Vehicle fires in parking structures developing into large conflagrations are rare but can result in severe economic losses. It is important to understand the hazard posed by modern vehicle fires to determine whether current fire codes for parking garages are mandating adequate fire protection requirements. There has been an increase in the fire hazard from changes in vehicle design and increased use of plastics and other combustible materials in vehicle construction, along with denser parking of vehicles in parking structures. This manifests as faster flame spread within the vehicle, easier ignition and more rapid fire spread to neighboring vehicles. Based on the findings, test data from vehicles older than 2000–2005 model years should not be used as basis for development of codes and regulations. Open parking structures emerge as the main area of concern regarding fires in modern vehicles. The lack of any requirements for active protection systems in the fire codes, and trends in vehicle and garage design suggest that large, devastating fires in these structures could become increasingly common. The spread of fire between vehicles, especially from the initial to the second and third vehicles, is critical in determining the extent of the fire and the ability of the fire department to successfully control and extinguish. Future research should be conducted into earlier detection, sprinkler protection, and fire spread between vehicles to address the hazard.

停车处大面积起火的车辆起火很少，但会导致严重的经济损失。重要的是要了解现代车辆起火带来的危害，以确定当前的停车场消防法规是否规定了足够的防火要求。车辆设计的变化以及车辆结构中塑料和其他可燃材料的使用增加，以及车辆在停放结构中的密集停放，都增加了火灾隐患。这表现为更快的火焰在车辆内传播，更容易的点火以及更迅速的火势蔓延到附近的车辆。根据调查结果，不应将2000-2005车型年以上的车辆的测试数据用作制定法规的基础。开放式停车结构成为现代汽车着火的主要关注领域。防火规范中对主动防护系统的要求不高，并且车辆和车库设计的趋势表明，这些结构中的大型毁灭性火灾可能会变得越来越普遍。车辆之间（尤其是从最初的车辆到第二和第三辆车辆）之间的火势蔓延对于确定火势以及消防部门成功控制和灭火的能力至关重要。未来的研究应该针对早期发现，洒水装置的保护以及车辆之间的火势蔓延，以解决这一危害。这些建筑物中的毁灭性大火可能会变得越来越普遍。车辆之间（尤其是从最初的车辆到第二和第三辆车辆）之间的火势蔓延对于确定火势以及消防部门成功控制和灭火的能力至关重要。未来的研究应该针对早期发现，洒水装置的保护以及车辆之间的火势蔓延，以解决这一危害。这些建筑物中的毁灭性大火可能会变得越来越普遍。车辆之间（尤其是从最初的车辆到第二和第三辆车辆）之间的火势蔓延对于确定火势以及消防部门成功控制和灭火的能力至关重要。未来的研究应该针对早期发现，洒水装置的保护以及车辆之间的火势蔓延，以解决这一危害。
