Tested vehicle: 2009 Chevrolet Silverado 1500 LT Crew Cab 4x2 without optional side airbags
Rating applies to 2007-09 models
The Chevrolet Silverado 1500 and GMC Sierra 1500 were redesigned for the 2007 model year. Two tests of a 2009 Silverado 1500 were conducted, one with optional side airbags for the driver and rear passenger, and one without. These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests.

| Driver head protection The dummy's head was hit by the window sill of the driver door. This impact did not produce high head injury measures, but the head protection is inadequate. |

| Torso | |
| Pelvis/leg | |
| Rear passenger head protection Although the intruding barrier did not hit the dummy's head in this test, the head was not protected from contacts outside the vehicle. This indicates that only slightly different crash circumstances could produce a direct hit to a person's head. |
