This is the moment a car filming escapes at the last minute from a runaway lorry that caused chaos in a resort town when its brakes failed, slamming into eight cars before being stopped by a dump truck.

The terrifying pile-up happened in the city of Sochi, Russia's most popular summer resort spot, at about 2:15pm on Wednesday, 14th May.

According to traffic inspectors, the KAMAZ lorry suddenly lost its braking system while travelling at an estimated speed of between 37 and 50 mph.

Dashcam footage shows the lorry smashing into stationary vehicles and eventually coming to a halt only after hitting the rear end of a second heavy-duty dump truck.

Witnesses say the second truck had deliberately blocked its path in an apparent effort to minimise the carnage.

Local officials confirmed that the incident led to a multi-mile traffic jam in one of the busiest parts of the city.

The Russian State Traffic Safety Inspectorate reported that four people sustained bruises but there were no fatalities.

Emergency responders and medical staff arrived at the scene within 10 minutes of the crash.

A detour was quickly organised through nearby villages while a fuel leak from the lorry was brought under control by fire services.

A technical inspection of the KAMAZ was carried out on site before it was removed from the area.
