A driver narrowly avoided disaster after a caravan roof blew off, slamming into the road only metres away from his vehicle on a Sydney highway.
The near-miss was caught on the driver's dash-cam, with the footage being uploaded to Facebook yesterday.
The video shows the roof of a white caravan suddenly rip off and fly into the air before smashing into the Hume Highway at Campbelltown, only just avoiding vehicles in the surrounding lanes.
"Lucky I moved left when I did. The cars behind me weren’t so lucky," the dashcam footage owner, Paul, wrote on the Facebook post.
No one was injured in the incident according to 9 NEWS.
