Bizarrely, a moped is left trundling on the far right of the track, which is understood to be the tunnel Avenue Avenida Colombia in Cali, Colombia.
Cars build up on the right side of the road, allowing the filming driver to pull clear on the left behind the leading cars.
He slows down as he approaches a gradual left turn, but the Mercedes accelerates into the bend and over-takes on the right.
The driver loses control and smashes into the right wall of the tunnel, which causes the A-Class to flip onto its side.
It leaves a trail of sparks as it slides along the road, still on its side, before coming to an abrupt stop when it smashes into a barrier at a junction shortly after exiting the tunnel.
It appears the car crashed into the barrier roof-first.
The bonnet is completely destroyed, windows are smashed and the wheels are facing the wrong way.
The driver and his passenger were saved by the car's airbags, and miraculously only suffered minor injuries, according to Koreus.
