SpecStream is the live web data engine for teams and agents. It reads the carrier register, roadside inspections, crashes and operating authority that FMCSA publishes, and this page is that reading. Ask for the carriers you sell to or insure by state, city, cargo or fleet size, and new inspections, crashes and authority changes arrive in your sheet, CRM, Slack or agent as FMCSA posts them.

Fleet size, drivers, cargo and operation are as each carrier reports them to FMCSA and can be out of date. A vehicle or driver out of service order means an inspector ordered the vehicle or driver off the road until the problem was fixed. The national rate comes from every inspection in the same window. Crashes are those state police reported to FMCSA and are not a finding of fault.
