Design of a Dynamic Rollover Test
System," SAE Int.
Occupant kinematics during rollover motor vehicle collisions have been investigated over the past thirty years utilizing Anthropomorphic Test Devices (ATDs) in various test methodologies such as dolly rollover tests
, CRIS testing, spin-fixture testing, and ramp-induced rollovers.
The only dynamic rollover test
conducted on the F-150 four-door SuperCab the dolly rollover test
--was for defense purposes in Alaniz.
The National Highway Traffic Safety Administration (NHTSA) established the test program to evaluate whether the government should adopt a single rollover test

NHTSA's new dynamic rollover tests
will give consumers a valuable new tool for comparing vehicle safety and ultimately save lives," said CU Senior Vice President for Technical Policy, Dr.
It also added a rear-end fixed-barrier collision test and a static rollover test
for vehicles with a gross vehicle weight rating (GVWR) of 6,000 pounds or less.
NHTSA is developing a new rollover test
for SUVs, but says drivers should take responsibility for their own safety by wearing seatbelts, avoiding alcohol when driving and obeying speed limits.
For more than a decade, CU has urged NHTSA to develop an on-road rollover test
, which the agency is mandated to do by November 1, 2002.
The TREAD Act imposes various requirements for automobile, tire and automobile parts manufacturers, including a requirement for the National Highway Traffic Safety Administration (NHTSA) to develop a dynamic rollover test
Consumers Union, which has twice petitioned NHTSA to develop a dynamic rollover test
since 1988, believes the agency's rating system is inadequate because it isn't based on tests of a moving vehicle and can't account for what could be critical differences in emergency handling caused by suspension design, tires, steering response, or the presence of a stability-control system.
The OmniCity has already passed the rollover test
specified in European tourist coach regulations (ECE R66), which stipulate that deformation of the body caused by overturning must not invade a defined survival space.
