In general, the 2008 Chevrolet Impala gets strong, if not stellar marks for safety.
Crash tests conducted by the National Highway Traffic Safety Administration resulted in the Impala Chevrolet getting five stars for front-occupant safety in head-on and side impacts for models equipped with side airbags. Rear seat occupants fared slightly worse in this respect; the NHTSA awarded the Impala Chevrolet four out of five stars here.
The Insurance Institute for Highway Safety (IIHS) was less impressed with this Chevrolet 2008 model. In frontal offset crash testing, the Impala was given an "acceptable" rating, while side impact ratings were "good."
All 2008 Chevrolet Impala models come with dual front and side-impact airbags, as well as tire-pressure monitoring and OnStar emergency monitoring services. Every one of these Chevrolet 2008 vehicles also includes front seat belt pre-tensioners and latch child-safety seat attachments for the backseats. Car and Driver reports that "airbags [and] tire-pressure monitoring [are] standard across the lineup," but anti-lock brakes are not. All-disc anti-lock brakes and traction and stability control are standard on the higher trim levels, but cost extra on the entry-level LS and 1LT models.
