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.
