The scene of the scene of a series of car crashes in the snowy days of Pennsylvania, USA

On the 28th local time, Pennsylvania suffered a spring snowstorm. At least three people were killed and about 20 injured after dozens of vehicles collided on a stretch of state highway.
The video shows a tractor-trailer colliding with a large truck, with its nose turning nearly 180 degrees. An SUV rammed into a sedan, spinning the sedan, nearly hitting the driver who was standing on the shoulder of the road. More than 50 vehicles, including large cargo trucks, were involved in the crash, some of which caught fire, the emergency management agency said. Blizzard weather may be the reason for the rear-end collision.
