Roadway Safety Groups Provide Funding for Safe Youth Mobility in Underserved Areas

GHSA has awarded a total of $125,000 from the National Road Safety Foundation to five states to partner with community-based groups to implement safe youth mobility programs focusing on walking, biking and/or riding a scooter.
