The Complete Guide to Vetting Freight Carriers in 2026

Choosing the wrong carrier doesn't just mean a delayed shipment. It can mean damaged freight, a compliance violation, or worse, an accident involving an unqualified driver. Carrier vetting isn't a formality — it's risk management.

Here's the framework we recommend for shippers and brokers looking to build a reliable carrier network.

Start with FMCSA. Every carrier operating in the US must be registered with the Federal Motor Carrier Safety Administration. Pull their DOT number, check their operating authority status, and review their safety rating. Carriers with a "Conditional" or "Unsatisfactory" rating are a red flag. Also check their out-of-service rates for vehicles and drivers — anything consistently above the national average warrants a deeper look.

Verify insurance. Carriers must carry minimum liability coverage, but minimums aren't always enough. For high-value freight, confirm that cargo insurance limits are appropriate for your load. Ask for a certificate of insurance and verify it directly with the carrier's insurer rather than relying on a copy that could be outdated.

Check for recent violations and crashes. FMCSA's Safety Measurement System (SMS) publishes carrier violation data. Look for patterns — repeated hours-of-service violations, brake inspection failures, or cargo securement deficiencies are worth a conversation before you tender a load.

Review their performance history. On FreightBidder, verified carriers accumulate ratings from actual shippers based on on-time performance, communication, and cargo handling. A carrier with fifty five-star reviews is telling you something a DOT database can't: that real operators trust them.

Run this process before a carrier's first load, and spot-check it annually. A carrier's safety record can change. The ones worth working with long-term will have nothing to hide.
