A bus operator in the Scottish Borders has suspended all its services due to diesel freezing in its vehicles.
Munro's buses operate on routes between its base in Jedburgh and Kelso, Galashiels and Edinburgh.
Temperatures in the Borders fell to -15C (5F) overnight and are still well below zero in many parts of the region.
The area's other main operator, First Bus, was reported to be running a near-normal timetable.
Gavin Whittaker, from the village of Heriot in the Borders, contacted the BBC news website to describe the difficulties being encountered there.
He said it was -20C with a lot of disruption on the roads.
"The A7 is really dangerous," he said.
"Gritters are going along the roads but not spreading salt because it's simply too cold to do so.
"Cars just won't start here, especially vehicles using diesel, the diesel is freezing or turning to wax and the cars won't start."
