Indiana State Police are warning drivers that cold temperatures and other weather conditions are causing black ice, which in turn leads to crashes in the Region.

ISP says, “Extreme icy conditions persist on all roads due to the subzero temperatures; because of the cold temperatures we also have the formation of black ice. This ‘phenomenon’ occurs every year with the winter weather yet some motorists forget this fact and don’t change their driving behaviors.”

State Police say black ice is a dangerous condition because it is difficult to detect, forming quickly in extremely cold weather, like today, caused when moisture rapidly freezes into a thin, transparent layer of ice on the roadway.  ISP warns that bridges, overpasses, underpasses and ramps can be especially dangerous.

It says road salt treatment is less effective in subzero temperatures, leaving icy roads across Northwest Indiana until temperatures become more favorable for chemical melting agents and plows.

ISP says its Lowell District troopers are busy with crashes, slide-offs and spin-outs in Lake, Porter, LaPorte, Newton, Jasper, Pulaski and Starke Counties.  State Police insist that drivers slow down, with the majority of today’s service calls caused by drivers traveling too fast for road conditions.
