For the data basis of my diploma thesis, I need additional literature, statistics, case studies, etc., on the above-mentioned topic. The subject deals with blocks or sheets of ice falling from trucks or semi-trailers, which can hit passenger cars and cause property and/or personal damage. Since the data available online is very limited and even insurance companies have only provided me with insufficient information, I am hoping for insider knowledge regarding existing literature, papers, or reports. The sources I am currently aware of refer only to the ADAC, DEKRA, or recommendation letters from insurance companies. I have already found some information regarding preventive measures. Thank you very much for your support.
