Listen to most recent episode of Road Signs





One hundred episodes. Over one hundred guests. And, most importantly, one hundred critical trucking questions... answered. The first episode of RoadSigns asked, "Autonomous: Who's Behind the Wheel of Tomorrow?" To answer, Seth Clevenger brought in Alex Rodrigues of Embark who was just starting off in the autonomous trucking sector. Two rookies tackling the biggest question of their time and setting the stage for the future. Now, four years later, we've acquired an entire roster of extraordinary guests in tech, autonomous trucking, workforce development and trucking equipment, along with an irreplaceable co-host, Michael Freeze. For the next 30 minutes, see where trucking was in 2018, where it's going in 2023, and how RoadSigns podcast has enjoyed every minute in between — helping you, our listeners, navigate the trucking road ahead.
