1. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
2. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
3. You signaled a lane change and the signal did not switch itself off afterwards. Why does that matter?
Show answer
Answer B: Other drivers may act on a turn you do not intend to make
A signal left on tells other drivers you are about to turn, and someone may pull out in front of you. Cancel it as soon as the maneuver is finished.
-
4. Absent any other posted limit, what speed does Washington law set as the maximum on county roads?
Show answer
Answer B: 50 miles per hour
Washington's basic speed statute sets 50 miles per hour as the default maximum on county roads when no other limit is posted.
-
5. Your vehicle is burning at the roadside. How far away should everyone keep?
Show answer
Answer D: At least a hundred feet away from the vehicle and upwind, out of the drifting smoke
Burning vehicles give off toxic smoke and parts such as tires and struts can burst, so keep a long distance and stay upwind.
-
6. At what tread depth should a tire be replaced?
Show answer
Answer A: When the tread is worn down to 2/32 of an inch
At that depth a tire loses grip quickly, especially on wet roads, and the built in wear bars or the penny test both show when the point has been reached.
-
7. At what active THC concentration does Washington treat a driver aged 21 or older as driving under the influence?
Show answer
Answer C: More than 5 nanograms per milliliter of blood
Washington treats more than 5 nanograms of active THC per milliliter of blood as a DUI for drivers aged 21 and older, while any amount above zero applies to drivers under 21.
-
8. Your right wheels drop off the edge of the pavement onto a soft shoulder. What should you do?
Show answer
Answer C: Ease off the accelerator, hold the wheel straight and steer back gently once you have slowed
Yanking the wheel while the tires are pressed against a pavement lip can throw the vehicle across the road, so slow down first and then make a gentle correction.
-
9. You are traveling at the same speed as a vehicle in the next lane, just behind its rear door. What should you do?
Show answer
Answer B: Change your speed so that you leave that driver's blind spot
That position is the classic blind spot. Slow slightly or move ahead so the other driver can see you before deciding to change lanes.
-
10. 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.
-
11. A sign warns that your exit leaves from the left side of the freeway. What should you do?
Show answer
Answer D: Move into the left lane in good time before you reach the exit
Left-hand exits are unusual, which is exactly why they are signed well in advance and why the lane changes should be finished early.
-
12. Your vehicle has broken down at night on a rural road and your phone has no signal. What is the safest thing to do?
Show answer
Answer C: Stay with the vehicle, keep the hazard lights on and wait for help
A lit vehicle is far easier to find than a person walking in the dark, and running the engine while you sleep risks carbon monoxide.
-
13. You pull onto a soft grass verge to park. What is the main risk?
Show answer
Answer A: The wheels can sink and the car can slide toward the ditch
Soft ground gives way under the weight of a vehicle, and a car that settles or slides sideways can end up stuck or in the ditch.
-
14. A school sign paired with a plaque showing a diagonal downward-pointing arrow is installed
Show answer
Answer D: at the school crossing itself, or as close to it as possible
The diagonal downward arrow points at the crossing, so this assembly is placed at the crossing location rather than in advance of it.
-
15. You are about to pass a long tractor-trailer on a two-lane road. What should you expect?
Show answer
Answer B: You will need more clear road, since the vehicle is much longer
A tractor-trailer can be 70 feet long, so passing it takes more distance and more time than passing a car at the same speed difference.
-
16. What should a driver do first after passing this sign?
Show answer
Answer A: Move into the right-hand lane and stay there
Traffic returns to two-way operation, so the driver keeps to the right of the centerline and stops treating the left side as available.
-
17. Your engine stalls while you are driving in traffic. What is the correct response?
Show answer
Answer A: Shift to neutral, try to restart it, and steer and brake toward the side of the road
With the engine off, power steering and power brake assistance fade, so steering and braking take more effort but still work. Neutral lets you attempt a restart while you coast to safety.
-
18. How should you handle a prescription or over the counter medicine before driving?
Show answer
Answer D: Read the label and ask a pharmacist or doctor whether it affects driving
Many common medicines, including allergy and cold remedies, cause drowsiness or slowed reactions, and the label or a pharmacist can tell you whether driving is safe.
-
19. A lane is marked with a large white bicycle symbol and chevrons, but there is no separate bicycle lane. What does it mean?
Show answer
Answer A: Bicyclists may use the whole lane, so follow or pass with care
A shared lane marking shows that bicyclists and drivers use the same lane and positions riders away from parked car doors, so passing means changing lanes.
-
20. 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.
-
21. After a crash, what information should you exchange with the other driver?
Show answer
Answer B: Name, address, driver license, vehicle registration and insurance details
Identification, registration and insurance information are what the other party and the insurers need. Sensitive financial details are never required.
-
22. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
23. Can a Washington court waive, reduce or suspend the fine for a move-over law violation?
Show answer
Answer D: No, the fine may not be waived, reduced or suspended
Washington law prohibits waiving, reducing or suspending the fine for a move-over law violation.
-
24. How does braking distance change if you double your speed?
Show answer
Answer D: It grows much more than twice as long
Braking distance increases with the square of speed, so doubling speed roughly quadruples the distance needed to stop.
-
25. Do hazard lights make it legal to leave your vehicle in a no parking zone?
Show answer
Answer A: No, they warn other drivers but do not permit the parking
Hazard lights are a warning device, not a permit; the parking restriction applies whether they are flashing or not.
-
26. You are approaching a refuse collection truck working along your street. What should you expect?
Show answer
Answer D: Workers stepping into the road around the truck
Collection crews move constantly between the truck and the curb, often from where you cannot see them, so slow right down and pass only when the whole area is clear.
-
27. You are pulling out of a farm entrance onto a rural highway. What is your obligation?
Show answer
Answer C: Yield to every vehicle already on the highway before you enter the roadway
A driver entering a highway from a private road or driveway yields to every vehicle already on the highway.
-
28. You come up behind a bicyclist who is descending a steep hill in the middle of the traffic lane. What should you take into account?
Show answer
Answer D: The rider may be moving at close to the speed of the traffic
A bicycle can reach the speed of traffic on a descent, so there is little to gain from a pass and the rider needs the whole lane to steer around surface hazards.
-
29. A sign at the signal reads LEFT TURN ON GREEN ARROW ONLY. The ball turns green but no arrow appears. What may you do?
Show answer
Answer C: Wait, because your turn is allowed only while the arrow is showing
The sign removes the permissive turn, so the left is legal only during the green arrow and you must wait behind the line until it appears.
-
30. Once a driver has joined the route this sign begins, how is the rest of the way marked?
Show answer
Answer B: By further markers of the same kind at each turn, until the original road is rejoined
The alternate route is signed continuously, with a marker at every turn, so a driver with no local knowledge can follow it back to the original road.
-
31. A driver is thinking about overtaking a slower vehicle and sees this sign a short distance ahead. What does it mean for that pass?
Show answer
Answer B: The pass must be finished before the restricted section begins
The sign marks the start of a section where passing is prohibited, so a driver may not be on the left side of the road beyond it; any pass has to be completed before that point or not started at all.
-
32. Why do many crashes happen on routes the driver knows very well?
Show answer
Answer D: Familiar roads let attention slip into routine
When a route is automatic the mind wanders and hazards get missed, which is why a well known road deserves the same attention as a strange one.
-
33. How far in advance of expiration can a Washington driver begin the license renewal process?
Show answer
Answer B: One year before expiration
Washington allows a driver to begin renewing a license up to one year before it expires.
-
34. What condition does this sign warn a driver about?
Show answer
Answer B: Another road joins the road being traveled, from one side
It announces a side road entering the main roadway, so the driver should expect vehicles waiting to pull out and other vehicles slowing to turn in.
-
35. How far before and after a qualifying stationary vehicle does Washington's move-over law define the protected zone?
Show answer
Answer C: 200 feet
Washington's move-over law defines the protected emergency or work zone as the adjacent lanes 200 feet before and after the qualifying vehicle.
-
36. Once you are moving, which way of using a navigation device costs you the least attention?
Show answer
Answer B: Listening to the spoken directions
Voice guidance lets you keep your eyes on the road, while anything that needs the screen takes glances that add up over a trip.
-
37. A small yellow plaque showing a speed number below a curve warning sign gives
Show answer
Answer C: the speed recommended for the condition being warned about
The advisory speed plaque belongs to the warning series and states the speed judged safe for the condition ahead under good circumstances, not a regulatory limit.
-
38. You are clear of the tracks after your vehicle stalled on a crossing. Whom should you contact?
Show answer
Answer C: The emergency number posted on the blue sign at the crossing, or 911
Grade crossings carry an emergency notification sign with a railroad phone number and a crossing identification number so that approaching trains can be stopped, and 911 works if that sign is not visible.
-
39. Where is a U-turn generally the most reasonable choice?
Show answer
Answer B: At an intersection where it is permitted and you can see well both ways
A U-turn needs a legal place and a long clear view in both directions, which is why a permitted intersection with open sight lines is the usual choice.
-
40. Why do bridges and overpasses deserve extra caution when temperatures are near freezing?
Show answer
Answer A: They lose heat from above and below, so they ice over before the surrounding road
A bridge deck is exposed to cold air on both surfaces and has no ground beneath it to hold heat, so ice can form there while the connecting road is still only wet.
