Ruhl Forensic Leader in Forensic Technology

Ruhl Forensic was asked by the trucking company to determine the cause of this single vehicle crash.


Thorough tire and wheel examinations can help determine if the tire failed before the crash or as a result of it.


Temporary traffic control zones, even when done properly, can confront motorists with unexpected and confusing situations. When done improperly the results can be dire.
