Definition

A collision is an accident in which two or more things hit each other.

A collision happens when moving objects come into contact, often suddenly and with force. It is commonly used for road accidents involving vehicles, but it can also describe any impact between objects. In more formal contexts, it can refer to a serious crash that causes damage or injury.

Examples

  • I slowed down immediately after the collision and checked that everyone was safe.
  • You could hear the collision from the other end of the corridor when the trolley hit the door.
  • He described the collision as a brief lapse in attention that had serious consequences.
  • They reported the collision to campus security and took photos of the damaged bikes.

Common mistake

Learners sometimes confuse collision (an impact) with collusion (secret cooperation), even though they sound similar and have different meanings.
