects both mother and baby. The lap portion goes low under the belly, snug across the hip bones, and the shoulder belt crosses between the breasts.

  5. 5. How many alcoholic drinks does it take to begin affecting driving ability?

    Show answer

    Answer C: Even one drink can affect it

    A single drink can slow reactions and weaken judgment before you feel any change. Impairment starts long before a person feels drunk.

  6. 6. You have a green light and are turning right. Pedestrians are stepping off the curb into the crosswalk you are about to cross. What should you do?

    Show answer

    Answer B: Wait and let them cross before completing your turn

    A green light does not release a turning driver from yielding to pedestrians already in the crosswalk of the street being entered.

  7. 7. You have just been involved in a crash on a city street. Which sequence of first steps is correct?

    Show answer

    Answer A: Stop where you are, check everyone for injuries, and then make the scene safe

    You are required to stop, and the first priority at the scene is people, followed by preventing a second collision.

  8. 8. What is a driver being warned about here?

    A yellow diamond showing two black arrows, one pointing up and one pointing down
    Show answer

    Answer B: The pavement ahead carries vehicles traveling in the opposite direction

    Beyond this point vehicles come the other way on the same pavement, which commonly happens where a one-way section or a separated stretch comes to an end.

  9. 9. A bicyclist in the bike lane ahead of you signals and starts to move left toward the turn lane. What should you do?

    Show answer

    Answer A: Slow down and let the rider move across

    A bicyclist who needs to leave the bike lane to turn left is changing lanes like any driver, and following traffic should make room.

  10. 10. What do the grooves in a tire tread do on a flooded road surface?

    Show answer

    Answer B: They give the water a way to escape so the tread can touch the road

    Tread grooves pump water out from under the tire so rubber can meet pavement. A worn tread moves less water, so hydroplaning starts sooner.

  11. 11. Why are pedestrians and cyclists a special risk on unlit streets at night?

    Show answer

    Answer A: Dark clothing can make them invisible until they are very close

    A person in dark clothing reflects almost no light and may not appear until they are inside your stopping distance, so cut your speed where people may be about.

  12. 12. A driver passes this sign on an open road. Over what stretch does the figure it sets stay in force?

    A white vertical rectangle with a black border and black legend
    Show answer

    Answer A: From the sign onward, in every lane, until another sign sets a different figure

    The figure governs the road from the sign onward and binds every lane, and it stays in force until a later sign sets a different one.

  13. 13. You are traveling beside a solid white lane line. What does it tell you?

    Show answer

    Answer B: Crossing it is discouraged or prohibited, so stay in your lane

    A solid white line separates lanes going the same direction where lane changing is discouraged or prohibited, such as where a through lane meets a mandatory turn lane.

  14. 14. Why is repeatedly changing lanes to work through heavy traffic a poor idea?

    Show answer

    Answer A: It raises the crash risk and saves almost no time

    Each lane change adds a conflict with another vehicle, and in congestion the lanes move at similar average speeds, so the gain is negligible.

  15. 15. Why does this warning matter more on a motorcycle than in a car?

    A yellow diamond with black lettering
    Show answer

    Answer B: Because a sudden jolt can unsettle a two-wheeled machine and the rider can lose control

    A jolt can push a motorcycle off line or lift a wheel, so a rider slows early, comes slightly off the seat and keeps a relaxed but firm hold on the handlebars.

  16. 16. You are leaving a freeway on an exit ramp posted with an advisory speed of 25 mph. Where should you slow to that speed?

    Show answer

    Answer A: In the deceleration lane, before you reach the curve of the ramp

    Slowing belongs in the deceleration lane so you arrive at the curve already at the advisory speed and do not hold up traffic still in the through lanes.

  17. 17. Which steering method gives the most control when you must turn the wheel a long way at low speed?

    Show answer

    Answer C: Hand over hand, feeding the wheel from one hand to the other

    Hand over hand keeps both hands on the wheel through a large turn, so you never lose the ability to correct quickly.

  18. 18. You are following closely behind a vehicle you intend to pass on a two-lane road. What should you do first?

    Show answer

    Answer D: Drop back to give yourself room to build speed before you pull out

    From close behind you cannot see far enough ahead and you have no room to gather speed, so the pass takes longer and starts blind.

  19. 19. Which action becomes clearly more risky beyond this sign?

    A yellow diamond showing two black arrows, one pointing up and one pointing down
    Show answer

    Answer A: Using the left side of the roadway to overtake

    With vehicles coming the other way on the same pavement, overtaking on the left needs enough clear road to pull out, pass and return, which is often not available.

  20. 20. In Idaho, what alcohol concentration triggers the enhanced penalties reserved for excessive DUI levels?

    Show answer

    Answer D: .20 or more

    Idaho law provides stiffer penalties for a driver whose alcohol concentration is .20 or more, on top of the ordinary .08 threshold for drivers 21 and older.

  21. 21. A pedestrian is crossing a wide four-lane street and has reached the lanes on the far side. When may you go on?

    Show answer

    Answer C: Only after the person has finished crossing the roadway

    Waiting until the pedestrian has finished crossing is correct in every state and removes any doubt about how much clearance your state demands.

  22. 22. How far ahead should you normally be looking as you drive?

    Show answer

    Answer C: About 12 to 15 seconds ahead, well beyond the vehicle in front

    Looking that far down the road lets you see a problem developing and slow smoothly, instead of discovering it in time only for hard braking.

  23. 23. You wait in the aisle with your signal on for a space that is about to be vacated. What is the risk?

    Show answer

    Answer D: You block the aisle and drivers behind may try to squeeze past

    A stopped vehicle turns a two-way aisle into a bottleneck, and drivers who try to get around it pass close to pedestrians and reversing cars.

  24. 24. A curb sign reads No Standing. What does it allow you to do?

    Show answer

    Answer B: Stop only long enough to pick up or drop off passengers

    No Standing bars waiting for any purpose except the brief moment needed to let passengers in or out, which is stricter than No Parking.

  25. 25. On which approach is this sign normally installed?

    A yellow diamond showing a black T shape
    Show answer

    Answer C: On the road that ends, far enough ahead for the driver to slow down

    The warning belongs on the approach that terminates, placed early enough that the driver can lose speed and choose a direction before reaching the junction.

  26. 26. You are circulating in a roundabout and a vehicle is waiting to enter ahead of you. What should you do?

    Show answer

    Answer D: Keep going, because circulating traffic does not stop for entering vehicles

    Stopping in the circle to be polite surprises the drivers behind you and defeats the design; entering traffic is the side that waits.

  27. 27. A child seat was in the car during a moderate crash. What should be done with it?

    Show answer

    Answer A: Replace it, because a seat that has been through a crash may be weakened

    Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.

  28. 28. You are driving through a long curve on a road with two lanes in your direction. What is correct?

    Show answer

    Answer A: Stay within your own lane all the way through, adjusting speed before you enter

    Wandering out of your lane in a curve puts you into the path of a vehicle you cannot see, and the slowing belongs before the curve rather than in it.

  29. 29. A yellow lamp flashes above a warning sign at a sharp curve. What does it ask of a driver?

    Show answer

    Answer D: Slow down and pass the point with extra care

    A warning beacon draws attention to the sign it is mounted with, and the message of the sign is what the driver must act on.

  30. 30. Traffic is backed up beyond a railroad crossing. When may you start across the tracks?

    Show answer

    Answer B: Only when there is room for your whole vehicle on the far side

    Never enter a crossing you cannot clear; a vehicle stopped on the tracks in a queue has nowhere to go if the signals start.

  31. 31. You have stopped at a stop sign, but a parked truck blocks your view along the cross street. What should you do?

    Show answer

    Answer A: Creep forward slowly and stop again where you can see

    When something blocks the view, a second stop closer to the intersection is the only safe way to see, and it must come before your vehicle enters the traffic lane.

  32. 32. Why is it often safer to back into a parking space than to back out of one?

    Show answer

    Answer D: Because you leave the space going forward, with a clear view

    Backing into the space puts the difficult maneuver where you are stopped and looking around, and lets you drive out facing the traffic and pedestrians.

  33. 33. A bus stopped at the corner hides the crosswalk you are about to turn across. What should you do?

    Show answer

    Answer C: Turn slowly, ready to stop for anyone stepping out in front of it

    People often step into the road from in front of a stopped bus, so approach the hidden crosswalk slowly and be ready to stop.

  34. 34. The cars in front of and behind your parallel parked car have left you very little room. How do you get out?

    Show answer

    Answer D: Ease back and forth, turning the wheels each way, until you clear

    Short movements with the wheels turned first one way and then the other walk the car out of a tight space without touching anything.

  35. 35. Where among these is parking specifically prohibited?

    Show answer

    Answer A: On a bridge, in a tunnel or on railroad tracks

    Bridges and tunnels have no safe refuge and cannot be widened, and a vehicle left on railroad tracks cannot be avoided by an approaching train.

  36. 36. You are inside a tunnel with no shoulder when an ambulance comes up behind you with lights and siren. What should you do?

    Show answer

    Answer D: Keep going at a safe speed and pull over once you are clear of the tunnel

    Stopping in a tunnel or on a narrow bridge blocks the only lane, so continue at a safe speed to the first place where you can pull clear.

  37. 37. What is the right speed for a normal right turn at a city corner?

    Show answer

    Answer C: Slow enough to hold your lane and stop for a pedestrian

    A city right turn is tight and crosses a crosswalk, so the correct speed is one that keeps you inside your lane and still allows a stop.

  38. 38. What should you do as you approach your exit from a roundabout?

    Show answer

    Answer A: Signal right and check the crosswalk for pedestrians before leaving

    A right signal tells following drivers and waiting drivers that you are leaving, and pedestrians cross at the exit leg, so the crosswalk must be checked.

  39. 39. A pedestrian has stepped into a crosswalk at an intersection ahead of you. What is your obligation?

    Show answer

    Answer C: Yield and let the pedestrian finish crossing before you proceed

    Drivers must yield to pedestrians in a crosswalk, and an intersection has a legal crosswalk whether or not lines are painted on the pavement.

  40. 40. A sign shows a lane joining from the right with no merge required. What does that mean?

    Show answer

    Answer B: The joining traffic gets its own new lane, so nobody has to merge

    An added lane means the roadway gains a lane at that point, so entering vehicles have somewhere to go without anyone changing lanes.
