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 world's 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 they’ve learned in more than 40 years of combined experience is tested in nerve-rattling conditions they’ve never experienced before. Whether it’s driving along 1,000-foot cliffs or dodging avalanches, skill and ingenuity go full-throttle.
