The monthly loop, by hand
Everything below is free and public. For each carrier, once a month:
- Pull the SAFER company snapshot. Check operating status and authority, the safety rating and its date, and the MCS-150 date. Carriers are required to refresh that filing every two years, and a stale one says something about the back office.
- Pull the SMS page.Look at each safety category’s measure, the inspection and violation counts, and the carrier’s out-of-service rates next to the national averages shown on the page. Percentiles for property carriers are hidden by law, so the trend in the measure is your signal.
- Check insurance and authority filings on L&I. Liability coverage on file, pending cancellations, and authority actions live here, and they move on their own schedule.
Then write down what you saw, with the date. Next month, do it again and compare.
The changes worth reacting to
- A safety-category measure that climbs several months in a row. With percentiles masked, the trend is the tell.
- An out-of-service rate sitting above the national average.
- A new Conditional (or worse) safety rating.
- A cancellation notice against the liability filing.
- An authority status change, especially an involuntary revocation.
- An MCS-150 more than two years old.
Keep a dated record
When a renewal turns contentious, the question is rarely “what does the data say today.” It’s “what did the public record show at the time, and did anyone look.” A dated note each month answers that. Screenshots work; so does an export you can drop in the client file.
The math on doing this yourself
Three lookups per carrier, once a month. A hundred-carrier book is three hundred lookups plus notes. Call it a full workday, every month, of copying numbers between government tabs. Which is why most desks check a carrier exactly once: at renewal. That’s also the one moment it’s too late to get ahead of anything.
Automating the loop
This is the whole product at CSA Sentry: import your book once, and every carrier gets checked against each monthly FMCSA release for safety data, rating, authority, and insurance on file. When something moves, you get an email in renewal language, not a dashboard to babysit. Every alert lands in a dated record you can export.
It’s the same public data you could pull by hand. What you’re buying is never missing a month. From $49 for a solo book, no card to start.
Quick answers
How often does the data change? SMS republishes monthly. SAFER and insurance filings update on their own, faster schedules, which is why authority and insurance are worth checking alongside the safety data.
Does a high score mean the carrier is unsafe? No. FMCSA itself says not to draw conclusions about a carrier’s overall safety condition from SMS data, and a carrier is authorized to operate unless FMCSA has ordered otherwise. More on what the scores do and don’t say.
Can a carrier’s numbers improve on their own? Yes. Events age out of the 24-month window and count less as they get older, so a clean stretch pulls measures down. Carriers can also dispute data they believe is wrong through FMCSA’s DataQs process.
