What characteristics of a crash identify speed as related to an improper response to the driving environment? For example, crash data may identify high-accident locations with relatively frequent run-off-road crashes where drivers were at or under the speed limit, giving the impression that speed was not a factor.

For example, analysis of age and gender can help identify a target audience for public information and education campaigns. Review of other contributing factors can indicate a benefit to combining programs; such as a seat belt safety education program that includes information on speed reduction.

, "air bags combined with lap/shoulder seatbelts, offer the most effective safety protection available today for passenger vehicle occupant." Yet, also according to NHTSA, in 2006, of drivers age 21 and older involved in fatal crashes, those who were not speeding were more likely to be wearing seatbelts than those who were speeding at the time of the crash. For drivers age 21 and older, the percentage of speeding drivers involved in fatal crashes who were using restraints at the time of the crash was 43 percent, but 73 percent of non-speeding drivers in fatal crashes were restrained.

Roadway Characteristics Roadway elements can contribute to the speeds at which drivers feel comfortable as well as present drivers with situations they may not expect. Relevance of Road Design and Type Speeding-related fatalities were found to occur primarily on two-way, undivided roadways with 77 percent of speeding-related fatalities on low-speed roads and 62 percent of speeding-related fatalities on high-speed roads occurring on this roadway type in 2006.
