National Transportation Safety Board Safety Recommendation, H-05-12 through -16

These safety recommendations, addressed to the Honorable Mary E. Peters, Administrator, Federal Highway Administration (FHWA), are concerned with Federal guidance on identifying and eliminating locations with wet weather accident problems. The National Transportation Safety Board makes the following recommendations to the FHWA: (H-05-12) Issue guidance to FHWA field offices describing the inadequate stopping sight distance that could occur when poor vertical geometries exist at locations with low coefficients of friction and speeds higher than the design speed and work with the States to inventory such locations; (H-05-13) Once the locations in recommendation H-05-12 have been identified, assist the States in developing and implementing a plan for repaving or other roadway improvements; (H-05-14) Issue guidance recommending the use of variable speed limit signs in wet weather at locations where the operating speed exceeds the design speed and the stopping distance exceeds the available sight distance; (H-05-15) Conduct research on commercial vehicle tire and wet pavement surface interaction to determine minimum frictional quality standards for commercial tires on wet pavement, and once completed (1) revise the tire requirements for commercial vehicles operating on wet pavement at highway speeds and (2) develop minimum acceptable pavement coefficients of friction and maximum permissible pavement rut depths as part of roadway maintenance requirements, as appropriate; and (H-05-16) Review State programs that identify and eliminate locations with a high risk of wet weather accidents and develop and issue a best practices guide on wet weather accident reduction.
