Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.
Dummy movement was well controlled. During rebound, the dummy's head hit only the head restraint, as indicated by smeared greasepaint.
Forces on the lower left leg were high enough to indicate the possibility of injuries.

Tested vehicle: 2009 Chevrolet Silverado 1500 LT Crew Cab 4x2 without optional side airbags
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. |

| Rear passenger injury measures | |
| Head/neck | |
| 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. |

Action shot taken during the side impact crash test showing the driver dummy's head leaning well outward and approaching the window sill.
Intrusion of the B-pillar and door sill into the occupant compartment is apparent in this view.
