The 2010 Terrain scores very well in crash testing, receiving a full five stars from NHTSA for driver and passenger frontal crash tests and for front- and rear-seat side impact tests. Rollover testing hasn't yet been performed on the 2010 Terrain by NHTSA. The IIHS also rates the 2010 GMC Terrain well, giving it the highest score of "good" in frontal offset and side impact tests, and awarding it a Top Safety Pick designation.
Standard safety features include anti-lock disc brakes, stability control, and a full complement of airbags with dual-stage frontal and thorax side-impact, driver and front passenger, and protection for head curtain side-impact at both front and rear outboard seating positions.
Optional rear parking sensors round out the available safety gear, combining with the standard rearview camera to make it easier to see obstacles behind the vehicle. The display is mounted in the rearview mirror in non-navigation-equipped vehicles. All 2010 GMC Terrains come standard with a PASS-Key III Theft Deterrent System as well.
