1. You leave your car so that its rear overhangs a marked crosswalk. What is wrong with that?
Show answer
Answer B: Pedestrians must step around it into the traffic lane
A crosswalk has to stay completely clear; anything sticking into it pushes people on foot out into the path of moving vehicles.
-
2. What does a flashing yellow traffic light mean?
Show answer
Answer B: Slow down and proceed with caution
A flashing yellow lets you enter the intersection cautiously after yielding to pedestrians and to conflicting traffic that is already there.

3. You feel dizzy and get a headache while driving with the windows closed. What could be the cause and what should you do?
Show answer
Answer D: An exhaust leak letting carbon monoxide into the cabin, so open the windows and stop to get fresh air
Carbon monoxide is colorless and odorless, and headache, dizziness and drowsiness are early signs. Get fresh air at once and have the exhaust system inspected.
-
4. You enter a work zone at night where one lane is closed and a flagger is on duty. What is the safest approach?
Show answer
Answer A: Slow early, merge before the closure and be ready to stop
Merging early at a reduced speed keeps the queue orderly and leaves you room to stop for equipment, workers or traffic that has halted ahead.
-
5. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
6. What does a tire with worn tread do on a wet road?
Show answer
Answer B: It loses grip and it hydroplanes at a lower speed than a good tire
Tread grooves carry water away from the contact patch, and a worn tire cannot do that, so it floats on the water sooner.
-
7. A barricade carries a sign reading ROAD CLOSED TO THROUGH TRAFFIC. What does it permit?
Show answer
Answer B: Local access for people whose destination is on that road
This closure keeps out drivers who are only passing through while still allowing residents and deliveries to reach addresses within the closed section.
-
8. Besides its height, what else matters about a head restraint?
Show answer
Answer C: That it is close to the back of the head, and not far behind it
A restraint that sits far behind the head lets the head snap back before it is caught, so a small gap is important.
-
9. How does the application fee for renewing an Oklahoma Class D license differ for an applicant age 65 or older?
Show answer
Answer B: It is waived, while the license fee itself still applies
Service Oklahoma's fee schedule lists no application fee for a Class D license renewal at age 65 or older, while a younger applicant pays a small application fee in addition to the license fee.
-
10. Your headlights suddenly go out while you are driving at night. What should you do?
Show answer
Answer A: Try the dimmer switch and the headlight switch, turn on the hazard lights and pull off the road
Switching between high and low beams or cycling the light switch sometimes restores the lights. If not, use the hazard and parking lights to get off the road safely.
-
11. A deer crosses the road in front of you and disappears into the trees. What should you expect?
Show answer
Answer B: That other deer are likely to follow it across the very same stretch of road
Deer usually move in groups, so one crossing the road is a warning that more may follow.
-
12. Why is being predictable an important part of driving safely?
Show answer
Answer A: Because other road users are able to plan around what you are doing
Other drivers make their decisions from what they expect you to do, so surprises are what produce collisions.
-
13. On a regulatory sign, what does a red circle with a diagonal slash drawn over a symbol mean?
Show answer
Answer D: The movement or action shown by the symbol is prohibited
A red circle with a diagonal slash is the standard way of showing that the movement pictured inside it, such as a U-turn or a right turn, is not allowed.
-
14. In a vehicle with automatic transmission, which foot should operate the brake and accelerator?
Show answer
Answer D: The right foot for both pedals
Using only the right foot prevents pressing both pedals at once and keeps the response the same in every vehicle you drive. The left foot rests on the floor or the footrest.
-
15. The stability control warning light flashes while you are driving through a curve. What does it mean?
Show answer
Answer A: The system is actively working to keep the vehicle under control, so slow down
A flashing stability control light means the system is braking individual wheels because you are near the limit of grip. Ease off and drive more gently.
-
16. You are on an entrance ramp joining a busy freeway. What should you do with your speed in the acceleration lane?
Show answer
Answer D: Build it up to about the speed of the traffic you are joining
Merging works when your speed matches the traffic stream, because a large speed difference forces the drivers already on the freeway to brake or swerve.
-
17. A driver passes this sign on an open road. Over what stretch does the figure it sets stay in force?
Show answer
Answer A: From the sign onward, in every lane, until another sign sets a different figure
The figure governs the road from the sign onward and binds every lane, and it stays in force until a later sign sets a different one.
-
18. Which color scheme is standard for the drums and barricades that channel traffic through a work zone?
Show answer
Answer C: Alternating orange and white retroreflective stripes
Drums and barricades carry alternating orange and white retroreflective stripes, and the traffic cones used in the same zones are predominantly orange.
-
19. Your brake pedal sinks to the floor and the vehicle does not slow down. What is a reasonable sequence of actions?
Show answer
Answer C: Pump the pedal, shift to a lower gear and apply the parking brake gradually while steering to a safe spot
Pumping can rebuild pressure in a partly failed system, a lower gear adds engine braking, and easing on the parking brake slows the vehicle without locking the wheels.
-
20. A loaded truck is coming up an entrance ramp as you approach in the right lane of the freeway. What is the most helpful action?
Show answer
Answer A: Adjust your speed to open a gap for it
A heavy vehicle accelerates slowly, so opening a gap or moving over costs you seconds and saves the truck driver from being forced to stop on the ramp.
