The road to success can be deadly. In the second season of IRT DEADLIEST ROADS, Lisa, Hugh and Rick, three of the toughest North American truckers, are driven to extremes in one of the worlds most unforgiving environments: the Andes. As they cross borders to navigate the highways of South America, this fearless trio encounters some of the deadliest roads in history. Everything theyve learned in more than 40 years of combined experience is tested in nerve-rattling conditions theyve never experienced before. Whether its driving along 1,000-foot cliffs or dodging avalanches, skill and ingenuity go full-throttle.
