1. A preferential lane sign reads HOV 2+ and lists the hours it applies. During those hours, which vehicles may use the lane?
Show answer
Answer A: Vehicles carrying at least two people, counting the driver
The number on an HOV sign is the minimum number of occupants, driver included, that a vehicle must carry to use the lane while the restriction is in effect.

2. How long after a provisional license is first issued does Oregon's midnight-to-5-a.m. driving restriction apply, assuming the holder has not yet turned 18?
Show answer
Answer A: For the first year after the license is issued
ORS 807.122 applies the midnight-to-5-a.m. driving restriction for the first year after a provisional license is issued, unless the holder turns 18 sooner.
-
3. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
4. You brake hard in a vehicle with antilock brakes and feel the pedal pulsing under your foot. What should you do?
Show answer
Answer A: Keep firm, steady pressure on the pedal and steer where you need to go
The pulsing is the system releasing and reapplying the brakes so the wheels keep rolling, which is what lets you steer while braking. Pumping the pedal defeats it.
-
5. May you park in front of a public or private driveway?
Show answer
Answer A: No, blocking a driveway is prohibited even for a short time
Parking in front of a driveway blocks the property owner from entering or leaving, and the prohibition does not depend on how long you stay.
-
6. You have strapped luggage to the roof rack for a long trip. What should you expect?
Show answer
Answer D: A higher center of gravity, so take the curves and lane changes gently
Weight on the roof raises the center of gravity and makes the vehicle lean and respond more slowly to steering.
-
7. 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.
-
8. A turn restriction sign at the corner shows a range of times below the symbol. What does that mean?
Show answer
Answer A: The turn is banned only during the hours shown on the sign
Times posted under a regulatory symbol set the period during which the restriction applies; outside those hours the movement is permitted.
-
9. You come up behind a group of cyclists riding two abreast on a narrow rural road. What should you do?
Show answer
Answer A: Wait for a clear stretch and pass them as one group
Passing a group as a single unit when the way ahead is clear is safer than several rushed passes, and cutting through the group leaves nobody any escape room.
-
10. The only person offering you a ride home has been drinking. What should you do?
Show answer
Answer B: Do not get in; find another way home
A passenger in an impaired driver's vehicle shares all of the risk and can do nothing about it from the seat, so the only safe answer is another ride.
-
11. At an intersection where turning on a red arrow is not permitted, the signal shows a red left arrow next to a steady green ball. What may you do?
Show answer
Answer D: Go straight or turn right if permitted, but not left
An arrow controls only the movement it points to, so here the red arrow stops the left turn while the green ball still allows the other movements.
-
12. Red pavement markings are used on a roadway to show that
Show answer
Answer A: it must not be entered from that direction
Red markings identify a roadway that is not to be entered or used, and they also mark the pavement of truck escape ramps.
-
13. 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.
-
14. What does it mean to scan the road while driving?
Show answer
Answer A: Moving your eyes constantly over the road, the sides and the mirrors
Scanning keeps information coming in from every direction, while a fixed stare leaves you blind to everything else.
-
15. 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.
-
16. Under Oregon law, exceeding a posted speed limit by 21 to 30 miles per hour is punishable as which class of traffic violation?
Show answer
Answer B: Class B traffic violation
ORS 811.109 classifies speeding 21 to 30 mph over the posted limit as a Class B traffic violation, one step below the top Class A tier reserved for more than 30 mph over.
-
17. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
-
18. You are about to pass a large truck on a two-lane highway. Which practice is correct?
Show answer
Answer A: Finish the pass without delay and expect wind turbulence beside the truck
Lingering beside a truck keeps you in its blind spot and exposes you to air turbulence. Pass on the left, keep moving, and move back only when you can see the whole truck in your mirror.
-
19. Your vehicle has stalled on railroad tracks and no train is in sight. After getting everyone away, whom should you call first?
Show answer
Answer B: The railroad emergency number posted on the blue sign at the crossing, giving the crossing number
Every public crossing has a blue emergency notification sign with a phone number and a crossing identification number. That call lets the railroad stop or slow trains before they reach you.
-
20. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
21. You enter a corner faster than the turn can be taken. What is the most likely result?
Show answer
Answer A: The vehicle runs wide and may cross into another lane
Excess speed uses up the available grip, so the vehicle follows a wider arc than intended and drifts out of its lane.
-
22. 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.
-
23. You see smoke coming from under the hood while driving. What should you do?
Show answer
Answer D: Signal, pull well off the road, shut off the engine and move everyone away from the vehicle
Stopping and shutting off the engine cuts the fuel supply to a possible fire, and distance protects you if it spreads. Raising the hood can feed the fire a rush of air.
-
24. How often should you check your mirrors while driving?
Show answer
Answer C: Every few seconds, so you always know what is around you
Traffic behind and beside you changes constantly. Frequent, brief mirror checks keep a picture of your surroundings current so nothing surprises you.
-
25. A power line has fallen across your vehicle after a crash. What should you do?
Show answer
Answer C: Stay inside and wait for utility workers unless fire forces you out
The vehicle body may be energized, and touching it and the ground at the same time can be fatal. If you must leave because of fire, jump clear with both feet together and shuffle away.
-
26. A yellow diamond shows a horse with a rider. Besides slowing down, what else should a driver do?
Show answer
Answer C: Avoid using the horn or revving the engine
The equestrian crossing sign warns of horses on or across the road, and a sudden noise can startle an animal into the traffic lane.
-
27. Why does a heavier vehicle need more room to stop than a light one from the same speed?
Show answer
Answer B: Because there is more mass in motion for the tires to slow down
More mass means more energy at the same speed, and the brakes and tires need more distance to get rid of it.
-
28. How should you follow a school bus in traffic?
Show answer
Answer A: Far enough back to see its lights and stop in time
A school bus stops often and with little warning, so a longer following distance gives you time to see the lights come on and stop clear of it.
-
29. How do stimulant drugs such as amphetamines or cocaine typically affect driving?
Show answer
Answer D: They can make the driver overconfident and more willing to take risks
Stimulants create a false sense of alertness and encourage aggressive, risky driving. When they wear off, sudden fatigue can follow.
-
30. You face a red light at an intersection that has no stop line and no marked crosswalk. Where must you stop?
Show answer
Answer C: Before entering the intersection
With no line and no crosswalk, the stopping point is the near edge of the intersecting roadway, close enough to see cross traffic but clear of it.
-
31. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
32. Traffic in a work zone is down to one lane in each direction, separated by a temporary double yellow line. May you pass?
Show answer
Answer C: No, temporary markings prohibit passing just as permanent ones do
A temporary marking has the same legal force as a permanent one, and a work zone is the last place with room to spare for an overtaking vehicle.
-
33. An arrow panel in a work zone shows four flashing lamps in caution mode instead of an arrow. What does that display mean?
Show answer
Answer A: Warning only, so pass the work area with caution in your current lane
Caution mode gives a general warning without directing a lane change, so drivers stay alert and pass the activity with care.
-
34. May you exceed the posted speed limit in order to complete a pass?
Show answer
Answer C: No, the posted limit applies while you are passing too
The limit does not lift for passing; if you cannot complete the pass within it, there is not enough room and you should stay back.
-
35. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
