Frankfort. KY – A recent study finds that poor road conditions contribute to over fifty percent of car crash deaths in the U.S. each year. The Pacific Institute for Research and Evaluation rates Kentucky in the top ten states for crash costs at just under five billion dollars. Institute officials suggest improving poor road conditions could reduce crashes. However, financing is a problem. Last fiscal year state Road Fund revenues were over thirty-five million dollars below estimates. Next Fiscal year officials predict an over two-hundred and thirty million dollar shortfall.
