Key Differences in Commercial Auto Insurance

Truck fleet thresholds versus general business vehicles

AIG names a narrow trucking profile: heavy vehicles above 26,000 pounds, 11–250 power units, predominantly Class A/B CDL drivers, and at least four years in operation. Nationwide describes liability for businesses using cars, trucks, vans, and other vehicles, without publishing a comparable fleet or experience threshold in the reviewed product description. A fleet outside AIG’s stated profile should ask Nationwide for the actual vehicle and industry eligibility rules. 3 7

Published product detail and access route

AIG lists admitted auto liability and physical-damage products for its for-hire trucking segment and works through select brokers. Nationwide’s cited page describes injury and property-damage liability from business driving, then directs prospects to an agent or quote request; it does not establish physical-damage terms. Ask each provider to specify which coverages appear on the proposed policy, rather than assuming the broad product descriptions settle that question. 3 7

What to Confirm in Commercial Auto Insurance Quotes

  • For AIG, confirm whether your vehicle weights, fleet size, driver mix, and operating history fit the select-broker program. 3
  • For Nationwide, request the proposed physical-damage options and the policy limits, exclusions, and state-specific terms. 7
