1. You are in the middle of an intersection when you hear a siren and see an emergency vehicle approaching. What should you do?
Show answer
Answer A: Keep going, clear the intersection, then pull to the right and stop
Stopping inside an intersection blocks the emergency vehicle. Clear the intersection first, then pull over to the right and stop.
-
2. You are driving on a rural road with no sidewalk. Where should you expect to meet pedestrians?
Show answer
Answer A: Walking toward you on your side of the road
Where there is no sidewalk, pedestrians are taught to walk facing traffic, so they appear on your side of the road coming toward you.
-
3. You are driving at night on an unlit road using low beams. How should you choose your speed?
Show answer
Answer C: So you could stop within the distance your headlights light up
Driving faster than you can stop within the lit area is called overdriving your headlights. Anything beyond the beam is invisible until it is too late to react.
-
4. You are approaching the entry of a roundabout and a pedestrian is crossing the marked crosswalk on your approach lane. What must you do?
Show answer
Answer D: Stop before the crosswalk and let the pedestrian cross
Roundabout crosswalks sit a short distance back from the yield line, and drivers must yield there before they ever reach the circulating lanes.
-
5. What is the purpose of a wide solid white line painted straight across your lane on the approach to an intersection?
Show answer
Answer C: It shows the point where a required stop must be made
A stop line indicates the point at which the stop required by a signal or a stop sign is to be made, ahead of the crosswalk and the intersection.
-
6. Why is a shoulder check especially important on a road with motorcycles and bicycles?
Show answer
Answer D: A narrow vehicle can disappear completely in the blind spot
A motorcycle or a bicycle is small enough to be hidden entirely by a door pillar or by the blind spot the mirrors do not cover.
-
7. You are the second vehicle waiting to turn left on a green ball. Where should you wait?
Show answer
Answer A: Behind the stop line, until the first vehicle has actually turned
Only the lead vehicle should move into the intersection to wait; a second vehicle inside it is likely to be stranded there when the light changes.
-
8. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
9. Why should the shoulder belt never be worn under the arm or behind the back?
Show answer
Answer C: In a crash it could not hold your upper body and could cause severe injury
The shoulder belt restrains your chest and head. Placed under the arm it concentrates crash force on the ribs and organs; behind the back it does nothing at all.
-
10. What does a steady yellow traffic light tell the driver facing it?
Show answer
Answer A: The green movement is ending and a red indication is about to appear
A steady yellow warns that the related green movement is being terminated and that red will follow, so you should stop if you can do so safely.
-
11. A tow truck with flashing amber lights is loading a car on the shoulder ahead. How should you treat it?
Show answer
Answer B: Give it the same room as an emergency vehicle
Tow operators, utility crews and highway workers face the same danger from passing traffic, so move over or slow down for their flashing amber lights too.
-
12. When are the hazard warning lights properly used?
Show answer
Answer A: When your vehicle is stopped or barely moving and is a hazard
Hazard lights warn that your vehicle is an obstruction; they do not authorize illegal parking and they hide your turn signals while driving.
-
13. At an intersection that uses a lagging left turn, when is the left-turn arrow displayed?
Show answer
Answer B: After the through movement has run
A lagging left turn phase runs at the end of the green rather than the start, so a driver waiting to turn should not assume the arrow has been missed.
-
14. Where in the United States may a motorcycle ride between lanes of traffic?
Show answer
Answer C: Only where a state has specifically authorized it
Riding between lanes is prohibited in most states and permitted only where a state law expressly allows it, so a rider must know the rule for the state being ridden in.
-
15. What do flashing yellow lights on a school bus mean?
Show answer
Answer A: The bus is about to stop to load or unload, so prepare to stop
The amber lights are the warning phase that comes before the red lights and the stop arm, so drivers should slow down and get ready to stop.
-
16. At 45 mph you look at a navigation screen for four seconds. Roughly how far do you travel unseeing?
Show answer
Answer D: About 260 feet
At 45 mph you cover roughly 66 feet a second, so four seconds on a screen is around 260 feet of road that you never looked at.
-
17. At what distances must Idaho headlamps be dimmed?
Show answer
Answer D: 500 feet before meeting an oncoming vehicle and 200 feet before overtaking one
Idaho requires high beams to be dimmed 500 feet before meeting another vehicle and 200 feet before overtaking one.
-
18. Why is this restriction used so often on a divided road just before a crest or a bend?
Show answer
Answer A: Because a vehicle turning across the median there stays hidden from approaching drivers until it is too late
The maneuver needs a long gap and good visibility, and where sight distance is short an approaching driver has no time to react to a vehicle turning across the road.
-
19. You are on a four-lane divided highway and a vehicle in your lane is stopped waiting to turn left across the median. What is the normal way past?
Show answer
Answer D: Slow down and go by in the lane to the right when it is clear
On a multilane road the free lane beside you is the lawful place to go past a vehicle waiting to turn, and the median is not part of the roadway.
-
20. A pedestrian signal changes to a flashing upraised hand. What does that indication mean?
Show answer
Answer C: Do not start crossing, but finish a crossing already begun
The flashing upraised hand is the pedestrian change interval: nobody may start to cross, but a pedestrian already in the crosswalk may continue to the far side or to a median.
-
21. Why should the washer reservoir hold proper washer fluid rather than plain water in winter?
Show answer
Answer D: Water freezes and it leaves you with no way at all to clean the glass
Washer fluid contains antifreeze, so it still works in the cold, whereas water freezes in the reservoir and the lines.
-
22. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
23. This sign leads to a crossing that has no gates and no flashing lights. What does that mean for the driver?
Show answer
Answer D: Nothing will warn of an approaching train, so the driver must check the tracks personally
At a passive crossing there is no active device to announce a train, so the whole judgment rests on the driver, who must approach slowly enough to stop after looking along the track.
-
24. Which sequence describes a well-made turn?
Show answer
Answer A: Signal, move into the correct lane, slow down, check, then turn
Tell others first, take your position, lose the speed before the corner, take a final look, and only then steer through the turn.
-
25. A sign with a green background and a white legend normally provides
Show answer
Answer A: directions, distances and destinations
Green is the background color of the guide sign series, which names routes and destinations and gives the distance to them.
-
26. A flashing red arrow is displayed for your turning lane. What does it require?
Show answer
Answer D: Stopping, then turning when the way is clear
A flashing red arrow is treated like a stop sign for that movement: come to a full stop, then turn when it is safe and no one has to be cut off.
-
27. You drive away and the car feels sluggish while a warning light glows on the dash. What is a likely cause?
Show answer
Answer B: The parking brake was left partly applied
Driving with the parking brake partly on overheats the rear brakes and can ruin them, so release it fully and check that the warning light goes out.
-
28. What license suspension does a first Idaho DUI conviction carry for a driver 21 or older?
Show answer
Answer D: At least 90 days and up to 180 days, with no driving privileges for the first 30
A first Idaho DUI conviction brings a mandatory suspension of at least 90 days and up to 180 days, with absolutely no driving privileges during the first 30 days.
-
29. A driver passes this sign and the signal beyond it is already showing green. What is the safest response?
Show answer
Answer C: Ease off the accelerator and be ready to stop, because an indication that has been showing for a while is about to change
A signal that has been displaying the same indication for some time is close to changing, so arriving at a controlled speed with the brake covered is safer than accelerating to beat it.
-
30. A law enforcement officer is directing traffic and waves you forward while the signal facing you shows red. What should you do?
Show answer
Answer A: Follow the officer's direction and proceed
Directions given by an officer controlling traffic take priority over signals, signs and pavement markings.
-
31. Four vehicles reach a four-way stop from all four directions at the same instant. How is the deadlock resolved?
Show answer
Answer C: Each driver yields to the vehicle on the right and they go one by one
Yielding to the right applies to every driver, so the group untangles itself as drivers take turns rather than moving together.
-
32. Your left-turn lane faces a steady green ball and oncoming traffic is heavy. What are you allowed to do?
Show answer
Answer C: Move into the intersection and turn when a safe gap appears
A green ball permits the turn but gives no priority, so you may move into the intersection and wait there for a gap in the oncoming traffic.
-
33. What is the driver expected to do after passing this sign?
Show answer
Answer A: Begin slowing so that a complete stop can be made at the intersection ahead
It is used where the control at the intersection stays hidden until late, so braking should begin here rather than at the stop line.
-
34. Fresh snow covers the road and earlier vehicles have left clear tracks. What line is usually best?
Show answer
Answer B: The existing tracks, where more of the tire can reach the surface
Running in the cleared tracks puts more rubber on the road surface than ploughing through loose snow, provided the tracks have not turned to polished ice.
-
35. Where do you find how much weight your vehicle may carry?
Show answer
Answer C: On the placard in the driver door opening
The certification placard in the driver door opening gives the load limit and the recommended cold tire pressures for the vehicle as built.
-
36. What is the basic rule for entering a roundabout?
Show answer
Answer B: Traffic already circulating goes first, and you wait for a gap
Entering traffic yields to vehicles already going around the circle, which is what keeps a roundabout moving instead of locking up.
-
37. Why is an underinflated tire especially risky on a long drive in hot weather?
Show answer
Answer C: It flexes more, builds up heat and can fail at speed
A soft tire flexes on every rotation, and that flexing makes heat that the hot road and high speed add to until the tire can come apart.
-
38. You reach a stop-controlled intersection at the same time as a driver on your left, but that driver is already moving through the crossing. Who goes first?
Show answer
Answer C: The driver who is already inside the intersection
A vehicle already in the intersection has the right of way, and the rule about yielding to the right applies only before anyone has entered.
-
39. You are approaching a yield sign and no other vehicle is anywhere in sight. What does the sign require?
Show answer
Answer A: Slow down and be ready to stop, but stop only if needed
A yield sign requires you to slow and give way, and to stop only when traffic or pedestrians make stopping necessary.
-
40. You are stopped inside an intersection waiting for a gap to turn left. How should your front wheels be positioned?
Show answer
Answer C: Pointing straight ahead until you actually begin the turn
If your wheels are already turned left and another vehicle strikes you from behind, you would be pushed into oncoming traffic.
