1. A yellow diamond shows an arrow that doubles back on itself. What kind of curve lies ahead?
Show answer
Answer C: A turn of 135 degrees or more, nearly doubling back
The hairpin curve sign is used where the road changes direction by 135 degrees or more, and it is normally backed up by chevrons or a large arrow through the bend.
-
2. Where is the clutch lever located on a standard motorcycle?
Show answer
Answer D: On the left handlebar
Squeezing the lever on the left handlebar disengages the clutch and interrupts power between the engine and the rear wheel.
-
3. A driver who wants to reverse direction arrives at this sign. What is allowed?
Show answer
Answer C: Going on and reversing direction only where the maneuver is permitted
The restriction removes that maneuver at that spot entirely, so the driver has to continue and turn the vehicle around at a place where it is not prohibited.
-
4. You are parking on a one-way street where parking is allowed on both sides. What must still be true?
Show answer
Answer D: The vehicle must face the direction the traffic flows
Either curb may be used on a one-way street where signs allow it, but the vehicle must always be headed in the direction traffic moves.
-
5. A sign on a long descent points to a RUNAWAY TRUCK RAMP a mile ahead. What is that ramp for?
Show answer
Answer C: Stopping a vehicle whose brakes have failed
An escape ramp climbs into deep gravel or sand to bring a vehicle with failed brakes to a halt, so no one should stop or park in it.
-
6. At a four-way stop you and an opposing driver arrive together. You are going straight and the other driver is turning left across your path. Who goes first?
Show answer
Answer B: You do, because the left turn crosses your path
When two opposing drivers arrive together, the one going straight goes first and the left-turning driver yields.
-
7. Loose gravel has been swept into the middle of your lane on a downhill bend. Which controls are affected most?
Show answer
Answer D: Steering and braking, since the loose stones roll under the tires
Gravel rolls between rubber and pavement, so the tires can neither turn the vehicle nor slow it as they would on a clean surface.
-
8. You have finished a distracting task and your eyes are back on the road. What is true?
Show answer
Answer A: Your full attention takes a while to come back
Studies of drivers show attention lags behind the eyes for many seconds after a phone or a screen task, so the danger continues after the task is over.
-
9. Why are ordinary denim jeans a poor choice for riding?
Show answer
Answer C: They wear through in a slide, giving little abrasion protection
Light denim abrades away in a fraction of a second on pavement, while leather or purpose made textile gear stays intact long enough to protect the skin underneath.
-
10. A pedestrian with a white cane draws the cane back and steps away from the curb as you approach. What does that usually mean?
Show answer
Answer B: They are signaling you to go ahead and drive on
Pulling the cane in and stepping back from the curb is the customary way a blind pedestrian tells drivers to proceed.
-
11. An overhead lane-use control signal shows a steady red X above the lane you are traveling in. What does it require?
Show answer
Answer D: Leave that lane, because it is closed to you
A steady red X means road users are not permitted to use the lane beneath it, so you must move into a lane that is open.
-
12. What training does Oklahoma require of an applicant under 18 seeking a motorcycle endorsement?
Show answer
Answer A: A certified state approved motorcycle basic rider course
Since August 26, 2016 Oklahoma has required anyone 17 or younger to complete a certified state approved motorcycle basic rider course before receiving a motorcycle endorsement.
-
13. Why does even a small reduction in speed matter so much where people are walking?
Show answer
Answer D: Because a pedestrian struck at a lower speed is far more likely to survive
The chance that a pedestrian survives falls steeply as impact speed rises, so a few miles per hour can decide the outcome.
-
14. Compared with dry pavement, how much room does a vehicle need to stop on packed snow?
Show answer
Answer D: Several times as much
Grip on packed snow is a fraction of that on dry pavement, so stopping distance grows several times over. Antilock brakes help you steer, not stop shorter.
-
15. What is a good rule for any task you want to do inside the vehicle?
Show answer
Answer D: If it needs more than a moment, do it stopped
A glance of a second or two is manageable, but any task that runs longer belongs to a stopped vehicle, because the road does not pause while you do it.
-
16. A fire truck with lights and siren has just passed you and is heading down the same road. How closely may you follow it?
Show answer
Answer B: Well back, because following a responding emergency vehicle closely is illegal
Following a responding emergency vehicle closely is prohibited; the exact minimum distance is set by each state, so stay far enough back to keep the scene and other responders clear.
-
17. Where does a rider find the correct chain slack figure for a particular motorcycle?
Show answer
Answer B: In the owner manual for that motorcycle
Correct slack varies from model to model, so the manufacturer specification in the owner manual is the only reliable figure.
-
18. Snow has covered the pavement markings on a two-lane road. How should a driver judge lane position?
Show answer
Answer B: By the tracks of other traffic and the roadside features
With the markings hidden, ruts left by earlier traffic, signs, poles and the line of the shoulder are the best clues to where the lane runs.
-
19. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
-
20. Children are playing close to the edge of a residential street. What is the right speed choice?
Show answer
Answer D: Well below the limit, slow enough to stop for a sudden dash
Children can step out without warning, so the safe speed is the one that lets you stop within the distance you can see to be clear.
