TMC Recommended Practices enter appeal period

For MOTOR Information
Systems, the VMRS
Codes are important
in our ongoing effort
to standardize parts,
labor, and service
information across all
types of vehicles from
passenger car to tractor
trailers and beyond."
Paul Moszak, TMC's VMRS
Codes Committee Chairman

An important aspect of VMRS is its ability to
provide data for measuring the performance and
reliability of specific components used for benchmarking studies. In 2018, TMC partnered with
Fleetnet America, headquartered in Cherryville,
North Carolina, to provide a unique TMC fleet
member benefit. TMC fleet members receive a
quarterly roadside breakdown benchmarking
report that is based on VMRS System codes.
Participants in the study have access to a digital
dashboard that provides real-time data allowing
them to compare their breakdown data with other
participating fleets.
There have been a multitude of changes in the
trucking/transportation industry in the past 50
years, and VMRS has been there as an important
part of equipment maintenance. Fleet managers
have always relied on VMRS to provide them
with the best method for producing maintenance
reports, so it's imperative that VMRS contains
codes for the latest technologies.
"For MOTOR Information Systems, the VMRS
Codes are important in our ongoing effort to
standardize parts, labor, and service information
across all types of vehicles from passenger car to
tractor trailers and beyond," said Paul Moszak,
TMC's VMRS Codes Committee Chairman.
Equipment maintenance has seen a lot of changes over the years, but VMRS is still the tried and
true method of tracking maintenance repairs.
VMRS will continue to chart new horizons as
equipment maintenance continues to evolve.
VMRS will be there for future generations as it
has for the past 50 years.
JACK POSTER, TMC's VMRS
Services Manager, has worked in
the transportation industry for
more than 30 years. His family
owned a Chrysler-Plymouth agency
in Western Pennsylvania. After college, Poster returned to help run
the dealership. Later, he worked
for Merchant's Tire & Auto. After
19 years with Merchant's, he took
a position with Mancon Inc. and became familiar with
VMRS. In 2007, he left Mancon to become TMC's VMRS
Services Manager.
