Danger is a situation that threatens the existence and security of a per-son or an object and indicates a possibility of damage. The sequential relationship established between these concepts has important results from the point of the applicability of provisions on aggregation of of-fences, and especially for endangerment and damage offences. When the case law of the “Supreme Court” is examined, a change of under-standing is identified. Previously, if the offence of “intentionally endan-gering traffic safety” and the offence of “reckless injury” were commit-ted by one single act, provision on conceptual aggregation was applied. Recently, it is considered pursuant to the primarysecondary norm rela-tionship. In this study, the related concepts, the issue of how to apply provisions on aggregation for these offences, considering the case law of the Supreme Court, and results of the change in case law, in the concept of reconciliation will be examined.
