1. Why is a sign reading BRIDGE ICES BEFORE ROAD worth heeding even when the road itself is merely wet?
Show answer
Answer C: Cold air passes under a bridge as well as over it
A bridge deck loses heat from below as well as above, so it can be frozen while the road on either side of it is only wet.
-
2. What is threshold braking?
Show answer
Answer C: Braking hard but staying just short of locking the wheels
A rolling tire grips better than a sliding one, so the shortest stop comes from pressure held just below the point where the wheels lock.
-
3. What is worth carrying in the vehicle during a winter trip?
Show answer
Answer A: A blanket, a flashlight, a scraper and a small shovel
A winter kit keeps you warm and visible if you are stopped for hours, and lets you clear glass and dig the wheels out. Hot water can crack cold glass.
-
4. Why should you make sure your turn signal has stopped flashing after a lane change?
Show answer
Answer A: A signal left flashing tells other drivers that you intend to move again
Other drivers act on your signals, so one that is left on gives them false information about what you are about to do.
-
5. No plaque stating days or hours accompanies this sign at the intersection. When does the restriction apply?
Show answer
Answer D: At all times, since nothing limits it to particular periods
A regulatory restriction runs continuously unless a supplemental plaque states the days or hours during which it applies.
-
6. You are approaching a horse and rider on a country road. What about your horn?
Show answer
Answer C: Do not sound it at all, because the noise can frighten the animal
A startled horse is dangerous to its rider and to you, so pass wide and slow and leave the horn alone.
-
7. You are turning right where a paved trail crosses the road just past the corner. What should you look for?
Show answer
Answer B: Cyclists and walkers arriving from either direction on the trail
A shared use path carries two-way traffic on foot and on bicycles, so scan both directions along the trail before crossing it.
-
8. In Oklahoma, an applicant 18 or older who passes the written test and chooses to skip the learner permit stage may take the driving test how soon?
Show answer
Answer A: As early as the next business day
An applicant 18 or older who goes straight from the written test to a Class D license may take the driving test as early as the next business day, rather than holding a learner permit first.
-
9. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
-
10. You are passing a large truck on an open highway in a strong crosswind. What should you expect?
Show answer
Answer A: A push toward the truck, then a push the other way as you clear it
The truck shelters you as you go by and then releases you into the full gust, so the load on the steering changes twice during the pass.
-
11. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
12. A steady green arrow pointing left is displayed for your turning lane. What does it tell you?
Show answer
Answer D: The turn is protected because conflicting traffic is being held
A steady green arrow gives a protected movement in the direction shown, although you still yield to pedestrians and to any vehicle already inside the intersection.
-
13. You are entering a marked work zone. What should you expect?
Show answer
Answer B: A reduced posted speed, narrowed or shifted lanes, and traffic that may stop suddenly
Work zones change the geometry of the road and can bring traffic to a halt without warning, so the posted work zone speed and increased following distance both apply.
-
14. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
15. Blue pavement markings are used together with white markings at
Show answer
Answer D: parking spaces reserved for people with disabilities
Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.
-
16. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
17. You notice that the driver ahead of you is holding a phone to the ear. What should you do?
Show answer
Answer C: Assume slower reactions and leave extra space, or else hold back
A driver on the phone reacts late and misses things, so the safe response is distance rather than a lesson.
-
18. A NO LEFT TURN sign carries a plaque reading 7 AM TO 9 AM MON TO FRI. What does the assembly mean?
Show answer
Answer A: The turn is banned only during those hours on those days
A time plaque limits the restriction to the periods shown, so outside those hours and days the left turn may be made normally.
-
19. You are stopped at a T-intersection and a driver on the through road is signaling a right turn into your road. What is the safe assumption?
Show answer
Answer B: The driver may not actually turn, so wait until the vehicle slows and starts turning
A blinking signal may have been left on by mistake or may be for the next street, so wait until the vehicle actually slows and turns.

20. How many points does a careless driving conviction add to an Oklahoma driving record?
