Wisconsin authorities say a bus with about 20 adult Special Olympics athletes crashed while returning from Nebraska, leaving two people with serious injuries.
Dodge County Sheriff Todd Nehls says the bus driver lost control Tuesday about 3:30 a.m. and crashed into a guardrail near Waupun, which is about 50 miles northeast of Madison.
The guardrail prevented the bus from plunging down an embankment and instead kept it on the road where it tipped over.
Nehls says the 42-year-old bus driver and one athlete were in serious condition. The other 20 passengers were treated at a hospital and released.
Sheriff's Capt. Molly Soblewski told reporters the athletes were golfers and softball players returning from Lincoln, Neb.
