The M4 was brought to a standstill after a lone black cow decided to block the road.
Police cars descended on the motorway in Cardiff between junction 32 and junction 33 westbound heading to Capel Llanilltern on Saturday.
Footage of the obstruction shows a motorist approach the scene in disbelief noting the ‘major disruption here on the M4’.
The content creator, Jake Abanos, adds: ‘It’s because there’s a cow. And the police don’t know what to do with it.’
A cluster of four police cars can be seen confronting the animal but it stubbornly stands its ground.
It comes as the queue of drivers also visibly slows down on their approach to the scene.
But at last the cow left with Traffic Wales South reporting on their X page the road had been cleared by 3pm.
It is not the first time the M4 has been blocked in unusual circumstances.
In February this year, traffic was tragically brought to a halt after ‘human remains’ were found on the carriageway between Junctions 20 and 21 in Gloucestershire.
A spokesman for Avon & Somerset Police said at the time: ‘Police were called at 6.40pm on Saturday 22 February by several drivers reporting something in the road.
‘Officers attended and found human remains.’
National Highways warned drivers stuck within the closures to ‘not attempt to turn around until instructed to do so’.
‘Road users caught within the closure will be released by turning around under supervision of our Traffic Officers and police. This is a complex operation and will take time due to the location and volume of traffic,’ they said.
