1. At a four-way stop another driver pulls out ahead of you when it was clearly your turn. What is the correct response?
Show answer
Answer B: Let that driver go through, then take your turn when the way is clear again
Right of way is something you give, never something you take, so yielding to a driver who takes it wrongly avoids a crash you would otherwise share.
-
2. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
3. What is the correct relationship between air bags and seat belts?
Show answer
Answer B: Air bags are designed to work together with seat belts, not instead of them
An air bag is a supplemental restraint that cushions one impact, while the belt keeps you in position so the bag can work and protects you in rollovers and secondary impacts.
-
4. You see brake lights several vehicles ahead of you in your lane. What is the best first step?
Show answer
Answer C: Ease off the gas and cover the brake pedal
Reacting to the trouble several vehicles ahead, rather than waiting for the car in front, cuts your reaction time and warns the driver behind you.
-
5. You come back to find that your parked car has rolled out into the street. What most likely went wrong?
Show answer
Answer C: The parking brake was not set and the wheels were not turned
The parking brake, a gear or park, and turned front wheels are three separate safeguards, and a runaway means at least the first two were missing.
-
6. You are stopped at a stop sign where your road ends at a two-way through street and you plan to turn left. What must you yield to?
Show answer
Answer B: Traffic from both directions and any pedestrians crossing
A left turn from the stem of a T crosses the near lane and joins the far one, so you give way to traffic in both directions and to pedestrians.
-
7. When does an Oklahoma driver NOT have to stop for a school bus with its red lights flashing?
Show answer
Answer C: When the bus is on a different roadway, or in a no-pedestrian loading zone
Oklahoma excuses a driver from stopping for a school bus when the bus is on a different roadway, or when it is stopped in a loading zone accessed by a controlled-access highway where pedestrians are not allowed to cross.
-
8. You are stopped at a red light waiting to turn right where the turn is allowed. Besides traffic from the left, what must you check?
Show answer
Answer D: Both crosswalks, and anyone approaching along your right side
A right turn on red crosses the crosswalk in front of you and enters the one on the cross street, and cyclists often approach along your right.
-
9. May you stop in the striped triangle that separates an exit ramp from the freeway lanes?
Show answer
Answer A: No, it is not a lane and stopping there is dangerous
The striped gore area is not a travel lane or a shoulder, and a vehicle stopped there sits directly in the path of drivers correcting a late exit.
-
10. When required to stop for an approaching train, within what distance of the nearest rail must an Oklahoma driver stop?
Show answer
Answer D: Within 50 feet but not less than 15 feet
Oklahoma law requires a driver approaching a railroad grade crossing under specified warning conditions to stop within 50 feet but not less than 15 feet from the nearest rail.
-
11. A child in the back seat unfastens a seat belt while you are on the freeway. What should you do?
Show answer
Answer A: Pull off safely and refasten the belt
Turning or reaching back takes your eyes and hands off a high speed task, so leave the freeway or use the shoulder only if there is no exit, then fix the belt.
-
12. A sign on a long descent points to a RUNAWAY TRUCK RAMP a mile ahead. What is that ramp for?
Show answer
Answer C: Stopping a vehicle whose brakes have failed
An escape ramp climbs into deep gravel or sand to bring a vehicle with failed brakes to a halt, so no one should stop or park in it.
-
13. Yellow signs each showing one large black arrowhead, installed in a row along the outside of a curve, are
Show answer
Answer D: chevron alignment signs marking the change of direction of the curve
Chevron alignment signs are placed on the outside of a curve so that several are in view at once, letting the driver judge how sharply the road turns.
-
14. When are you expected to switch from high beams to low beams?
Show answer
Answer D: When a vehicle approaches from ahead or you come up behind another vehicle
High beams blind other drivers, both those coming toward you and those you follow through their mirrors. Dim them whenever another vehicle is within range.
-
15. You have just passed a vehicle on a two-lane road. When may you return to your lane?
Show answer
Answer B: When you can see the whole vehicle in your inside mirror
Seeing the entire vehicle you passed in your rearview mirror shows there is room to pull back in without cutting it off.
-
16. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?
Show answer
Answer B: Obstruction of the normal flow of traffic, which is prohibited in itself
Driving so slowly that other traffic is impeded is an offense in its own right when nothing about safety, weather or the road calls for it.
-
17. A large truck ahead of you in a roundabout is using part of both lanes as it goes around. What is the correct response?
Show answer
Answer B: Stay back and give it room until it leaves the roundabout
Long vehicles need extra width to get around the central island, so drivers behind must hold back rather than share the space beside them.
-
18. Why do many crashes happen on routes the driver knows very well?
Show answer
Answer D: Familiar roads let attention slip into routine
When a route is automatic the mind wanders and hazards get missed, which is why a well known road deserves the same attention as a strange one.
-
19. Some crosswalks are marked with two transverse lines and others with a row of wide bars laid along the direction of travel. Why is the second pattern used?
Show answer
Answer B: It is far easier for an approaching driver to see
Longitudinal bar patterns are used where extra visibility is wanted, such as an uncontrolled crossing or one near a school, because they show up much better from a car.
-
20. You are traveling at 55 mph and see a vehicle ahead moving at about 15 mph. What is the hazard?
Show answer
Answer A: You reach it far sooner than you expect
At a 40 mph difference you cover the gap in a few seconds, which is why drivers strike slow vehicles they saw in plenty of time.
