Enter the Manner of Collision code for the vehicles involved in the initial or first collision.
The identification of the manner in which two motor vehicles in transport initially came together without regard to the direction of force. This data element refers only to crashes where the first harmful event involves a collision between two motor vehicles in transport.
This element is important for evaluating occupant injuries and structural defects.
- If First Harmful Event does not indicate collision with a motor vehicle in operation or parked, then Manner of Collision should be ‘single vehicle crash’.
- If the value recorded for Number of Vehicles is ‘one’, then Manner of Collision should be ‘single vehicle crash’.
- If Vehicle Travel Direction indicates that the vehicles were traveling in the same direction, then Manner of Collision cannot be ‘head on’, ‘sideswipe opposite direction’, or ‘rear to rear.’
- If Vehicle Travel Direction indicates that the vehicles were traveling in opposing directions, then Manner of Collision cannot be ‘rear-end’ or ‘sideswipe same direction’.
- If Vehicle Travel Direction indicates that the vehicles were traveling perpendicular to one another, then Manner of Collision must be ‘head-on’ or ‘angle’.
