The Ice Road Truckers are back in action, and the roads are more dangerous than ever. Lisa's first run of the season goes south in a hurry. Two rookie drivers raise the stakes in the "Dash for the Cash." And old pros Hugh and Alex, along with wildcard Rick Yemm, leave Alaska behind to take on some of the most remote and deadliest roads on the planet.

Hugh and Rick roll deeper into the Canadian outback, while a dangerous overflow may leave Alex stranded in the wilderness. Dave's training run with Tony reaches the boiling point. Lisa Kelly goes on a rescue mission. And Maya's first look at the Haul Road may be enough to send this rookie back to the big city.

Hugh and Rick play with fire when a bent rim throws them off their schedule. Meanwhile, Maya takes the wheel for the first time and Dave sets out on a haul to Prudhoe under the watchful eyes of his Carlile bosses.

Ice road veterans are put to the test when sparks fly during a massive haul, leaving one trucker in a dangerous situation. Meanwhile, Lisa helps out a fellow trucker in need of roadside assistance. Will she keep up her reputation as a push-truck pro?

Rick and Hugh continue their marathon run, but the Winter Roads wreak havoc on the trucks leaving Hugh stuck on the side of the road.

The Canadian roads show no mercy for Hugh when a blow-out leaves him stuck on the side of the road. Meanwhile, Alex rescues a local family stranded in the wilderness and Lisa's dream job turns into a nightmare as she struggles to handle a massive load.

Halfway through the season, the biggest storm yet descends on the Dalton. Facing more than just a whiteout, the truckers must overcome a series of snags and find themselves in need of rescue. Meanwhile, Lisa faces the consequences of her last load ending in the ditch.

A whiteout paralyzes the Dalton as the truckers struggle to stay on the road. Meanwhile in Canada, Hugh and Rick end up lost when they take a dangerous haul into some of Ontario's most remote terrain.

Harsh winter weather has left Lisa stranded in Prudhoe Bay. Dave is in a convoy with Maya and Tony, he tests their patience before leaving them behind. In Canada, Rick's frustration reaches a boiling point and he snaps, while Hugh rescue's Rick's truck, again.

Hugh and Rick face an obstacle that has the ice road blocked, until Hugh decides to clear a path, while Alex gets too close for comfort with a parked car.

Hugh, Rick and Alex meet up at a fuel stop and decide to convoy north together. Back in Alaska, Lisa gets the break she's been waiting for when she convoys with Tony on the widest load yet, while things start to heat up for Maya.

Lisa and Tony honor a fallen trucker by spreading his ashes off of the Dalton, and Alex presses on despite feeling ill. Meanwhile, Hugh hauls a 30-ton load of boulders down the thawing surface of Lake Winnipeg while Rick is stuck waiting for repairs.

In Alaska, Lisa and Maya help a stranded driver get back on the road. Tony gets a surprise from Carlile while Dave continues his descent into isolation. In Canada, Hugh and Rick keep up their load count with backhauls. Alex has to deal with unstable freight but also scores a backhaul, keeping the race with his rival close.

With the end of the ice road fast approaching, the Ice Road Truckers are sprinting to the finish. But they've got obstacles. A polar bear standoff at Prudhoe Bay tables the plans for oil production and ties up Carlile's loads at the most crucial time of the season. A veteran trucker's calculated risk puts his life and livelihood in jeopardy. One rookie's sent packing as the other picks up the slack. And the Dalton's favorite daughter gets her groove back.

The season end is approaching and so is the load count in the Dash for the Cash. Hugh and Rick has trouble in Canada, will Alex take over the lead? Maya the Dalton-rookie convoys with Lisa to the remote and isolated Nuiqsut village. Tony deals with deteriorating road conditions and Dave leaves Alaska for Alabama.
