I have seen some commercials on television about the importance of wearing seat belts. The research for these infomercials always seems to be done on crash dummies. How do they know the results are the same for humans?

Researchers have spent many hours recording and measuring the effects of car crashes on cadavers, crash dummies, and human volunteers. Experts have compared the results to see if they are the same.

When it comes to studying whiplash injuries, there are some concerns that crash dummies and cadavers have stiffer necks than humans. This may affect the accuracy of test results. For this reason, a computer simulation program has been planned. The results of this program match findings from human volunteers.
 
Thanks to advanced technology, researchers can look at the effect of changing car speeds on the force of impact. They can also change head positions at these different speeds. This provides accurate information without injury to anyone.
