Traffic accident certificates are issued on request from the parties involved in an accident. They state the date and time of the accident, the names and addresses of the parties involved, and other relevant details.
　JSDC certifies these details based on data kept by the police. Among others, these certificates are used as supporting documents when claiming various kinds of automobile insurance benefits.
　The certificates are prepared using personal information held by the police. As such, applications are only accepted from a party involved in a traffic accident (either at-fault or non-fault), or someone applying on their behalf by proxy.
