1. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
-
2. You are about to pass another vehicle at night with your high beams on. What should you do?
Show answer
Answer C: Switch to low beams as you come up behind it and while you are alongside
High beams shining into the mirrors of the vehicle ahead blind the very driver whose reaction you depend on during the pass.
-
3. What must a driver be ready for beyond this sign?
Show answer
Answer C: Vehicles approaching from the opposite direction in the next lane over
The separation between the two directions runs out, so from that point oncoming vehicles share the same pavement and the driver has to keep right.
-
4. At an intersection where every approach carries this sign, two drivers arrive at exactly the same instant. Which of them goes first?
Show answer
Answer C: The driver on the right
Order of arrival decides who goes first, and when two vehicles arrive together the driver on the right proceeds while the other gives way.
-
5. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.
-
6. What does a yield sign require of a driver?
Show answer
Answer A: Slow down, and stop when necessary, so conflicting traffic can go first
A yield sign obliges the driver to reduce to a speed suited to conditions and to stop when needed so that conflicting traffic or pedestrians are not interfered with.
-
7. Before making a U-turn on a narrow street, what should the rider do first?
Show answer
Answer A: Check that the street is wide enough and clear in both directions
A U-turn commits the rider to crossing both directions of traffic in a space the machine may not fit into, so both the width and the traffic are judged before starting.
-
8. On the Interstate system, what do the odd-numbered one and two digit routes have in common?
Show answer
Answer D: They run mainly north and south
Odd numbers are given to north and south Interstates and even numbers to east and west ones, with the numbers rising toward the north and the east.
-
9. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.

Nebraska defines road assistance vehicles to include Department of Transportation vehicles, State Patrol motorist assistance vehicles, registered towing or roadside assistance vehicles and utility service vehicles.
-
11. Why should a rider avoid painting a helmet or cleaning it with strong solvents?
Show answer
Answer D: Chemicals can weaken the shell and the liner without showing it
Solvents and some paints attack the shell and the foam, so use mild soap and water and follow the maker's instructions to keep the helmet's protection intact.
-
12. Why is it dangerous to make a left turn from the second lane from the center?
Show answer
Answer C: Because a driver in the lane beside you is turning into the same space
Drivers in the proper turn lane are entitled to that space, and turning across them puts two vehicles into one path through the intersection.
-
13. What is wrong with riding in sneakers or sandals?
Show answer
Answer D: They come off, expose the foot and give no protection in a fall
Light footwear tears away or comes off in a crash and offers no abrasion or crush protection for the foot and ankle.
-
14. 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.
-
15. A set of reversible express lanes is closed off with gates and signs while it runs the other way. What must you never do?
Show answer
Answer C: Enter past a closed gate or a sign showing the lanes are closed
When reversible lanes are closed they may already be carrying traffic in the opposite direction, so entering past a gate can put you head-on into that traffic.
-
16. How long is the temporary license valid after a Nebraska officer confiscates a license for a failed or refused test?
Show answer
Answer D: 15 days
The temporary license issued under the administrative license revocation law expires fifteen days after it is issued, and the revocation then begins.
-
17. Which of these makes you unpredictable to other drivers?
Show answer
Answer B: Changing lanes suddenly without signaling, to save a moment
An unsignalled, sudden lane change gives nobody time to react and is a common cause of sideswipe collisions.
-
18. There is a stop sign but no stop line and no crosswalk. Where must you stop?
Show answer
Answer A: Before entering the intersection, where you can see cross traffic
With no line or crosswalk, stop before you enter the intersection at the point where you can see traffic on the cross street.
-
19. 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.
-
20. Why do experienced riders cover the clutch lever and the brake lever in heavy traffic?
Show answer
Answer B: It shortens the time needed to react if they suddenly have to stop
With fingers already resting on the levers the rider skips the time it takes to reach for them, which shortens overall stopping distance.
-
21. What should a passenger be told about moving around on the motorcycle?
Show answer
Answer A: To stay directly behind the operator and avoid sudden or unnecessary movement
Unexpected movement by a passenger upsets the balance of the machine, most of all at low speed and while the motorcycle is leaned over in a turn.
-
22. Which of the four blind spots around a tractor-trailer is the largest?
Show answer
Answer A: The one on the right side of the truck
A truck has no-zones on all four sides, and the right-side blind spot is the largest because it runs back along the trailer and reaches across more than one lane.
-
23. A sign with a brown background and a white legend guides road users to
Show answer
Answer B: parks, campgrounds and other recreational or cultural sites
Brown is reserved for recreational and cultural interest area signing, such as parks, historic sites and scenic areas.
-
24. A rectangular red sign with the white words WRONG WAY means that
Show answer
Answer C: the driver is already traveling against the legal flow and must not continue
The wrong way sign uses a white legend and border on red and addresses a driver who has entered a ramp or one-way roadway in the wrong direction, who should stop and turn around safely.
-
25. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
