Side Impact Crash Test Results
In side crash tests, the National Highway Transportation and Safety Administration uses crash-test dummies to represent an average-sized adult. These “model” drivers are placed in the driver and rear passenger seats, then are secured with the original automobile manufacturer’s seat belts. Side crash tests are modeled after an intersection-type collision with an average 3,000 pound guard barrier composed of material that has a “give” to replicate the front end of another automobile.
All tested autos are impacted by the same size guard barrier, so it is important to remember this when looking at the side crash protection ratings of your new or used car.
High tech measuring instruments are now in place to measure the impact force to each dummy’s head, neck, chest, and pelvis. A Star Rating is then given based off the automobile’s performance. These rating indicate the chance of a serious chest injury for the driver and front seat passenger, as well as the rear seat passengers. Measured, though not considered, is the injury sustained by the head, through the “Star” rating system. There is a separate rating system specifically for head trauma. Similar to frontal crash ratings, a serious injury is one requiring immediate care by a medical professional, and may be life threatening.
- 5 Star = 5% or less chance of serious injury
- 4 Star = 6% to 10% chance of serious injury
- 3 Star = 11% to 20% chance of serious injury
- 2 Star = 21% to 25% chance of serious injury
- 1 Star = 26% or greater chance of serious injury
