The icy road conditions on Sunday night lead to more than a dozen accidents in the greater Bangor area.
State police said they responded to at least 15 accidents on the Interstate.
Penobscot Regional Dispatch said they were called to about 20 between Etna and Plymouth.
Officials say some vehicles drove off the road while others were fender benders.
