Question 1 of 30
1. In Oregon, a driver who is 21 or older commits a per-se drunk-driving offense once their blood alcohol concentration reaches which level?
Show answer & explanation
Correct answer: B. 'Per se' means the number alone proves the offense. In Oregon, that number is 0.08%. No other proof of bad driving is needed at that level, and alcohol can still impair you below it.
2. A yellow diamond shows a bicycle and the words SHARE THE ROAD. What is it asking you to do?
Show answer & explanation
Correct answer: B. Share-the-road warnings remind you that bicyclists are legal traffic. Slow, wait for a clear gap, and pass with generous space. The sign exists because drivers otherwise squeeze bikes toward the gutter.
3. At a crosswalk signal, what is the difference between the walking-person symbol and the raised-hand symbol?
Show answer & explanation
Correct answer: C. The walking-person symbol invites pedestrians to begin crossing, while the raised hand warns them not to start; a flashing hand means finish crossing if already in the street. Drivers should expect people in the crosswalk during these phases.
4. A round yellow sign with a black X and the letters RR is posted well before a crossing. What does that advance sign tell you?
Show answer & explanation
Correct answer: A. The circular railroad advance sign gives you time to slow, scan both ways, and be ready to stop. Do not stop on the tracks. Circle plus X means rails are coming; the crossbuck at the tracks is the actual yield-to-train sign.
5. A friend in Oregon says, 'I feel fine, so I can drive.' Feelings aside, the law sets the illegal BAC for drivers 21 and older at which number?
Show answer & explanation
Correct answer: B. Feeling fine proves nothing; alcohol dulls the very judgment you use to check yourself. In Oregon, 0.08% is the per-se limit for adults, and measurable impairment often shows up well before a driver reaches it.
6. What driving does NHTSA say a learner’s permit allows?
Show answer & explanation
Correct answer: A. Official NHTSA GDL guidance says A learner’s permit allows driving only while supervised by a fully licensed driver. An intermediate license allows unsupervised driving under certain restrictions. The leftover solo-practice claim is not on that page.
7. Traffic around you on a Oregon highway posted at the state maximum starts flowing faster than the signs allow. Your personal legal limit remains which speed?
Show answer & explanation
Correct answer: C. Other drivers speeding does not raise your limit; on Oregon's fastest highways it stays 70 mph. Move right and let them pass instead of matching them. Speed limits bind each driver individually, whatever the surrounding traffic does.
8. You hit a stretch of heavy rain and patchy fog on the highway. How should you adjust your speed?
Show answer & explanation
Correct answer: B. In rain or fog, reduce speed until you could stop within the distance you can actually see, since wet pavement stretches stopping distance and fog hides hazards. Drive by sight distance: if you cannot see it, slow for it.
9. You are driving through a residential district in Oregon and see no speed limit signs. What is the default speed limit?
Show answer & explanation
Correct answer: C. Where no sign is posted, Oregon's default residential limit is 25 mph. Homes mean driveways, pets, and kids near the road, so the default stays low. A posted sign overrides the default, so watch for one.
10. What space does NHTSA tell you to give a speeding driver?
Show answer & explanation
Correct answer: A. Official NHTSA speeding guidance says Give speeding drivers plenty of space. Speeding drivers may lose control of their vehicle more easily. The leftover slow-vehicle-blocks-flow sentence is not on that page; this nearby official space rule is.
11. While planning a road trip across Oregon, you look up the fastest speed any of its highways allow. What is that statewide maximum?
Show answer & explanation
Correct answer: A. Oregon's top speed limit is 70 mph, found only on its fastest designated highways. Expect lower posted limits on most stretches, and remember signs control: the maximum applies only where a sign actually posts it.
12. You are driving on a two-lane Oregon road when an oncoming school bus stops with red lights flashing. What must you do?
Show answer & explanation
Correct answer: B. In Oregon, traffic from both directions must stop for a school bus with flashing red lights and stay stopped until the lights quit, unless the bus is on a different roadway. Children cross unpredictably. Hook: red flash, both directions stop.
13. A yellow diamond sign shows a side lane curving in to join the main road ahead. You are on the main road. What does the sign mean?
Show answer & explanation
Correct answer: C. A merge sign warns that another roadway joins yours ahead. Entering drivers must yield, but you should adjust your speed or change lanes when safe to open a gap. Merging works best when both drivers cooperate like a zipper.
14. A yellow diamond sign shows a small red stop sign symbol with an upward arrow. What should you do when you see it?
Show answer & explanation
Correct answer: C. A stop-ahead warning is used where the actual stop sign is hidden by a curve, hill, or trees. Start braking as soon as you see it, since the real stop will appear with little warning.
15. You want to park on a street just before a crosswalk. What minimum clearance do most handbooks require?
Show answer & explanation
Correct answer: B. A common handbook rule is 20 feet from a crosswalk so turning drivers and pedestrians can see each other. Parking closer hides people in the stripes. Twenty before the walk, then the hydrant's fifteen, is the pair testers expect.
16. Which official NHTSA NDR code records hit-and-run failure to stop and render aid?
Show answer & explanation
Correct answer: A. Official 23 CFR 1327 Appendix A lists B01 Hit and run—failure to stop and render aid after accident and B05 Leaving accident scene before police arrive. Crash-scene duties are still state law; this leftover uses the official national NDR label instead of inventing a uniform duty list.
17. A 19-year-old driver in Oregon says a single sip cannot matter. Under the under-21 rule, the limit is which of these?
Show answer & explanation
Correct answer: B. Oregon applies a zero-tolerance rule for drivers under 21: any detectable amount. A sip can be enough. If you are under 21, the only safe plan is no alcohol before driving.
18. How does NHTSA describe the graduated driver licensing system?
Show answer & explanation
Correct answer: A. Official NHTSA GDL guidance says GDL is a three-phase system for beginning drivers, consisting of a learner’s permit, an intermediate license, and a full license. GDL allows beginning drivers to acquire driving experience in less-risky situations and under direct supervision during the learner’s permit phase.
19. Graduated driver licensing (GDL) in Oregon moves teens through permit, intermediate, and full-license stages. Entry into the first stage, the learner's permit, begins at what age?
Show answer & explanation
Correct answer: A. GDL entry in Oregon starts with a learner's permit at 15. Each stage lifts restrictions as skill grows, because crash risk is highest in a driver's first solo months. The ladder starts at 15; climb it patiently.
20. You are driving through a busy downtown business district in Oregon with no speed signs posted. What speed does state law expect you to stay at or below?
Show answer & explanation
Correct answer: D. Where no sign is posted, Oregon law sets 20 mph as the assumed safe speed in a business district. Storefronts mean constant pedestrians, parked cars, and doors opening. Hook: downtown equals twenty, the same as a school zone.
21. What does the term "no-zone" mean when you drive near a large truck?
Show answer & explanation
Correct answer: C. No-zones are the huge blind spots in front of, behind, and beside a large truck where the driver simply cannot see you. A quick test: if you cannot see the driver's face in the truck's mirror, you are invisible.
22. Why does NHTSA tell you to slow down in snow or sleet?
Show answer & explanation
Correct answer: A. Official NHTSA winter-driving guidance says Slow down. It’s harder to control or stop your vehicle on a slick or snow-covered surface. The leftover bridges-ice-first sentence is not on that page; this nearby official slick-surface rule is.
23. You are on a through street. A driver on a driveway to your right is waiting to enter. Who must yield?
Show answer & explanation
Correct answer: B. Drivers leaving a driveway, alley, or parking lot yield to all traffic on the street, including bikes and people walking. The street already has the flow. Think: entering traffic waits; through traffic keeps moving unless a sign says otherwise.
24. Besides nighttime, when should you turn on your headlights?
Show answer & explanation
Correct answer: D. Turn on your headlights whenever conditions cut visibility, including rain, fog, snow, dusk, or dawn, because lights help other drivers spot you as much as they help you see. Handy habit: wipers on or gray sky means lights on.
25. A pedestrian in Oregon is carrying a white cane or using a guide dog. What must you do?
Show answer & explanation
Correct answer: A. Oregon says you must give the right of way to a pedestrian with limited vision, or any pedestrian who is blind or deaf-blind, carrying a white cane or using a guide dog. Yield the same way you would to other pedestrians in a crosswalk.
26. A yellow diamond sign shows a truck tilted nose-down on a black slope. You are about to descend a long, steep grade. What is the proper technique?
Show answer & explanation
Correct answer: C. On a steep downgrade, shift to a lower gear before descending so engine braking holds your speed, and use the brakes sparingly. Constant braking overheats the pads until they fade and fail. Gears save brakes; brakes alone can quit.
27. You are passing a bicyclist on a two-lane road. How much space should you leave when you can?
Show answer & explanation
Correct answer: B. A common safe-passing standard is at least three feet, and more when you are going fast or the bike is wobbling. If you cannot give the space, wait. Squeezing by is how mirrors hit handlebars.
28. What does NHTSA say happens to alcohol after it enters the bloodstream?
Show answer & explanation
Correct answer: A. Official NHTSA drunk-driving guidance says alcohol passes into the bloodstream where it accumulates until it is metabolized by the liver. The leftover coffee-or-shower sobriety claim is not on that page; this nearby official body text is.
29. During a practice drive in Oregon, your mom asks: 'No sign here, so how fast can you legally go on this residential street?' What is the correct answer?
Show answer & explanation
Correct answer: B. With no sign posted, the residential default in Oregon is 25 mph. A good habit for new drivers: entering any neighborhood, assume the default, scan for signs, and let posted limits override it whenever they appear.
30. You earned your Oregon provisional license two months ago. Which passengers under age 20 may legally ride with you?
Show answer & explanation
Correct answer: A. For the first six months with an Oregon provisional license, passengers under 20 must be immediate family. In the second six months, up to three others may ride. Teen passengers raise crash risk sharply. Hook: family first, three friends later.
