MAXIMUM ENGAGEMENT – it is the greatest collapse or overlap in a collision; the force between the traffic unit and the object collided with are greatest at maximum engagement
DISENGAGEMENT – it is the separation of a traffic unit in motion from an object with which it has collided; the force between the object ceases at this time
STOPPING – this is when the traffic units involved come to rest; it usually stabilizes the accident situation
INJURY – it is receiving bodily harm; this event does not necessarily occur after the accident but within any of the chain of events; it may also happen right after the evasive action taken by the drivers involved or during the initial contact

HAZARD -  a hazard is generated when a critical space-motion relationships between a traffic unit and another object develops due to the movement of either or both (ex. A curve in the path is a hazard; another traffic unit in the path is a hazard.)
SAFE SPEED – the speed adjusted to the potential or possible hazards or the road and traffic situation ahead; safe speed on the road is determined by the road rather than the particular driver of a vehicle (ex. A curve ahead is a hazard and a safe speed for it is a speed at which it can be taken comfortably
