                        Charles Kahane, Chief, Evaluation Division, NPO-131, National Center for Statistics and Analysis, National Highway Traffic Safety Administration, Room 5208, 400 Seventh Street, SW., Washington, DC 20590.

# SUPPLEMENTARY INFORMATION:

Safety Standard 201 (49 CFR 571.201) was upgraded in 1995, with a 1998-2002 phase-in, to reduce occupants' risk of head injury from contact during crashes with a vehicle's upper interior, including its pillars, roof headers and side rails, and the upper roof (60 FR 43031). Initially, energy-absorbing materials alone were used to meet the standard; later, some vehicles were also equipped with head-protection air bags. NHTSA does not yet have enough crash data to evaluate the injury-reducing effectiveness of the energy-absorbing materials. However, the agency has conducted 154 matched pairs of impact tests with free-motion headforms in pre- and post-standard vehicles of 15 selected make-models. The Head Injury Criterion, HIC(d) averaged 909.9 in the 154 pre-standard tests and 667.5 in the post-standard vehicles. This is a statistically significant average improvement of 242.4 units of HIC. 

## How can I influence NHTSA's thinking on this subject? 

NHTSA welcomes public review of the technical report and invites reviewers to submit comments about the data and the statistical methods used in the analyses. NHTSA will submit to the Docket a response to the comments and, if appropriate, additional analyses that supplement or revise the technical report.
