1. You have begun to move into the next lane when the gap you were aiming for closes. What is the safest action?
Show answer
Answer C: Return to your own lane, cancel the signal and wait for a better gap
An unfinished lane change leaves you in a space that no longer exists, and the lane you came from is still yours.
-
2. What alcohol level places a driver under 21 in violation of Oklahoma's zero tolerance law?
Show answer
Answer A: Any measurable quantity of alcohol in the blood or breath
Oklahoma's zero tolerance law makes it unlawful for anyone under 21 to drive or be in actual physical control of a vehicle with any measurable quantity of alcohol in the blood or breath.

3. 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.
-
4. At which location is this sign normally installed?
Show answer
Answer D: Facing traffic that could turn into a one-way roadway or ramp against the flow
It is posted where a driver could otherwise enter a ramp or a one-way roadway from the wrong end, so it faces exactly the traffic that has to be kept out.
-
5. While you wait for the ambulance at a crash, what is the most useful help you can give?
Show answer
Answer C: Keep the person still and warm, and press down firmly on any heavy bleeding
Keeping an injured person still and warm and controlling bleeding are among the few things a bystander can safely do.
-
6. You are waiting to pull out of a driveway when a bicyclist comes along the bike lane in front of you. What must you do?
Show answer
Answer D: Wait until the bicyclist has gone past
A driver leaving a driveway yields to everything already on the road, and a bike lane is part of the roadway.
-
7. Just before the front wheel reaches an obstacle, what should you do with the throttle?
Show answer
Answer C: Roll it on slightly to lighten the front end
A small amount of throttle shifts weight rearward and lightens the front wheel so it rides over the obstacle more easily.
-
8. Which rough check suggests that a helmet is a novelty shell rather than a certified helmet?
Show answer
Answer C: It weighs about a pound, far less than a certified helmet
A certified helmet weighs roughly three pounds because of its shell and thick liner, while a novelty shell is very light. Weight is only a clue, and the certification label is the real check.
-
9. In a work zone the temporary lane lines conflict with the old lines still visible on the pavement. Which do you follow?
Show answer
Answer C: The temporary markings, which show the current traffic pattern
Temporary markings define the traffic pattern in force, and the old lines are simply the layout that no longer applies.
-
10. What blood alcohol concentration makes an Oklahoma offense an aggravated DUI?
Show answer
Answer C: 0.15 or more
Oklahoma treats a DUI conviction with a blood or breath alcohol concentration of 0.15 or more as aggravated driving under the influence, which carries heavier penalties and an ignition interlock requirement.
-
11. The crossing gates begin to lower while your vehicle is still on the railroad tracks. What should you do?
Show answer
Answer B: Keep going forward and push through the gate if it should block your way
Gates are made to break away, and driving forward off the tracks is far safer than staying between them or backing up.
-
12. A car is waiting at a side street to pull out as you approach the intersection. What speed adjustment helps most?
Show answer
Answer B: Slow enough that you could still stop before reaching the intersection
Covering the brakes and reducing speed turns a possible collision into a stop the rider can actually make if the driver moves out.
-
13. When should you arrange your way home if you plan to drink?
Show answer
Answer C: Before the first drink
Judgment is the first thing alcohol weakens, so the plan has to be made while you can still make a good one.
-
14. You signaled a lane change and the signal did not switch itself off afterwards. Why does that matter?
Show answer
Answer B: Other drivers may act on a turn you do not intend to make
A signal left on tells other drivers you are about to turn, and someone may pull out in front of you. Cancel it as soon as the maneuver is finished.
-
15. A police officer in the intersection raises a hand toward you although your signal is green. What should you do?
Show answer
Answer B: Stop and wait for the officer to wave you on
An officer directing traffic overrides signals and signs, and drivers must follow the officer even when the light says otherwise.
-
16. How long must an Oklahoma driver keep an ignition interlock device installed after an additional DUI conviction beyond a second offense?
Show answer
Answer D: 5 years
Additional DUI convictions beyond a second offense require an Oklahoma driver to keep an ignition interlock device installed for 5 years, the longest period on the escalating scale.
-
17. Why is this restriction used so often on a divided road just before a crest or a bend?
Show answer
Answer A: Because a vehicle turning across the median there stays hidden from approaching drivers until it is too late
The maneuver needs a long gap and good visibility, and where sight distance is short an approaching driver has no time to react to a vehicle turning across the road.
-
18. You have shut the engine off with the kill switch because the throttle stuck open. What comes next?
Show answer
Answer D: Keep the clutch in, brake to a stop off the road, and find the cause
With the engine off and the clutch pulled in the motorcycle is only coasting, so brake to a stop clear of traffic and inspect the throttle cable and grip before restarting.
-
19. When must a passenger keep both feet on the footrests?
Show answer
Answer C: At all times, including while the motorcycle is stopped
Feet stay on the footrests even at a stop, because a foot put down or swung out can unbalance the motorcycle or be caught by the road.
-
20. How should a rider approach a curve whose radius keeps tightening the further you go into it?
Show answer
Answer A: Enter more slowly than the curve first appears to need, saving lean for the exit
In a decreasing radius curve the sharpest part comes last, so a slower entry leaves both speed and lean angle in reserve for where they are needed.
