Nashville, TN — At the 2026 Annual Meeting and Transportation Technology Exhibition held on September 8, the Technology & Maintenance Council (TMC), a division of the American Trucking Association (ATA), presented its coveted Silver Spark Plug award to four professionals who have reshaped truck maintenance and technology nationwide.
The Silver Spark Plug stands as TMC’s highest individual accolade, reserved for those who deliver lasting contributions to commercial vehicle upkeep and innovation. “The Silver Spark Plug is given to individuals who demonstrate professional excellence in commercial vehicle maintenance as our industry’s highest honor,” said TMC Executive Director Robert Braswell. “Our winners this year represent the highest level of expertise and ability in our industry. We are pleased to recognize them with this award.”
Recipients span a spectrum of roles: Scott Bartlein of Truck Fleet Management, Taki Darakos from PITT OHIO, Mark Zachos of DG Technologies, and Jack Legler, a senior leader at TMC/ATA. Each has pioneered solutions that reduce downtime, lower operating costs, and elevate safety across fleets of all sizes.
What This Means for Drivers
For CDL‑A holders and owner‑operators, the award highlights the importance of reliable diagnostic tools and maintenance protocols that keep rigs on the road longer. Bartlein’s work in predictive analytics now helps fleets forecast component wear, cutting unplanned repairs by up to 15 percent. Darakos’s development of rapid‑diagnosis software streamlines troubleshooting, allowing drivers to return to duty faster after a roadside issue. Zachos’s innovations in engine health monitoring translate into smoother power delivery, reducing fuel consumption and improving route efficiency. Legler’s leadership in TMC’s technical standards ensures that new regulations from FMCSA are met without compromising performance.
Industry Reaction
ATA President and CEO Chris Spear emphasized the broader impact of these professionals. “TMC’s members keep our industry moving, and these four individuals represent the highest level of professional excellence the council strives for,” Spear said. “More than half of the 8.4 million people employed by the trucking industry do something other than drive a truck, and without them, our nation’s goods would not be delivered to our stores, hospitals, and factories.” Spear’s remarks underscore how maintenance expertise directly supports the supply chain, benefiting every OTR truck driver and regional carrier.
