Crashes or accidents involving commercial motor vehicles (CMVs) can be costly in many ways, and they usually trigger a series of actions to be taken. Some of those actions are required by laws and regulations, and some are recommended to mitigate risk.

A variety of federal, state, and local laws and regulations require motor carriers and drivers to track and report accidents. Although motor carriers are not required to investigate accidents, investigations are recommended as a way to find the cause, reduce liability, and/or prevent future crashes.
