Question 1 of 30
1. 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.
2. A wide white bar is painted across your lane just before an intersection with a stop sign. Where must you stop?
Show answer & explanation
Correct answer: D. A stop line marks the exact place to stop: bring your vehicle to a halt before the bar, not on or past it. It keeps you clear of crosswalks and cross traffic. The bar is the boundary.
3. You are comparing Oklahoma with a neighboring state that uses 0.08%. For an adult driver in Oklahoma, driving is a per-se offense at which BAC?
Show answer & explanation
Correct answer: A. Do not assume every state still uses the same adult number. In Oklahoma the per-se line is 0.08%. Utah famously uses 0.05%; most others use 0.08%. Learn your own state's figure.
4. What does NHTSA say about over-the-counter and prescription drugs and driving?
Show answer & explanation
Correct answer: A. Official NHTSA drug-impaired-driving guidance says Some prescription and over-the-counter medicines can cause extreme drowsiness, dizziness, and other side effects. Warnings against operating heavy machinery include driving a vehicle.
5. 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.
6. A 19-year-old driver in Oklahoma says a single sip cannot matter. Under the under-21 rule, the limit is which of these?
Show answer & explanation
Correct answer: B. Oklahoma 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.
7. You are driving in a lane with a large white arrow painted on the pavement curving to the right. What does this marking require?
Show answer & explanation
Correct answer: B. A curved lane-use arrow makes that lane turn-only: follow the arrow or change lanes before the intersection. The arrows sort traffic early so drivers do not swerve at the last second. The pavement is telling you your path.
8. 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.
9. A freeway on-ramp has a recommended speed of 35 mph on a yellow plaque. The freeway is posted 65. What should you do on the ramp curve?
Show answer & explanation
Correct answer: B. Yellow advisory speeds mark ramps and curves that cannot be taken at the highway limit. Slow for the curve, then speed up in the acceleration lane. Advisory plaques are the voice of physics, not decoration.
10. A solid white line, instead of a broken one, separates your lane from the next lane going the same way. What is it telling you?
Show answer & explanation
Correct answer: A. A solid white line between same-direction lanes discourages lane changes, and it appears where drifting is risky, such as near intersections and ramps. The firmer the line looks, the firmer the message: hold your lane.
11. At a BAC of .02, what typical effect does NHTSA list first?
Show answer & explanation
Correct answer: A. Official NHTSA drunk-driving guidance says .02 Some loss of judgment; relaxation, slight body warmth, altered mood. Testers invent leftover first-skill folklore. Learn that official wording, then answer the knowledge test from those words.
12. Graduated driver licensing (GDL) in Oklahoma 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 Oklahoma 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.
13. You approach an intersection with no signs or signals, and another vehicle approaches from a cross street at about the same time. Who should yield?
Show answer & explanation
Correct answer: A. At an uncontrolled intersection, slow down and yield to any vehicle that reaches it at about the same time from your right. Without signs, this default rule sorts out conflicts. Same tiebreaker as a four-way stop: right goes first.
14. What is the three-second following rule in good weather?
Show answer & explanation
Correct answer: A. Pick a fixed mark. When the car ahead passes it, count one-thousand-one, two, three. You should not reach the mark sooner. That gap grows with speed. Double it in rain; triple it on ice. Testers treat this as the core distance question.
15. An orange triangle with a red border is mounted on the back of a vehicle ahead. What is that vehicle doing?
Show answer & explanation
Correct answer: B. The slow-moving-vehicle emblem marks farm and other equipment that usually travels 25 mph or less. Give it a wide berth and pass only when you can see far enough ahead. Orange triangle equals slow vehicle.
16. When an Oklahoma railroad warning is active, how far from the nearest rail must you stop?
Show answer & explanation
Correct answer: A. Oklahoma requires a stop within 50 feet but not less than 15 feet from the nearest rail when a railroad signal, gate, or approaching train warns you. Do not proceed until you can cross safely. Never drive around a lowered gate.
17. Your 20-year-old cousin is the designated driver tonight in Oklahoma. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In Oklahoma, drivers under 21 violate the zero-tolerance law once their BAC reaches any detectable amount. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
18. How does the official NHTSA NDR code book label leaving a crash without aiding?
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. Related codes cover fatal, injury, and property-damage hit-and-run. State penalties vary; this leftover uses that official national label.
19. How many times may you take the Oklahoma Written Exam online?
Show answer & explanation
Correct answer: A. Service Oklahoma says you may take the Written Exam online two times. After two fails on the online version, you will need to come see us in person for further attempts. The Written Exam can be taken as many times as needed overall.
20. When must Oklahoma headlights be used as a clock rule, and how far away must you dim for an oncoming vehicle?
Show answer & explanation
Correct answer: A. Oklahoma requires headlights beginning 30 minutes after sunset and 30 minutes before sunrise. Dim high beams within 1,000 feet of an oncoming vehicle or within 600 feet of the vehicle you are following. Those dim distances are longer than in many other states.
21. A friend says every US interstate is 80 mph. In Oklahoma, the highest posted highway limit is actually:
Show answer & explanation
Correct answer: A. Interstate limits vary. Oklahoma tops out at 80 mph where posted. Learn the number for your state, then obey the sign in front of you, which is often lower.
22. What does NHTSA say is the only true way to protect yourself against drowsy driving?
Show answer & explanation
Correct answer: A. Official NHTSA drowsy-driving guidance says Getting adequate sleep on a daily basis is the only true way to protect yourself against the risks of driving when you’re drowsy. Coffee and energy drinks last only a short time.
23. BAC measures the percentage of alcohol in a person's blood. For drivers 21 and older in Oklahoma, what BAC puts them at or over the legal limit?
Show answer & explanation
Correct answer: C. BAC stands for blood alcohol concentration. In Oklahoma, 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.
24. An Oklahoma flashing red light is showing. What should you expect?
Show answer & explanation
Correct answer: A. Oklahoma’s flashing red light means stop. It is used at dangerous intersections where crossing traffic may not stop. Come to a smooth stop, then enter carefully. Do not speed up to beat the flash.
25. What is the first official NHTSA TireWise step if you have a tire blowout while driving?
Show answer & explanation
Correct answer: A. Official NHTSA TireWise blowout guidance says Hold the steering wheel with both hands. Gradually release the accelerator. Once your vehicle has stabilized, continue to slow down and pull off the road where and when you judge it’s safe to do so. Any overreaction – including slamming on the brakes – can result in a loss of control over the vehicle.
26. In Oklahoma, supervised behind-the-wheel practice with a permit can begin once a teen reaches which age?
Show answer & explanation
Correct answer: C. Supervised practice starts at 15 in Oklahoma, once the teen holds a learner's permit. Every practice hour with a licensed adult builds judgment that classroom study alone cannot teach, which is why the permit stage exists.
27. Who may legally park in a space reserved for people with disabilities?
Show answer & explanation
Correct answer: C. Reserved accessible spaces are only for vehicles showing a valid disability placard or plate, used when the person it was issued to is aboard. These wide, close-in spots are essential access, which is why enforcement is strict everywhere.
28. 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.
29. 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.
30. On its fastest highways, Oklahoma allows a top posted speed limit of which value?
Show answer & explanation
Correct answer: A. The highest speed limit in Oklahoma is 80 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.
