Off road challenges are a recurring type of episode of Top Gear US in which the presenters go off roading in different types of vehicles. The first off road challenge was the ninth episode of the first season of Top Gear US, titled America's Toughest Trucks in which the presenters went off roading in Alaska using second hand trucks. So far, there has been one off roading challenge/episode per part of season (i.e. there are two total in season 2; one aired in part 1 and one aired in part 2).
