Comedienne Sue Perkins and adventurer Charley Boorman travel to the Dalton Highway in Alaska – a dirt track built as a supply road to support the Trans-Alaska pipeline road in the 1970s. Highway maintenance is a full time job here with avalanche units operating throughout the year. The pair must make friends with the hardcore truckers for whom the highway is home.
The rules of the road are: drive with headlights on at all times, don’t exceed 50mph, and when an 18-wheel truck comes thundering down the rollercoaster towards you, get out of the way!
