Crash Testing Explained: What Happens in an IIHS Test?

Alright, let's get into the nitty-gritty of crash testing. It's not just about smashing cars into things (though that's definitely part of it!). The IIHS uses a range of tests to assess how well a vehicle protects its occupants in various crash scenarios. These tests simulate different types of crashes, like frontal, side, and rear impacts. The IIHS tests are designed to replicate real-world crash conditions as closely as possible, providing a realistic assessment of vehicle safety performance. The tests evaluate how well the vehicle structure protects occupants, the effectiveness of safety features like airbags and seatbelts, and the likelihood of injury. The IIHS uses advanced equipment and techniques to measure the forces exerted on crash test dummies during a crash. This data helps them determine how well a vehicle protects its occupants from injury. The IIHS's crash test program is constantly evolving to keep pace with changes in vehicle design and technology. The IIHS tests are incredibly detailed, and the results are used to assign safety ratings to each vehicle. These ratings are a valuable resource for consumers looking to purchase a safe vehicle. The IIHS tests include:

  • Frontal Crash Tests: These tests evaluate how well a vehicle protects its occupants in a head-on collision. The IIHS conducts two different frontal crash tests: the moderate overlap front test and the small overlap front test. The moderate overlap front test simulates a head-on collision between two vehicles, while the small overlap front test simulates a collision with a fixed object, like a tree or utility pole. These tests assess the structural integrity of the vehicle and the performance of safety features like airbags and seatbelts. The small overlap test is particularly challenging, as it focuses on the area of the vehicle where the impact occurs, often leading to more severe injuries.
  • Side Impact Tests: These tests assess how well a vehicle protects its occupants in a side impact collision. The IIHS side impact test involves a moving barrier impacting the side of the vehicle at a speed of 31 mph. The test measures the vehicle's ability to absorb energy and protect occupants from injury. This test has been updated to include a heavier barrier and a higher impact speed to better reflect real-world crash scenarios. These tests evaluate the structural integrity of the vehicle and the effectiveness of safety features like side airbags.
  • Rear Impact Tests: These tests evaluate the performance of head restraints in rear-end collisions. The IIHS uses a sled test to simulate a rear-end collision and measures the amount of force exerted on the test dummies' necks. This test is designed to assess the risk of whiplash and other neck injuries in rear-end crashes.
  • Roof Strength Tests: These tests evaluate the structural integrity of a vehicle's roof in a rollover crash. The IIHS applies a force to the vehicle's roof and measures how much weight the roof can withstand before collapsing. This test is designed to assess the risk of serious injury or death in a rollover crash.

The Role of Crash Test Dummies

Crash test dummies are the unsung heroes of vehicle safety. They're designed to mimic the human body and are packed with sensors that measure the forces of a crash. The data collected from these dummies helps the IIHS assess how well a vehicle protects its occupants. These dummies are sophisticated pieces of technology, representing different ages, sizes, and genders. They are equipped with numerous sensors to measure the impact of a crash on different parts of the body, such as the head, chest, and legs. The data collected from these sensors is critical in determining a vehicle's safety rating. The IIHS uses a variety of crash test dummies to ensure that its testing reflects the diverse range of people who drive and ride in vehicles. The dummies are calibrated to represent different body types and sizes, as well as different seating positions. This allows the IIHS to assess how well a vehicle protects occupants of all shapes and sizes. The dummies are also used to assess the effectiveness of safety features like airbags and seatbelts. By measuring the forces exerted on the dummies during a crash, the IIHS can evaluate how well these features protect occupants from injury. The data collected from crash test dummies is used to improve vehicle design and safety features. The IIHS shares this data with automakers to help them make their vehicles safer. This collaborative approach has led to significant advancements in vehicle safety over the years.
