Motorcycle · Avoiding Hazards

A motorcycle is approaching a corner when the rider notices sand and gravel in the road ahead. The best immediate action is:

Correct answer

Slow down before reaching the gravel by reducing speed in a straight line; if you cannot avoid it, roll through it as upright as possible with minimal steering inputs and steady throttle — lean angle reduces tire footprint; avoid braking in gravel

  1. A Brake hard before reaching the sand
  2. B Slow down before reaching the gravel by reducing speed in a straight line; if you cannot avoid it, roll through it as upright as possible with minimal steering inputs and steady throttle — lean angle reduces tire footprint; avoid braking in gravel
  3. C Swerve to avoid it at the last second
  4. D Accelerate through the sand

Why this is the answer

Sand and gravel hazard management: Gravel on pavement is extremely dangerous — traction disappears and the bike can slide instantly.

Approach: Slow down as much as possible before entering the gravel section while the road is still clean (maximum braking in gravel causes falls).

If in the gravel: Reduce lean angle — more upright = larger tire footprint = more traction; avoid braking (both wheels in gravel = maximum sliding risk); steady throttle (small throttle changes); small, smooth steering inputs; look through to the clean road on the other side.

Surface hazards: Leaves, sand, gravel, paint markings, metal grating on bridges, steel plates, wet crosswalk markings, fresh asphalt — all reduce traction significantly; pre-ride: note road surface ahead; post-turn: check road surface before committing to lean angle; when in doubt about surface quality: slow down before leaning.
