Question 1 of 30
1. A truck ahead signals a right turn but first swings out toward the left. What should you do?
Show answer & explanation
Correct answer: C. Long vehicles swing wide to make right turns, and the tempting gap on their right closes like a trap once the trailer comes around. Hold back and wait. Do not slide into the right side of a turning truck.
2. Why is it illegal to park on a sidewalk or in a crosswalk?
Show answer & explanation
Correct answer: B. Sidewalks and crosswalks are reserved walking space; a parked car there pushes pedestrians, strollers, and wheelchairs out into traffic lanes. The law keeps walking paths continuous and safe. If people walk there, your car does not belong there.
3. At a railroad crossing you see a white X-shaped sign reading RAILROAD CROSSING, with no gates or flashing signals. How should you treat it?
Show answer & explanation
Correct answer: B. The crossbuck is a regulatory sign that legally works like a yield sign at the tracks. Trains cannot swerve or stop quickly, so you must give way every time. At passive crossings, your eyes and ears are the only warning system.
4. On a multilane highway, white lines separate the lanes. What does the white color tell you about the traffic around you?
Show answer & explanation
Correct answer: B. White lines divide lanes of traffic that flow the same way, while yellow divides opposing flows. Reading line color at a glance tells you instantly where oncoming cars can be. White means with you, yellow means toward you.
5. Signs on Oregon highways vary from road to road, but the law sets one absolute top limit for the fastest routes. That limit is which value?
Show answer & explanation
Correct answer: D. By statute, 70 mph is the fastest any Oregon road can be posted. Below that ceiling, engineers set each road's limit for its design and traffic, which is why the posted sign on your road governs.
6. BAC measures the percentage of alcohol in a person's blood. For drivers 21 and older in Oregon, what BAC puts them at or over the legal limit?
Show answer & explanation
Correct answer: C. BAC stands for blood alcohol concentration. In Oregon, adult drivers reach the illegal level at 0.08%. Remember the rule as a hard line: at 0.08% you are over, and skills like reaction time fade even sooner.
7. A 30-year-old driver in Oregon takes a chemical test after a crash. Prosecutors can prove DUI from the test result alone once the BAC is at least which value?
Show answer & explanation
Correct answer: D. A test showing 0.08% or higher proves per-se DUI in Oregon without any other evidence of impairment. Lawmakers chose that threshold because crash risk climbs sharply near it, though alcohol degrades driving skills at lower levels too.
8. You approach an Oregon school zone where the flashing yellow lights are operating. What is the fastest you may drive?
Show answer & explanation
Correct answer: B. When lights flash or children are present, Oregon school zones are capped at 20 mph. A child stepping out gives you almost no reaction time, and slower speed shrinks stopping distance. Hook: flashing lights mean twenty, no faster.
9. Your GPS routes you through a Oregon neighborhood of homes and parked cars with no posted speed limit. State law caps your speed there at what value?
Show answer & explanation
Correct answer: D. State law gives unposted residential areas in Oregon a default cap of 25 mph. Parked cars shrink your view of crossing pedestrians, which is exactly why the cap is low. Posted signs, where present, replace the default.
10. You turn off a busy road into a quiet subdivision in Oregon and see no speed limit sign on the new street. Your maximum legal speed is now which value?
Show answer & explanation
Correct answer: D. Once you enter an unposted residential street in Oregon, the limit drops to the default of 25 mph. Slow down as you turn in; the quiet look of a subdivision hides driveways, cyclists, and children near the pavement.
11. Oregon enforces 'zero tolerance' for underage drinking and driving. In practice, a driver under 21 violates this law at what BAC?
Show answer & explanation
Correct answer: A. Zero tolerance in Oregon means the under-21 line sits at any detectable amount, so even one drink can end in a suspended license. The memory hook is simple: under 21 means zero drinks before you drive.
12. You are turning left at an intersection on a green light while an oncoming car heads straight toward the intersection. What is the rule?
Show answer & explanation
Correct answer: C. A driver turning left must yield to oncoming vehicles going straight or turning right, crossing only when there is a safe gap. Straight traffic keeps its speed and path, so the turning driver waits. Left turn equals lower priority.
13. You are counting down the days until you can start driving in Oregon. The earliest age you can hold a learner's permit is which of these?
Show answer & explanation
Correct answer: D. The countdown ends at 15, the minimum learner's permit age in Oregon. Starting at the minimum is smart: more months of supervised practice before licensure means more experience with traffic, weather, and night driving while coached.
14. Which sign shape and color combination marks an interstate route?
Show answer & explanation
Correct answer: D. Interstate routes are marked by a shield split into a red band on top and a blue field below, with white numbers. Spotting the shield quickly helps you follow or avoid a freeway. Shield equals interstate.
15. The traffic signal is dark at an intersection because of a power failure. How should you treat it?
Show answer & explanation
Correct answer: A. A dark signal is treated like a stop sign in every direction so nobody assumes they have a green. Come to a full stop, then apply the usual all-way-stop order. No lights means nobody has a free pass.
16. Does the posted speed limit stay safe in bad weather, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA speeding guidance says Speed also affects your safety even when you are driving at the speed limit but too fast for road conditions, such as during bad weather, when a road is under repair, or in an area at night that isn’t well lit. The leftover hydroplane-film sentence is not on that page; this nearby official weather-speed rule is.
17. On its fastest highways, Oregon allows a top posted speed limit of which value?
Show answer & explanation
Correct answer: A. The highest speed limit in Oregon is 70 mph, and only certain highways are posted that high. Most roads carry lower limits, so drive by the signs in front of you, and slow down when conditions worsen.
18. How far from other traffic must you dim headlights in Oregon?
Show answer & explanation
Correct answer: A. Oregon says if you are using high beams you must dim when an oncoming vehicle is within 500 feet, and dim when following another vehicle within 350 feet. Headlight glare in a rearview mirror can blind the driver ahead. The 350-foot following figure is not the usual 200- or 300-foot number.
19. Which official NHTSA NDR code records a financial-responsibility failure?
Show answer & explanation
Correct answer: A. Official 23 CFR 1327 Appendix A lists D35 Failure to comply with financial responsibility law and B63 Failed to file future proof of financial responsibility. The leftover insurance-or-keys mnemonic is not on that page; this nearby official national code is.
20. You are in a left-turn lane facing oncoming traffic, and the signal shows a steady red arrow. What does the arrow mean?
Show answer & explanation
Correct answer: A. A steady red arrow prohibits the movement it points toward; you must stop and stay put until the signal changes. It shields turning drivers from crossing busy oncoming lanes. Think of a red arrow as a closed gate.
21. A pedestrian is crossing your half of the street in a crosswalk at an intersection without signals. What must you do?
Show answer & explanation
Correct answer: A. Drivers must yield to pedestrians in a crosswalk, and crosswalks legally exist at intersections even when no lines are painted. People on foot have no protection in a collision, so treat every corner as a possible crosswalk.
22. If a state legalizes marijuana possession, may you drive under the influence of the drug?
Show answer & explanation
Correct answer: A. Official NHTSA drug-impaired-driving guidance says Even in states where marijuana laws have changed, it is still illegal to drive under the influence of the drug. Driving impaired by any substance is against the law in all 50 states and the District of Columbia.
23. How does NHTSA say a lap and shoulder belt should sit?
Show answer & explanation
Correct answer: A. Official NHTSA seat-belt guidance says Place the shoulder belt across the middle of your chest and away from your neck. The lap belt rests across your hips, not your stomach. NEVER put the shoulder belt behind your back or under an arm.
24. If your car stalls on a railroad track, what does NHTSA say to do first?
Show answer & explanation
Correct answer: A. Official NHTSA railroad-crossing guidance says If your car stalls on a track, quickly get everyone out — even if you don’t see a train coming. Run away from the tracks and your car to avoid being hit by flying debris. Call the number on the blue emergency notification system sign.
25. Where are U-turns prohibited in Oregon unless a sign permits them?
Show answer & explanation
Correct answer: A. Oregon lists places where U-turns are prohibited, including intersections controlled by a traffic signal unless a sign permits the U-turn. Do not swing wide or change lanes while turning. If the signal intersection has no U-turn sign, go around the block.
26. You are driving past a school crossing just as classes let out. What must you be prepared to do?
Show answer & explanation
Correct answer: C. Near school crossings you must slow to any posted school speed and stop whenever children or crossing guards are in the crosswalk. Kids are small, quick, and unpredictable, so extra caution is required. Expect the unexpected wherever students gather.
27. You are arrested for DUII in Oregon and refuse the breath test. What should you expect?
Show answer & explanation
Correct answer: C. Refusing a breath test after a DUII arrest in Oregon triggers its own license suspension, longer than for failing, plus a fine for the refusal itself. Refusal cannot shield you. Hook: saying no punishes you twice, license and wallet.
28. A yellow diamond sign ahead shows a plus symbol, like a small cross. What is this sign warning you about?
Show answer & explanation
Correct answer: A. The crossroad symbol warns that a full intersection is ahead, so vehicles may pull out or turn from the left or right. Slow down and scan both directions. Picture the plus sign as two roads meeting.
29. A school bus on a two-lane road has stopped with red lights flashing and the stop arm out. You are coming the other way. What do you do?
Show answer & explanation
Correct answer: B. On an undivided road, both directions stop for a loading school bus. Children can run from either side. The only common exception is the far side of a divided highway with a real median. Red lights plus arm equals freeze.
30. What does official NHTSA Move Over guidance tell you to do when flashing lights are stopped on the shoulder?
Show answer & explanation
Correct answer: A. Official NHTSA Move Over guidance says All states require drivers to move over and slow down for emergency vehicles with flashing lights. Drivers approaching the vehicle should change into a lane not immediately adjacent to the vehicle, or slow down to a reasonable speed if you’re unable to safely make a lane change.
