A Dales road is blocked after a gritter overturned.
The accident happened this morning between Marske and Low Fremington, near Reeth.
Police say they were called at 7.20am.
A spokeswoman for North Yorkshire Police said nobody was injured in the crash.
Firefighters have been called to the scene.
The road remained blocked at 10.30am although a recovery vehicle was on its way, police said.
North Yorkshire County Council’s head of highway operations, Nigel Smith, said: “We are aware that one of our gritters was involved in an incident this morning while out treating our Priority 2 network in Richmondshire.
“Fortunately the driver is OK and we arranged for immediate support to deal with this and to ensure the network treatment was completed.
“This shows how challenging conditions can be.
“People should drive with caution on the highway network, with additional care required on untreated surfaces.
“Furthermore, we would advise people to plan and prepare for their journeys and, if those journeys are necessary, allow additional travel time during winter conditions.’’
North Yorkshire County Council said its highways gritting teams had been working around the clock to keep the county’s roads open as the current cold snap bites.
With road surface temperatures below zero, snow showers have been creating hazardous conditions and gritters and farming contractors have kept all major routes open, officials say.
