Surface and acceleration

Why are roads covered with leaves, gravel, or snow particularly dangerous for strong acceleration on an A2 motorcycle?

Because the motorcycle gets better grip on uneven surfaces and accelerates easier.
Because leaves, gravel, and snow significantly reduce friction between the tire and the road, making the wheels spin easily and the motorcycle skid.
Because the motorcycle brakes faster on such surfaces.

Explanation

✅ The driver's license book warns that surfaces with leaves, gravel, or snow have low friction; during strong acceleration, the wheels risk spinning, which reduces control and increases accident risk.
