Every year, our vehicles become safer. Much of that progress can be traced to the science behind crash-test dummies and biomechanics. Over the last few decades, crash-test dummies have become more important in enhancing our safety and security when car accidents occur. 

The Role of Crash-Test Dummies

Crash-test dummies, or anthropomorphic test devices (ATDs), are lifelike mannequins designed to mimic human size, weight, and movement in crash simulations. They are equipped with sensors throughout their bodies, which allow ATDs to measure impact forces, acceleration, deceleration, and bending movements during collisions.

These dummies provide consistent, repeatable data that enhances vehicle design and occupant safety. These tools are fundamental in preventing car accidents and related injuries.

Common Vehicle Safety Features Improved by Crash Testing

Today, many safety features drivers take for granted exist because of crash-test research and biomechanics. Seatbelts, for example, have been refined to distribute crash forces across the body’s strongest parts, reducing the likelihood of chest and abdominal injuries. 

Airbags have evolved to deploy at just the right speed and pressure to cushion the head and torso while minimizing the risk of secondary harm.

Crash testing has also led to stronger roof structures that prevent collapse in rollover crashes, improved child restraint systems, and headrests designed to reduce whiplash injuries. 

Even the placement of bumpers, crumple zones, and steering columns is influenced by data gathered from decades of crash testing. These everyday features directly result from ongoing research to make cars safer for everyone.

Biomechanics and Crash Tests

Biomechanics plays a crucial role in interpreting the data from these dummies. It helps researchers understand how specific forces during a crash translate into real injuries, such as brain trauma, chest compression, or spinal cord damage

This data guides engineers in creating crumple zones that absorb impact and strengthening vehicle frames to protect occupants effectively. It also helps them optimize the placement and deployment of seatbelts and airbags. 

The Evolution of Dummy Design

Over the decades, dummy technology has become increasingly sophisticated. Early models represented average adult males, but modern versions now include variations that better reflect different body types.

Today, the National Highway Traffic Safety Administration maintains a family of standardized crash-test dummies, including: 

  • 50th percentile adult male
  • 50th percentile adult male (hybrid)
  • 5th percentile adult female
  • Small adult female
  • 10-year-old child
  • Six-year-old child
  • Six-year-old weighted child
  • Three-year-old child
  • 12-month-old infant
  • Newborn infant

Each of these dummies varies in height, weight, and proportions. The largest stands at 5’9” and weighs about 171 pounds, while the newborn model weighs only 7.6 pounds. Researchers place them in different seating positions and pair them with various safety devices, such as seatbelts, booster seats, and airbags. 

This allows engineers to evaluate how effectively a vehicle protects a wide range of occupants—from the smallest infants to average adults—in real-world crash conditions.

How Long Does Crash Testing Take to Influence Vehicle Design?

The improvements drivers see on the road don’t happen overnight. Vehicle design changes can take years to complete. Once researchers collect crash-test data, engineers analyze the information, run computer simulations, and build prototypes for further testing. 

Automakers then conduct additional crash tests to verify the effectiveness of those changes before introducing them into their vehicles. In practice, crash tests can take time to translate into safety upgrades.

Crash-Test Dummies and Personal Injury Cases

When a crash causes injury, biomechanical data helps determine how a vehicle’s design, safety features, or failures contributed to the outcome. 

This data can illuminate whether a car behaved as expected or if design flaws played a role. If the latter is true, it may support a product defect claim against a car or part manufacturer.

Crash-test dummies and biomechanics have revolutionized vehicle safety, shaping everything from airbags and seatbelts to child restraints and crumple zones. By translating real-world crash forces into measurable data, they guide engineers in designing cars that better protect drivers and passengers alike. 

This same data is also invaluable in personal injury cases, where it can highlight design flaws or product defects that contributed to a victim’s injuries.
