-
2. What makes a left turn protected rather than permissive?
Show answer
Answer B: Oncoming traffic is held by a red signal while you have a green arrow
A protected turn is one where the conflicting movements are stopped by their own signal, which is what the green arrow indicates.

3. You hear a bang and one of the front tires deflates while you are on the highway. What happens to the vehicle?
Show answer
Answer D: It pulls strongly toward the side that failed
The collapsed tire drags heavily on that corner, so the vehicle veers toward it. Hold the wheel firmly, keep your line and let the speed fall before leaving the road.
-
4. You are approaching a traffic light that has been green for a long time. How should you treat it?
Show answer
Answer C: Expect it to change and be ready to stop
A light that has been green for a while is called a stale green light. Cover the brake and decide in advance where you could still stop safely.
-
5. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
6. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?
Show answer
Answer D: Slow or stop and let the person reach safety
Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.
-
7. You are turning right on a red light where that is permitted. What does the law require first?
Show answer
Answer B: A full stop, then yielding to traffic and pedestrians
A right turn on red is allowed only after stopping completely and giving way to everyone who has the green, including people in the crosswalk.
-
8. You are traveling at 55 mph on a rural road and come up behind a horse-drawn buggy. What is the main danger?
Show answer
Answer D: You close on it very quickly because it moves at walking pace
A buggy travels only a few miles an hour, so the gap closes far faster than drivers expect and there is very little time to brake once you see it.
-
9. In near freezing weather, which part of an otherwise clear road is most likely to still be icy?
Show answer
Answer D: A shaded dip under trees or beside a rock cut
Sun clears most of the road, but shaded hollows never warm up and can hold ice long after the rest of the pavement is dry.
-
10. How many points does a conviction for failure to yield the right of way add to an Oklahoma driving record?
Show answer
Answer D: 2 points
Failure to yield the right of way is assessed 2 points under Oklahoma's mandatory point system.
-
11. What does it mean to scan the road while driving?
Show answer
Answer A: Moving your eyes constantly over the road, the sides and the mirrors
Scanning keeps information coming in from every direction, while a fixed stare leaves you blind to everything else.
-
12. Warning signs such as stop ahead, yield ahead and signal ahead are installed mainly where
Show answer
Answer B: the traffic control device cannot be seen from far enough away
These advance warning signs are used when a crest, curve or obstruction keeps the stop sign, yield sign or signal from coming into view in time for a driver to react.
-
13. Which statement about standard drinks is correct?
Show answer
Answer C: A standard serving of beer, of table wine and of distilled spirits each contain about the same amount of pure alcohol
Roughly 12 ounces of regular beer, 5 ounces of table wine and 1.5 ounces of 80 proof spirits each contain about the same amount of pure alcohol, so the type of drink does not change the effect.
-
14. Is it a good idea to shift into neutral and coast down a long hill to save fuel?
Show answer
Answer B: No, you lose engine braking and some control of the vehicle
In neutral the engine cannot help slow the vehicle, so the brakes do all the work and can overheat. Stay in gear so the drivetrain helps hold your speed.
-
15. The lights at a highway-rail grade crossing begin to flash red as you approach. What must you do?
Show answer
Answer B: Stop short of the tracks and wait until the lights stop and no train is near
Flashing red lights at a crossing require a stop clear of the tracks, and you may proceed only once the lights have stopped, any gates are fully raised and no train is approaching.
-
16. You are the second vehicle waiting to turn left on a green ball. Where should you wait?
Show answer
Answer A: Behind the stop line, until the first vehicle has actually turned
Only the lead vehicle should move into the intersection to wait; a second vehicle inside it is likely to be stranded there when the light changes.
-
17. A grade crossing is marked only with a crossbuck and has no lights or gates. What does the crossbuck require of you?
Show answer
Answer C: Yield to rail traffic and cross only when no train is approaching
The crossbuck requires road users to yield the right-of-way to rail traffic, so you must look and listen and be ready to stop.
-
18. Your light turns green, but a vehicle from the cross street is still finishing a turn inside the intersection. What should you do?
Show answer
Answer B: Wait until that vehicle has cleared the intersection
A green indication lets you proceed only after yielding to pedestrians in the crosswalk and to vehicles already lawfully within the intersection.
-
19. Which of these is announced with the same family of signs as the facility shown here?
Show answer
Answer A: A rest area for travelers
A rest area belongs to the same motorist service series, which points travelers toward facilities such as fuel, food, lodging and medical care.
-
20. In the code that governs pavement markings, what does a double line stand for?
Show answer
Answer B: A maximum restriction
The marking code is consistent: a double line means the strongest restriction, a solid line discourages or forbids crossing, and a broken line is permissive.
