More details in the Channel 7 news
http://au.news.yahoo.com/ (look for video Cycling Tragedy, might only be on NSW site). My blood is starting to boil...
It turns out that the truck involved belonged to the same company (South Penrith Sand and Soil) that had a truck cause a fatality on the M7 a fortnight ago. That truck also veered inexplicably onto the shoulder, hitting a car that was parked there killing the driver who was taking a phone call. The truck driver in the M4 incident was a 27 year old. Cyclists injured in the crash are named in the Channel 7 report - it seems two have relatively minor injuries, and third (the girl) has more serious injuries (but not critical).
Both the driver and the trucking company are reported as being under investigation. I hope that throw the book at them, and the whole damned library.
Can anyone think of a reason the trucking company should not be ordered off the road, right now ???
edit:
South Penrith and Soil's depot is at
4 Harford Rd, South Penrith. Crash occurred just beyond the slip lane exiting to Northern Road. If you were westbound on the M4, and going to the depot by shortest route, you'd exit at the Northern Road. If you missed it, you could go along to the next exit at Mulgoa Rd and come back (adds less than 1km).
What chance this goat was asleep at the wheel, missed his exit and tried to swerve onto it at the last second, only to fail (e.g. traffic already in slip lane) and collect the cyclists on the shoulder.
