Which factors affect your braking distance?
- Quality of your brakes, your speed, your foot size, your tire traction
- Your speed, the weight of your motorcycle, your tire traction, road conditions, quality of your brakes ✓
- Your speed, your brand of bike, your tire traction, road conditions, quality of your brakes
- All of the above
Answer: B. Your speed, the weight of your motorcycle, your tire traction, road conditions, quality of your brakes
Braking distance is affected by your speed, the weight of your motorcycle, your tire traction, road conditions, and the quality of your brakes.
Why this is the answer
The handbook breaks total stopping distance into perception, reaction, and braking distance, and then lists what braking distance itself depends on. It says speed matters most, and that the motorcycle's weight, how well the tires grip the road surface, and the condition of your brakes also change how far you travel before you stop. Adding road conditions fits the same idea, since the handbook treats the road surface as part of tire traction.
Why the other answers are wrong
- A. Quality of your brakes, your speed, your foot size, your tire traction — Your foot size plays no part in how far the motorcycle travels while braking, and that list leaves out weight and road conditions.
- C. Your speed, your brand of bike, your tire traction, road conditions, quality of your brakes — The brand of bike is not a factor the handbook names; what counts is weight, traction, road surface, speed, and brake quality.
- D. All of the above — Not everything listed is a real factor, so choosing every item would include things like foot size and brand that the handbook does not mention.
Remember it
Think of it as speed first, then the bike and the road underneath it: weight, grip, surface, brakes.
