SUBJECT 4 · BAD WEATHER & ROADS

On which road surface are wheels most likely to lock up when braking?

A
Concrete road
B
Earth road
C
Ice and snow covered roads.
D
sand road
ANSWER · C
Ice and snow are very slippery, with the lowest friction. When friction between brake pads and discs exceeds friction between road and wheels, the wheels lock and slip. So wheels are most likely to lock when braking on ice and snow.
