How a rating is produced
A rating does not come from roadside inspections or from an algorithm. It follows a compliance review: an investigator examines the carrier's records — driver qualification files, hours-of-service documentation, drug and alcohol testing programme, maintenance records, accident register — and evaluates them against defined factors. The result is one of three ratings, or none at all if no review has occurred.
| Rating | Meaning | Effect on operations |
|---|---|---|
| Satisfactory | The carrier met the standard at the time of review. | None. Normal operation. |
| Conditional | Deficiencies found, but not severe enough to prohibit operation. | None legally. The carrier may continue to operate. |
| Unsatisfactory | Serious deficiencies identified. | Operation is normally prohibited once the notice period expires. |
| Unrated | No compliance review has taken place. | None. Neutral status. |
Why "unrated" is the norm
There are far more registered carriers than there is investigative capacity to review them. Reviews are prioritised by risk indicators, complaints and crash involvement, which means the majority of carriers — including a great many small, long-established, entirely unremarkable ones — never receive a rating.
Reading an empty rating field as a red flag inverts its meaning. It signals absence of a review, not absence of compliance.
Conditional is widely misunderstood
A Conditional rating is frequently treated as disqualifying. Legally it is not: a Conditional carrier retains authority and may haul. It indicates that specific deficiencies were documented and that the carrier fell short on one or more factors, which is meaningful information — but it is a finding about a point in time, not a permanent verdict.
Individual companies are free to apply stricter internal standards than the federal minimum, and many do. That is a commercial policy choice and should be described as such rather than presented as a regulatory requirement.
Ratings can be changed
A carrier may request an administrative review where it believes a rating was based on incorrect data, and may request an upgrade after submitting evidence of corrective action. Both processes take time, and the public record shows the current rating rather than the history of how it was reached.
Rating versus percentile
Ratings and BASIC percentiles measure different things and are produced by different processes. A carrier can hold a Satisfactory rating from a review several years ago while currently showing elevated percentiles from recent roadside inspections, or the reverse. Neither supersedes the other. The BASIC scores page covers the percentile side.
