This is the dramatic moment a drunk driver crashed into a motorcycle, injuring a family of three in Thailand.

CCTV footage shows the orange pickup truck rear-ending a two-wheeler near an intersection in Bangkok on June 20.

Instead of stopping, the inebriated driver, Pitak, 49, allegedly fled the scene with the motorcycle still lodged under his car.

Motorists chased the hit-and-run suspect as he sped away, leaving a spectacular fiery trail on the tarmac. He was later cornered and mobbed by furious drivers before police arrived to arrest him.

Authorities said a father Akkhadet, 44, his wife Kanokrat, 31, and their son Ratchanon, aged five, were found lying on the road and crying for help. They were rushed to a hospital for treatment.

A Bang Bon Police Station spokesman said: 'The driver was found acting drunk and smelling strongly of alcohol. He underwent a blood alcohol test for the police record.'

Pitak was reportedly granted bail that night, but returned to the police station the next day to apologise.

He was said to have bowed in front of the police, claiming he did not see the motorcycle in front of him.

He allegedly said: 'I admit that I had been drinking, but it was not my intention to escape.'

Police said Pitak will be charged with driving under the influence, reckless driving causing serious injury, and fleeing without reporting to the authorities.

He was detained in police custody to face legal action.

Despite being one of the wealthiest countries in Asia, Thailand suffers from chronic underinvestment in its highways and education, contributing to its poor road safety levels. Only a handful of African countries are worse.

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.
