Sample Practice Questions
Try these 10 sample questions from the Riding Theory Test practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.
1How does increasing riding speed affect the rider's field of vision?
- A.It becomes wider.
- B.It becomes narrower.Correct answer: B
- C.It changes only with mirror adjustment.
- D.It remains unchanged.
Explanation: The handbook states: "As the vehicle speed increases, your field of vision would be reduced." Increasing speed reduces the rider's field of vision. Widening, no change and a dependence only on mirror settings do not describe this effect.
Reference: Riding Theory Booklet — Official Handbook — p. 6, paragraph 13
2In a four-stroke engine, which stroke draws the fuel-air mixture into the cylinder?
- A.Compression stroke
- B.Induction strokeCorrect answer: B
- C.Exhaust stroke
- D.Power stroke
Explanation: The handbook states: "With the inlet valve opened, petrol and air mixture are drawn into the cylinder. This downward movement is known as the Induction Stroke." Induction admits mixture. Compression squeezes it, power follows ignition, and exhaust expels burnt gases.
Reference: Riding Theory Booklet — Official Handbook — p. 11, paragraph 34
3When should a rider adjust the mirrors for normal pre-ride use?
- A.With the motorcycle off its main standCorrect answer: A
- B.With the motorcycle on its main stand
- C.Only after joining moving road traffic
- D.Only while the engine is accelerating
Explanation: The handbook states: "Do not adjust the mirror while the motorcycle is on the main stand." Set the mirrors in the riding condition rather than on the main stand. Adjusting while moving or accelerating is not a substitute for pre-ride preparation.
Reference: Riding Theory Booklet — Official Handbook — p. 26, paragraph 73
4On the manual motorcycle described in the handbook, which throttle movement increases engine speed?
- A.Twist the grip away from you.
- B.Twist the grip towards you.Correct answer: B
- C.Press the grip towards the wheel.
- D.Release the grip to its idle position.
Explanation: The handbook states: "To increase engine speed twist it towards you. To decrease engine speed twist it away from you." Twisting towards the rider increases engine speed. Away decreases it; release returns it to idle, and pressing is not the described rotary operation.
Reference: Riding Theory Booklet — Official Handbook — p. 27, paragraph 76
5When preparing to start the manual motorcycle, what should the rider confirm with the neutral indicator?
- A.That top gear has been engaged
- B.That no gear has been engagedCorrect answer: B
- C.That the clutch lever is released
- D.That the side stand is extended
Explanation: The handbook states: "Check that the gear is not engaged by visually observing the green lighting of the neutral lamp displayed as Neutral “N”." The N lamp confirms neutral, not clutch position, top gear or side-stand position.
Reference: Riding Theory Booklet — Official Handbook — p. 39, paragraph 108
6While climbing a slope, the motorcycle loses speed and struggles in the selected gear. What should the rider do?
- A.Select a lower gear and accelerate appropriately.Correct answer: A
- B.Select a higher gear and reduce engine speed.
- C.Select neutral and coast towards the summit.
- D.Keep the same gear until the engine stalls.
Explanation: The handbook states: "Should the vehicle show signs of losing speed, quickly change to a lower gear and accelerate." A lower gear restores suitable climbing drive. Higher gearing, neutral or waiting for a stall does not address the loss of speed.
Reference: Riding Theory Booklet — Official Handbook — p. 61, paragraph 172
7What is the main aim of defensive riding?
- A.To make other drivers yield through assertive riding
- B.To replace observation with confidence in traffic signs
- C.To stay in control by anticipating other users' actionsCorrect answer: C
- D.To maintain the same speed despite changing hazards
Explanation: The handbook states: "Defensive riding is a set of strategies that helps motorcycle riders to always be in control and not to be caught unaware by the improper actions of other road users." Defensive riding anticipates hazards and preserves control. It does not force others to yield, replace observation or require fixed speed.
Reference: Riding Theory Booklet — Official Handbook — p. 68, paragraph 196
8Which licence class covers a petrol motorcycle with an engine capacity of 300 cc?
- A.Class 2B
- B.Class 2ACorrect answer: B
- C.Class 2
- D.Class 3
Explanation: The handbook states: "Between 200cc and 400cc." 300 cc falls inside the stated Class 2A band. Class 2B is the smaller motorcycle category, Class 2 the larger, and Class 3 is not this motorcycle class.
Reference: Riding Theory Booklet — Official Handbook — p. 3, paragraph 3, Class 2A / Petrol motorcycles
9A rider is taking medicine that may cause drowsiness. What should the rider do before deciding to ride?
- A.Assume a prescribed medicine cannot impair riding.
- B.Rely on a shorter trip to prevent any impairment.
- C.Ask the doctor whether it affects riding ability.Correct answer: C
- D.Use extra coffee in place of checking the effects.
Explanation: The handbook states: "If you are on medication, check with your doctor whether the prescribed medicine you are taking will affect your riding ability." Medicinal use does not establish fitness to ride. Check with the doctor; a shorter trip or coffee does not establish that the medicine is safe for riding.
Reference: Riding Theory Booklet — Official Handbook — p. 6, paragraph 14
10Why are disc brakes less prone to brake fade than drum brakes, according to the handbook?
- A.They avoid friction during braking.
- B.They need no brake-pad replacement.
- C.They operate without producing heat.
- D.They dissipate braking heat faster.Correct answer: D
Explanation: The handbook states: "Compared to drum brakes, the disc brakes dissipate heat more quickly thus making disc brakes less prone to fading." Faster heat loss reduces fading. Disc brakes still use friction, create heat and have wearing pads.
