A pile-up is a car accident involving multiple vehicles that crash into each other, often in a chain reaction. This typically happens on highways or busy roads where cars are driving closely together. A pile-up can be caused by sudden braking, poor weather conditions, or visibility issues. The cars involved may end up tangled together, leading to significant damage and often blocking traffic. Pile-ups can be dangerous, as the risk of injury increases due to the number of vehicles involved and the force of the collisions.
