1. In T-CLOCS, what does the letter O stand for?
Show answer
Answer B: Oil and other fluid levels
The O step covers engine oil, along with coolant, hydraulic brake fluid and any final drive fluid, plus a look underneath for leaks.
-
2. A flashing red arrow is displayed for your turning lane. What does it require?
Show answer
Answer D: Stopping, then turning when the way is clear
A flashing red arrow is treated like a stop sign for that movement: come to a full stop, then turn when it is safe and no one has to be cut off.
-
3. A motorcycle ahead of you is weaving slightly as it crosses a stretch of grooved pavement. What should you do?
Show answer
Answer D: Give the rider extra room until the surface improves
Grooves, metal plates and loose material affect a motorcycle far more than a car, so back off and let the rider deal with the surface.
-
4. A driver passes this sign on an entrance ramp while merging onto a freeway. Who has priority?
Show answer
Answer B: The traffic already traveling on the freeway
The sign places the duty on the entering driver, who must adjust speed and fit into a gap without forcing through traffic to brake or swerve.
-
5. Another driver takes a right of way that was legally yours. What should you do?
Show answer
Answer A: Give way to the other driver and avoid the crash, whatever the law says
Right of way is something you give, not something you take, and being in the right is no protection in a collision.
-
6. A piece of farm machinery ahead of you is wider than its own lane. What should you do?
Show answer
Answer C: Hold back until you can see far enough to pass safely
Wide equipment leaves no gap inside the lane and may use part of the other side, so a pass needs a long clear view of the road ahead.
-
7. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with turn arrows painted inside it. What is that lane for?
Show answer
Answer C: Left turns made by traffic traveling in either direction
That marking pattern identifies a two-way left-turn lane, which drivers approaching from both directions may use to prepare for a left turn.
-
8. Which helmet style gives the rider the most coverage?
Show answer
Answer C: A full face helmet
A full face helmet covers the chin and jaw as well as the skull, protecting the area that open styles leave exposed.
-
9. You are stopped at a steady red arrow pointing right, and no sign or state rule permits turning on a red arrow. May you turn right?
Show answer
Answer A: No, you must wait until the red arrow goes out and a green signal appears
A steady red arrow prohibits the movement it points to until a signal permitting it appears. Only a posted sign or a specific state rule allows a turn on a red arrow after a complete stop, so without one you must wait.
-
10. Which of these is a known cause of a high speed wobble?
Show answer
Answer C: Incorrect tire pressure or a load carried too far back and too high
Wobble is usually traced to tires, wheels, loading or poorly mounted accessories such as a windshield or fairing, so check pressures and how the machine is loaded.
-
11. Why should gloves and jacket sleeves overlap?
Show answer
Answer A: So no gap of bare skin is left at the wrist in a slide or the cold
The wrist is easy to leave exposed, and a gap there lets in cold air and takes the full force of a slide, so gauntlets or elastic cuffs should close the gap.
-
12. A yellow diamond in which one line joins another at an angle warns that
Show answer
Answer B: traffic from another roadway will merge into the driver's lane ahead
The merge sign warns that another traffic stream will join the same lane ahead, so drivers on both roadways must adjust speed and spacing.
-
13. What happens when tires are driven underinflated for a long time?
Show answer
Answer D: They wear at the edges, they run hot and they are more likely to fail
An underinflated tire flexes too much, which wears the shoulders and builds up heat that can destroy the tire.
-
14. Why do bridges and overpasses deserve extra caution when temperatures are near freezing?
Show answer
Answer A: They lose heat from above and below, so they ice over before the surrounding road
A bridge deck is exposed to cold air on both surfaces and has no ground beneath it to hold heat, so ice can form there while the connecting road is still only wet.
-
15. When should you arrange your way home if you plan to drink?
Show answer
Answer C: Before the first drink
Judgment is the first thing alcohol weakens, so the plan has to be made while you can still make a good one.
-
16. What is meant by keeping a space cushion?
Show answer
Answer C: Keeping open space on all sides of your vehicle so you always have somewhere to go
Open space ahead, behind and to the sides gives you time to react and an escape path when a hazard appears, which is the core idea of defensive driving.
-
17. Your passenger has ridden on other people's motorcycles before. What should you do before setting off?
Show answer
Answer A: Brief them anyway, because your machine and your instructions differ
Handholds, footrests, exhaust position and the signals a rider uses all vary from machine to machine, so every passenger is briefed on the machine they are about to ride on.
-
18. A driver stopped on suspicion of impaired driving refuses to take a chemical test. What happens?
Show answer
Answer D: A license penalty follows for the refusal itself
Under implied consent, holding a license means agreeing to testing, so a refusal brings its own suspension separately from anything the court decides.
-
19. A mixed drink is made with two shots of spirits. How much alcohol is that?
Show answer
Answer C: About two standard drinks
A standard drink is a fixed amount of pure alcohol, so a glass poured with two measures counts as two drinks however it is served.
-
20. A driver passes this sign on an open road. Over what stretch does the figure it sets stay in force?
Show answer
Answer A: From the sign onward, in every lane, until another sign sets a different figure
The figure governs the road from the sign onward and binds every lane, and it stays in force until a later sign sets a different one.
-
21. You are circulating in a roundabout and a vehicle is waiting to enter ahead of you. What should you do?
Show answer
Answer D: Keep going, because circulating traffic does not stop for entering vehicles
Stopping in the circle to be polite surprises the drivers behind you and defeats the design; entering traffic is the side that waits.
-
22. Besides motorist services and tourist information, a blue sign background is also used for
Show answer
Answer B: evacuation route signing
Blue is assigned to road user services, tourist information and evacuation routes, so hurricane and other evacuation routes are signed in blue.
-
23. The road is icy and visibility is poor, but you are driving at the posted speed limit. Is this acceptable?
Show answer
Answer A: No, because you may never drive faster than is safe for the conditions
Under the basic speed rule a driver must travel at a speed that is reasonable for the actual conditions, so a legal posted speed can still be an unlawful and unsafe speed.
-
24. What limits how much weight a motorcycle can carry?
Show answer
Answer A: The load limit given by the manufacturer for that machine
The manufacturer's figure covers the rider, the passenger and everything carried, and going over it overloads the tires, the brakes and the suspension.
-
25. You have just been involved in a crash on a city street. Which sequence of first steps is correct?
Show answer
Answer A: Stop where you are, check everyone for injuries, and then make the scene safe
You are required to stop, and the first priority at the scene is people, followed by preventing a second collision.
