One trooper did sustain minor injuries when someone crashed into his cruiser while he was helping another accident victim, Tingey said. That wreck happened about 10:30 a.m. on I-15 at 5600 South. The trooper suffered cuts and scrapes on his face and later experienced neck pain but was treated and released from the hospital, Tingey said.

Another trooper was arriving at an accident scene about 7:45 p.m. when a car slid out of control and struck his cruiser, Tingey said. That happened on northbound I-15 at 11400 South, but neither party was hurt.

Tingey said most of the wrecks were due to motorists driving too fast for the conditions or having bald tires or "just stupidity." Utahns need to remember how to drive in winter conditions, he said, and he encouraged everyone to slow down and be extremely cautious in bad weather.

The Salt Lake County Sheriff's Office reported more than 30 accidents during the day Sunday, but none resulted in serious injury.

The Valley Emergency Communications Center, which serves much of Salt Lake County, reported only about 30 crashes on Sunday, not too many more than normal.

Tooele County dispatchers reported only a couple of minor accidents. In Davis County, there were a half-dozen minor accidents after 4 p.m., dispatchers said.

Crashes continued to be reported throughout Salt Lake County on Sunday night. At 8 p.m., dispatchers reported that UHP troopers were "overloaded" in trying to respond to the various accidents, slide-offs and fender-benders on area freeways.
