While it may be impossible to know why the driver of this Holden Commodore lost control they way they did, what we can say is that the motorist wasn’t exactly driving properly before the accident.

Video captured via dashcam prior to the crash itself shows the Commodore moving a bit oddly within its lane, straddling the right side marking briefly before suddenly veering off the road.

Whatever happened, it was apparently serious enough that the driver was unable to maintain control of the car. After hitting the guardrail (as well as probably the base of that highway sign), the car bounced back towards traffic while rolling over once. Thankfully, it landed on its wheels.

Here’s how it went down in the words of the person driving the dash-cam vehicle:

“Single car accident yesterday afternoon, southbound on the Pacific Highway at Sapphire Beach near Coffs Harbour. The driver was driving erratically in the lead up to the accident and somehow veered off to the left, hitting one of the massive signs. This caused the car to roll, blocking both lanes of the highway and causing traffic to come to an immediate stop. Apart from the accident, the main concern was the fuel tanker that was behind us but luckily he was able to stop in time.”

While we applaud him for rushing over to help, in this type of situation it’s better to wait a few moments just to make sure traffic behind you really has come to a stop.
