A family was going for a weekend away when a concrete power pole fell on their car.

Natchawan Sangmuan, 41, was in the front passenger seat with husband Sittikorn Gnamwan, 40, and son Parattakorn, 8, in the back as they drove alongside a new highway being built in Nakhon Ratchasima, Thailand, on May 25.

But mid-way through the journey, a cement mixer appears to pull over a concrete post holding power cables which plunges into the windscreen of their white Toyota saloon.

Horrifying dash cam footage (showing the wrong date and time) captures Natchawan screaming in the accident, which has left her in a neck brace ever since.

The mother-of-one said her son had ''blood pouring down his legs'' after being cut by shards of flying glass and her husband was also injured.

The family are furious that the construction firm in charge of the road has only offered them 50,000 baht (1,140gbp) in compensation - which they turned down - claiming it is not even enough to cover the cost of damage to the car.

Natchawan said: ''We were going on a weekend away as a family and it turned into a nightmare.

''As we drove along the motorway a cement truck on the construction site knocked over a concrete pole and it fell onto our car.

''There was nothing we could do.

''My husband did his best to get the car out of danger so it did not cause a bigger accident.

''I came from the car and had a sharp pain in my neck and chin and I have been wearing a neck cast since the accident.''
