Question 1 of 30
1. A fluorescent pink diamond is posted after a storm, showing a landslide symbol. What does the unusual color mean?
Show answer & explanation
Correct answer: B. Fluorescent pink is the MUTCD color for incident and emergency management, used for crashes, floods, or slides. Slow down and expect workers, debris, or a sudden close. Pink means something urgent just happened.
2. An officer in Oklahoma stops a driver who is 18. A test shows a very small amount of alcohol. The under-21 threshold that can trigger a violation is:
Show answer & explanation
Correct answer: C. Under-21 drivers in Oklahoma are not judged by the adult 0.08%-style line. The threshold is any detectable amount. That is why testers keep asking the youth number separately from the adult number.
3. Which state agency issues learner permits and driver licenses in Oklahoma?
Show answer & explanation
Correct answer: D. Service Oklahoma is the state agency that issues Oklahoma driver licenses, learner permits, and ID cards, both online and at its licensing offices. When you need anything license-related, oklahoma.gov/service is the front door. The name says the job.
4. You are on an entrance ramp about to merge onto a freeway. Who is responsible for yielding?
Show answer & explanation
Correct answer: A. Drivers merging onto a freeway must yield to traffic already on it, using the ramp to match speed and slide into a gap. Through traffic cannot stop safely at highway speeds, so the entering driver adapts.
5. You are driving on a road with few traffic lights when you see a yellow diamond sign showing a traffic signal symbol. Why is this sign posted, and how should you respond?
Show answer & explanation
Correct answer: B. Signal-ahead warnings are posted where a traffic light may surprise drivers, such as after a long stretch without one or where a hill blocks the view. Ease off the gas early so a sudden red light cannot catch you.
6. Unless a local sign posts a different number, how far must you stay from a fire hydrant when you park?
Show answer & explanation
Correct answer: B. Most state handbooks use a 15-foot keep-clear zone at hydrants so firefighters can hook up hoses without moving cars. Fifteen is the number social-study threads keep missing. If you can touch the hydrant from the door, you are too close.
7. A diamond-shaped orange sign with black markings is posted ahead of a lane shift. What class of message is that?
Show answer & explanation
Correct answer: B. Orange diamonds are reserved for temporary traffic-control in work zones. They warn that the road, lanes, or workers ahead are not in their usual place. When the background turns orange, expect cones, narrowed lanes, and people on foot.
8. An officer stops an adult driver in Oklahoma 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 Oklahoma. The law uses a fixed number because alcohol impairs everyone, and drivers are poor judges of their own impairment behind the wheel.
9. 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.
10. May you park in an Oklahoma intersection?
Show answer & explanation
Correct answer: A. Oklahoma’s numbered parking bans include a public or private driveway, within an intersection, within 15 feet of a hydrant, and on a crosswalk. An intersection is a travel space, not a loading zone.
11. You are studying for the Oklahoma 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 Oklahoma, 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.
12. Until what age does NHTSA say to keep a child in the back seat?
Show answer & explanation
Correct answer: A. Official NHTSA car-seat guidance says Keep your child in the back seat at least through age 12. All children under 13 ride in the back seat for maximum safety. Rear-facing is required under age 1.
13. 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.
14. An Oklahoma flashing yellow arrow is showing for a left turn. What must you do?
Show answer & explanation
Correct answer: A. Oklahoma’s signal chapter says a flashing yellow arrow for a left turn means reduce speed and proceed with the left turn only after yielding to oncoming traffic and pedestrians. Oncoming traffic has the right-of-way. It is not a protected green arrow.
15. 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.
16. 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.
17. An ice-cream truck is stopped ahead and children are gathered around it. How should you drive past?
Show answer & explanation
Correct answer: C. Slow way down and cover your brake near children or a stopped ice-cream truck, because kids chase treats and forget traffic completely. Expect someone small to dart out. Around children, drive as if one already has.
18. An Oklahoma steady yellow light is showing. What does the manual say it means?
Show answer & explanation
Correct answer: A. Oklahoma’s steady yellow is a warning that the light is about to turn red. Come to a smooth stop if needed. Do not speed up to beat the light. Enter carefully only if you are already too close to stop safely.
19. In Oklahoma, a driver who is 21 or older breaks the law by driving with a blood alcohol concentration (BAC) at or above what level?
Show answer & explanation
Correct answer: A. Oklahoma law makes it illegal to drive with a BAC of 0.08% or higher. Alcohol slows judgment and reaction time, and impairment can begin well below that number. Treat 0.08% as a legal line, not a safe target.
20. A yellow diamond sign shows a car with wavy skid marks trailing behind its tires. When does this warning matter most?
Show answer & explanation
Correct answer: D. The skidding-car sign warns that the road ahead becomes slippery when wet, so slow down and avoid sudden braking or sharp steering in rain, snow, or ice. The first minutes of rain are often the slickest, as water lifts oil off the pavement.
21. What does a posted speed limit actually tell you?
Show answer & explanation
Correct answer: A. A posted limit is the top legal speed when conditions are ideal: dry pavement, good visibility, light traffic. In worse conditions, a safe speed is lower. Treat the number as a ceiling to stay under, not a target to hit.
22. If your vehicle catches fire, what first steps does the U.S. Fire Administration list?
Show answer & explanation
Correct answer: A. Official USFA vehicle-fire guidance says Pull over as quickly as you can when it is safe. Once you have stopped, turn off the engine. Get everyone out of the vehicle. Never return to a burning vehicle. Move everyone at least 100 feet from the burning vehicle and well away from traffic. Call 911.
23. A classmate insists everyone must wait until 18 to start driving in Oklahoma. The real minimum age for a learner's permit is which of these?
Show answer & explanation
Correct answer: D. Your classmate is wrong: Oklahoma grants learner's permits at 15. Starting earlier gives you months of supervised practice while risk is lowest. When rules feel fuzzy, confirm them in the official state driver handbook.
24. What is the safest way to handle your speed through a sharp curve?
Show answer & explanation
Correct answer: B. Slow to a safe speed before the curve begins, then hold steady or gently accelerate through it. Braking mid-curve can break tire grip and cause a skid. Do your slowing on the straightaway, your steering in the bend.
25. What is the highest posted highway speed you should expect to see in Oklahoma?
Show answer & explanation
Correct answer: C. Oklahoma's top posted highway limit is 80 mph. Most roads are lower. Do not treat the state maximum as the speed for every freeway ramp or work zone.
26. In Oklahoma, an under-21 driver can face a license suspension for alcohol at a much lower level than an adult DUI. That zero-tolerance level is which of these?
Show answer & explanation
Correct answer: D. Reaching any detectable amount can cost a driver under 21 their license in Oklahoma, even when they show no obvious impairment. The state treats underage drinking and driving as a license issue first, aiming to stop the habit early.
27. A passenger claims some Oklahoma highways have unlimited speed like the German autobahn. In reality, the state's highest legal limit is which of these?
Show answer & explanation
Correct answer: D. Every road in Oklahoma has a limit, and the statewide ceiling is 80 mph on designated highways. Higher speeds multiply crash energy dramatically, so no US state allows unlimited speed. Follow whatever limit is actually posted.
28. Which official NHTSA NDR code records driving with an expired or missing license?
Show answer & explanation
Correct answer: A. Official 23 CFR 1327 Appendix A lists B51 Expired or no driver license (includes DL, CDL, and Instruction Permit). The leftover impound-and-delay sentence is state sanction wording; this nearby official national code is.
29. Headlights are required from sunset to sunrise. When else should you turn them on?
Show answer & explanation
Correct answer: B. Wipers on, lights on is the rule many states write down and testers repeat. Lights help others see you as much as they help you see. If the sky is gray or the glass is wet, flip them on.
30. While you wait to turn, the green arrow changes to a steady yellow arrow. What is the signal telling you?
Show answer & explanation
Correct answer: D. A steady yellow arrow warns that the protected turning phase is about to end. Stop if you can do so safely; drivers already at the point of no return may finish the turn cautiously. Yellow arrow means wrap up, not speed up.
