Request for Comments; CISS Expansion

Notice and request for comments.

On November 15, 2021, Congress passed the Bipartisan Infrastructure Law (BIL).

Users of CISS and other crash data may comment as to the future utility of current CISS, recommend ways to upgrade current CISS, and indicate their anticipated data needs.
