1. Every signal head at an intersection is flashing red in all directions. How should you treat the intersection?
Show answer
Answer C: As an all-way stop, stopping and then going in turn
Red flashing in every direction means each approach must stop, so the intersection works exactly like an all-way stop.
-
2. 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.
-
3. Blue pavement markings are used together with white markings at
Show answer
Answer D: parking spaces reserved for people with disabilities
Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.
-
4. 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.
-
5. Where are signs of this kind placed at an intersection?
Show answer
Answer C: At the near right and far left corners, facing drivers on the intersecting street
They are installed at the corners of the intersecting street so that a driver about to turn in sees the restriction before committing to the turn.
-
6. In a work zone, the flagger's instructions conflict with the pavement markings still visible on the road. Which do you follow?
Show answer
Answer B: The flagger, because a person directing traffic outranks the markings
An authorized flagger controlling a temporary traffic control zone overrides signs, signals and markings, and drivers must obey the flagger's signals.
-
7. You are the first to arrive at a crash on a rural road. What should you do first?
Show answer
Answer C: Park well clear of the scene, put on your hazard lights and call for help
Getting trained help on the way and keeping the scene visible does more good than anything an untrained bystander can do.
-
8. You are making a legal U-turn at an intersection. Who has the right of way?
Show answer
Answer C: Everyone else, until your turn is complete
A U-turn crosses several paths at once, so you yield to oncoming vehicles, to crossing traffic and to pedestrians before starting it.
-
9. What is sensible when you drive in an unfamiliar town for the first time?
Show answer
Answer C: Drive a little slower and give yourself more time to read the signs
In unfamiliar surroundings you need longer to take in signs, junctions and markings, and lower speed buys that time.
-
10. You come around a bend and find loose sand spread across your lane. What should you do?
Show answer
Answer D: Ease off the gas, avoid sudden braking or steering, and keep straight
Loose material acts like ball bearings under the tires; smooth inputs preserve what little grip remains, while sudden braking or steering breaks it.
-
11. You have just returned to your own lane after passing. Why should you not slow down straight away?
Show answer
Answer A: The vehicle you passed is close behind and needs room to stop
Returning and then braking leaves the driver you just overtook with almost no following distance, which is how a pass turns into a rear-end collision.
-
12. You arrive at an intersection with no signs, no signals and no markings at the same time as a vehicle on the road to your right. What must you do?
Show answer
Answer B: Yield to the vehicle on your right
At an uncontrolled intersection you must yield to a vehicle already in the intersection or approaching from your right.
-
13. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
14. A farm implement ahead of you on a two-lane road is wider than its own lane. What should you do?
Show answer
Answer D: Hang back until you can see past it and pass only with a clear road
Wide equipment hides the road ahead and may extend farther across the center line than it appears, so the pass needs more room and a much better view.
-
15. You have just passed a large truck on the freeway. Why is it dangerous to pull back in front of it and then brake for your exit?
Show answer
Answer B: A loaded truck needs much more distance to stop than a car
A fully loaded tractor-trailer can need the length of a football field or more to stop from highway speed. Cutting in and braking leaves the driver no room to avoid hitting you.
-
16. Where is this sign normally installed?
Show answer
Answer A: At an island or other obstruction in the roadway, to show which side traffic must take
It is placed at a divider, island or fixed obstruction so that drivers approaching it know without hesitating which side to pass on.
-
17. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
-
18. A school bus ahead of you has its red lights flashing and its stop arm extended. What are you required to do?
Show answer
Answer A: Stop and stay stopped until the lights stop flashing and the bus starts moving
Flashing red lights and an extended stop arm mean children are getting on or off, so traffic must stop and wait until the bus withdraws the signals and moves again.
-
19. On a wet road, how should a driver adjust after passing this sign?
Show answer
Answer B: Start braking earlier, because a slippery surface lengthens the stopping distance
A wet surface lengthens stopping distance, so the extra warning distance should be spent braking gently and early instead of late and hard.
-
20. A center lane is marked with a broken yellow line on each side and is controlled by overhead lane signals. How is that lane used?
Show answer
Answer A: It carries traffic one way or the other according to the signals
A reversible lane is marked with broken yellow lines on both sides and its direction of travel is set by the lane control signals above it.
-
21. Why is being predictable an important part of driving safely?
Show answer
Answer A: Because other road users are able to plan around what you are doing
Other drivers make their decisions from what they expect you to do, so surprises are what produce collisions.
-
22. A broken white line separates your lane from the lane on your right. What does it permit?
Show answer
Answer C: Changing lanes when it is safe to do so
A normal broken white line marks a boundary between lanes traveling the same way that road users may cross when it is safe.
-
23. A wasp flies in through the open window while you are driving. What is the safest reaction?
Show answer
Answer B: Stay calm, slow down and stop somewhere safe
Far more crashes come from the driver's reaction to an insect than from the insect, so keep your eyes forward, slow down and deal with it stopped.
-
24. What does a blood alcohol concentration of 0.08 mean for the driver of a car?
Show answer
Answer B: It is the level almost every state treats as legally intoxicated
In almost every state a driver at 0.08 or above is legally intoxicated whatever the driver seems like, but impairment starts well before that level is reached.
-
25. You have stopped on the shoulder of a highway and want to rejoin the traffic. What is the correct way?
Show answer
Answer D: Signal, build up speed along the shoulder, then merge into a gap
Entering a fast lane at a slow speed is what causes the conflict, so the shoulder is used to gain speed before the merge in the same way as an acceleration lane.
-
26. In most states, when are headlights required apart from times of poor visibility?
Show answer
Answer A: From about half an hour after sunset to half an hour before sunrise
Most states require lights from about half an hour after sunset until about half an hour before sunrise, and some simply say sunset to sunrise; lights are also required whenever visibility is poor.
-
27. You are circulating in the inner lane of a two-lane roundabout, your exit is next, and a vehicle is beside you in the outer lane. What should you do?
Show answer
Answer C: Keep circulating around the island and take that same exit on your next time around
You may not cut across a vehicle in the outer lane; if you cannot exit safely, continue around the circle and try again.
-
28. How much of a traffic lane is a motorcycle entitled to use?
Show answer
Answer D: The full width of the lane
A motorcycle is entitled to the full lane, and riders move within it to stay visible and to avoid surface hazards, so drivers should never try to share a lane with one.
-
29. Traffic ahead of you has stopped in your lane while the next lane is still moving. What is the first thing to do?
Show answer
Answer C: Slow down first and check the next lane before moving over
Braking is the action that keeps you from hitting the stopped traffic, and the lane change is only safe once you have looked.
-
30. You are starting from a stop on a snowy, icy street and the drive wheels begin to spin. What should you do?
Show answer
Answer C: Ease off the accelerator and start again more gently
Spinning tires polish the surface and dig in. Very gentle pressure on the accelerator, and a higher gear if you have one, gives the tires the best chance to grip.
-
31. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
32. You have a green left-turn arrow but a pedestrian is still walking in the crosswalk you must cross. What should you do?
Show answer
Answer B: Wait until the crosswalk is clear before turning
A green arrow protects you from other vehicles, but it never removes the duty to yield to a person already in the crosswalk.
-
33. You are passing a large truck on an open highway in a strong crosswind. What should you expect?
Show answer
Answer A: A push toward the truck, then a push the other way as you clear it
The truck shelters you as you go by and then releases you into the full gust, so the load on the steering changes twice during the pass.
-
34. You park a manual transmission car facing uphill at a curb. What is the correct combination?
Show answer
Answer A: First gear, wheels turned away from the curb, parking brake set
Facing uphill the car would roll back, so first gear resists that, the wheels turned out let a tire catch the curb, and the parking brake holds it.
-
35. An orange sign reads RIGHT LANE CLOSED AHEAD. What is the correct response?
Show answer
Answer A: Move left in good time and keep a steady pace
The sign is placed well before the taper so that drivers can merge smoothly rather than braking hard where the lane actually closes.
-
36. You pass into a work zone with a reduced speed limit but you see no workers. What speed applies?
Show answer
Answer D: The posted work zone limit, whether or not workers are present
A posted work zone speed limit is a regulatory limit in force at all times, and narrow lanes and uneven surfaces remain dangerous when nobody is working.
-
37. On a long drive you notice repeated yawning, missed exits and drifting toward the lane line. What should you do?
Show answer
Answer C: Pull off at a safe place and sleep, or change drivers
Those are warning signs that sleepiness is already interfering with driving, and only rest restores alertness. Fresh air, music and caffeine do not reverse it.
-
38. Traffic is heavy and crawling where a sign warns that your lane ends and two lanes must become one. What is the best practice?
Show answer
Answer C: Use the lane to the end, then take turns merging one by one
In stop-and-go traffic the zipper merge, using both lanes up to the merge point and then alternating, keeps the queue shorter and traffic moving; in free-flowing traffic move over as soon as it is safe.
-
39. How can you tell that a child safety seat is installed tightly enough?
Show answer
Answer C: It moves less than an inch side to side or front to back at the belt path
A correctly installed seat is nearly immovable where the belt or lower anchors pass through it. Excess movement lets the child's body travel farther in a crash.
-
40. Under Washington's open container law, where may a driver lawfully store an alcoholic beverage that has already been opened?
Show answer
Answer B: In the trunk of the vehicle
Washington law treats the glove compartment as part of the area occupied by driver and passengers, so an opened container must instead go in the trunk or a similarly separate area.
