Synthesis of Information Related to Highway Practices. Topic 55-10. Implementation of the Federal Highway Administration (FHWA) Proven Safety Countermeasures

For decades, public safety has been a priority for state departments of transportation (DOTs) as they strive to reduce traffic crashes. To support these efforts, the FHWA Office of Safety developed a list of proven safety countermeasures that include brief descriptions, information sheets, and additional references. These measures have been field-tested and proven to reduce crashes. The initial effort consisted of nine measures that any state DOT could implement. Today, in 2023, there are 28 such measures available. The objective of this synthesis is to document state DOT practices regarding the implementation of FHWA proven safety countermeasures.
