1. What must a driver be ready for beyond this sign?
Show answer
Answer C: Vehicles approaching from the opposite direction in the next lane over
The separation between the two directions runs out, so from that point oncoming vehicles share the same pavement and the driver has to keep right.
-
2. Your vehicle is stuck in deep snow and you run the engine for heat while waiting for help. What must you check?
Show answer
Answer C: That the exhaust pipe is clear of snow
Snow packed around the tailpipe pushes exhaust back into the cabin, and carbon monoxide can kill without warning. Clear the pipe and crack a window open.
-
3. The trapezoid sign shape is associated with
Show answer
Answer C: recreational and cultural interest area signing
The trapezoid is used for recreational and cultural interest area guide signs and for national forest route markers.
-
4. Why should you make sure your turn signal has stopped flashing after a lane change?
Show answer
Answer A: A signal left flashing tells other drivers that you intend to move again
Other drivers act on your signals, so one that is left on gives them false information about what you are about to do.
-
5. Traffic is backed up on the far side of a railroad crossing. What should you do before driving onto the tracks?
Show answer
Answer D: Wait behind the tracks until there is room to clear them completely
Never enter a crossing until you are certain you can drive completely across without stopping, because a vehicle trapped on the tracks cannot get out of a train's way.
-
6. The red brake warning light stays on after you release the parking brake. What should you do?
Show answer
Answer D: Stop safely and have the brakes checked before driving on
With the parking brake released, that light points to low fluid or a fault in one half of the braking system, which can leave you with very little braking.
-
7. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
8. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
9. An officer directing traffic faces you and holds one hand up with the open palm toward your vehicle. What does the gesture mean?
Show answer
Answer D: Stop before reaching the officer
A raised open palm shown toward a driver is the standard signal to stop.
-
10. At which location is this sign normally installed?
Show answer
Answer D: Facing traffic that could turn into a one-way roadway or ramp against the flow
It is posted where a driver could otherwise enter a ramp or a one-way roadway from the wrong end, so it faces exactly the traffic that has to be kept out.
-
11. The accelerator sticks open while you are driving. What is the first thing to do?
Show answer
Answer A: Shift into neutral and brake while steering off the road
Neutral disconnects the engine from the wheels so the vehicle can be braked normally, while shutting off the ignition may lock the steering and remove power assistance.
-
12. You are in a passing zone that continues over the crest of a hill ahead. May you start a pass?
Show answer
Answer B: Only if you can finish it well before the crest
Beyond the crest you cannot see oncoming traffic, so any part of the pass that happens there is being made blind.
-
13. You come upon a crash that has just happened and decide to help. Where should you stop your vehicle?
Show answer
Answer A: Well beyond the scene, completely off the road, with the hazard lights on
Stopping past the crash and off the pavement keeps you from becoming another victim and leaves the approach clear for emergency vehicles.
-
14. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?
Show answer
Answer A: Behind the stop line, so that the crosswalk stays clear
Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.
-
15. What do white lane lines painted between travel lanes indicate?
Show answer
Answer A: Traffic in the adjacent lane moves in the same direction as you
White markings separate lanes carrying traffic in the same direction and mark the right edge of the roadway.
-
16. You have just merged onto a freeway from an entrance ramp. What should you do next?
Show answer
Answer C: Settle into the right lane and build up speed before changing lanes
Crossing lanes while you are still below the speed of the traffic forces other drivers to brake, so the speed comes first and the lane change second.
-
17. Beyond the point this sign refers to, which movement becomes unlawful?
Show answer
Answer D: Driving on the far side of the separation, against the flow
Once the two directions are separated, each roadway carries one-way traffic, so crossing to the other side means driving into oncoming vehicles.
-
18. What is the best way to keep your phone from distracting you on a trip?
Show answer
Answer D: Silence it and stow it before you start
A phone you cannot hear and cannot reach cannot tempt you, which is far more reliable than deciding case by case while you drive.
-
19. After a crash your door will not open and you need to get out of the car. What should you try?
Show answer
Answer B: Try another door of the vehicle, or a window that will still open properly
A jammed door is common after an impact, and the simplest escape is a different door or a window rather than forcing the damaged one.
-
20. Which vehicle is most affected by a strong side wind?
Show answer
Answer D: A van or a car towing a tall trailer
Wind pushes against the side area of a vehicle, so tall boxy shapes and trailers are moved far more than low heavy ones.
-
21. What should a driver expect a short distance beyond this sign?
Show answer
Answer C: Another road crossing the one being traveled
Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.
-
22. The center line beside your lane is a broken yellow line. What does it allow?
Show answer
Answer D: You may cross into the opposing lane to pass when it is safe and clear
A broken yellow center line marks a passing zone where traffic in that direction may cross into the opposing lane to pass when the way ahead is clear.
-
23. You are about to open your door after parking on the traffic side of the street. What should you do first?
Show answer
Answer C: Check the mirror and look back for approaching vehicles and bicyclists before opening the door
A door opened into traffic can strike a passing bicyclist or vehicle, so you check behind you first and keep the door open no longer than necessary.
-
24. A driver leaves the vehicle at the curb where this sign is posted and walks away for two minutes. Is that allowed?
Show answer
Answer B: No, leaving the vehicle unattended there is prohibited whatever the length of the absence
Walking away leaves the vehicle parked, and the prohibition holds regardless of how long the driver is gone or whether the engine is left running.
-
25. 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.
-
26. A streetcar is coming along tracks in the middle of the street as you wait to turn across them. What should you do?
Show answer
Answer A: Let the streetcar pass before you cross the tracks
Rail vehicles cannot steer around you and need a long distance to stop, so drivers yield to a streetcar or light rail train.
-
27. 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.
-
28. Why are sign shapes and colors standardized across the whole country?
Show answer
Answer D: So a driver knows the kind of message before reading it
Uniform shapes and colors let a driver classify a sign as regulatory, warning or guide from a distance, before the legend can be read.
-
29. How should a long trip be broken up to keep the driver alert?
Show answer
Answer D: Stop for a break every couple of hours and share out the driving
Regular breaks and a change of driver are the only reliable answers to fatigue; caffeine only postpones it.
-
30. Why does a dirty windshield matter much more at night than during the day?
Show answer
Answer C: Dust and streaks scatter oncoming light and increase glare
Film and streaks on the glass spread every oncoming headlight into a star of glare, so clean the inside as well as the outside before a night trip.
-
31. A truck ahead of you is spreading salt or grit on the road. What should you do?
Show answer
Answer B: Drop back so the material does not reach your car
Spreaders throw material backward and sideways, and following close means stone chips and a screen full of spray, so leave extra distance.
-
32. You have parked but your car sits across the line into the next space. What should you do?
Show answer
Answer B: Pull out and park again fully inside one space
A car over the line takes a space away from someone else and leaves too little room for the doors of the vehicles beside it.
-
33. Where is a strong crosswind most likely to hit you suddenly?
Show answer
Answer D: Coming out of a tunnel or a cut onto an open bridge
Gusts arrive the moment you leave shelter, which is why bridge approaches and the ends of cuts and tunnels catch drivers out.
-
34. The road ahead is broken up with potholes and rough patches. What should you do?
Show answer
Answer C: Slow down, since a hole hit at speed can wreck a tire or wheel
A lower speed cuts the impact on tires, wheels and suspension and gives you time to choose a line through the rough surface.
-
35. 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.
-
36. A small plaque mounted under this sign shows a numeral such as 2 or 3. What does that numeral report?
Show answer
Answer A: How many sets of tracks the crossing carries
The plaque states the number of tracks at that location, which is a warning that a second train may be running on another track behind the first.
-
37. A pedestrian with a white cane draws the cane back and steps away from the curb as you approach. What does that usually mean?
Show answer
Answer B: They are signaling you to go ahead and drive on
Pulling the cane in and stepping back from the curb is the customary way a blind pedestrian tells drivers to proceed.
-
38. 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.
-
39. 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.
-
40. 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.
