What Are the Key Differences Between Chubb and Liberty Mutual Commercial Auto Insurance?

Vehicle and Employee Endorsements

Chubb describes a Commercial Auto Broad Form endorsement that can add broad-form-insured and fellow-employee coverage where allowed, rented-auto coverage for employees, and auto loan or lease gap coverage. Liberty Mutual says its underwriters tailor solutions to industry, fleet, location, and vehicle use. If employees rent vehicles or the business finances high-value vehicles, compare the specific endorsement language and confirm which vehicles and insured parties appear in each proposal. [2] [6]

Limit Scope and Tailored Fleet Terms

Chubb states that its small-business Total Account Solution includes PIP and uninsured/underinsured motorist limits up to $1 million when commercial auto is bundled; that figure is scoped to the bundle, not its standalone auto page. Liberty Mutual describes underwriting tailored by fleet, industry, location, and use. Buyers should compare bundled with bundled or standalone with standalone proposals and verify the applicable PIP and UM/UIM limits in the declarations. [3] [2] [6]

What Should You Confirm in Chubb and Liberty Mutual Commercial Auto Insurance Quotes?

  • Ask Chubb whether its Total Account Solution applies and which PIP and UM/UIM limits and endorsements are quoted. [3]
  • Ask Liberty Mutual how fleet, location, industry, and use affect the vehicle schedule and proposed liability terms. [6]
  • Compare hired-auto terms, fellow-employee coverage, deductibles, and exclusions in the final forms. [2] [6]
