The drive recorder was originally introduced to proceed with investigation of the causes and negotiations promptly after a taxi becomes involved in an accident; however, due to its secondary effects, it is now used for improving driving manners of the drivers, presenting evidence for a crime or accidents in which the taxi was not the party in charge, and preventing accidents by analyzing the cause of the accident.
当初は、タクシーの事故後の解決･交渉をスムーズに進めるために導入されたが、副次的な成果として、ドライバーの運転マナーの向上やタクシーが当事者ではない事件や事故の証拠、事故原因の解析による事故予防などに活用されている。
