CCTV footage shows how the HGV made a right turn at a junction.
But the driver was apparently unable to steer the bulky lorry into the correct lane.

Instead, he steered it into traffic waiting at a red light.
A couple of bikers could be seen riding out of the way in the nick of time.
The lorry then hit a car head-on, shunting it backwards into the bonnet of a second car.
The cars were then pushed into several stopped motorcyclists, toppling them like bowling pins, as reported by Need To Know.
Other vehicles were also displaced as the lorry continued down the wrong lane, causing a chaotic pile-up.
Felled bikers could be seen picking themselves up and running out of the way.
The chaos unfolded yesterday (19 Mar) morning in Manaus, Brazil.
Some reports say the trucker lost control of the lorry while making the turn. Other reports say the vehicle’s brakes may have failed.
One motorcycle ended up underneath a car during the pile-up.
Luckily, the affected drivers and riders escaped with minor cuts and scrapes.
Their vehicles ended up worse for wear, however, with at least five cars and two motorcycles affected.
The cars were dented and one bike ended up completely wrecked.
After the incident, officials were called in to restore order to the traffic flow.
