The 2008 GMC Sierra 1500 earns superior marks from the National Highway Traffic Safety Administration (NHTSA). At the time of this writing, the Insurance Institute for Highway Safety (IIHS) has not tested the GMC 2008 Sierra 1500.
Car and Driver reports "four-wheel antilock brakes and an electronic stability system" as standard offerings on this GMC's 2008 model. ConsumerGuide reports additional standard safety equipment that includes "dual front airbags, antilock brakes, antiskid system w/rollover sensor (for the Crew Cab only), tire-pressure monitor, daytime running lights." It is a concern that "Side curtain airbags and adjustable pedals are optional on most models" of the GMC 2008 Sierra 1500, according to Edmunds.
ConsumerGuide says that the 2008 GMC Sierra 1500's "visibility is generally good, though the extended cab's thick rear pillars hinder view to back corners."
