###### *How does PRISM affect IRP registration?*

IRP serves as the framework for the PRISM program. The USDOT number of
the motor carrier responsible for the safety of every vehicle registered
must be identified during the registration process as well as the USDOT
Number of the registrant. Additionally, an updated MCS-150 form for each
identified motor carrier responsible for safety on an IRP account and an
updated MCS-150 form for the registrant is required unless the motor
carrier and the registrant have each submitted one within 12 months
prior to the first day of the renewal period or have updated the
information directly on the FMCSA web page http://www.fmcsa.dot.gov.

In many of the IRP accounts, the registrant that maintains the IRP
account and the motor carrier that is responsible for safety are the
same. Table A outlines USDOT Number and MCS-150 update requirements
associated with PRISM and IRP registration in these instances.

In some cases though, the IRP account registrant and the motor carrier
responsible for the safety of individual vehicles on the account may be
different. The following examples and Table B outline USDOT Number and
MCS-150 update requirements associated with PRISM and IRP registration
in common instances.

Rental/leasing companies who register in the rental/leasing company
name.

Rental/leasing companies who register in their own name must provide the
USDOT Numbers and copies of updated MCS-150 forms to the registration
office for the rental/leasing company and also for all lessees who are
responsible for safety for the vehicles. The USDOT Number for the
rental/leasing company should be recorded in Section C of the IRP
Schedule A and the appropriate USDOT number for the lessee's must be
recorded in column 21. Column 22 must be recorded with an "n" if the
terms of the lease cover the full registration year.

Owner/Operators registering in their own name that lease to motor
carriers

Owner/operators who register in their own names must obtain a USDOT
Number for themselves. This number is for registration purposes only and
does not provide the owner/operator with his/her own operating
authority. In addition, the owner/operator must provide the USDOT Number
for the company to whom he/she leases. Updated copies of the MCS --150
must be submitted for the owner/operator and all companies responsible
for safety (the lessees). The MCS --150 forms for the companies must be
completed by the companies. The owner/operator must record his/her USDOT
Number in Section C of the IRP Schedule A. Column 21 should be completed
with the USDOT Number of the motor carrier responsible for safety.
Column 22 should indicate whether the term of the lease is as long as
the registration year.

Companies who use all leased vehicles registered in the name of the
lessors.

Companies who use all leased vehicles registered in the name of the
lessors (rental/leasing or owner/operators) must provide the lessor with
an updated copy of the MCS-150. The lessor will submit it to the state
registration office in order to have the vehicle's registration renewed.
