This can happen in various situations, such as car accidents on the road, where vehicles like cars or trucks hit one another. Collisions can also occur in sports, like when players collide during a game of football or hockey. The impact of a crash can lead to serious consequences, including injuries to people involved and damage to property. In the case of vehicle collisions, safety measures like seat belts and airbags are designed to protect passengers.
