Question 1 of 30
1. A GPS in Oregon suggests 40 mph on a residential block with no posted limit. The handbook-style default you should prefer is:
Show answer & explanation
Correct answer: C. Apps guess; Oregon's default for this kind of street is 25 mph unless a sign posts otherwise. Believe the sign first, then the state's default, then the gadget.
2. You are delivering food to a house on an unposted residential street in Oregon. Unless a sign changes it, what speed limit applies?
Show answer & explanation
Correct answer: A. Unposted residential streets in Oregon carry a default limit of 25 mph. The rule exists so drivers can stop for the unexpected, like a car backing out of a driveway. When a sign is posted, obey the sign instead.
3. A friend says every US interstate is 80 mph. In Oregon, the highest posted highway limit is actually:
Show answer & explanation
Correct answer: A. Interstate limits vary. Oregon tops out at 70 mph where posted. Learn the number for your state, then obey the sign in front of you, which is often lower.
4. How far from a stop sign or traffic signal should you stay when you park, unless signs say otherwise?
Show answer & explanation
Correct answer: B. Thirty feet from a stop sign or signal keeps the sign visible and the corner open for turning vehicles. Parking closer creates a blind box. Testers bundle this with 15 / 20 / 50 as the parking-distance set.
5. In which situations should you add extra following distance behind the vehicle ahead?
Show answer & explanation
Correct answer: C. Add following distance whenever stopping gets harder or seeing gets worse: slick roads, tailgaters behind you, big trucks blocking your view, or motorcycles that can stop quickly. More risk calls for more room ahead of you.
6. At the top of a ramp you see a square sign with a red circle and a white horizontal bar reading DO NOT ENTER. What does it mean?
Show answer & explanation
Correct answer: A. DO NOT ENTER marks a roadway where traffic flows toward you, such as an exit ramp or one-way street. Entering it risks a head-on crash. If you have already turned in and see WRONG WAY, pull over and turn around safely.
7. Setting cruise control on a rural Oregon interstate posted at the state maximum, you should set it no higher than which speed?
Show answer & explanation
Correct answer: B. The state maximum in Oregon is 70 mph, so cruise control should not be set above it where that limit is posted. Think of the posted limit as a ceiling for ideal conditions, not a required speed.
8. You are pulling out of a driveway onto a public street. What must you do?
Show answer & explanation
Correct answer: D. A driver entering a road from a driveway, alley, or private road must yield to sidewalk pedestrians and to all traffic already on the roadway. Public-road users cannot predict your exit, so the burden is on the driver emerging.
9. Do automated driver-assistance features remove your duty to watch the road, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA automated-vehicle guidance says Every vehicle currently for sale in the United States requires the full attention of the driver at all times for safe operation. Even the highest level of driving automation available to consumers requires the full engagement and undivided attention of drivers.
10. You are studying for the Oregon permit knowledge exam and want to schedule it as early as the law allows. You can hold a learner's permit beginning at which age?
Show answer & explanation
Correct answer: C. In Oregon, 15 is the earliest age for a learner's permit, so plan your knowledge exam around that date. Study the official handbook, since permit questions come from it, and arrive with the required documents ready.
11. An Oregon flashing yellow signal is showing. What should you do?
Show answer & explanation
Correct answer: A. Oregon says a flashing yellow signal means slow down and proceed with caution. A steady yellow arrow warns that the signal is about to turn red, which is a different display. Do not treat the flash as a protected turn.
12. Traffic ahead suddenly stacks up on a freeway. What is the safest speed choice?
Show answer & explanation
Correct answer: B. The posted limit is a maximum, not a target. In dense or slowing traffic you must drop to a speed that lets you stop in the space you can see. Basic speed law: do not drive faster than conditions allow.
13. What is the highest posted highway speed limit in Oregon?
Show answer & explanation
Correct answer: A. Oregon's highest posted highway limit is 70 mph. Most stretches are lower, and work zones or weather can cut it further. Do not assume every freeway in Oregon is signed at the state maximum.
14. An 18-year-old in Oregon has one beer at a graduation party and then drives. At what BAC could this driver already be violating the zero-tolerance law?
Show answer & explanation
Correct answer: C. One beer can push a young driver to any detectable amount, the level where Oregon's zero-tolerance law kicks in. The rule protects new drivers, whose crash risk rises quickly with alcohol. Skip every drink if you plan to drive.
15. A sign at an intersection shows a left-curving arrow inside a red circle with a diagonal slash. What must you do there?
Show answer & explanation
Correct answer: D. A slashed left arrow forbids left turns at that intersection, often because turning across oncoming traffic there causes crashes or blocks flow. Plan another route, such as continuing straight and circling the block. The slash cancels only the movement shown.
16. If it becomes hard to control the car, what does Ready.gov tell you to do?
Show answer & explanation
Correct answer: A. Official Ready.gov car-safety guidance says If it becomes hard to control the car, pull over, stop the car and set the parking brake. The leftover pump-the-failed-brake list is not on that page; this nearby official loss-of-control sentence is.
17. You see a red-and-white triangular sign reading YIELD as you approach a traffic circle. What should you do?
Show answer & explanation
Correct answer: B. A yield sign tells you to slow down, check for traffic with the right-of-way, and stop only when necessary to let it pass. It keeps merges smooth without forcing pointless stops. Think of yield as give way, not a full stop every time.
18. A yellow diamond shows a truck tipping on a curved arrow. What should you do before the curve?
Show answer & explanation
Correct answer: B. The tipping-truck symbol marks a curve or ramp with a recommended lower speed for high-center vehicles — and a wise lower speed for everyone. Slow before you enter the curve, not in the middle of it.
19. After two drinks at a barbecue in Oregon, you consider driving home. For a driver 21 or older, that becomes illegal starting at which BAC?
Show answer & explanation
Correct answer: A. Driving in Oregon becomes a per-se DUI at a BAC of 0.08%. Drinks affect people differently, so you cannot reliably guess your number. When you have been drinking, the smart decision is simply to skip driving.
20. You are driving at night with high beams on when a vehicle approaches from the other direction. What should you do?
Show answer & explanation
Correct answer: B. Dim to low beams for oncoming traffic so you do not blind another driver. If glare hits you, look toward the right edge of your lane to stay on course. Courtesy with light keeps everyone able to see.
21. By driving on roads in Oregon that are open to the public, what have you automatically agreed to under the implied consent law?
Show answer & explanation
Correct answer: A. Oregon's implied consent law means driving here counts as agreeing to a breath test if you are arrested for DUII. It exists so impaired drivers cannot hide the evidence. Hook: use Oregon roads, you have already said yes to the test.
22. How does the alcohol in a regular beer compare with a standard glass of wine or a single shot of liquor?
Show answer & explanation
Correct answer: B. A standard beer, glass of wine, and shot of liquor each deliver about the same alcohol, so switching drinks does not protect you. Your body counts drinks, not drink types. One is one, whatever the glass looks like.
23. An Oregon school bus has flashing red lights. A painted median or two-way left-turn lane is between you and the bus. Must you stop?
Show answer & explanation
Correct answer: A. Oregon says flashing amber lights mean the bus is about to stop, so prepare to stop. When red lights flash, stop before reaching the bus. On a divided highway with two roads separated by an unpaved median or barrier, stop only if you are on the same side. A painted median or turn lane does not create two separate roads — all lanes must stop.
24. The signal shows a green arrow for your left turn. What does having a 'protected' turn mean?
Show answer & explanation
Correct answer: B. A green arrow gives you a protected turn: conflicting traffic is held by a red signal. Still glance for people or vehicles already in the intersection, because protected means favored, not guaranteed safe.
25. An officer stops an adult driver in Oregon and a breath test is given. At what BAC reading can that driver be charged with driving under the influence, even if their driving looked steady?
Show answer & explanation
Correct answer: C. A BAC of 0.08% or more is enough by itself for a DUI charge in Oregon. The law uses a fixed number because alcohol impairs everyone, and drivers are poor judges of their own impairment behind the wheel.
26. You pass a round yellow sign marked with a large black X and the letters R R. What is it telling you?
Show answer & explanation
Correct answer: A. The round yellow RXR sign is the advance warning for a railroad crossing, posted well before the tracks. It gives you time to slow, quiet distractions, and scan for trains. Round and yellow means railroad ahead, not at, the sign.
27. What penalty does official NHTSA impaired-driving guidance say the laws should establish for failing or refusing a BAC test?
Show answer & explanation
Correct answer: A. Official NHTSA Uniform Guidelines for State Highway Safety Programs say The laws should establish effective penalties that include Administrative license suspension or revocation for failing or refusing to submit to a BAC or other drug test. The leftover implied-consent mnemonic is not on that page; this nearby official national refusal-penalty sentence is.
28. The vehicle ahead displays an orange triangle with a red border on its rear. What does that tell you?
Show answer & explanation
Correct answer: D. The orange triangle is the slow-moving vehicle emblem, common on farm equipment and horse-drawn wagons. You close in on these vehicles faster than you expect, so back off early and pass only with a clear, legal gap.
29. You are towing a small trailer on a highway posted 70 mph. What should you assume about a safe speed?
Show answer & explanation
Correct answer: B. Added weight and sway stretch your stopping distance, and some states post a lower tow limit. Even when the big number is legal, the safe number is often lower. If it sways, you are already too fast.
30. You must park on a hill where the road has no curb. Which way should you turn your wheels?
Show answer & explanation
Correct answer: A. With no curb to catch the car, always turn your wheels toward the road's edge, uphill or downhill. A runaway car then rolls off the travel lanes instead of into traffic. No curb: aim for the shoulder.
