The video was shared to popular social media site Reddit, where opinion was divided on the actions of the driver.
The man who posted the video told the Herald that the two drivers who went the wrong way down the motorway had "realised too late" that they were headed towards the traffic and "decided some creative driving was needed".
Another user sympathised with the drivers, writing that they had been stuck in a similar situation and understood people turning around to avoid long queues, "as long as they take the proper precautions".
Another user replied: "What are the proper precautions for reversing down a motorway? Honestly, you should have your licence removed."
Others suggested that the drivers' actions were "stupid and dangerous" and questioned why they couldn't accept their fate and wait "like everyone else".
Some said that the two drivers should have taken extra measures such as turning on their hazard lights and sticking to their edge of the lane as they headed back to the offramp.
Motorists were delayed for an hour by Saturday's crash, which was eventually cleared by 2.45pm.
Wellington Road Policing Manager Inspector Derek Orchard told the Herald that police were aware of the video and enquiries were underway to locate the driver of the vehicle that made the U-turn.
He said: "Manoeuvres such as this are not only illegal but they put the driver, their passengers and all other road users in danger."
