Final answer:
Over-correction crashes involving multiple vehicles occur when a driver abruptly tries to correct their vehicle's trajectory after losing control. This can lead to a chain reaction of collisions as other drivers react to the sudden change.
Step-by-step explanation:
In collisions involving multiple vehicles, over-correction can lead to a chain reaction of collisions. When a driver tries to correct their vehicle's trajectory abruptly after losing control, they may over-steer, causing their vehicle to swing in the opposite direction. This sudden change can catch other drivers off guard, leading to subsequent collisions involving multiple vehicles.
For example, if a driver loses control of their car and swerves to the right, but over-corrects by quickly turning the steering wheel to the left, the car may end up swinging across to the left side of the road, potentially colliding with oncoming vehicles or other vehicles that were already present in that lane.
Over-correction crashes often involve a chain reaction because when one vehicle swerves or loses control, other drivers nearby may instinctively react, resulting in a series of collisions. These multiple collisions can occur simultaneously or sequentially, depending on the specific circumstances of the accident.
