They don’t. You haven’t lived until you’ve been in a tank skidding sideways on ice. It stops when it wants to, and as you can imagine, 68 tons (an American M1) can build some momentum...
I think there are some vets on this list who will concur with your memory.

I saw a really funny video clip a few months ago where Finnish (pretty sure) tank crews were power-sliding their Leo 2A5’s around a frozen track at their motor pool.
Those wacky kids!
