1. The traffic around you is moving well above the limit on a wide highway. What should you do?
Show answer
Answer D: Keep to the limit and stay to the right, letting faster traffic pass
The limit is a legal maximum, and the safe way to differ from the traffic around you is to keep right and let it go by.
-
2. What does a yield sign require of a driver?
Show answer
Answer A: Slow down, and stop when necessary, so conflicting traffic can go first
A yield sign obliges the driver to reduce to a speed suited to conditions and to stop when needed so that conflicting traffic or pedestrians are not interfered with.
-
3. Fog thickens until you can barely make out the vehicle ahead. What is the safest action?
Show answer
Answer A: Slow right down and, if needed, leave the road at a safe place
In heavy fog the only safe speed may be very low, and if it drops below what the road allows, the answer is to pull well clear of the traffic lanes.
-
4. You are involved in a collision, even a minor one. What is your first legal duty?
Show answer
Answer A: Stop at or near the scene without blocking traffic more than necessary
Every driver involved in a crash must stop at the scene, and leaving before meeting that duty is a serious offense. Move the vehicles only as far as needed to clear the traffic lanes.
-
5. A traffic signal is dark and you reach the intersection at the same moment as a vehicle on your right. Who goes first?
Show answer
Answer A: The vehicle on your right, as at any all-way stop
A dark signal is treated as an all-way stop, and the usual tie-breaker then applies: the vehicle on the right goes first.
-
6. Why is a U-turn on a one-way street a problem?
Show answer
Answer A: You would end up facing the wrong way against all the traffic
Every lane of a one-way street runs the same way, so turning around leaves you driving head-on against all of the traffic.
-
7. What does a tire with worn tread do on a wet road?
Show answer
Answer B: It loses grip and it hydroplanes at a lower speed than a good tire
Tread grooves carry water away from the contact patch, and a worn tire cannot do that, so it floats on the water sooner.
-
8. What is the sensible way to handle a meal on a long drive?
Show answer
Answer D: Eat before you leave or stop to eat
Eating takes hands, eyes and attention, and the only version with no cost to your driving is the one that happens while the car is parked.
-
9. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
10. You are turning left from a two-way street onto a one-way street. Which lane should you enter?
Show answer
Answer C: The first lane open to traffic on the left side of the one-way street
Turn left from the lane closest to the center line and finish in the first available lane on the left of the one-way street, then change lanes if you need to.
-
11. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.
-
12. You are parking facing uphill on a street with a curb. What is the correct wheel position?
Show answer
Answer B: Turn the front wheels away from the curb and let the vehicle roll back until a tire touches it
Facing uphill the vehicle would roll backward, so the wheels point away from the curb and the tire is rested against it to act as a block.
-
13. A sign with a blue background and a white legend and border tells road users about
Show answer
Answer A: services such as fuel, food, lodging, hospitals and rest areas
Blue is the background of the general service series, which points travelers toward the services available along or near the route.
-
14. You enter a work zone at night where one lane is closed and a flagger is on duty. What is the safest approach?
Show answer
Answer A: Slow early, merge before the closure and be ready to stop
Merging early at a reduced speed keeps the queue orderly and leaves you room to stop for equipment, workers or traffic that has halted ahead.
-
15. You are backing a trailer and want its rear to move to the left. Which way should you turn the steering wheel?
Show answer
Answer A: Move the bottom of the wheel to the left, which turns the top to the right
A trailer moves opposite to the tow vehicle's steering when backing. Holding the wheel at the bottom and moving your hand in the direction you want the trailer to go makes this easier.
-
16. 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.
-
17. How far ahead must Idaho headlights reveal people and vehicles?
Show answer
Answer A: At least 350 feet on high beam and at least 100 feet on low beam
Idaho requires high beams to show people and vehicles at least 350 feet away and low beams to light the roadway at least 100 feet ahead.
-
18. You are calling 911 to report a crash. Which information matters most?
Show answer
Answer C: The exact location, how many people are hurt and any hazard such as fire
Dispatchers need to know where to send help, how much help to send, and what dangers the crews will meet on arrival.
-
19. How can you keep space at the sides of your vehicle in heavy traffic?
Show answer
Answer D: Drive in the gaps between the other vehicles rather than beside them
Travelling in the open spaces rather than alongside others keeps a way out open on at least one side.
-
20. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
-
21. You are parking on a hill where there is no curb, whether facing up or down. Which way should the front wheels point?
Show answer
Answer B: Toward the shoulder, so the vehicle would roll away from the traffic lanes
With no curb to stop the vehicle, the wheels are turned toward the edge of the road so that a runaway vehicle leaves the roadway instead of entering it.
-
22. You have stopped after a crash. Why should the engines of the vehicles involved be switched off?
Show answer
Answer A: To reduce the risk of a fire starting around any fuel that has spilled
Crashes often break fuel lines, and a running engine is a source of ignition, so switching off lowers the risk of fire.
-
23. You have a green arrow to turn left. What still applies?
Show answer
Answer D: You must yield to any pedestrian or vehicle still inside the intersection
A green arrow protects your turn from conflicting traffic, but you must still let anyone already in the intersection get clear before you move.
-
24. You are towing a loaded trailer for the first time. How should you drive?
Show answer
Answer A: Slow earlier and keep a longer following gap
A trailer adds weight and length, so stopping takes longer and every maneuver needs more room and more warning.
-
25. What is the usual result of driving well above the flow of traffic on a typical trip?
Show answer
Answer B: Very little time saved, with much greater risk
Signals, traffic and short distances swallow the theoretical gain, while crash risk and crash severity both climb sharply with speed.
-
26. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
-
27. You are driving slower than the general flow on a multilane highway. Which lane should you use?
Show answer
Answer D: The right lane, keeping the left lanes free for faster traffic and passing
Slower traffic must keep right so that faster vehicles and overtaking traffic can use the left lanes without weaving between lanes.
-
28. What most often starts a rear wheel skid?
Show answer
Answer A: Too much speed, braking or acceleration for the grip available
A skid begins when what you ask of the tires exceeds what the surface can give, which is usually a matter of speed and of how abruptly you use the controls.
-
29. The steering suddenly becomes very heavy while you are driving. What has happened and what should you do?
Show answer
Answer C: The power steering has failed, so steer with more effort and pull over
Loss of power assistance leaves the steering usable but very heavy. Keep both hands on the wheel, slow gradually and pull off the road to check it.
-
30. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?
Show answer
Answer D: Slow or stop and let the person reach safety
Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.
-
31. Where is the no passing zone pennant sign installed?
Show answer
Answer A: On the left side of the roadway
The pennant is placed on the left side of the roadway at the beginning of the no-passing zone, in the field of view of a driver who is thinking about overtaking.
-
32. Another driver takes a right of way that was legally yours. What should you do?
Show answer
Answer A: Give way to the other driver and avoid the crash, whatever the law says
Right of way is something you give, not something you take, and being in the right is no protection in a collision.
-
33. A funeral procession with headlights on is crossing an intersection when your light turns green. What should you do?
Show answer
Answer A: Wait and let the whole procession go through
Most states let a funeral procession stay together once the lead vehicle has lawfully entered an intersection, and in every state you must yield to vehicles already in the intersection, so wait until the line has passed.
-
34. You see an open curb space on the opposite side of a two-way street. What should you do?
Show answer
Answer B: Drive on, turn around, and come back on that side
You must park on the right, facing the direction of travel, so reaching a space on the other side means going around rather than crossing into it.
-
35. You have brought the vehicle under control after a blowout. What should you do next?
Show answer
Answer A: Signal and coast well off the road before stopping
Let the speed fall, signal, and leave the roadway as far from traffic as you can before you stop. Driving on a failed tire ruins the wheel and risks control.
-
36. A vehicle in front of you has already begun turning left into a driveway when the gap you were waiting for opens up. What should you do?
Show answer
Answer B: Wait and let that driver finish the turn
A vehicle that has lawfully started a maneuver keeps the right of way until it is finished.
-
37. You approach a stopped tow truck with lights flashing on an Idaho road with one lane in each direction. What does the law require?
Show answer
Answer C: Reduce speed below the posted limit and proceed with caution
Idaho requires drivers to reduce speed below the posted limit and proceed with caution; the additional duty to change lanes applies only where there are two or more lanes in the same direction.
-
38. The hood of your vehicle flies open while you are driving and blocks your view. What should you do?
Show answer
Answer A: Look through the gap beneath the hood or out the side window, slow down and pull off the road
You usually still have a narrow view under the raised hood or through the side window. Use it to steer, slow gradually and get clear of traffic before securing the hood.
-
39. The word SCHOOL is painted in large letters across the roadway. What is it doing?
Show answer
Answer D: Backing up the signs marking a school zone
Word markings on the pavement reinforce a message that is already signed, and a driver looking at the road ahead cannot miss them.
-
40. Why should you not leave the engine running when you walk away from your vehicle?
Show answer
Answer C: Because the vehicle can be stolen or can move on its own
An unattended running vehicle is an easy theft and, if the transmission slips or is knocked out of park, it can roll away with nobody at the wheel.
