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.
