You see them on the highway everyday, but today, truckers who roam from state to state found themselves parked. They were taking a different kind of ride--a virtual ride. It's a "big rig" that's basically a video game to teach trucker driver safety. At the touch of a button, several scenarios can happen from a tire blowout to severe fog conditions. The uniqueness of the simulator stems from the motion based cab. The truck is funded and provided by a grant from TxDot.
