The federal government is considering a way to force states to lower the blood/alcohol levels at which a driver is considered drunk. The push to point-oh-eight is not winning the support of Iowa Congressman Tom Latham.Iowa’s legal limit is now point-one. States that fail to drop their levels to point-oh-eight could lose millions of dollars in federal highway money. Latham says that’s extortion.Only 18 states have the point-oh-eight drunk driving standard. A bill to establish point-oh-eight in Iowa cleared a state Senate committee last spring but the full Senate never acted on it.
