1. You are turning left at an intersection and an oncoming bicyclist is approaching in the bike lane. What must you do?
Show answer
Answer B: Yield and complete the turn only after the bicyclist has passed
A bicycle in the roadway has the same right of way as a vehicle, so a left-turning driver must yield to an oncoming rider just as to an oncoming car.
-
2. When is a driver at the highest risk of falling asleep at the wheel?
Show answer
Answer B: Late at night, early morning and mid afternoon
The body clock produces its deepest dips in alertness in the small hours and again in the middle of the afternoon, and crash records follow those dips.
-
3. You must leave your vehicle beside a narrow rural road at night. What should you do?
Show answer
Answer B: Get it right off the pavement and switch on the hazard lights
A vehicle left on an unlit rural road is very hard to see, so move it completely clear of the traveled surface and mark it with the hazard lights.
-
4. An overhead lane signal shows a flashing yellow X above your lane. What does it mean?
Show answer
Answer D: The lane may be used only for a left turn
A flashing yellow X marks a lane that may be used only to make a left turn; a steady yellow X is the one that warns you to leave the lane.

5. How does an Oklahoma speeding fine change in a school or construction zone when workers or equipment are present?
Show answer
Answer C: It doubles
Oklahoma doubles speeding fines in school and construction zones when workers or equipment are present.
-
6. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
7. How can you keep space at the sides of your vehicle in heavy traffic?
Show answer
Answer D: Drive in the gaps between the other vehicles rather than beside them
Travelling in the open spaces rather than alongside others keeps a way out open on at least one side.
-
8. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
-
9. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
10. A school bus ahead of you has its red lights flashing and its stop arm extended. What are you required to do?
Show answer
Answer A: Stop and stay stopped until the lights stop flashing and the bus starts moving
Flashing red lights and an extended stop arm mean children are getting on or off, so traffic must stop and wait until the bus withdraws the signals and moves again.
-
11. Two roads come together at a shallow angle under a MERGE sign, with no yield line on either one. What is expected of you?
Show answer
Answer D: Adjust your speed and position so you blend smoothly into the other traffic
A merge means neither road ends at a stop; drivers adjust speed and position so that the two streams fit together without stopping.
-
12. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
13. The lane you are in is marked with a straight arrow and a right-turn arrow together. What does that mean?
Show answer
Answer D: Drivers in that lane may either go straight or turn right
A lane marked with two arrows serves both movements, so a driver in it may take either one.
-
14. The added lane warning sign tells a driver that
Show answer
Answer A: an extra lane begins ahead, so entering traffic does not have to merge into an existing lane
Where a lane is added, traffic entering the roadway gets a lane of its own, so merging is not required, although drivers should still watch the vehicles beside them.
-
15. A freeway sign shows a minimum speed limit. What does it require?
Show answer
Answer B: That you keep up with it unless conditions make that unsafe
A minimum speed limit keeps very slow vehicles off the highway, but weather, traffic or a mechanical problem may make a lower speed necessary and lawful.
-
16. May you park at the curb immediately next to a railroad crossing?
Show answer
Answer A: No, you must leave the crossing and its approach clear
Parking beside a crossing hides the tracks and the signals from approaching drivers and leaves no room for a vehicle that has to clear the rails.
-
17. You are already inside an intersection when you realize you should be in the lane beside you. What should you do?
Show answer
Answer C: Stay in your lane through the intersection and change lanes afterwards
Drivers in an intersection are watching for cross traffic and turning vehicles, so an unexpected sideways move there is easily missed.
-
18. You are driving slower than the general flow on a multilane highway. Which lane should you use?
Show answer
Answer D: The right lane, keeping the left lanes free for faster traffic and passing
Slower traffic must keep right so that faster vehicles and overtaking traffic can use the left lanes without weaving between lanes.
-
19. A white regulatory sign shows the silhouette of a truck inside a red circle with a diagonal slash. What does it mean?
Show answer
Answer A: Trucks are not allowed to use that road
The circle and slash over a symbol always means the movement or vehicle shown is prohibited, so trucks must keep off that roadway.
-
20. How should a head restraint be adjusted?
Show answer
Answer D: So the top is at least as high as the back of your head and close behind it
A restraint set at head height and close behind limits how far the head snaps backward in a rear impact, which is what reduces neck injury.
