Video: Reckless Teenager Hitches Ride On Back Of Lorry

A shocking video has emerged of a teenage boy riding on the tailbar of a 40 tonne lorry.

The reckless youngster can be seen coolly sitting on the rear of the vehicle in his school uniform in an act that police say could have killed him.

The teenager leapt on to the back of the TNT delivery lorry as it made its way through Blackburn, Lancashire. After seemingly enjoying the 30mph ride for around half a mile – which included an up hill slog and a major road junction – the boy jumped off and gave the thumbs up sign to passengers in the car behind him. The driver was unaware he had an extra passenger.

The footage, presumably filmed on a mobile phone, was uploaded to Facebook.

The police say they are trying to find the boy and speak to him about his 'extremely dangerous and reckless' prank.

Kevin Clinton, head of road safety at the Royal Society for the Prevention of Accidents as said it was a 'dangerous and foolish act which could easily result in serious injury or death' and that they 'urge teenagers not to give into peer pressure or to encourage others to copy this behaviour'.

A spokesman for TNT Express said they were aware of video footage. "TNT does not condone such dangerous and illegal behaviour which could lead to serious injury or worse," their representative said. "We take such matters very seriously and are doing everything possible to help police with their investigations."Video
