A horror motorway pile-up left eight dead and three injured in Thailand.

Officials aid a family's SUV was sandwiched between two trucks, crushing the passengers inside in Samut Prakan on the outskirts of Bangkok, on Thursday evening.

Police and rescue teams arrived at Motorway 7 after being notified at 10 pm. They found the mangled wreckage of the family SUV, where a gruesome carnage of severed limbs and blood stained the inside of the vehicle.

Volunteers used cutting equipment to extract the bodies.

Authorities said eight, including two toddlers and a 10-year-old boy, were killed while three people, including truck driver Saneh Doktakien, 60, who allegedly caused the pile-up, were injured and rushed to the Chularat 9 Airport Hospital.

Police Colonel Kukkong Disawat, a Highway Police superintendent, said: 'Preliminary investigations revealed that there were ten passengers in the vehicle traveling from Bangkok to visit relatives in Rayong.

'Upon reaching the accident site, they pulled over behind a truck parked in the emergency lane so they could get diapers for a child in the car. However, another truck struck them from behind at high speed, resulting in multiple fatalities.

'Their other relatives have been informed and are on the way to the hospital. Investigators will question the truck driver and injured parties again and review CCTV footage to determine the exact cause of the accident.'

Another truck driver, Kwangkaew Chanpathum, 51, said he and his wife were delivering vegetable oil from Chumphon to Prachinburi when the accident occurred.

He said: 'We had parked in the emergency lane to have a quick meal, but after about five minutes, something rear-ended our truck and pushed us forward for several metres.'

Thailand has one of the world's worst road safety records. Ministers have set the goal of reducing fatalities from 32.7 deaths per 100,000 people to 12 per 100,000 people by the year 2027.

However, a lack of road safety education in schools along with notoriously easy driving tests, police failures to enforce road laws, and chronic under-investment in infrastructure, all appear to hamper the efforts.
