1. A wide solid white line separates the through lanes from an exit lane. What does it tell drivers?
Show answer
Answer B: The choice of lane should already have been made
A channelizing line marks where the paths separate and crossing it is discouraged or prohibited, so the lane change has to happen upstream.
-
2. A sign at the intersection prohibits U-turns, but the opening looks wide and clear. What may you do?
Show answer
Answer B: Obey the sign and turn around somewhere else
A prohibition applies whatever the traffic looks like at that moment, usually because of sight distance or conflicts you cannot see from the lane.
-
3. Does Oregon's bicycle stop-as-yield law let a cyclist treat a steady, non-flashing red traffic light the same as a stop sign?
Show answer
Answer A: No, the stop-as-yield treatment only covers stop signs and flashing red signals, not a steady red light
ORS 814.414 and ORS 814.416 extend the stop-as-yield treatment only to stop signs and flashing red signals; a bicycle rider must still come to a complete stop and wait for a steady red traffic light to change.
-
4. How do worn tires and worn brakes affect your ability to stop?
Show answer
Answer C: They lengthen the stopping distance, especially on a wet road
Worn tread cannot clear water and worn brakes cannot produce full force, so both stretch the distance needed to stop.
-
5. Your green left-turn arrow goes out and a steady green ball stays lit. What may you do?
Show answer
Answer A: Continue turning left, but only after yielding to oncoming traffic
When the arrow ends and a green ball remains, the turn changes from protected to permissive, so it is still allowed but oncoming traffic goes first.
-
6. The traffic signal is green, but the crossing lights on the tracks inside the intersection begin to flash. What must you do?
Show answer
Answer C: Stop clear of the tracks and wait, even though the signal is green
Active crossing warning devices outrank the green indication, so you stop short of the rails and wait until the warning stops.
-
7. 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.
-
8. In which crash must the police always be notified?
Show answer
Answer D: Any crash in which somebody has been injured or killed, whatever the damage
Injury or death always makes a crash reportable, whatever the amount of vehicle damage or the opinions of the drivers.
-
9. How should a head restraint be adjusted?
Show answer
Answer D: So the top is at least as high as the back of your head and close behind it
A restraint set at head height and close behind limits how far the head snaps backward in a rear impact, which is what reduces neck injury.
-
10. A law enforcement officer is directing traffic and waves you forward while the signal facing you shows red. What should you do?
Show answer
Answer A: Follow the officer's direction and proceed
Directions given by an officer controlling traffic take priority over signals, signs and pavement markings.
-
11. 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.
-
12. An overhead lane-use control signal shows a steady red X above the lane you are traveling in. What does it require?
Show answer
Answer D: Leave that lane, because it is closed to you
A steady red X means road users are not permitted to use the lane beneath it, so you must move into a lane that is open.
-
13. Which color scheme is standard for the drums and barricades that channel traffic through a work zone?
Show answer
Answer C: Alternating orange and white retroreflective stripes
Drums and barricades carry alternating orange and white retroreflective stripes, and the traffic cones used in the same zones are predominantly orange.
-
14. Does this sign settle who has the right-of-way at the intersection ahead?
Show answer
Answer D: No, it only gives notice of the intersection; the control there decides priority
A warning prepares the driver for what is coming but grants no priority, so whatever stop control, yield control, signal or right-of-way rule applies at the intersection is what decides.
-
15. The lane you are in has a right-turn-only arrow painted on the pavement. What must you do?
Show answer
Answer C: Turn right, because a lane-use arrow is a legal requirement
Lane-use arrows painted on the pavement are regulatory markings, so a driver in that lane must travel in the direction shown.
-
16. The divided highway ends warning sign means that
Show answer
Answer D: the median separating the directions ends and the road returns to two-way operation
Beyond this sign opposing traffic is no longer separated by a median, so the driver must keep right and expect vehicles approaching in the adjacent lane.
-
17. A signal stands part way up a freeway entrance ramp and turns green briefly again and again. How many vehicles does such a signal normally release on each green?
Show answer
Answer A: One for each lane of the ramp
A ramp control signal releases a single vehicle per lane on each green so that vehicles reach the merge one at a time instead of in a bunch.
-
18. Compared with dry pavement, how much room does a vehicle need to stop on packed snow?
Show answer
Answer D: Several times as much
Grip on packed snow is a fraction of that on dry pavement, so stopping distance grows several times over. Antilock brakes help you steer, not stop shorter.
-
19. A black on white regulatory sign at an intersection reads NO TURNS. What may a driver do there?
Show answer
Answer B: Only continue straight through the intersection
The NO TURNS sign bans turns in every direction at that intersection, so the only lawful movement from that approach is straight through.
-
20. 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.
-
21. In Oregon, careless driving is normally a Class B traffic violation. What happens to its classification if the careless driving contributes to a crash?
Show answer
Answer D: It becomes a Class A traffic violation, the most serious traffic violation tier
ORS 811.135 upgrades careless driving from a Class B to a Class A traffic violation when the offense contributes to an accident.
-
22. Why is it often safer to back into a parking space than to back out of one?
Show answer
Answer D: Because you leave the space going forward, with a clear view
Backing into the space puts the difficult maneuver where you are stopped and looking around, and lets you drive out facing the traffic and pedestrians.
-
23. Your light turns green, but a vehicle from the cross street is still finishing a turn inside the intersection. What should you do?
Show answer
Answer B: Wait until that vehicle has cleared the intersection
A green indication lets you proceed only after yielding to pedestrians in the crosswalk and to vehicles already lawfully within the intersection.
-
24. Driving at night you notice that the raised markers along the line beside you are throwing back red light. What does that tell you?
Show answer
Answer C: You are facing traffic and must get off that roadway
Red retroreflection is shown only toward traffic that should not be there, so a red return means the vehicle is heading the wrong way.
-
25. 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.
-
26. Alcohol is classified as which kind of drug?
Show answer
Answer B: A depressant that slows the central nervous system
As a depressant, alcohol slows the brain and nervous system, which lengthens reaction time and dulls the coordination that driving depends on.
-
27. Why is backing up on a freeway or on its shoulder prohibited?
Show answer
Answer A: Traffic arrives far too fast to expect a vehicle moving the wrong way
Freeway traffic closes on a stopped or reversing vehicle at highway speed and has almost no time to react to something moving against the flow.
-
28. What is the correct technique for backing a vehicle straight?
Show answer
Answer B: Check behind the vehicle before getting in, then turn and look through the rear window while backing slowly
Mirrors and cameras leave gaps close to the vehicle, so walk behind it first, then turn in your seat for a direct view and keep the speed low enough to stop instantly.
-
29. Which surfaces usually offer less grip than the pavement around them when wet?
Show answer
Answer B: Painted markings, metal plates and bridge decks
Paint, steel and bridge decks all shed grip when wet or cold, so brake before you reach them rather than on top of them.
-
30. 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.
-
31. 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.
-
32. You are turning left at an intersection just beyond the crest of a hill. What is the added risk?
Show answer
Answer B: Oncoming vehicles appear with very little warning and close quickly
A crest hides approaching traffic until it is close, so the gap you thought was empty can fill in the time the turn takes.
-
33. You have just driven through a deep puddle and your brakes feel weak. What should you do?
Show answer
Answer D: Drive slowly while lightly applying the brakes until they dry and work normally
Wet brakes grip poorly and may pull to one side. Gentle braking at low speed generates heat that dries the pads and discs quickly.
-
34. How does alcohol affect a driver's ability to handle several things at once?
Show answer
Answer B: It cuts the ability to divide attention between tasks
Driving means watching the road, the mirrors and the instruments together, and alcohol narrows attention so that one of those tasks is dropped without the driver noticing.
-
35. What night driving restriction applies to an Oregon driver under 18?
Show answer
Answer B: No driving between midnight and 5:00 a.m. without a listed exception
An Oregon driver under 18 may not drive between midnight and 5:00 a.m. unless traveling to or from work or a school event, or accompanied by a licensed driver at least 25 years old.
