1. Is it acceptable to drive far below the flow of traffic on an open highway?
Show answer
Answer B: No, driving too slowly can obstruct traffic and create a hazard
Traffic that is much slower than the surrounding flow forces other drivers into sudden braking and unnecessary passing maneuvers, and impeding traffic is itself a violation.
-
2. The crossbuck, formed by two rectangular arms crossed in an X, is placed
Show answer
Answer D: on each highway approach to a railroad grade crossing
The crossbuck marks the location of a highway-rail grade crossing and is required on each highway approach to that crossing.
-
3. Traffic is heavy and crawling where a sign warns that your lane ends and two lanes must become one. What is the best practice?
Show answer
Answer C: Use the lane to the end, then take turns merging one by one
In stop-and-go traffic the zipper merge, using both lanes up to the merge point and then alternating, keeps the queue shorter and traffic moving; in free-flowing traffic move over as soon as it is safe.
-
4. You are turning right from a one-way street onto a two-way street. Where should the turn end?
Show answer
Answer A: In the lane nearest the right curb of the street you are entering
A right turn starts and finishes as close to the right as practical, so you leave the one-way street from the right lane and arrive in the lane nearest the right curb.
-
5. A bicyclist is riding around a single-lane roundabout in the middle of the lane as you wait to enter. What is your duty?
Show answer
Answer C: Yield to the bicyclist just as you would to a car
A bicyclist using the roundabout is traffic like any other vehicle and has the same claim to the circulating lane.
-
6. What is a microsleep?
Show answer
Answer D: A few seconds of sleep, sometimes with the eyes open
A microsleep is an involuntary lapse of a few seconds during which the driver is asleep and the vehicle travels blind, often without the driver knowing.
-
7. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?
Show answer
Answer D: Only at the openings where the solid lines are broken
The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.
-
8. You are approaching a narrow bridge where the road has one lane in each direction and no shoulder. What should you do about passing?
Show answer
Answer B: Do not pass on or near the bridge
A narrow bridge gives neither vehicle anywhere to go, so passing is prohibited there in the same way as on a hill or in a tunnel.
-
9. Besides school signing, which warning signs may also use a fluorescent yellow-green background?
Show answer
Answer C: Pedestrian and bicycle warning signs
Pedestrian crossing, bicycle and playground warning signs may use either the standard yellow or the fluorescent yellow-green background, which draws extra attention where people outside vehicles are present.
-
10. A sign reads REDUCED SPEED LIMIT AHEAD. What does it tell you?
Show answer
Answer D: A lower limit begins further along the road
The sign gives advance notice so a driver can slow gradually, and the new figure takes effect at the speed limit sign that follows.
-
11. A person in a wheelchair is traveling in the roadway because the sidewalk is blocked by construction. What should you do?
Show answer
Answer B: Pass slowly with plenty of room, or wait
A blocked sidewalk leaves the person no choice but the road, and a chair cannot move aside quickly, so pass wide and slow or wait for room.
-
12. A flashing red arrow is displayed for your turning lane. What does it require?
Show answer
Answer D: Stopping, then turning when the way is clear
A flashing red arrow is treated like a stop sign for that movement: come to a full stop, then turn when it is safe and no one has to be cut off.
-
13. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
14. A large panel mounted on a trailer at the roadside displays a flashing arrow pointing left. What does it tell you?
Show answer
Answer B: Move into the lane to your left
An arrow panel directs traffic out of a closed lane, so the arrow shows the direction you must move rather than the shape of the road ahead.
-
15. You are circulating in the inner lane of a two-lane roundabout, your exit is next, and a vehicle is beside you in the outer lane. What should you do?
Show answer
Answer C: Keep circulating around the island and take that same exit on your next time around
You may not cut across a vehicle in the outer lane; if you cannot exit safely, continue around the circle and try again.
-
16. When an Oklahoma license is suspended for failing to maintain mandatory motor vehicle insurance, what does reinstatement require beyond the standard processing fee?
Show answer
Answer B: An additional $200 trauma-care assessment fee
Reinstating an Oklahoma license suspended for failing to maintain mandatory insurance requires a $75 processing fee plus an additional $200 trauma-care assessment fee, more than the fee for most other suspensions.
-
17. What does a broken line indicate, whatever color it is painted?
Show answer
Answer C: That crossing it is permitted
A broken line always describes a permissive condition, and the color then tells the driver whether the traffic beyond it runs the same way or the opposite way.
-
18. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
-
19. Trees block the view along the tracks as a driver approaches this sign. What approach speed is correct?
Show answer
Answer B: Slow enough to stop before the nearest rail once a train comes into view
Where the view along the track is obstructed, the only safe speed is one that still leaves stopping distance after a train first becomes visible.
-
20. How should a turn at an intersection be taken on a wet road?
Show answer
Answer C: Slow earlier than usual and steer smoothly through the corner
Wet pavement leaves less grip, so the speed must come off before the turn and the steering must be gentle enough not to break traction.
