A stretch of the M6 at Penrith has reopened after cows closed the northbound carriageway.
At around 10am a Land Rover Discovery with a trailer full of cattle was involved in a crash with a Citroen Relay van, driven by a 32-year-old man from Birmingham.
Following the collision, in which neither driver was injured, cows got on to the carriageway.
A vet was called to the scene to check the animals and the motorway has now re-opened.
Animal health experts in southern Scotland say they are braced for the Schmallenberg disease to spread.
The virus was confirmed last week for the first time in mainland Scotland when it appeared on a farm close to Dumfries.
The disease, which can lead to birth defects in sheep and cattle, has already appeared in Cumbria.
Vets in Scotland say they will now monitor the illness closely.
