1. 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.
-

3. Why should pant legs be secured and bootlaces tucked away?
Show answer
Answer A: Loose fabric and laces can tangle in the chain, the controls or a wheel
Anything hanging near the moving parts of a motorcycle can be caught and pulled in, which can trap a foot or lock the rear wheel.
-
4. What is the safest way to pass a bicyclist on a road with two lanes going your way?
Show answer
Answer D: Change lanes completely, as you would for a car
A bicycle is entitled to the room a vehicle needs, and moving into the next lane gives the rider space to swerve around a drain or a pothole.
-
5. Why should a rider avoid coasting to a stop with the transmission in neutral?
Show answer
Answer C: Engine braking is lost and so is the ability to accelerate out of trouble
Staying in gear keeps engine braking working and leaves the rider able to power away from a hazard instead of hunting for a gear first.
-
6. A deer crosses the road in front of you and disappears into the trees. What should you expect?
Show answer
Answer B: That other deer are likely to follow it across the very same stretch of road
Deer usually move in groups, so one crossing the road is a warning that more may follow.
-
7. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
8. Where is reflective material most effective at attracting a driver's attention at night?
Show answer
Answer A: On the arms, legs and helmet, where the movement draws the eye
Reflective patches that move as the rider rides are noticed sooner than static ones, and a helmet sits high where drivers are already looking.
-
9. Which of these would appear as a symbol on a blue general service sign?

Answer A: A hospital
General service signs cover facilities such as hospitals, fuel, food, lodging, camping, telephones and rest areas, all shown in white on blue.
-
10. A vehicle is sitting in your blind spot and you need to change into that lane. What should you do?
Show answer
Answer B: Adjust your speed to open a clear gap, then check again and move over
Changing your speed either drops the other vehicle behind you or lets it move ahead, which turns the blind spot back into open space.
-
11. On a long uphill grade a second lane opens on the right and a sign directs slower traffic into it. You are towing a trailer and holding up a line of vehicles. What should you do?
Show answer
Answer A: Move into the right-hand lane and let the faster traffic use the left lane
A climbing lane exists so that slow vehicles can be passed safely, and the slower vehicle is the one that belongs in it.
-
12. A driver moves into the space you were keeping ahead of you. What should you do?
Show answer
Answer D: Ease off and rebuild the gap in front of you
Losing a following gap is common in traffic; the answer is simply to drop back and recreate it rather than drive too close.
-
13. You are turning left at an intersection just beyond the crest of a hill. What is the added risk?
Show answer
Answer B: Oncoming vehicles appear with very little warning and close quickly
A crest hides approaching traffic until it is close, so the gap you thought was empty can fill in the time the turn takes.
-
14. What do the grooves in a tire tread do on a flooded road surface?
Show answer
Answer B: They give the water a way to escape so the tread can touch the road
Tread grooves pump water out from under the tire so rubber can meet pavement. A worn tread moves less water, so hydroplaning starts sooner.
-
15. You are about to pass a bicyclist on a narrow two-lane road. What is the correct way to do it?
Show answer
Answer A: Wait for a clear gap and move well left, giving the rider wide space
Pass a cyclist as you would a car: wait for clear road, change lane position to leave generous clearance, and return only when the rider is well behind you.
-
16. What offense does an Illinois vehicle owner commit by knowingly allowing someone who is visibly incapable of driving safely due to intoxication to operate their vehicle?
Show answer
Answer B: A Class A misdemeanor, punishable by up to a year in jail and a fine of up to $2,500
Illinois makes it a Class A misdemeanor, punishable by up to one year in jail and a fine of up to $2,500, to knowingly permit an intoxicated or otherwise incapable person to drive one's vehicle.
-
17. What should a passenger do when the motorcycle leans into a curve?
Show answer
Answer A: Lean with the operator, staying directly behind them
A passenger who leans with the operator lets the motorcycle follow its natural line, while leaning against the lean fights the operator's control inputs.
-
18. 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.
-
19. A sign with a green background and a white legend normally provides
Show answer
Answer A: directions, distances and destinations
Green is the background color of the guide sign series, which names routes and destinations and gives the distance to them.
-
20. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
21. Which quality matters most in a face shield?
Show answer
Answer B: It resists penetration and is free of deep scratches
A shield has to stop objects thrown up from the road and stay clear enough for undistorted vision, and it needs some airflow so that it does not fog.
-
22. How does weight transfer during braking change what each brake can do?
Show answer
Answer A: Weight moves forward, so the front tire grips harder and the rear grips less
Deceleration pitches the machine forward onto the front wheel, which is why the front brake supplies most of the stopping power and the rear locks easily.
-
23. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
24. A yellow diamond shows two lanes narrowing into one. What does it require of a driver?
Show answer
Answer D: Adjusting speed and merging before the lane disappears
The lane ends sign gives notice that one lane will be dropped, so drivers should adjust speed and blend into the continuing lane in good time.
-
25. With the chin strap fastened, how can you check that a helmet is the right size?
Show answer
Answer A: Try to roll it forward off your head, since a good fit will not come off
The roll off test shows whether the helmet will stay on in a crash. If it can be rolled off the front of your head with the strap done up, it is too big.
