Oklahoma SOK Permit Practice Test 25

1. Well before an intersection, an overhead sign shows a diagram of the lanes with an arrow above each one. What is its purpose?

• A To tell drivers that the lanes will be closed for work ahead
• B To mark the point where a driver must have finished any pass
• C To let drivers pick the correct lane in good time
• D To show which lane carries the heaviest traffic at that hour

2. Why is it often safer to back into a parking space than to back out of one?

• A Because reversing into a space causes less wear on the tires and the steering
• B Because a vehicle parked nose out is less likely to be damaged by other drivers
• C Because it is the only legal way to park in a marked perpendicular space
• D Because you leave the space going forward, with a clear view

3. At an intersection where every approach carries this sign, two drivers arrive at exactly the same instant. Which of them goes first?

• A The one traveling faster on approach
• B The one intending to turn left
• C The driver on the right
• D The driver of the heavier vehicle

4. A signal stands part way up a freeway entrance ramp and turns green briefly again and again. How many vehicles does such a signal normally release on each green?

• A One for each lane of the ramp
• B As many as can pass before the red returns
• C Two per lane, so that pairs can merge together
• D Any number, since the signal only sets a rhythm

5. A yellow diamond showing the silhouette of a deer warns that

• A hunting is permitted next to the road
• B a livestock market is located ahead
• C the road passes through a wildlife refuge closed to traffic
• D large animals may cross the road in that area

6. Your vehicle is stuck in deep snow and you run the engine for heat while waiting for help. What must you check?

• A That the parking brake is off so the rear brakes do not freeze on
• B That the headlights are off so the battery is not drained during the wait
• C That the exhaust pipe is clear of snow
• D That the windows are fully closed so no cold air can get into the cabin

7. You come around a bend and find loose sand spread across your lane. What should you do?

• A Brake hard in the sand so that you are stopped before you reach the far side
• B Turn the wheel quickly from side to side to find the firm grip underneath
• C Accelerate through it so that the tires cut down to the solid surface below
• D Ease off the gas, avoid sudden braking or steering, and keep straight

8. A motorcycle ahead of you has its turn signal blinking but continues straight through several intersections. What is the likely explanation?

• A The rider is warning you that the road surface ahead is slippery
• B The rider is asking you to pass because the motorcycle is slowing down
• C The motorcycle's hazard lights are on because it has a mechanical fault
• D Motorcycle signals often do not cancel themselves after a turn

9. Why should you avoid parking over tall dry grass or a pile of dead leaves?

• A Because the leaves block the drain holes in the bottom of the doors
• B Because the hot exhaust can set the dry material on fire
• C Because damp leaves make the parking brake cable stretch and then slip
• D Because grass seeds get into the air filter and slowly choke the engine

10. A yield sign is posted where an entrance ramp meets the highway. What must you do?

• A Come to a complete stop at the sign every time before entering the highway travel lanes
• B Enter the highway first, because a vehicle on a ramp has priority at the point of the merge
• C Give way to the traffic already on the highway and merge into a gap
• D Hold your ramp speed and expect the highway traffic to change lanes in order to make room

11. An oncoming driver flashes their headlights while you are waiting to turn left. What should you do?

• A Turn at once, because flashing lights are an accepted signal to go
• B Flash back to confirm and then complete the turn without delay
• C Wait for the driver to flash a second time before you start to move
• D Judge the situation yourself, since the flash may mean something else

12. You and an oncoming driver are both turning left at the same intersection. What is the usual rule?

• A Whichever driver arrived at the intersection first turns while the other waits
• B Both drivers pass behind each other, keeping right of the center of the junction
• C The larger vehicle turns first and the smaller one follows along behind it
• D Both turn in front of each other unless markings show otherwise

13. You pass into a work zone with a reduced speed limit but you see no workers. What speed applies?

• A The normal highway limit, because the lower limit applies only while work goes on
• B The lower limit only when equipment is actually moving inside the work zone
• C Whatever your own judgment suggests, since the signs are advisory when it is quiet
• D The posted work zone limit, whether or not workers are present

14. A sign at the signal reads LEFT TURN ON GREEN ARROW ONLY. The ball turns green but no arrow appears. What may you do?

• A Turn left after yielding to oncoming traffic, as on any green ball
• B Turn left only if the oncoming lanes happen to be empty at the time
• C Wait, because your turn is allowed only while the arrow is showing
• D Enter the intersection and wait inside it until the arrow comes on

15. You are leaving a freeway on an exit ramp posted with an advisory speed of 25 mph. Where should you slow to that speed?

• A In the deceleration lane, before you reach the curve of the ramp
• B Only after you have passed the sharpest part of the curve on the ramp
• C On the freeway itself, well before you reach the entrance to the exit lane
• D At the end of the ramp, where it joins the road you are turning onto

16. A flashing red lamp is mounted above a stop sign at a rural intersection. What does it add?

• A A warning that cross traffic does not have to stop
• B Permission to roll through when nothing is coming
• C Emphasis, while the required stop stays the same
• D A duty to stop only while the lamp is flashing

17. What is the what if habit of a defensive driver?

• A Planning the exact route to be taken before turning the ignition key on
• B Deciding in advance which lane is the quickest on the daily commute
• C Thinking through what you would do if a hazard ahead of you turned bad
• D Assuming that every other driver will follow the rules exactly as written

18. On a two-lane road with a broken yellow center line, may you cross it to turn into a driveway on the left?

• A No, a yellow line may only be crossed while you are actually overtaking another vehicle
• B No, a turn across a yellow center line requires a marked left turn lane to be provided
• C Yes, when it is safe and the oncoming lane is clear
• D Yes, but only if you first stop completely while astride the center of the roadway

19. A school crossing guard has returned to the curb but two children are still walking across the road. When may you go?

• A As soon as the guard steps off the roadway and lowers the sign
• B As soon as the children have passed the middle of the roadway
• C Only after the children have reached the far sidewalk
• D Immediately, since the guard has finished

20. An overhead sign shows that the right lane is EXIT ONLY. What does that mean if you intend to stay on the highway?

• A You may stay in it as long as you continue straight ahead at the point where the exit leaves
• B You have to move out of that lane before the exit
• C You may stay in it, because an exit only lane rejoins the main highway a short distance later
• D You must slow to the ramp speed and then rejoin the main highway just beyond the exit ramp
