[Federal Register: May 11, 2009 (Volume 74, Number 89)] [Notices] [Page 21850-21851] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr11my09-597] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION National Highway Traffic Safety Administration [Docket No. NHTSA-2009-0095] Technical Report on the Effectiveness of Amber Rear Turn Signals for Reducing Rear Impacts AGENCY: National Highway Traffic Safety Administration (NHTSA), Department of Transportation. ACTION: Request for comments on technical report. ----------------------------------------------------------------------- SUMMARY: This purpose of this report is to determine the effect of rear turn signal color on the likelihood of being involved in a rear-end crash. Federal Motor Vehicle Safety Standard No. 108 allows rear turn signals to be either red or amber in color. The primary conclusion is that amber rear turn signals are 5.3% more effective than red rear turn signals at preventing involvement in crashes where a careful driver would typically use the turn signals. The result is shown to be statistically significant and consistent with other published analyses on the influence of rear turn signal color. DATES: Comments must be received no later than September 6, 2009 ADDRESSES: Report: The technical report is available on the Internet for viewing in PDF format at http://www-nrd.nhtsa.dot.gov/Pubs/811115.PDF.

SUPPLEMENTARY INFORMATION: Federal Motor Vehicle Safety Standard No. 108 allows rear turn signals to be either red or amber in color. Previous work on this subject includes laboratory experiments and analyses of crash data that suggest amber rear turn signals are beneficial. The present study was designed around the concept of ``switch pairs''--make-models of passenger vehicles were identified that had switched rear turn signal color, and crash involvement rates were computed before and after the switch. This method should control for extraneous factors related to vehicle and driver characteristics. Crash data from NHTSA's State Data System was used in the analysis. The principal finding of the report is that amber signals show a 5.3% effectiveness in reducing involvement in two-vehicle crashes where a lead vehicle is rear-struck in the act of turning left, turning right, merging into traffic, changing lanes, or entering/leaving a parking space. The advantage of amber rear turn signals is shown to be statistically significant. Procedural Matters How can I influence NHTSA's thinking on this subject?
