2. You are traveling beside a solid white lane line. What does it tell you?
Show answer
Answer B: Crossing it is discouraged or prohibited, so stay in your lane
A solid white line separates lanes going the same direction where lane changing is discouraged or prohibited, such as where a through lane meets a mandatory turn lane.
-
3. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.

-
5. You will leave your vehicle for several hours after dark. Where is the best place to park it?
Show answer
Answer D: In a well-lit spot with people and cameras nearby
Light, passing people and cameras all discourage theft and make your own return to the vehicle safer.
-
6. How far ahead should you normally be looking while driving?
Show answer
Answer D: About 12 to 15 seconds of travel ahead
Looking that far ahead, roughly a block in town and much farther on a highway, gives you time to see a problem developing and adjust before it becomes an emergency.
-
7. You find that the road surface has turned to sheet ice. What speed is appropriate?
Show answer
Answer A: A crawl, slow enough that you could stop without braking hard
Ice can cut grip to a fraction of normal, so stopping takes many times the usual distance and only a crawl leaves any margin.
-
8. A rectangular red sign with the white words WRONG WAY means that
Show answer
Answer C: the driver is already traveling against the legal flow and must not continue
The wrong way sign uses a white legend and border on red and addresses a driver who has entered a ramp or one-way roadway in the wrong direction, who should stop and turn around safely.
-
9. You have finished parallel parking at the curb. How should the vehicle sit?
Show answer
Answer A: Close to the curb, so that it does not stick out into the traffic lane
A parked vehicle must sit close enough to the curb that it does not intrude into the path of passing traffic; the exact maximum distance is set by each state.
-
10. Who may issue a valid Oklahoma security verification form for proof of insurance?
Show answer
Answer A: Only an insurance company or agent
Oklahoma requires that a security verification form presented as proof of insurance be issued by an insurance company or agent, not created or vouched for by the driver.
-
11. What is the rule about leaving a child or a pet in a parked vehicle?
Show answer
Answer A: Never do it; the inside can turn deadly hot very quickly
The inside of a parked vehicle heats far faster than the air outside, and cracking a window does not prevent it, so a child or animal must never be left there.
-
12. Beyond the point this sign refers to, which movement becomes unlawful?
Show answer
Answer D: Driving on the far side of the separation, against the flow
Once the two directions are separated, each roadway carries one-way traffic, so crossing to the other side means driving into oncoming vehicles.
-
13. Why is it useful to watch the vehicle two or three places ahead of you?
Show answer
Answer C: You get an earlier warning of slowing traffic than brake lights give
Trouble travels back through a line of traffic, so seeing it start several vehicles ahead gives you a head start on braking.
-
14. You realize you have driven several miles without remembering any of it. What kind of distraction is this?
Show answer
Answer C: Cognitive distraction, because your mind was not on driving
Daydreaming or being lost in thought is a cognitive distraction. Your eyes may be on the road, but your brain is not processing what they see.
-
15. You are waiting to turn left and a motorcycle is approaching from the opposite direction. Why should you take extra care judging its speed and distance?
Show answer
Answer A: Its small size makes it look farther away and slower than it really is
A motorcycle's narrow profile fools the eye, so drivers often misjudge how soon it will arrive. Left turns across an oncoming motorcycle are a leading cause of rider deaths.
-
16. How does alcohol typically affect a driver's vision?
Show answer
Answer D: It blurs vision, weakens night vision and narrows attention to the sides
Alcohol slows the eye muscles and the brain's processing of what is seen, degrading focus, night vision, depth perception and awareness of movement at the edges of the field of view.
-
17. A yellow diamond shows an arrow bent into a series of reversing turns. What does it warn about?
Show answer
Answer A: Three or more changes of direction close together
The winding road sign replaces a string of separate curve signs where several bends follow one another with only short straights between them.
-
18. A yellow diamond in which one line joins another at an angle warns that
Show answer
Answer B: traffic from another roadway will merge into the driver's lane ahead
The merge sign warns that another traffic stream will join the same lane ahead, so drivers on both roadways must adjust speed and spacing.
-
19. How many questions are on the Service Oklahoma Class D written knowledge test?
Show answer
Answer A: 20
Service Oklahoma administers a 20 question Class D written knowledge test drawn from the Oklahoma Driver Manual.
-
20. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
