NASHVILLE, Tenn. — Four members of American Trucking Associations’ Technology & Maintenance Council have been awarded the organization’s highest honor — the Silver Spark Plug.

“The Silver Spark Plug recognizes individuals in our industry who are making outstanding contributions to the improvement of equipment, maintenance, industry-related technology and management practices,” said Carl Kirk, TMC’s executive director.
