Safety Recommendation Details

Safety Recommendation H-17-019
Synopsis: Speeding—exceeding a speed limit or driving too fast for conditions—is one of the most common factors in motor vehicle crashes in the United States. In this safety study, the National Transportation Safety Board (NTSB) examines causes of and trends in speeding-related passenger vehicle crashes and countermeasures to prevent these crashes. From 2005 through 2014, crashes in which a law enforcement officer indicated a vehicle’s speed was a factor resulted in 112,580 fatalities, representing 31% of all traffic fatalities. Speeding or speed has been cited as a safety issue, or a causal or contributing factor in 49 major NTSB highway accident investigations since 1967. Although recent speeding-related NTSB investigations have primarily involved large trucks and buses, most speeding-related crashes involve speeding passenger vehicles. In 2014, passenger vehicles constituted 77% of speeding vehicles involved in fatal crashes, and 78% of all speeding-related fatalities involved a speeding passenger vehicle. This study leverages prior NTSB investigations, together with other research, to address the national safety issue of speeding among passenger vehicle drivers. In this study, the NTSB used a combination of quantitative and qualitative methods to summarize the risks of speeding, describe the scope of the problem, and promote the use of proven and emerging speeding countermeasures. This included a literature survey; analyses of speeding-related crash data; and interviews with national, state, and local traffic safety stakeholders. The stakeholders were representatives from transportation and highway safety agencies, law enforcement agencies, automobile manufacturers, research institutions, advocacy groups, equipment vendors, personal auto insurance providers, and professional associations. This study assessed speeding among passenger vehicle drivers in a broad sense, as a factor that contributes to crashes and injury severity. Several, of many, potential solutions to the issue of speeding-related crashes are discussed. The solutions do not address every cause of speeding or type of speeding-related crash, but they are intended to be widely applicable to a significant portion of these crashes.
Recommendation: TO THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION: Identify speeding-related performance measures to be used by local law enforcement agencies, including?but not limited to?the numbers and locations of speeding-related crashes of different injury severity levels, speeding citations, and warnings, and establish a consistent method for evaluating data-driven, high-visibility enforcement programs to reduce speeding. Disseminate the performance measures and evaluation method to local law enforcement agencies.

Safety Recommendation History
From: NTSB
Date: 3/8/2018
Response: We note that you plan to work with the law enforcement community to develop the recommended performance measures. We encourage you to share with us further details of your plan and a proposed timeline for completing these actions as they are developed. Pending such updates on your efforts, Safety Recommendation H-17-19 is classified OPEN--ACCEPTABLE RESPONSE.

Date: 12/11/2017
Response: -From Heidi R. King, Deputy Administrator: NHTSA recognizes that while speeding is a national problem, it is clear that solutions must be applied locally. The speeding-related fatality rate per vehicle mile traveled is highest on local and collector roads where the lowest speed limits are posted. Law enforcement agencies vary dramatically in size as do the communities they serve. Performance measures to be used by these agencies must therefore be appropriate and adaptable to fit wide-ranging community speeding issues. NHTSA will work with the law enforcement community to identify the best approach for establishing recommended speed management performance measures. NHTSA requests that Recommendation H-17-19 be classified as "Open – Acceptable Response."

From: NTSB
Date: 8/15/2017
Response: On August 15, 2017, the NTSB adopted its report Reducing Speeding-Related Crashes Involving Passenger Vehicles, Report Number SS-17-01. The details of this accident investigation and the resulting safety recommendations may be found in the attached report, which can also be accessed at Among the Safety Recommendations are eight issued to National Highway Traffic Safety, which can be found on pages 56 and 57 of the report. The NTSB is vitally interested in these recommendations because they are designed to prevent accidents and save lives. We would appreciate a response within 90 days, detailing the actions you have taken or intend to take to implement these recommendations. When replying, please refer to the safety recommendations by number.
