Our Journalists
Meet the expert voices behind the Transportation Safety Alliance. Each brings decades of real-world trucking experience to their reporting.
Jack Sullivan
Jack Sullivan spent 25 years behind the wheel of a Class 8 rig, logging over 3 million safe miles across all 48 contiguous states before transitioning to journalism. A former owner-operator who ran his own authority for a decade, Jack knows the trucking life from the inside out — the long nights, the tight deadlines, the camaraderie at truck stops, and the constant battle to stay safe on America's highways. Now he channels that hard-won experience into reporting that puts drivers first. Jack covers equipment reviews, truck stop culture, driver health and wellness, and the real-world impact of industry changes on the men and women who keep freight moving. His writing is direct, no-nonsense, and always grounded in the perspective of someone who has lived the life he writes about.
"Keep the shiny side up and the rubber side down."
Marcus Vance
Marcus Vance holds a Master's degree in Supply Chain Management from Michigan State University and spent 15 years as a fleet operations manager for a mid-sized carrier in the Midwest before joining the Transportation Safety Alliance. During his career in fleet management, Marcus oversaw a fleet of 200+ trucks, negotiated broker contracts, optimized fuel purchasing strategies, and guided his company through two economic downturns without a single layoff. He brings that same analytical rigor and business acumen to his journalism. Marcus specializes in breaking down complex economic trends, freight market dynamics, and fleet management strategies into actionable intelligence for owner-operators and small fleet owners. Whether it's analyzing spot rate fluctuations, evaluating fuel hedging strategies, or explaining how new tariffs will impact the bottom line, Marcus delivers the numbers that matter — and explains what they mean for your business.
"Drive the data, not just the truck."
Sarah Jenkins
Sarah Jenkins is a former DOT compliance officer and FMCSA inspector who spent 12 years on the enforcement side of trucking regulations before making the switch to journalism. During her time with the Department of Transportation, Sarah conducted thousands of roadside inspections, participated in carrier audits, and helped draft enforcement guidance for new regulations including the ELD mandate. She holds a J.D. from Georgetown University Law Center with a focus on transportation law. Now at the Transportation Safety Alliance, Sarah uses her insider knowledge to help drivers and fleet owners navigate the complex web of federal and state regulations. She translates dense legal language into plain English, explains the real-world enforcement priorities behind the rules, and provides practical compliance strategies that keep drivers on the road and out of trouble. When FMCSA announces a new rule, Sarah is the first to break down exactly what it means for you.
"Stay compliant, stay safe, and keep rolling."
