The Tahoe hasn't been tested by the Insurance Institute for Highway Safety, but in the federal government's new, more stringent crash tests for 2011, the Tahoe gets top five star scores in both frontal and side impact—with an overall score of four only because it's such a tall vehicle and thus more rollover-prone. The Tahoe also achieves a top five-star score in the new NHTSA side pole test, which isn't yet figured into the overall score.
Standard safety features include dual front, side, and curtain airbags that cover all rows of seats; traction and stability control; OnStar; and tire pressure monitors.
Outward visibility can be an issue in the Tahoe; with its very tall stance and wide pillars, parking and lane changes require some double checks—though wide side mirrors help with those lane changes. A rearview camera is an option, as are rear parking sensors and a blind-spot warning system.
