Ice smashes car windscreen

[Dum-Dum]

Amounts to criminal damage or some sort of offence, doesn't it? Driving without due care even?

You could argue that it is Criminal Damage as there is an element where you can be reckless as to whether your actions would cause the damage however it is much more likely that a ticket for insecure load would be issued, I have a feeling it's a standard non endorsable fine.

Yeah you can be fined in UK for not clearing your car of snow and ice. Not sure if enforced though.

It gets enforced as much as any other road traffic law, ie barely at all LOL
