On a busy freeway in Sydney, the black sedan merged into the path of an oncoming truck traveling at 90km per hour and collided with the vehicle. The driver of the sedan stupidly slammed the brakes right after the first collision, causing a second one and then failed to lift her handbrake when attempting to exit her vehicle causing her car to roll back and hit the truck again.In Australia, when you are involved in an accident and your car can still move, you must safely move your vehicle off the road so that you are not a hazard to other oncoming vehicles.When the truck driver asked the female driver to move her vehicle off the road, she refused and was insistent on getting the truck drivers details. Only after when the truck driver lost his patience and yelled at her did she get back into her car and drive it to the side of the road.
