1. 1. How far before an obstructed view does the manual prohibit passing?

   1. Within 500 feet
   2. Within 10 feet
   3. Within 100 feet
   4. Only at the exact point where the view disappears
   Show answer

   Within 100 feet. Passing is prohibited within 100 feet of an obstructed view because a driver may not see an approaching vehicle, pedestrian, or other conflict soon enough. The rule applies even if the road has no painted no-passing symbol at that exact location. Ten feet is too short to provide a meaningful safety margin, while 500 feet is not the stated threshold. Treat hills, curves, and listed crossing areas as places to wait rather than gamble on visibility.

2. 2. You are waiting to turn left at a green light. An oncoming car is close, and a gap will come after it. What should you do?

   1. Turn now, since you were waiting first
   2. Turn now, but speed up to beat the car
   3. Turn now, since a green light is yours
   4. Yield, then turn when there is enough room
   Show answer

   Yield, then turn when there is enough room. When making a left turn, the manual says to yield to all oncoming traffic, slow down and stop if you have to, and go only when there is enough clear distance to turn without interfering with oncoming traffic. Waiting first, having a green light, or accelerating hard does not change that. Keep your wheels straight while you wait, so a rear-end impact cannot push you into oncoming cars.

3. 3. When leaving a private driveway, where must a driver stop before proceeding?

   1. Before the sidewalk or crosswalk, then proceed when it is safe
   2. At the edge of the public road after entering its traffic lane
   3. Only after a vehicle on the public road signals permission
   4. At the driveway entrance until the next traffic signal turns green
   Show answer

   Before the sidewalk or crosswalk, then proceed when it is safe. A driver leaving a private driveway must stop before reaching the sidewalk or crosswalk, then wait for a safe opportunity to enter or cross the public road. Reaching the traffic lane first is too late, and another driver’s signal is not the rule that controls this movement. A traffic signal at the distant intersection does not govern the driveway entrance. Stop at the pedestrian crossing point, check for people and vehicles, and continue only when the path is safe.

4. 4. You find an open curb space whose front edge is about 10 feet from a fire hydrant. May you park there in Oklahoma?

   1. No, you must be at least 15 feet away
   2. Yes, as long as you stay inside the car
   3. Yes, the limit is only 5 feet
   4. Yes, if it is during daytime
   Show answer

   No, you must be at least 15 feet away. Oklahoma law lists places where it is illegal to stop, park, or leave a vehicle, and one is within 15 feet of a fire hydrant. Ten feet is inside that distance, so the space is off-limits. Staying in the car or parking only during the day does not create an exception, because the law applies at any hour. Look for a space at least 15 feet from the hydrant, and remember the separate 20-foot rule for crosswalks at intersections.

5. 5. A raised traffic island splits the road ahead, and this sign stands at its tip. Which way should you go?

   
   1. To the left of the island, in the oncoming side
   2. Around the right side of the island
   3. Either side, whichever has less traffic
   4. Stop at the island and wait for a signal
   Show answer

   Around the right side of the island. This regulatory sign shows an arrow curving to the right of an obstruction, and the manual's meaning is to keep right of an object or center divider. Passing on the left side of the island would put you on the side meant for traffic coming the other way. The sign does not give you a choice of sides, and there is no need to stop. Regulatory signs like this one must be obeyed for everyone's safety.

6. 6. On a dry, sunny afternoon with light traffic, you are on a two-lane state highway posted at 65 mph. Under the Basic Speed Rule, may you drive 65 mph?

   1. Yes, if conditions are ideal and it is safe
   2. No, the Basic Speed Rule caps all roads at 55
   3. No, two-lane roads always require 10 mph less
   4. Yes, and up to 70 since conditions are good
   Show answer

   Yes, if conditions are ideal and it is safe. The Basic Speed Rule does not set an exact speed limit; it means the speed you may drive is limited by current conditions. The posted limit is the highest speed allowed under ideal conditions, so on a dry, clear afternoon with light traffic you may drive up to 65 mph if it is safe. The same road at night in rain or fog would call for less. Good conditions never allow going over the posted limit.

7. 7. A driver has had only one drink and plans to drive because the amount is small. What does the manual say about the effect of such a small amount?

   1. It wears off before the driver reaches the car
   2. Even a small amount reduces judgment and the ability to act quickly
   3. It affects only drivers who are under 21
   4. It matters only if the driver is over the legal limit
   Show answer

   Even a small amount reduces judgment and the ability to act quickly. The manual says that even a small amount of alcohol or drugs will reduce your ability to judge a driving situation, decide what to do and act quickly. In an emergency you need good judgment, coordination and quick reactions to avoid injury or damage. The effect does not wait until a legal limit is reached, is not limited to young drivers, and does not simply fade before you start the car.

8. 8. An animal suddenly runs in front of your vehicle. What does the Oklahoma manual say?

   1. Swerve sharply into the other lane to miss it
   2. Do not swerve; that can cause a worse crash
   3. Swerve onto the shoulder, then brake hard
   4. Speed up so the animal has time to escape
   Show answer

   Do not swerve; that can cause a worse crash. If a deer or other animal darts into your path, the manual says not to swerve to avoid it, because swerving may result in a more serious crash than hitting the animal would. Swerving into another lane or onto the shoulder is the move the manual warns against, and speeding up does not help either. To lower the risk, use caution at dawn and dusk, slow down when an animal is standing near the roadway, and scan the sides of the road.

9. 9. Besides vehicles hauling explosives or flammable liquids, which vehicles are required by Oklahoma law to stop at railroad crossings?

   1. Pickup trucks and cars that are pulling a trailer
   2. Any truck with more than two axles
   3. Motorcycles and cars towing campers
   4. School buses, church buses, and motor coaches
   Show answer

   School buses, church buses, and motor coaches. Oklahoma law requires school buses, church buses, motor coaches, and any vehicles hauling explosives or flammable liquids to stop at railroad crossings. When you follow one of these vehicles, expect it to stop at the tracks even when no train is in sight, and be ready to stop behind it. Size alone does not trigger the rule, so a pickup with a trailer or a truck with extra axles is not on the list unless it carries one of those dangerous loads. Motorcycles are not on the list either.

10. 10. You are on a one-way street and want to turn left onto another street. Which lane should you turn from?

    1. The right-hand lane, nearest the right curb
    2. The left-hand lane, nearest the left curb
    3. The middle lane, to leave room on both sides
    4. Any lane, as long as you signal first
    Show answer

    The left-hand lane, nearest the left curb. On one-way or divided streets, the manual says to always turn from the lane nearest the curb on the side you are turning toward. For a left turn on a one-way street, that is the lane along the left curb. When driving straight you may use any lane, but the extreme right and left lanes are the ones meant for turning. Turning from the middle lane or the far right crosses the path of drivers going straight, and signaling does not make a wrong-lane turn acceptable.

11. 11. How does the Oklahoma manual describe black ice?

    1. A clear icy coating on the road that you can't see
    2. A thick dark layer of ice that forms on gravel roads
    3. Ice mixed with oil that turns the road black
    4. Frozen slush pushed to the edge by snowplows
    Show answer

    A clear icy coating on the road that you can't see. The manual calls icy roads dangerous and asks for extreme care, especially on black ice, which it describes as a clear icy coating on the road surface that you can't see. That is why the manual says to stay alert for black ice even on roads or spots that seem clear. It is not dark or thick, and it is not slush at the roadside. Since there is very little you can do once a skid starts, the manual calls prevention the best skid control.

12. 12. You are approaching a crossing marked with a NO TRAIN HORN sign. Can a train engineer still sound the horn there?

    1. No, horns are switched off in a Quiet Zone
    2. Yes, engineers may still sound it when appropriate
    3. Only at night, between sunset and sunrise
    4. Only when the crossing has no gates or lights
    Show answer

    Yes, engineers may still sound it when appropriate. A NO TRAIN HORN sign marks an active Quiet Zone, where trains do not blow their horn during normal operation. The manual adds that train engineers still reserve the right to blow the horn when appropriate, such as in an emergency or for other safety reasons. A quiet crossing is not a promise of silence, and it is never a reason to listen less carefully or skip looking both ways. Quiet Zone crossings may also have extra safety features, but the time of day does not decide when a horn may sound.

13. 13. The main signal is red, but a green arrow pointing right is lit beside it. You want to turn right. What may you do?

    1. Turn right in the direction of the arrow
    2. Wait for the red light to turn green
    3. Go straight, since a green signal is lit
    4. Turn left, since any green arrow allows turns
    Show answer

    Turn right in the direction of the arrow. When a green arrow is lit, the manual says you may turn in the direction of the arrow, even when the red light is still on. A right green arrow therefore allows your right turn without waiting for the circular red to change. It does not allow you to go straight or to turn the other way; you can only make the turn the arrow shows unless signs say otherwise. Yield to pedestrians and vehicles still in the intersection.

14. 14. When a large truck approaches from the opposite direction on a two-lane road, what does the Oklahoma manual say about the wind turbulence between you?

    1. It sucks the vehicles together, so steer left
    2. It only matters if the truck is speeding
    3. It pushes vehicles apart, so keep to the right
    4. It is strongest when you drive near the shoulder
    Show answer

    It pushes vehicles apart, so keep to the right. When you meet a truck coming from the opposite direction, the manual says to keep as far to the right as possible, both to avoid being sideswiped and to reduce the wind turbulence between you and the truck. It also explains that the turbulence pushes vehicles apart; it does not suck them together. Steering toward the truck would be a mistake. Hold your lane firmly, stay right, and expect a push of air as the truck goes by.

15. 15. You are in the right lane and pass this sign as another roadway joins from the right. Do you have to merge with the joining traffic?

    
    1. Yes, the two roads form one lane right away
    2. Yes, joining cars have the right-of-way
    3. No, but you must speed up to stay ahead
    4. No, a new lane is added; watch that lane
    Show answer

    No, a new lane is added; watch that lane. This sign shows two roadways coming together ahead with a new lane added for the joining road. The manual says you do not have to merge, or form one line, but you should watch for traffic in the new lane. That is different from a merge sign, where traffic moves into your lane and you must adjust to let it in. Keep your lane, check the added lane before any lane change, and do not race the joining cars.

16. 16. To avoid carbon monoxide poisoning, what does the Oklahoma manual say to do with the fresh-air vent in congested traffic?

    1. Open it as wide as possible to pull in more air
    2. Switch it on and off every few minutes
    3. Leave it as it is; it makes no difference
    4. Close it while you are in congested traffic
    Show answer

    Close it while you are in congested traffic. The manual's tips for avoiding carbon monoxide include having your exhaust checked regularly, listening for any unusual roar from under the car, and never letting the engine run in a closed garage. In congested traffic, close the fresh-air vent, since you may be breathing exhaust from the cars around you; on highways in cold weather, open it. Opening the vent wide in a traffic jam would draw in more of those fumes. Because the setting matters, the manual gives advice for both situations.

17. 17. What does the Oklahoma manual warn about driving with your elbow resting out the window?

    1. It is fine on long trips because it reduces tiredness
    2. It is allowed only when using arm signals
    3. You lack full control, and a sideswipe could injure it
    4. It helps other drivers see you are paying attention
    Show answer

    You lack full control, and a sideswipe could injure it. The manual's posture advice includes a firm warning: don't drive with your elbow out the window. In that position you don't have full control of the steering wheel, and a side-swipe collision could take off your arm. Comfort on a long trip is not a reason to do it, and resting an elbow outside is not the same as giving a brief arm signal. Keep both hands on the wheel with at least one-third of the wheel between them.

18. 18. After stopping at a red light, you begin a legal right turn. Who must you yield to?

    1. Only the cars approaching from your left side
    2. Only pedestrians inside a marked crosswalk
    3. All pedestrians and vehicles, including bicycles
    4. No one, since you already stopped
    Show answer

    All pedestrians and vehicles, including bicycles. Oklahoma allows a right turn on red after a complete stop unless a sign forbids it, but the stop does not give you priority. The manual says that when you turn, you must yield to all pedestrians and vehicles using the intersection, including bicycles. Looking only to the left can miss a cyclist or a person crossing from the right, and people crossing in an unmarked crosswalk count too. Make the turn only after everyone using the intersection is clear of your path.

19. 19. You have checked your mirrors and signaled to change lanes. What should you do next before moving over?

    1. Look over your shoulder toward the lane you are entering
    2. Move over slowly, since the mirrors cover every angle
    3. Tap your brakes to warn the car behind you
    4. Speed up so you can move over more quickly
    Show answer

    Look over your shoulder toward the lane you are entering. The manual's lane change steps are to watch for clearance ahead and behind, check your rearview mirrors, signal, and then look over your shoulder in the direction you will be moving, followed by another look behind to both sides and a check of your blind spots. Mirrors leave blind spots, so relying on them alone can hide a car beside you. Braking or speeding up does not replace the head check. Never change lanes until you are sure it is safe.

20. 20. Your light is green, but traffic is backed up through the intersection and there is no room on the other side. What should you do?

    1. Enter and wait in the intersection for space
    2. Go, since the green gives you the right-of-way
    3. Stop before the crosswalk until traffic moves
    4. Pull into the crosswalk so you can go first
    Show answer

    Stop before the crosswalk until traffic moves. When stopped traffic is blocking an intersection, the manual says to stop before reaching the crosswalk and wait for the traffic to move. A green light lets you go only when you can actually get through. Pulling into the intersection or the crosswalk would leave you stuck there, blocking cross traffic and people on foot when the light changes. Wait behind the crosswalk until there is room for your whole vehicle on the far side.
