What Are the Key Differences Between CNA and THREE by Berkshire Hathaway Commercial Auto Insurance?

Standalone Detail or Combined Package

CNA's commercial-auto record states liability coverage for owned, hired and non-owned business vehicles and separately lists automobile physical damage. THREE presents Business Auto as one part of its combined Business Owners Policy rather than as a standalone product in the reviewed overview. A buyer seeking auto alongside other small-business protections can explore THREE's package route; CNA's record provides more detail on vehicle scope. [5] [5] [1] [1]

CNA names Driver Distractions and Cargo Securement programs with claims support.
