1. What is the maximum piston displacement allowed for a motorcycle ridden by a person under 16 with restriction code 0?
Answer: 300cc. Restriction code 0 limits riders under 16 to vehicles with a piston displacement of no more than 300cc.
Oklahoma driver handbook, page 14: “Riders under 16 are restricted to a motor scooter or motorcycle with piston displacement of no more than 300cc”
2. If you miss your exit on a controlled-access highway, what is the correct procedure?
Answer: Keep driving to the next exit, get off, and re-enter in the other direction. The handbook instructs drivers to continue to the next exit rather than crossing the median or turning around on the highway itself.
Oklahoma driver handbook, page 34: “Keep driving to the next exit, get off and re-enter the highway in the other direction.”
3. Why should drivers keep to the far right side of the road when meeting a truck coming from the opposite direction?
Answer: To avoid being sideswiped and to reduce wind turbulence between vehicles. The handbook states that staying right helps avoid sideswipes and reduces the effect of wind turbulence pushing vehicles apart.
Oklahoma driver handbook, page 54: “When you meet a truck coming from the opposite direction, keep as far as possible to the right side of the road to avoid being sideswiped and to reduce the wind turbulence between you and the truck.”
4. What is the maximum speed for vehicles displaying the Slow Moving Vehicle (SMV) emblem?
Answer: Less than 25 MPH. The handbook defines SMVs as traveling at speeds of 25 MPH or less, making 'Less than 25 MPH' the correct category among the choices.
Oklahoma driver handbook, page 58: “This emblem is used on Slow Moving Vehicles (SMVs) such as agricultural equipment, highway and roadside construction equipment and highway maintenance equipment traveling on public highways at speeds of 25 MPH or less.”
5. What is the maximum speed limit for a motor scooter or motorcycle under restriction code 0 if the engine size is less than 150cc?
Answer: 35 mph. For vehicles under restriction code 0 with engines smaller than 150cc, the speed limit is capped at 35 mph.
Oklahoma driver handbook, page 14: “If the motor scooter or motorcycle is less than 150cc, there is an additional restriction that you may not exceed 35 mph”
6. When approaching an intersection or merge area with a solid white line, what is the rule regarding passing?
Answer: Passing is hazardous and should be avoided. The handbook states that passing is hazardous in these specific situations, implying it should be avoided.
Oklahoma driver handbook, page 32: “Solid White Line—Traffic moves in the same direction on each side of the line, but passing is hazardous, as when you’re approaching an intersection or merge area.”
7. Under what condition is a bicyclist permitted to occupy the full lane rather than riding as far right as possible?
Answer: When the lane is too narrow for both a car and a bicycle to safely share the lane side by side. The handbook lists specific scenarios where taking the full lane is safest, including when the lane width is insufficient for side-by-side sharing.
Oklahoma driver handbook, page 52: “The lane is too narrow for both a car and a bicycle to safely share the lane. In this case, it is safest to let the bicycle take the full lane.”
8. If an officer signals you to stop while you are driving in the left lane, where must you pull over?
Answer: To the right shoulder. The rule requires pulling over to the right shoulder regardless of the lane you are currently occupying.
Oklahoma driver handbook, page 29: “If an officer signals you to stop while you’re driving in the left lane, you must still pull over to the right shoulder, even if that means crossing several lanes of traffic.”
9. According to the handbook, how many seconds should you maintain behind the vehicle in front of you when driving in bad weather?
Answer: 4 seconds. The handbook states to allow 4 seconds of following distance in bad weather conditions.
Oklahoma driver handbook, page 34: “Stay 3 seconds behind the vehicle in front of you. Allow 4 seconds in bad weather.”
10. Which restriction code indicates that a driver must be accompanied by a licensed driver aged 21 or older?
Answer: Code 9. Code 9 is specifically defined as requiring an accompanying licensed driver who is at least 21 years old.
Oklahoma driver handbook, page 14: “9 = Accompanied by licensed driver 21 years of age or older in the front seat. For people learning to drive.”
11. If you are already crossing the tracks and the warning lights begin flashing or the gates start coming down, what should you do?
Answer: Keep moving to finish driving through the crossing. The instructions state that if you are already on the tracks when signals activate, you should continue moving rather than stopping or backing up.
Oklahoma driver handbook, page 57: “If you are crossing the tracks and the warning lights begin flashing or the gates start coming down, don’t stop. KEEP MOVING!”
12. When turning on a one-way street, from which lane should you turn?
Answer: The lane nearest the curb. The handbook specifies that when turning on one-way streets, drivers must initiate the turn from the lane closest to the curb.
Oklahoma driver handbook, page 38: “When you are turning on one-way or divided streets, always turn from the lane nearest the curb.”
13. What is the correct procedure for a driver passing a bicycle on a narrow roadway when the rider may not be aware of the vehicle?
Answer: Honk the horn briefly as a signal that you are going to pass. The handbook advises a brief horn honk to signal intent without startling the rider, distinguishing this from blasting the horn.
Oklahoma driver handbook, page 51: “If you are about to pass a bicycle on a narrow roadway and you think the rider doesn’t know you’re coming, honk your horn briefly as a signal that you’re going to pass.”
14. Within what distance must you dim your high beam headlights when approaching an oncoming vehicle?
Answer: Within 1000 feet. The rule specifies dimming high beams within 1000 feet for oncoming traffic, distinct from the 600 feet rule for following vehicles.
Oklahoma driver handbook, page 59: “Dim your high beam headlights to low beams within 1000 feet of an oncoming vehicle or within 600 feet of the vehicle you are following.”
15. How should you interpret diagonal stripes sloping downward to the right on a warning sign or barricade?
Answer: Bear to the right. The handbook states that stripes sloping downward to the right indicate that drivers should bear to the right.
Oklahoma driver handbook, page 22: “Stripes sloping downward to the right mean bear to the right.”
16. When starting on a hill, who has the right-of-way as you merge into traffic?
Answer: The drivers already traveling in the lane. The handbook states that drivers already in the lane have priority over the vehicle merging from the curb.
Oklahoma driver handbook, page 48: “It will be your responsibility to wait for an opening and move safely into the proper lane, as the drivers already traveling have the right-of-way.”
17. What is the recommended action if your vehicle begins to skid on an icy road?
Answer: Take your foot off the brake and turn the steering wheel in the direction of the skid. The handbook advises releasing the brake and steering into the skid to correct the vehicle's path, provided it is safe to do so.
Oklahoma driver handbook, page 43: “As a general rule, if the car starts to skid, take your foot off the brake and turn the steering wheel in the direction of the skid if you can do so without running off the road, hitting something or steering into oncoming traffic.”
18. How should a driver behave when approaching a bicyclist at a stop sign if there is no immediate hazard present?
Answer: Slow down and proceed without stopping if no danger is present. The guidelines state that cyclists must slow down but are allowed to proceed without a full stop at stop signs if no immediate hazard exists.
Oklahoma driver handbook, page 52: “If no danger is present, cyclists can proceed without stopping.”
19. What action is required when approaching a red octagonal STOP sign at an intersection?
Answer: Come to a complete stop before the pedestrian crosswalk. The handbook mandates a complete stop before the crosswalk, regardless of whether the crosswalk is marked.
Oklahoma driver handbook, page 19: “STOP: RED OCTAGON— Come to a complete stop at the intersection. You must stop before the pedestrian crosswalk, even if it isn’t marked.”
20. When approaching a railroad grade crossing, within what distance from the nearest rail must a driver stop?
Answer: Within 50 feet but not less than 15 feet. The handbook defines the stopping zone as being between 15 and 50 feet from the nearest rail.
Oklahoma driver handbook, page 56: “the driver of such vehicle shall stop within 50 feet but not less than 15 feet from the nearest rail of such railroad”
