CEDAR RAPIDS, Iowa (AP) — The Iowa State Patrol says that troopers responded to at least 170 reports of vehicle accidents since snowfalls between four and seven inches fell earlier this week. Cedar Rapids television station KCRG reports at least one of those crashes was fatal. Troopers also responded to more than 230 calls for roadside help as of Tuesday.

The state’s transportation department said 12 of its snow plows were involved in the wrecks. The accident that resulted in the most damage occurred in western Iowa, where a plow crashed with a semitrailer, causing nearly $158,000 in damages. Officials say there were no serious injuries.
