CDifficulty 3/5

Which statement about braking distance on an icy road compared with a dry road at the same speed is correct?

Correct answer

It can reach ten times the dry-road distance; this is not a guaranteed limit.

It can increase greatly; educational guidance cites that it can reach ten times the dry-road distance. This is neither a guarantee nor a universal physical maximum: ice condition, tyres and other circumstances matter. A tenfold distance means a total ten times the reference, rather than adding ten times more. Reduce speed substantially and increase separation; do not assume ABS restores dry-road grip.
