Our Verdict

Great West Casualty wins for fleets that want an insurer completely dedicated to trucking. Their safety programs, specialized claims handling, and 100% trucking focus provide a level of industry expertise that generalist insurers cannot match.

Sentry Insurance wins for fleets that want competitive pricing and the stability of a large, diversified insurer. Their broader book of business can sometimes produce more competitive rates, especially for fleets with clean records.

For most trucking operations, the trucking specialist is the better choice. Insurance is too important to leave to a company that treats trucking as a side business.

Frequently Asked Questions

No, Great West Casualty insures fleets as small as 5 trucks. However, they are particularly strong in the 20-500 truck segment where their safety programs and fleet-level pricing provide the most value.
Sentry offers safety discounts but they are not as comprehensive as Great West's safety program-based discounts. Great West ties premium reductions directly to participation in their safety training and fleet evaluation programs.
Great West's cargo claims expertise is superior due to their exclusive trucking focus. Their adjusters understand common cargo claim scenarios, shipper/carrier disputes, and temperature-sensitive cargo issues at a level that generalist adjusters typically do not.
