As part of the extension a few requirements have been added specifically:

A motor carrier whose driver is involved in a crash while operating under this emergency declaration must report any recordable crash within 24 hours, by phone or in writing, to the FMCSA Division Office where the motor carrier is domiciled. The carrier must report the date, time, location, driver, vehicle identification, and brief description of the crash.

Since, solid waste and medical waste is covered in the FAQs, it appears that we need to report all crashes to FMCSA.
