The LX 570 has not yet been crash-tested by either of the major programs, but it includes one of the longest lists of standard safety features in any vehicle.
Cars.com reports that the 2008 Lexus "boasts 10 airbags. In addition to the usual front and front-seat side-impact bags are second-row side-impact airbags and a knee airbag for each front occupant" along with head restraints--which are installed on the 2008 Lexus LX 570 for the first time.
Edmunds reports this Lexus 2008 model has "a comprehensive array of standard safety features, including stability control, antilock brakes with brake assist, front-seat side airbags and roll-sensing full-length side curtain airbags," adding that for 2008, "Lexus' pre-collision system is optional." Perhaps its best protection is its size; Popular Mechanics quips that if one "ever did hit anything with it at high speed, it would probably bounce off, since it's such a big, strong tank of an SUV."
As with many of the higher SUVs, rearward and sideway visibility can be an issue in the 2008 Lexus LX 570, especially on tight city streets. ConsumerGuide says that the Lexus 2008 LX 570's "high stance and rear-roof styling hamper visibility, but that's offset by large door mirrors, standard front and rear obstacle detection, and rearview camera."
