Drivers Lisa Kelly, Alex Debogorski, Art Burke and Darrel Ward all attempt to conquer a remote, unmonitored trail, as the battle for Ice Road supremacy presses on. From lake crossings on thinning ice to wrong turns in the wilderness, the crew from Polar is put to the test. Meanwhile, rival VP Express' run over the melting roads leads to trouble when boss Hugh Rowland crashes into the ditch. Plus, Hugh shakes up the winter roads war when he makes Lisa an offer she might not be able to refuse.
At the top of the world, in the coldest parts of North America, there is a whole trucking industry that most people had never heard of. Some communities and industries can only be reached for a few months each year, when rivers or seas freeze over. Ice Road Truckers features the activities of drivers who operate trucks on seasonal routes crossing frozen lakes and rivers in remote arctic territories in Canada and Alaska.
Seasons 1 and 2 are based in Canada's Northwest Territories, first the diamond mines around Yellowknife and then the Mackenzie River ice road from Inuvik. Seasons 3 and 4 move to the USA and focus on Alaska's improved but still remote Dalton Highway, supplying the oilfields in Prudhoe Bay. Seasons 5 and 6 split coverage between Alaska and the winter roads Winnipeg, in Canada's Manitoba, while Alex heads farther north than ever before on the deadly Dempster.
