A reportable crash is defined as a crash resulting in injury or death of any person, any damage to
government-owned non-vehicle property to an apparent extent of $200 or more, or total damage to
property owned by any one person to an apparent extent of $1000 or more. (This definition went into
effect 1/1/96). It is important to note, however, that not all reportable crashes are reported. In order
for a crash to be in the database, an MV4000 crash report must have been completed by a police officer.
