Motor Carrier Policy — a commercial auto policy introduced by Insurance Services Office, Inc. (ISO), in 1993 to address the needs of the motor carrier (i.e., trucking) industry. Coverages available include auto liability, trailer interchange, and auto physical damage; other coverages are available by endorsement. The policy was developed as an alternative to the truckers policy because of the changes taking place in the industry. That is, the truckers policy is applicable only for "for-hire" motor carriers, whereas the motor carrier policy is appropriate for all types of motor carriers—for-hire, private, or a combination of both types of operations.
