The 2018 Sierra 2500HD’s available state-of-the-art safety and driver alert technologies provide peace of mind and help prepare you for the unexpected. Safety features are no substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. The 2018 GMC Sierra HD All Terrain Package lets you trailer and haul your payload wherever you need to, whether that takes you on a paved road – or off one. Front and rear body-colour bumpers, a more aggressive grille and distinct badging let you do it with style and presence.
