Snow and ice hit parts of Cornwall overnight
Snow and freezing temperatures have hit parts of Cornwall overnight.
The Highways Agency said that gritters had been to the A38 and A30 overnight and teams were continuing to patrol and grit main roads.
Cornwall Council said its winter maintenance plans had been put into place, but that no response protocols had been triggered.
Snow started falling just after 0500 GMT in parts of Cornwall including Penwithick, Bugle and Roche.
Two Roselyon Coaches became stranded on Penpillick Hill between St Austell and Lostwithiel during the morning rush hour.
Both buses were empty but were bound for a local college and school.
The coach company also said it was not running coaches between St Austell and Lostwithiel and some areas of St Dennis because of the difficult driving conditions.
Some cars have also had to pull over and are waiting in a lay-by for conditions to improve.
Alison Sixsmith from the Highways Agency said: "It's been a very busy night - all of our gritters have been out overnight, all of the routes have been gritted once, many have been done three times.
"All the gritters are out patrolling and just gritting where they need to at the moment.
"It looks like this is set to continue for the next few days and possibly get worse; that's something we'll review as we get the next up-to-date forecast."
Head of emergency management at the council Richard Fedorowicz said: "The planned winter maintenance will be put into place.
"Certainly the conditions haven't triggered anyone of our response protocols."
Mr Fedorowicz said that teams at the council were putting together plans after learning from the severe weather conditions in January.
He also said that the council had set up a dedicated snow webpage with information for residents on it.
The Priory Day Centre and Blantyre Centre both in Bodmin for adults with learning disabilities have had to reduce their services and Robartes Junior School has been closed for the day.
The school said: "Originally we were going to open for 1030 [GMT] but as roads around Bodmin are gridlocked and we only have a skeleton staff, we will be advising parents to keep children at home."
