1. What is the usual result of driving well above the flow of traffic on a typical trip?
Show answer
Answer B: Very little time saved, with much greater risk
Signals, traffic and short distances swallow the theoretical gain, while crash risk and crash severity both climb sharply with speed.
-
2. Before pulling out to pass on a two lane road, which lane position gives the best view of the road ahead?
Show answer
Answer B: The left portion of your lane
Moving to the left of your own lane lets you see past the vehicle ahead and judge the oncoming lane before committing any part of the machine to it.
-
3. You are leaving a freeway by an exit ramp. Where should you slow down?
Show answer
Answer D: On the ramp itself, after you have left the through lane
Braking in the through lane surprises the traffic behind, so the rider signals, moves onto the ramp and does the slowing in the space provided for it.
-
4. You are approaching an intersection in a line of traffic. What can you do to be more visible to a driver waiting to pull out?
Show answer
Answer D: Move to a lane position where you are not hidden behind the vehicle ahead
A motorcycle tucked directly behind a larger vehicle is invisible to a waiting driver until the moment it appears, so the rider moves to where the headlight can be seen.
-
5. On a divided highway you see a median opening marked for authorized vehicles only. May you use it to turn around?
Show answer
Answer D: No, those openings are for emergency and maintenance vehicles
Official crossovers are reserved for emergency and highway maintenance use; turning there puts a slow vehicle across high-speed traffic.
-
6. Is it acceptable to drive with your vehicle straddling the line between two lanes?
Show answer
Answer D: No, you must drive as nearly as practical entirely within a single lane
A vehicle astride the line takes up two lanes and leaves the drivers around it unable to predict where it will go.
-
7. How should a rider dress for a long ride in very hot weather?
Show answer
Answer C: In ventilated riding gear that still covers the arms and legs
Mesh and vented riding gear flows air while keeping its abrasion protection and shading the skin, so heat is not a reason to ride uncovered.
-
8. On a narrow residential street, why does parking tight against the curb matter so much?
Show answer
Answer C: Because fire trucks and ambulances need the width to get through
Cars parked even a foot out from the curb on both sides can narrow a street until a fire truck or ambulance cannot pass.
-
9. What should a pre-ride check of a belt final drive look for?
Show answer
Answer C: Correct tension, plus cracks, frayed edges and missing teeth
A belt is inspected for tension and for damage such as cracks, missing teeth and worn edges, and unlike a chain it is never lubricated.
-
10. A group in formation needs to change lanes. What is the safest way to do it?
Show answer
Answer A: The leader starts the change early enough for the whole group to complete it
Beginning the change early gives the entire formation the road and the time it needs to move over together instead of scattering across two lanes.
-
11. What is the safest way to deal with the situation this sign announces?
Show answer
Answer B: Match the speed of the other traffic stream and open a gap so vehicles can blend without hard braking
Blending works when speeds are matched and gaps are opened, so nobody has to brake hard or swerve where the two streams come together.
-
12. The sign over the leftmost lane reads LEFT LANE MUST TURN LEFT. You are in that lane and want to go straight. What should you do?
Show answer
Answer C: Move out of the lane before the intersection if it is safe
A mandatory movement lane control sign makes the turn compulsory for that lane, so a driver who wants another movement must change lanes in advance.
-
13. You are approaching a sharp curve. When should you reduce your speed?
Show answer
Answer D: Before you enter the curve, so you can accelerate gently through it
Braking hard inside a curve uses up the traction that is already being demanded for cornering, so the slowing must be finished before you enter.
-
14. What should the operator do while a passenger climbs on board?
Show answer
Answer D: Sit on the machine with both feet planted and the front brake held on
The added weight arrives suddenly and off center, so the operator braces the motorcycle with both feet down and the front brake applied to keep it still.
-
15. 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.
-
16. Below a speed limit sign is a smaller panel with white numbers on a black background and the word NIGHT. What does it show?
Show answer
Answer D: The limit that applies after dark
A night speed limit panel sets a separate legal maximum for the hours of darkness, and its reversed colors mark it as the night figure.
-
17. You are turning left at an intersection and an oncoming bicyclist is approaching in the bike lane. What must you do?
Show answer
Answer B: Yield and complete the turn only after the bicyclist has passed
A bicycle in the roadway has the same right of way as a vehicle, so a left-turning driver must yield to an oncoming rider just as to an oncoming car.
-
18. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
19. You are about to pass a long tractor-trailer on a two-lane road. What should you expect?
Show answer
Answer B: You will need more clear road, since the vehicle is much longer
A tractor-trailer can be 70 feet long, so passing it takes more distance and more time than passing a car at the same speed difference.
-
20. Before making a right turn at an intersection, what should you check besides oncoming traffic?
Show answer
Answer B: Your right blind spot and the crosswalk, for cyclists and pedestrians
Right turns often catch a cyclist or a pedestrian coming up on the right, so check the blind spot and the crosswalk before you turn.
-
21. Which items belong to the Controls step of the T-CLOCS inspection?
Show answer
Answer D: Handlebars, levers, cables, hoses and the throttle
The Controls step covers everything the rider operates by hand or foot, plus the cables and hoses that carry those inputs to the machine.
-
22. 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.
-
23. You are waiting to turn and the traffic ahead has stopped. Where must you not come to rest?
Show answer
Answer D: On the crosswalk, which people need in order to cross the street
Stopping on a crosswalk forces pedestrians out into the traffic lanes to get around you, so you hold back before it instead.
-
24. 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.
-
25. A motorcycle in your group develops a mechanical problem on a busy highway. What is the best response?
Show answer
Answer C: Signal the group off at the next exit or wide, safe pull off area
A narrow shoulder beside fast traffic is a dangerous place to gather, so the group moves on to a spot where every machine is well clear of the roadway.
