The moors road between Whitby and Guisborough has been dramatically closed this afternoon (Monday) as smoke and flames billowed across the paths of cars leaving drivers unable to see.
Reports of problems started coming in at around 1pm when what is believed to have been controlled heather burning became affected by strong winds.
Cars travelling along the A171 near the turn off for Ugthorpe were plunged head first into the smog with unconfirmed reports that two vehicles collided after one ended up on the wrong side of the road. However, no-one is thought to have been injured.
Fire crews are at the scene and the road is closed from Sleights road end roundabout and the Ugthorpe turn-off.
