The report describes the National Highway Traffic Safety Administration's initial evaluation of the effectiveness of production Center High Mounted Stop Lamps (CHMSL), which have been standard equipment on passenger cars since September 1985. It is based on a census of police reported accidents that occurred at the 50 National Accident Sampling System (NASS) areas between June 1 and September 5, 1986, a nationally representative data set. The involvement rate in rear impacts for model year 1986 cars (all CHMSL equipped) is compared to 1985 cars (mostly without the lamps). CHMSL reduced the likelihood of being struck in the rear while braking by a statistically significant 22 percent. The data also suggest that CHMSL may be especially useful in preventing chain collisions involving three of more vehicles. All effectiveness estimates have to be considered preliminary and may change in follow-up studies based on larger accident samples.
