U.S. light-vehicle sales dropped 1 percent in January, with higher fleet shipments offsetting lower retail volume, as the government shutdown and severe cold that blasted the Midwest this week dampened consumer demand.

Automotive News reports the seasonally adjusted, annualized rate of sales for January came in at 16.9 million, down from 17.22 million in January 2018 and December’s 17.72 million rate. It marked the first month the pace of sales has dropped below 17 million since August. Cars remain a weak spot across the industry, falling 4 percent last month, while light-truck deliveries rose just 0.3 percent.
