1. What is the safest way to deal with the situation this sign announces?
Show answer
Answer B: Match the speed of the other traffic stream and open a gap so vehicles can blend without hard braking
Blending works when speeds are matched and gaps are opened, so nobody has to brake hard or swerve where the two streams come together.

2. How much moving water is generally enough to float and carry away most passenger vehicles?
Show answer
Answer D: About one foot
About a foot of moving water will float most cars, and even less will stall an engine. That is why the rule is to turn around instead of judging the depth.

3. A stop line is painted across the pavement at this sign. Where must the vehicle come to rest?
Show answer
Answer A: Behind the stop line, with no part of the vehicle across it
The vehicle must halt behind the stop line; where no line is painted the driver stops before the crosswalk, and where there is neither, before entering the intersection.
-
4. You park facing downhill on a one-way street where the curb is on your left. Which way do the front wheels go?
Show answer
Answer A: Left, toward the curb on that side
Standard practice follows the curb rather than the side of the road: facing downhill the wheels point into the curb so a rolling vehicle is stopped by it. States differ on whether this is legally required.

5. The red oil pressure warning light comes on while you are driving. What should you do?
Show answer
Answer C: Pull over safely as soon as possible and shut off the engine
Loss of oil pressure means the engine is no longer being lubricated and can be destroyed within minutes. Stop, shut down and check before restarting.
-
6. What is the safest way to leave a perpendicular parking space in a busy lot?
Show answer
Answer B: Back out slowly, checking both ways and yielding
Backing out gives you the poorest view of any maneuver, so it must be done slowly, with checks in both directions and with yielding to whoever is already there.
-
7. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.

8. Where in the United States may a motorcycle ride between lanes of traffic?
Show answer
Answer C: Only where a state has specifically authorized it
Riding between lanes is prohibited in most states and permitted only where a state law expressly allows it, so a rider must know the rule for the state being ridden in.
-
9. How long should a young child ride in a rear-facing child seat?
Show answer
Answer D: Until the child outgrows the height or the weight limit of the seat
Rear facing is the safest position and should be kept until the child reaches the top height or weight allowed by the seat.
-
10. Why is the road often most slippery during the first few minutes of rain after a long dry spell?
Show answer
Answer C: Oil and dust on the surface mix with the water into a slick film
Oil drippings and road dust build up on dry pavement, and the first light rain lifts them into a slippery film before heavier rain washes it away.
-
11. At what distances must an Oklahoma driver dim high-beam headlights to low beams?
Show answer
Answer B: 1000 feet from an oncoming vehicle, or 600 feet from a vehicle being followed
Oklahoma requires dimming high beams to low beams within 1000 feet of an oncoming vehicle, or within 600 feet of a vehicle being followed.

-
13. A curb sign reads No Standing. What does it allow you to do?
Show answer
Answer B: Stop only long enough to pick up or drop off passengers
No Standing bars waiting for any purpose except the brief moment needed to let passengers in or out, which is stricter than No Parking.
-
14. Who must wear a seat belt under Oklahoma's mandatory safety requirements?
Show answer
Answer A: Every driver and front seat passenger
Oklahoma requires every driver and front seat passenger to wear a properly adjusted and fastened factory installed seat belt, and officers may stop a vehicle for that violation alone.
-
15. How does alcohol affect a driver's ability to handle several things at once?
Show answer
Answer B: It cuts the ability to divide attention between tasks
Driving means watching the road, the mirrors and the instruments together, and alcohol narrows attention so that one of those tasks is dropped without the driver noticing.
-
16. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
17. A bicycle symbol topped by two chevrons is painted in the middle of a travel lane. What does that marking indicate?
Show answer
Answer D: Bicyclists share the lane with motor vehicles and may ride away from the curb
A shared lane marking shows drivers where bicyclists are likely to ride in a lane used by both bicycles and motor vehicles.
-
18. How do you avoid the sharp nod at the end of a stop?
Show answer
Answer A: Ease the pedal pressure off slightly just before the vehicle stops
The nod comes from the suspension unloading at the instant the wheels stop. Releasing a little pressure at the end lets the vehicle settle smoothly.
-
19. You are involved in a collision, even a minor one. What is your first legal duty?
Show answer
Answer A: Stop at or near the scene without blocking traffic more than necessary
Every driver involved in a crash must stop at the scene, and leaving before meeting that duty is a serious offense. Move the vehicles only as far as needed to clear the traffic lanes.
