Truck-thrown stones on the D'Aguilar Highway
The highway carries freight, livestock trucks and quarry haulage between Caboolture and Kilcoy, and a loaded tipper throws aggregate hard enough to star a windscreen in one hit.
Heavy-vehicle strikes are often deeper than they look from the driver's seat, and a deep chip spreads faster than a shallow one once summer heat works on the glass.
We check whether a chip has already cracked through the inner layer before recommending a repair. A clean chip clear of the edge and the camera can be resin-filled, often on your way into Caboolture.
