High Quality Content by WIKIPEDIA articles! Side collisions are vehicle crashes where the side of one or more vehicles is impacted. These crashes often occur at intersections, in parking lots, when two vehicles pass on a multi-lane roadway, or when a vehicle hits a fixed object. Broadside collisions, commonly known as T-bone collisions, are where the side of one vehicle is impacted by the front or rear of another vehicle or a fixed object. Vehicle damage and occupant injury are more likely to be severe, but severity varies based on the part of the vehicle that is struck, safety features present, the speeds of both vehicles, and vehicle weight and construction.
