A scraper truck includes a main scraper mounted to a wheeled vehicle and side scrapers pivoted to the main scraper at its ends. The side scrapers are pivotally movable between extended lateral positions where the side scrapers extend outboard of the opposite ends for collecting debris located outboard of the vehicle's width, and a retracted position where the side scrapers are in overlapped juxtaposed storage positions close to and in front of the main scraper. The main scraper has a front face that is concavely shaped. The scraper mount defines a vertical pivot axis and the scraper assembly is rotatable about the vertical pivot axis upon striking an object toward an end of the scraper. A biasing mechanism is provided for biasing the scraper toward a centered forwardly-facing position, and a shear pin is configured to break prior to damage to the scraper or vehicle frame.
