U.S.
DOT Proposes Tougher Standards To Protect
Occupants in Side-Impact Crashes
US
Secretary of Transportation Norman Y. Mineta proposed a major regulatory upgrade
in side-impact crash protection for all passenger vehicles.
The
proposed upgrade, developed by the DOT's National Highway Traffic Safety Administration
(NHTSA), would require auto manufacturers to provide head protection in side crashes
for the first time. It would also enhance thorax and pelvis protection for a wider
range of vehicle occupants involved in such crashes.
In
addition, the upgrade -- which would strengthen Federal Motor Vehicle Safety Standard
214 -- represents a significant advance in the use of crash test dummies. For
the first time, a dummy representing a small adult female would be used in side-impact
performance testing. A new and more technically advanced dummy representing an
adult male of average height would also be used in such crash testing.
"This
change in the way new vehicles are tested would take our safety program to a new
level and have a dramatic, positive effect on traffic-related fatalities,"
Secretary Mineta said.
NHTSA
estimates that the change would save 700 to 1000 lives per year. NHTSA also estimates
that, in serious side-impact crashes involving at least one fatality, nearly 60
percent of those killed have suffered brain injuries.
"We
expect that this rigorous requirement will spur the introduction of a comprehensive
array of technologies for side-impact protection. The proposal represents a major
step toward safer vehicles," said NHTSA Administrator Jeffrey W. Runge, M.D.
While
NHTSA does not require specific technologies to meet its performance standards,
manufacturers would likely meet this upgraded rule with various types of innovative
head, chest and pelvis protection systems, such as side air bags.
The
proposed regulatory upgrade could become a final rule as early as 2005, with a
phase-in for all new vehicles beginning four years after publication of a final
rule. This upgraded rule would augment the current side-impact standard by requiring
manufacturers to meet an additional performance test involving a 20-mph vehicle
side impact into a rigid pole at an approach angle of 75 degrees.
The
new pole test reflects real world side-impact collisions in which head injuries
are prevalent. A large number of deaths in such crashes occur when a single vehicle
strikes a tree or a utility pole. Other dangerous side-impact crashes often happen
when a large vehicle strikes a smaller one at an intersection.
"Our
goal is to protect all sizes of people, whether they are hit by an SUV or a pickup
truck, or run into a tree," Dr. Runge said.
The
new female crash test dummy called for in the proposed rule represents a 4-foot
11-inch woman. Use of this dummy -- along with the more technically advanced male
dummy -- will promote the development of head and thorax protection systems that
will provide improved side-impact safety for a wider segment of the population.
