Two Chinese tourists were killed and two others were injured in a horror crash with a 22-wheeler truck in Thailand.

The SUV with the four Chinese men allegedly cut in front of a cement truck while emerging from a motorway tunnel in Pattaya, on February 19 morning.

The truck rammed the SUV, sending it spinning out of control. A parked black sedan was also damaged in the crash.

Rescue volunteers arrived at the scene after receiving a report. They found the crumpled white Ford with the Chinese passengers trapped inside the crushed wreckage.

Footage shows rescue officers prising the car door open with tools as medics administered first aid to the bleeding Chinese tourists. However, two of them who suffered critical injuries could not be revived.

Authorities said two other seriously injured passengers were rushed to a hospital.

A police spokesman from the Bang Lamung district station said: 'We have inspected the scene and recorded evidence.

‘We believe the Ford car suddenly pulled ahead of the truck, causing the severe accident that resulted in deaths, injuries, and property damage.

‘We will conduct an investigation to determine the exact cause of the accident before proceeding with legal action.'

Truck driver Sombat Penmak, 56, said he was delivering cement to Rayong province when the Ford suddenly barged into his lane.

He said: 'The car suddenly appeared in front of me without warning. I could not avoid it because I had no time to react.'

The fatal accident is the latest involving tourist deaths in Pattaya.

On February 16, German father Mario Dieter Prade, 44, was killed when he crashed headlong into an oncoming Toyota Fortuner.

Police arrived at the scene and found the husband's mangled body splayed out among debris.

On February 6, an American motorbike rider was also killed in a gruesome crash, also in Pattaya City.

Leo Williams, 52, from Florida, was on a high-speed joyride when he lost control of his motorbike in the early hours of the morning. He was turning a curve but shot right into the tree-lined median strip in the Soi Thap Phraya 9 area.

The motorbike ripped through trees before toppling over in the middle of an intersection. Police later found Leo with his chest torn open.

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.
