A 'speeding' drink driver crashed into a fuel station causing a huge fire in Thailand.

Truck driver Manoch Taengcharoen, 44, reportedly swerved into the fuel station claiming he had fallen asleep at the wheel after drinking.

The crash ignited the fuel pumps, with the fire rapidly engulfing the vicinity.

Police Major Ekkawit Thongpoom of the Mueang Lopburi Police Station said officers received a report at 1:30 am, and rushed to the scene with firefighters and rescue volunteers.

They found that Manoch's truck had slammed into the fuel dispenser, sparking the fire that also swallowed his vehicle. They said they worked quickly to keep it from spreading to the underground fuel storage around 20 metres from the station.

Attendants and workers from a nearby convenience store said they tried to put out the fire with extinguishers, but eventually fled as it grew larger.

The fire was extinguished in one hour and there were no casualties reported.

Police have detained Manoch, who allegedly showed signs of intoxication and whose breath smelled of alcohol.

He said he had been busy transporting concrete across different provinces, but did not know how he ended up on the road, which he said he rarely used. He also allegedly admitted to drinking alcohol before the crash.

Witnesses said Manoch was driving at a high speed before slamming into an electric post and swerving into the fuel station.

Manoch's blood alcohol reading was 171 milligrams per cent, and he was detained at the police station to face charges.

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.
