Central Analysis Bureau has rated motor carriers for roughly 75 years. When a trucking submission reaches an underwriter at almost any insurer or MGA, they pull the CAB report before anything else: safety record, authority and insurance history, finances, equipment, and CAB’s own scores and alerts.
It has real teeth. Some insurers weigh CAB scores more heavily than the fleet’s actual claims history, and a couple of CAB alerts can get a risk declined outright. If you write trucking, the CAB report is not a competitor to work around — it is part of the market’s plumbing.
The catch: CAB reports are available exclusively to CAB subscribers, and subscriptions are sold through their team with unpublished pricing. Which is usually why you are here.
A CAB report fuses two kinds of data. The federal layer is public — you can see it free, today, without anyone’s permission. The proprietary layer is why underwriters pay for CAB, and there is no free equivalent for it anywhere.
FOOTNOTE CAB details from cabadvantage.com, IRMI’s definition of a CAB report and FreightWaves’ CAB profile, as of August 1, 2026. CAB and Central Analysis Bureau are products of their respective owner (Fusable); Native Base is not affiliated with either. Corrections: hello@nativebase.ai.
If you underwrite, you need CAB — full stop. But most people searching for a CAB report are producers, and a producer’s day is prospecting: which carriers renew soon, who just lost coverage, who to call. That is a different job, and it does not need an underwriting bureau.
