When a severe traffic accident occurs, in which many vehicles are involved and many persons are killed or severely injured, when it can be called a disaster which shocks society, there should be a thorough investigation of the accident. The whole accident process, not just the outcome must be studied by means of different theoretical approaches. The study must be a methodological pilot study, in which the set up of the thorough investigation should be the central point. A protocol for the experiment of such an accident investigation must be made. The protocol has to provide a framework for working with a limited theoretical aim. A working group should make an inventory of the existing protocols on a short term. A literature review is made and the results are presented. On the basis of other information, a description is given of data which can be important for such a thorough traffic accident investigation.
