Two Rio Tinto workers were lucky to escape injury after their vehicle became pinned under a haul truck at one of the company's Pilbara iron ore mines.
The incident occurred on Saturday at the Brockman 4 iron ore mine site, about 60km north-west of Tom Price, when a haul truck collided front-on with a 4WD that became crushed under the truck's front wheel.
It is understood that the truck driver was unaware of the collision and had dragged the 4WD for 40m before pulling to a stop after receiving radio calls from the vehicle's two occupants to stop.
A spokeswoman for Rio Tinto said the workers got out of the vehicle safely.
An investigation is under way.
