Multiple-vehicle collisionAustralia
243. Multiple-vehicle collision
A multiple-vehicle collision is a traffic accident involving three or more vehicles. It can occur when one collision triggers additional impacts, especially in heavy traffic, poor visibility or slippery conditions. These crashes can be difficult to assess because several vehicles may be damaged and responsibility may involve more than one driver. After a multiple-vehicle collision, drivers should make the scene safe, assist injured people, contact emergency services when necessary and carefully document the vehicles, damage and circumstances.
