1. Which passenger rule applies to an Oklahoma intermediate license holder driving alone?
Show answer

2. A live power line is lying on your car and the car has caught fire, so you must get out. How should you leave it?
Show answer
Answer D: Jump clear without touching the car and ground at once, then shuffle away
Touching the vehicle and the ground together makes you the path to earth, and long strides can bridge the voltage spread through the ground.
-
3. Why can an oncoming vehicle that looks comfortably far away leave you far less room than you expect?
Show answer
Answer D: You and that vehicle close the gap at the sum of both your speeds
Two vehicles approaching at 55 mph each close the distance between them at about 110 mph, so the gap disappears in half the time you would expect.
-
4. How does a NO OUTLET sign differ from a DEAD END sign?
Show answer
Answer B: It warns that a whole group of streets has no way out
No Outlet is posted where the road leads into a network of streets from which there is no through route, while Dead End refers to the single street itself.
-
5. The traffic signal is green, but the crossing lights on the tracks inside the intersection begin to flash. What must you do?
Show answer
Answer C: Stop clear of the tracks and wait, even though the signal is green
Active crossing warning devices outrank the green indication, so you stop short of the rails and wait until the warning stops.
-
6. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
7. Your vehicle does not have antilock brakes and you must stop quickly on a slippery road. What is the correct technique?
Show answer
Answer B: Apply the brakes firmly without locking the wheels, releasing slightly if they lock
Locked wheels slide and cannot steer. Squeezing the brakes to just short of lockup, and easing off if they lock, gives the shortest stop with control.
-
8. After turning right you see a sign showing that your lane ends a short way ahead. What should you do?
Show answer
Answer B: Signal and merge into the next lane while there is still room
Merge early and smoothly while a gap is still available, rather than running out of pavement or forcing your way in at the last moment.
-
9. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
10. A vehicle coming toward you has drifted into your lane. What should you do?
Show answer
Answer D: Slow down, sound the horn, flash your lights and steer to the right if possible
Moving right gives the other driver space to recover and keeps you out of the lane they are most likely to return to. Braking reduces the force of any impact.
-
11. You are passing a crash on the other side of a divided highway. What should you do?
Show answer
Answer D: Keep your eyes on your own lane and the traffic around you
Staring at a crash scene, often called rubbernecking, causes sudden slowing and secondary collisions. Your attention belongs on the traffic in front of you.
-
12. A yellow diamond showing two vertical arrows, one pointing up and one pointing down, warns that
Show answer
Answer A: the road ahead carries traffic in both directions
The two-way traffic sign warns that the roadway ahead is not divided and that vehicles will be coming from the opposite direction.
-
13. How should tire pressure be checked and set?
Show answer
Answer B: When the tires are cold, set to the pressure specified by the vehicle manufacturer
Driving heats the air and raises the reading, and the sidewall number is a maximum rather than a recommendation, so check cold and use the figure on the vehicle placard or in the owner's manual.
-
14. What does a marked crosswalk tell a driver approaching a corner?
Show answer
Answer D: Where pedestrians are expected to cross and must be given way
Crosswalk markings show pedestrians where to cross and warn drivers to yield to anyone using the crossing.
-
15. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?
Show answer
Answer D: The sign that forbids entering that roadway at all
The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.
-
16. Why should the washer reservoir hold proper washer fluid rather than plain water in winter?
Show answer
Answer D: Water freezes and it leaves you with no way at all to clean the glass
Washer fluid contains antifreeze, so it still works in the cold, whereas water freezes in the reservoir and the lines.
-
17. A white regulatory sign near a state line reads BUCKLE UP IT IS THE LAW. What is it doing?
Show answer
Answer A: Reminding occupants that belt use is required
The safety belt sign restates a law that already applies, and it is usually placed where drivers enter a state or a long rural stretch.
-
18. You hold steady pressure on the brake pedal for the whole of a long descent. What is likely to happen?
Show answer
Answer B: The brakes overheat and fade, so they slow you less and less
Continuous braking heats the brakes until they fade and lose effectiveness; use a lower gear and short, firm applications instead.
-
19. In a work zone a flagger is directing traffic in a way that conflicts with the posted signs. Whom do you follow?
Show answer
Answer B: The flagger's directions
A flagger controls traffic through a work area that changes from day to day, and those instructions take precedence over the fixed signs and markings in that zone.
-
20. You are in a passing zone that continues over the crest of a hill ahead. May you start a pass?
Show answer
Answer B: Only if you can finish it well before the crest
Beyond the crest you cannot see oncoming traffic, so any part of the pass that happens there is being made blind.
