1. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?
Show answer
Answer D: The sign that forbids entering that roadway at all
The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.
-
2. A broken white line separates your lane from the lane beside it. What does it indicate?
Show answer
Answer C: Both lanes carry traffic in the same direction and lane changes are permitted
White lines separate lanes of traffic moving in the same direction, and a broken white line means changing lanes across it is permitted when it is safe.
-
3. Why is parking too close to a street corner prohibited?
Show answer
Answer D: Because it hides approaching traffic and pedestrians
A vehicle parked at a corner blocks the view that both drivers and pedestrians need before entering the intersection.
-
4. On a divided highway you see a median opening marked for authorized vehicles only. May you use it to turn around?
Show answer
Answer D: No, those openings are for emergency and maintenance vehicles
Official crossovers are reserved for emergency and highway maintenance use; turning there puts a slow vehicle across high-speed traffic.
-
5. When does an Idaho driver training permit issued to a 15-year-old expire?
Show answer
Answer D: Five days after the permit holder's 18th birthday
A driver training permit expires five days after the holder's 18th birthday; holders who are already 17 and a half or older instead receive a permit lasting 180 days.
-
6. What does ITD allow inside the knowledge testing area at an Idaho county driver's license office?
Show answer
Answer B: Nothing electronic, and no manuals or written notes either
ITD bars electronic devices of every kind from the testing area, along with driver manuals and other written material.
-
7. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
8. You park facing downhill on a one-way street where the curb is on your left. Which way do the front wheels go?
Show answer
Answer A: Left, toward the curb on that side
Standard practice follows the curb rather than the side of the road: facing downhill the wheels point into the curb so a rolling vehicle is stopped by it. States differ on whether this is legally required.
-
9. May you stop briefly across the sloped ramp that joins the sidewalk to the street at a corner?
Show answer
Answer B: No, that ramp must stay clear for people using wheelchairs
A curb ramp is the only way many people can get from the sidewalk to the crosswalk, so blocking it even briefly is prohibited.
-
10. Your tires drop into deep slush that has built up between the travel lanes. What should you do?
Show answer
Answer B: Ease off the accelerator and grip the wheel, since slush tugs the vehicle
Slush grabs at the tires and can pull the vehicle sideways. Reduce power gently, hold the wheel firmly and avoid sudden steering or braking.
-
11. You have just had bad news and you feel very upset. What should you do?
Show answer
Answer B: Wait until you have calmed down, or else let somebody else drive
Strong emotion takes attention away from the road as surely as alcohol or fatigue, so it is a reason not to drive yet.
-
12. You turn left onto a road that has a center two-way left-turn lane. In which lane should you be traveling once the turn is finished?
Show answer
Answer D: The first through lane to the right of the center turn lane
The shared center lane is only for turning movements, so even where a state lets you pause in it to merge you must end up in the first ordinary travel lane beside it.
-
13. A truck passes you in heavy rain and its spray blanks out your windshield. What should you do?
Show answer
Answer B: Hold the wheel steady, ease off slightly and let the wipers clear it
The blackout lasts a second or two. Keeping your line and easing off is far safer than braking hard or steering blind toward the shoulder.
-
14. You are about to pass a bicyclist on a narrow two-lane road. What is the correct way to do it?
Show answer
Answer A: Wait for a clear gap and move well left, giving the rider wide space
Pass a cyclist as you would a car: wait for clear road, change lane position to leave generous clearance, and return only when the rider is well behind you.
-
15. While you are still on an entrance ramp, where should your attention be?
Show answer
Answer D: Along the ramp ahead and back at the highway traffic in the mirrors and over your shoulder
A merge needs both halves of the picture at once: the ramp curving ahead of you and the traffic you are about to join behind and to your left.
-
16. 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.
-
17. The brake pedal goes to the floor and the vehicle does not slow. What should you try first?
Show answer
Answer C: Pump the pedal quickly to try to build pressure
Most vehicles have a split braking system, so rapid pumping can often build enough pressure to slow you. If it does not, use the parking brake gradually.
-
18. You are traveling in the same direction as a funeral procession and want to get ahead of it. What should you not do?
Show answer
Answer B: Driving in between the vehicles of the procession
Most states prohibit driving into or through a funeral procession, and cutting into the line leaves the drivers behind with no lead vehicle to follow, so go around only where passing is permitted.
-
19. A reduced speed limit posted with this sign and a plaque giving hours is in force
Show answer
Answer C: during the hours shown on the plaque, or while the beacon is flashing
A school speed limit applies during the periods stated on the plaque or while the attached beacon flashes, and the regular limit governs outside those periods.
-
20. Your car begins to lose power on a freeway and you must stop. Where should you try to bring it to a halt?
Show answer
Answer A: As far off the right side of the road as you can get, beyond the edge line
A disabled vehicle should be moved completely clear of the travel lanes, on the right, so that traffic can pass without changing course.
-
21. Why is it useful to watch the vehicle two or three places ahead of you?
Show answer
Answer C: You get an earlier warning of slowing traffic than brake lights give
Trouble travels back through a line of traffic, so seeing it start several vehicles ahead gives you a head start on braking.
-
22. Your vehicle has daytime running lights. Why should you still switch on the headlights at dusk?
Show answer
Answer B: Daytime running lights usually do not light the tail lights, so you are hard to see from behind
On many vehicles the daytime running lights illuminate only the front. Without the headlight switch on, the rear of the vehicle stays dark and the dash may still look lit.
-
23. Under Idaho's Drive Insured program, what follows two consecutive months with no insurance coverage on file for a vehicle?
Show answer
Answer B: A warning is sent and the owner has 30 days to show proof or obtain an exemption
Idaho verifies insurance electronically, sends a warning after two consecutive months without coverage and allows 30 days to provide proof or obtain an exemption before suspending the registration.
-
24. Which headlight setting should you use in dense fog?
Show answer
Answer B: Low beams
High beams reflect off the water droplets in fog and bounce glare back at you, while low beams aim downward and light the road without that mirror effect.
-
25. You are descending a long steep grade with a loaded truck close behind you. What should you do?
Show answer
Answer A: Hold a steady speed and let it pass when it can
Gravity pushes a loaded truck downhill and it cannot slow quickly, so give it a predictable speed and room to get by rather than braking in front of it.
-
26. A bicyclist is riding around a single-lane roundabout in the middle of the lane as you wait to enter. What is your duty?
Show answer
Answer C: Yield to the bicyclist just as you would to a car
A bicyclist using the roundabout is traffic like any other vehicle and has the same claim to the circulating lane.
-
27. You reach an uncontrolled intersection at the same moment as a vehicle approaching from your left. What should you do?
Show answer
Answer A: Proceed, but only once you see that driver slowing
You have the right of way over the vehicle on your left, but a right of way is something the other driver has to give, so confirm it before you commit.
-
28. How does a NO OUTLET sign differ from a DEAD END sign?
Show answer
Answer B: It warns that a whole group of streets has no way out
No Outlet is posted where the road leads into a network of streets from which there is no through route, while Dead End refers to the single street itself.
-
29. On a busy multilane highway, where is the best place to travel?
Show answer
Answer B: In a gap in the traffic, with space open on both sides
Travelling in a gap keeps escape routes open on both sides, while riding alongside other vehicles removes the room you would need to swerve.
-
30. What is the only reliable remedy for a driver who is sleepy?
Show answer
Answer A: Sleep
Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.
-
31. A steady green downward arrow is displayed above the lane you are in. What does it tell you?
Show answer
Answer A: You may drive in that lane
A green downward arrow means the lane beneath it is open for travel in your direction.
-
32. You leave your car so that its rear overhangs a marked crosswalk. What is wrong with that?
Show answer
Answer B: Pedestrians must step around it into the traffic lane
A crosswalk has to stay completely clear; anything sticking into it pushes people on foot out into the path of moving vehicles.
-
33. No plaque stating days or hours accompanies this sign at the intersection. When does the restriction apply?
Show answer
Answer D: At all times, since nothing limits it to particular periods
A regulatory restriction runs continuously unless a supplemental plaque states the days or hours during which it applies.
-
34. Your left-turn lane shows a flashing yellow arrow. What does that indication allow?
Show answer
Answer B: A left turn after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow marks a permissive left turn: the movement is allowed, but oncoming vehicles and pedestrians keep the right-of-way.
-
35. You correct a rear wheel skid and the back of the vehicle swings the other way. Why?
Show answer
Answer D: You steered too far, so be ready to correct back the other way
Over correcting sends the tail past straight and starts a second skid the opposite way. Steer smoothly and be ready to unwind the correction.
-
36. Permanent signs must be retroreflective or lighted so that
Show answer
Answer A: they show the same shape and color at night as by day
Retroreflective sheeting throws headlight light back to the driver, so a sign keeps its daytime shape and color after dark.
-
37. You have stopped on an uphill grade close behind a large truck at a traffic signal. What is the risk?
Show answer
Answer B: The truck may roll back into you when it starts to move
Heavy vehicles can roll backward a short distance when the driver moves from the brake to the accelerator on a hill. Leave extra room when stopped behind a truck on a grade.
-
38. The sign over the leftmost lane reads LEFT LANE MUST TURN LEFT. You are in that lane and want to go straight. What should you do?
Show answer
Answer C: Move out of the lane before the intersection if it is safe
A mandatory movement lane control sign makes the turn compulsory for that lane, so a driver who wants another movement must change lanes in advance.
-
39. A school sign combined with an AHEAD plaque, or with a plaque giving a distance in feet, forms an assembly that
Show answer
Answer B: warns of a school crossing located further along the road
The school advance crossing assembly is placed before the crosswalk to give drivers notice, while a different assembly marks the crossing itself.
-
40. You have finished a distracting task and your eyes are back on the road. What is true?
Show answer
Answer A: Your full attention takes a while to come back
Studies of drivers show attention lags behind the eyes for many seconds after a phone or a screen task, so the danger continues after the task is over.
