Perrine said troopers have investigated more than 500 crashes in Indianapolis over the past five days, and in none of those cases were road conditions listed as the primary cause. “We’re tired of hearing the excuse that the roads are slick and hazardous,” Perrine said. “We don’t blame the road conditions for the crashes. People need to be prepared for those hazardous conditions.”He said roads may appear clear and dry, but icy and slick spots remain, creating dangerous driving conditions. In some cases, Perrine said, crashes can escalate into criminal investigations involving impaired driving.
