Students at Uxbridge College were given a graphic glimpse of a road crash as part of National Road Safety Week to demonstrate the consequences of speeding.
The reconstruction took place in the College car park and displayed a collision between a car and a motorcyclist - Public Services students played the parts of the victims.
The audience got the chance to see the car occupants cut free by the London Fire Brigade, and receive emergency medical treatment.
Laraine Smith, Principal of Uxbridge College, said: "Helping students stay safe and well is an important part of Uxbridge College's work to support them in as many ways as possible, and this reconstruction got a serious message across in an unforgettable way. We have had a huge amount of interest in the Road Safety Week events, which shows young people are taking their safety and other people's very seriously indeed, and this can only be good news."
Councillor Keith Burrows, Cabinet member for Planning and Transportation at Hillingdon Council, said: "These dramatic scenes are hard hitting and a stark message to all road users. We hope that events like this will highlight the sad consequences of bad driving and will contribute to reducing collisions on our roads to make them safer for all."
The re-enactments were set up by the London Safety Camera Partnership, Hillingdon Council's Road Safety Unit, Metropolitan Police, London Ambulance Service and the London Fire Brigade to help reduce the number of collisions taking place on Hillingdon's roads.
