Black Ice Suspected as the Primary Cause

Authorities suspect the accidents were caused by black ice, a thin, transparent layer of ice that forms when rain or snow freezes on the pavement. Because it's nearly invisible to drivers, it often leads to high-speed pileups before anyone can react. Traffic on the expressway remained restricted for several hours as emergency crews cleared the wreckage.
