Sgt. Brian Peterson of UHP said speed is the number one cause of crashes on slick roads.
“Posted speeds are for dry/ideal conditions.  Slow down for wet, snowy, slushy, icy roads,” he said.
He recommends avoiding cruise control and hard braking, as well as increasing stopping distance when traveling in winter conditions.
