I always believed the wire rope barrier were not to catapult vehicles back onto there own lane, but the exact opposite. Concrete and Armco rails tend to do just that. The wire rope was designed to slow the vehicle to prevent vehicles crossing to the incorrect side of the road, or leaving the road way and NOT to flick them back.
After the recent bushfires on the North coast, many kilometres of wire rope barrier had to be replaced as the fire had melted the plastic spacers and post anchor sleeves, causing the wire to lose tension. A big expense not found with either concrete or steel rails.
where are the marks and damage on the road surface? You would think if the wheels came off while it was moving, and we are looking at the back of the tanker, that there would be a scars in the road where is might have dragged for a bit. It looks like someone carefully lifted the tanker, removed the wheels and gently sat it down on the road.
Gyphon, I think we are looking at the front of the tanker. Photo is taken in the US and the tanker is probably the second trailer in a small double combination (trailers are only about 25 feet long) and the dolly has come free letting the front of the trailer nose dive into the tarmac/asphalt/bitumen
