The truck, which was transporting 13,000 litres of heating oil, smashed against the guard rail along the road.
Following impact, the steel barriers were unable to support the lorry's weight, bending and buckling, leading the vehicle to teeter in an unstable position.
Emergency services arrived at the scene towards the end of the morning to stabilise the vehicle and ensure it doesn't fall into the ditch. The priority is to prevent the heating oil from spilling out and polluting the area.
A water reserve is located not far from the accident site.
The road remains closed with emergency services deal with the incident.
