It's a salt/sand mix, since the sand (grit) provides extra grip.

If it's really cold (I assume this can happen in Scotland) it would just be grit.

(I'm not sure why "gritter" would be difficult to work out. "Grit" is a normal English word: bits of grit in the cabbage, 100 grit sandpaper.)

UK rock salt grit comes from here: https://www.saltassociation.co.uk/education/make-salt/rock-s...

The UK's biggest rock salt mine is in Winsford in Cheshire https://en.wikipedia.org/wiki/Salt_in_Cheshire https://en.wikipedia.org/wiki/Winsford#Rock_salt

Additionally part of the mine is now used as a deep secure store for files from the health service.

Mainly rock salt but doesnt work in extreme cold as the ice freezes with the rock salt in it. Ruins the vehicle chassis in the European country's which salt their roads but it keeps the Car industry going, not to mention pollutes water courses and crops.

And my favorite: in northern Scandinavia we try to be careful with salt because reindeer find it tasty...
