Three vehicle-pedestrian accidents in less than 24 hours kept rescuers in three counties busy.

The most serious was Tuesday just before 12:30 p.m. in Park City. A woman crossing state Route 224, the main road that leads into the city off I-80 and eventually turns into Park Avenue, was hit by a Park City transit bus. The bus driver was turning left from the Holiday Ranch Loop onto the highway when he hit the woman.

The woman's condition was unknown Wednesday. The bus driver was given a standard drug and alcohol test as part of an investigation and placed on administrative leave pending the outcome.

At about 7 a.m. Wednesday in Centerville, a 15-year-old boy was hit by an SUV while crossing Main Street. The teen suffered at least a broken leg, according to police.

The boy, a sophomore at Viewmont High School, apparently was trying to chase down the school bus by crossing the road. The bus driver yelled at the boy not to cross, according to witnesses. The bus had stopped, but it was not at a regular bus stop, police said.

Police say the road was still icy when the accident happened. The driver of the SUV attempted to stop when he saw the boy but could not, according to police. The impact of the collision threw the boy several feet.

Also Wednesday morning, not long after the Centerville accident, a woman in Salt Lake City was hit by a pickup truck with a snowplow on front. The truck was clearing snow from a parking lot when the driver inadvertently backed into a woman near 1700 S. Main.

The woman was taken to a local hospital with non-life-threatening injuries.
