This is the shocking moment a 'drink driver' ploughed into students on a zebra crossing leaving four people injured in Thailand.

Jumroon, 65, rammed into motorycle riders and pupils at a pedestrian lane in front of the Chanthaburi Technical College in Chanthaburi province on May 16.

The alleged drink driver mowed down pedestrians and dragged along a motorbike for several feet as officers gave chase.

With the motorbike still caught on its bonnet, the car barreled forward without slowing down. It hit a schoolgirl, 19, walking home to her dormitory, and the young woman was left unconscious after banging her head on the pavement.

Jumroon finally came to a stop after crashing into another vehicle in front of houses.

He was arrested by police and found to be 'heavily intoxicated' with a blood alcohol reading of '285 milligram per cent'. The legal blood alcohol limit in Thailand is 0.05 per cent or 50 milligrams of alcohol in 100 millilitres of blood.

Four people were injured and brought to a hospital, with the 19-year-old student suffering a cerebral haemorrhage and requiring surgery.

Jumroon was later released on bail, local media reported.

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, cheap loans for cars, notoriously easy driving tests, police failures to enforce road laws as well as endemic corruption and chronic under-investment in infrastructure hamper the efforts.
