New dash cam footage has shown the moment a game of 'chicken' went disastrously wrong.
A boy is knocked over by a 40-tonne truck travelling at 45 miles per hour after playing the game of dare with another young pal.
While his friend escaped unscathed, the 14-year-old youngster is knocked to the ground by the HGV and rolls over several times due to the impact of the collision.
Then, amazingly, he gets up and jogs to the side of the road - escaping with just a badly bruised ankle.
The collision took place on a country road on the A449 at Dunston in Staffordshire.
The SmartWitness SVC-1080 vehicle journey recorder showed that the truck was travelling at 45mph at the point of collision.
85% of pedestrians are killed in road collisions occurring at 40mph, according to the Royal Society for the Prevention of Accidents.
The death rate falls to 45% for collisions happening at 30mph and to just 5% when they occur at 20mph.
The truck driver immediately alerted police after the collision. He was 'badly shaken' afterwards but relieved that the boy was not more seriously hurt.
Officers chose to take no further action once they had viewed the footage and realised that the boy had caused the collision by playing chicken and the driver was blameless.
Mark Berry, SmartWitness's International Sales Director, said: "Obviously it was a huge relief to everyone that this lad was not more badly hurt.
"His escape is frankly remarkable given the size of the truck and the speed it was travelling at the time of the collision. He only had a badly bruised ankle.
"The driver was clearly badly shaken by the incident and immediately presented the footage to police.
"Once they had viewed the footage, it was clear that the driver was blameless and this was a game of chicken which had gone disastrously wrong.
"We have released the footage this week during half-term to show the crazy risk a very small number of youths are taking by playing chicken. I don't think anyone viewing the footage would ever contemplate playing chicken again."
Berry added: "In this case, the driver was able to go straight to the police and show clearly what happened. The footage showed the boy had badly mistimed running out into the road while playing chicken and was hit by the truck when it was braking heavily while travelling well within the speed limit.
"It happened on a rural road with no witnesses. Let's imagine what might have happened if it had not been captured on the camera.
"The driver could have been blamed for causing the accident and it would have been his word against that of the two youths. There would have been no way of proving his innocence."

The driver was declared blameless although he was quite clearly exceeding the speed limit for a single carriageway road - 87km/h equates to 54mph. 14mph over the speed limit for the type of vehicle.
