American Service Insurance Company v. Jones 

(Court opinion corrected 5/7/10). Insurance company insured moving company's two trucks. Moving company rented a truck from a rental company and was in collision in Illinois while en route from Illinois to Indiana, injuring a third party. Jurisdiction of ILCC is not limited solely to intrastate commerce, and extends to motor carriers of property. Cartage of household goods is within activities regulated by Transportation Act, thus moving company's policy with its insurer provides coverage. Rental company's policy provides primary coverage for public policy reasons, because rental company failed to offer moving company the choice of primary coverage; but moving company's insurer also provided primary coverage, thus two "excess" clauses cancel each other out, and loss is prorated between policies.
