Computers A garbled communication between 2 devices in a local area network (LAN) that results when both attempt to transmit data simultaneously; after colliding, each device waits for a period of time and retries; increased devices on a LAN increase the likelihood of collision
Obstetrics A mechanical obstruction to the birth of twins, such that the lay of one foetus impedes the engagement of the other; the most extreme collision is known as interlocking
Public health Road traffic accident/motor vehicle accident
