Summary: The Insurance Services Office (ISO) offers the motor carrier coverage form, CA 00 20 10 13, as an alternative to the truckers coverage form which is being phased out by ISO. The motor carrier form is meant to act as an underwriting tool for those companies that have insureds who have been affected to some degree by the changes that have occurred over the past several years in the trucking industry. (As noted by ISO, major reasons for changes include “the enactment of the Motor Carrier Act, reduced regulatory authority of the Interstate Commerce Commission . . . and the increased activity of the private carrier industry in common and contract carrier business.”) The following discussion centers on the symbols that are used to describe covered autos under CA 00 20.

Topics covered:

Acquired autos



 The motor carrier coverage form follows in many respects the language of the truckers coverage form. As befits its purpose, however, the motor carrier form does present different provisions from the truckers form so as to fit coverage more precisely to the loss exposures faced by today’s common, contract, and private motor carriers.
