This is the frightening moment a lorry overturned after speeding past a line of traffic.
The dash cam video was caught in Russia and shows a line of traffic on a two-way stretch of road.
Suddenly, a truck can be seen undertaking the row of stationary cars at high speed. As it does so the trailer hits the grass verge, causing the entire lorry to lose control.
Soon the trailer smashes through the barrier and down into the forest next to the road, taking the rest of the cab with it. The barrier is flattened as it topples down into the ditch.
The truck eventually comes to rest upside down while other motorists stop quickly and scramble out to go and help the driver.
It is reported that although shaken, the driver of the truck was not seriously injured.
