What does a traction control system (TCS) help to prevent?
- A Wheelspin when accelerating
- B Skidding when braking too hard
- C Uneven front tyre wear
- D Uneven rear tyre wear
Why this is the answer
TCS helps to prevent the rear wheel from spinning, for example when accelerating on a slippery surface.
Why the other answers don't fit
- B
- Skidding when braking too hard — Skidding under braking is what ABS deals with. Traction control works on the other side of it.
- C
- Uneven front tyre wear — Front tyre wear comes from the road and your riding, and the front wheel is not driven at all.
- D
- Uneven rear tyre wear — Even wear is a side effect at best. The system exists to stop the driven wheel spinning up.
