1. A driver who has been drinking has two cups of strong coffee. What has changed?
Show answer
Answer D: The driver is more awake but just as impaired
Coffee can make a drinker feel alert, but nothing except time removes alcohol from the blood, so a wide awake drinker is still an impaired driver.
-
2. You are descending a long steep grade with a loaded truck close behind you. What should you do?
Show answer
Answer A: Hold a steady speed and let it pass when it can
Gravity pushes a loaded truck downhill and it cannot slow quickly, so give it a predictable speed and room to get by rather than braking in front of it.

4. How can you tell a tire has reached its wear limit without measuring it?

Answer C: The wear bars across the grooves become level with the tread
Molded bars sit at the bottom of the grooves. Once the surrounding tread has worn down to them, the tire has reached the end of its safe life.

5. The school bus stop ahead sign is installed where
Show answer
Answer C: a school bus stop cannot be seen from far enough away by approaching drivers
This school warning sign is used in advance of a bus stop that lacks adequate sight distance and cannot be relocated, so drivers are warned before the stopped bus comes into view.
-
6. A school sign combined with an AHEAD plaque, or with a plaque giving a distance in feet, forms an assembly that
Show answer
Answer B: warns of a school crossing located further along the road
The school advance crossing assembly is placed before the crosswalk to give drivers notice, while a different assembly marks the crossing itself.
-
7. A child seat was in the car during a moderate crash. What should be done with it?
Show answer
Answer A: Replace it, because a seat that has been through a crash may be weakened
Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.
-
8. A deer has just crossed in front of you on a stretch signed for animal crossings. What is the best assumption?
Show answer
Answer B: More animals are likely to follow the first one
Deer travel in groups, so one animal crossing usually means others are about to follow, and a driver should slow and keep scanning both shoulders.
-
9. The car ahead drifts across the lane line and back again several times. What should you do?
Show answer
Answer C: Assume that the driver is distracted or impaired, and keep well back
Drifting is a classic sign of a distracted, drowsy or impaired driver, and distance is your protection from all three.
-
10. You have printed directions or paperwork you need to check. When should you read them?
Show answer
Answer C: Before you leave, or after you park
Reading takes eyes and mind off the road for far longer than any safe glance, and a light that changes while you read leaves you moving off blind.
-
11. A broken white line separates your lane from the lane beside it. What does it indicate?
Show answer
Answer C: Both lanes carry traffic in the same direction and lane changes are permitted
White lines separate lanes of traffic moving in the same direction, and a broken white line means changing lanes across it is permitted when it is safe.
-
12. A white diamond symbol is painted in a highway lane. What does it identify?
Show answer
Answer C: A lane reserved for high-occupancy vehicles
The diamond symbol marks a preferential lane, most often one reserved for vehicles carrying a minimum number of occupants.
-
13. In Oklahoma, what is fraudulently creating or manufacturing a counterfeit proof-of-insurance form classified as?
Show answer
Answer C: A felony
Fraudulently creating, manufacturing or counterfeiting a security verification form in Oklahoma may result in a felony conviction carrying severe fines and imprisonment.
-
14. You park on level ground in a lot. Where should the front wheels be pointing?
Show answer
Answer C: Straight ahead, so the car would not veer if it moved
On the level the wheels go straight so that the car stays in its own space, and so that a shunt from behind does not send it across a lane.
-
15. You are making a U-turn at a signal on a green left arrow. Who must you still watch for?
Show answer
Answer D: People in the crosswalk you will cross as you come around
Even a protected arrow does not clear the crosswalk, and a U-turn sweeps across a crosswalk that pedestrians may already be using.
-
16. You are driving on a rural road with no sidewalk. Where should you expect to meet pedestrians?
Show answer
Answer A: Walking toward you on your side of the road
Where there is no sidewalk, pedestrians are taught to walk facing traffic, so they appear on your side of the road coming toward you.
-
17. Where is a strong crosswind most likely to hit you suddenly?
Show answer
Answer D: Coming out of a tunnel or a cut onto an open bridge
Gusts arrive the moment you leave shelter, which is why bridge approaches and the ends of cuts and tunnels catch drivers out.
-
18. Which practice matches current child passenger safety guidance?
Show answer
Answer D: Keep a child rear facing until the top height or weight limit of the seat is reached
A rear facing seat spreads crash forces across the child's whole back, so it should be used as long as the seat allows, and never in front of an active passenger air bag.
-
19. You are on a city street with two lanes in your direction, cars parked along the curb and driveways every few yards. Which lane is usually safer?
Show answer
Answer B: The lane farther from the curb, away from opening doors and vehicles pulling out
Most of the hazards on such a street come from the curb side, so the inside lane gives you more space and more time to react.
-
20. A short driver cannot get ten inches between the chest and the steering wheel airbag. What is the answer?
Show answer
Answer D: Move the seat back and tilt the wheel downward, or fit pedal extenders
Distance from the airbag is gained by moving the seat back and aiming the wheel at the chest, using pedal extenders if the pedals are then out of reach.
