WATCH: Driver screams as truck crashes into him while attempting merge
A driver was left fearing for their life after a truck merged into his lane, almost crushing his car, on a Sydney road.
The man was driving along Roberts Road in Greenacre, in Sydney’s south-west, when a truck came up behind him.
Dash cam video shows the truck accelerating behind the car in the next lane.
The truck begins to pass the driver. It's unclear whether the car speeds up or the truck slows down but the front of the truck ends up in line with the boot of the car.
In the next second, the truck begins to merge, leaving the driver of the car terrified. The vehicles connect and the car begins to spin out of control.
"F***," a person in the car can be heard saying before screaming: "Oh, f***ing idiot! He hit me".

When the video was posted to the Dash Cam Owners Australia Facebook page, many were left divided as to who was at fault.
"He cannot slow down and merge safely behind you because without trucks Australia stops," one man wrote.
"After 35 years of long haul and many millions of km's I fail to see how it's the cars fault," another person wrote.
"Sometimes people can't move out of a blind spot because someone is in front of them and in this case the truck put the car in the blind spot in the first place."
Another person pointed out that the truck approaches the car from metres back before attempting to merge.
"The truck approached him from behind from at least a car length back - if he can’t see out his windscreen at a car in front of him, or remember for 30 seconds he’s passing a car, he shouldn’t be driving a truck," the person wrote.
Another person said while they believe it is the truck driver's fault, the car driver should have been aware of what was happening.
"Truckie must have the memory of a gold fish, this was the truck drivers fault," the person wrote.
"But as for the cam car driver, you should be aware of what’s around you and behind you 360 degrees using your mirrors.
"Too many drivers just zone out at what’s in front of them. Spacial awareness and drive defensively people. Never assume."
