practices is a major focus, there are many other benefi ts of being a member. For example, TMC members enjoy a wide range of discounts on fuels, tires and new and used trucks through the TruckersB2B program. Also, TMC’s technical staff produces numerous publications and periodicals to keep members up-todate on trucking industry regulations and maintenance parts recalls. Th e primary focus of TMC’s staff and working members is to increase effi ciencies in the upkeep of heavy duty equipment and that goal is accomplished every day with better training, clearly written manuals and network opportunities. If you have trucks and you aren’t a TMC member, then you’re working harder than you have to. For more information, or to join TMC, go to http://jointmc.trucking. org or email tmc.trucking.org. Janet Howells-Tierney serves as the director of council development for TMC (www.trucking.org/Technology_Council. aspx) – the only industry association that is focused solely on truck technology and maintenance. She is responsible for the recruiting and building of TMC membership, and also functions as the communications link for TMC for Council activity.
