On Wednesday drivers in Devon and Cornwall reported being stuck for hours after snow caused some roads to close.

One motorist, Michael, told BBC Radio Devon: “We drove for just under an hour when the traffic came to a standstill in very heavy snow.

“We took the decision to turn around… and I think we’ve moved 100 yards in three-and-a-half hours.”

Gritters working into Thursday morning have been fitted with ploughs to clear routes in the area, according to authorities there.

Car insurer RAC said it has seen the highest levels of demand for rescues in a three-day period since December 2022.

“Cold conditions will last until at least the weekend, so we urge drivers to remain vigilant of the risks posed by ice and, in some locations, snow,” said RAC breakdown spokeswoman Alice Simpson.

National Rail have also advised passengers to check before they travel, as ice and snow can mean speed restrictions and line closures.

On Wednesday evening, poor weather was affecting Northern and Great Western Railway.

Buses are also replacing trains between Llandudno Junction and Blaenau Ffestiniog until Monday.
