One of Scotland’s largest councils has warned it could stop gritting some roads because of attacks on gritting lorries and their drivers.
North Lanarkshire Council has already stopped regularly gritting in one area because of safety concerns.
The local authority has said it will do the same in other places if it has to.
In the worst incident, the windscreen of a gritter was smashed when a man punched through it. The driver narrowly avoided injury.
The council said attacks on gritters had become a serious concern and it has now declared a zero tolerance policy.
It is believed to be the first local authority in Scotland to publicly admit areas have not been gritted because of concerns for the safety of staff.
The council said roads in the Pather area of Wishaw had not been treated regularly for two years.
In Cumbernauld mini-tractor drivers were pulled off snow-clearing duties after coming under attack.
