Key Differences in Commercial Auto Insurance

For-hire trucking criteria versus rental-fleet coverage

AIG names for-hire trucking companies with vehicles over 26,000 pounds, 11–250 power units, predominantly Class A/B drivers, and at least four years operating. Zurich’s reviewed commercial-auto material is specifically about rental fleets, with state financial-responsibility liability, uninsured/underinsured motorist, and no-fault personal-injury-protection options. A rental operator should compare Zurich’s specialized terms; other trucking businesses should not assume those rental-fleet terms apply to them. 3 6

Underwriting information and physical damage

AIG says buyers access its trucking products through select brokers and describes related fleet-safety and DOT-compliance services. Zurich takes applications by phone and asks about fleet size, vehicle age, value and type, rental use, personal use, customer transport, and operating procedures. Zurich also describes specified-peril, comprehensive, and collision options for rental fleets, with stated limits on its catastrophic option. Bring these operational details to the quote discussion and ask which causes of loss are covered. 3 6

What to Confirm in Commercial Auto Insurance Quotes

  • Ask AIG’s broker to confirm the underwriting entity and available deductibles for your fleet profile. 3
  • Ask Zurich whether its rental-fleet form fits your use, and request the catastrophic option’s trigger and exclusions in writing. 6

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.[1][2]

Review Score

The available Zurich review evidence is mixed and comes from distinct populations: a car-rental-business editorial rating, broad global and U.S. review-platform snapshots, and a BBB business-profile grade. These are not a representative measure of every Zurich commercial policy or claim.[1][4][5][6][7]
