An accident involving a tour bus and two other vehicles on a Chicago highway sent 20 people to area hospitals with minor injuries.
The accident occurred on June 5 on the Dan Ryan Expressway. Police said two cars traveling in the northbound lanes crashed, after which one of them sped away. The other vehicle spun around, causing the tour bus to hit it before colliding into a three-foot-high median.
No one was killed in the incident. Published reports say 34 people refused medical treatment on the scene.
The accident happened less than a week after another tour bus crashed on a Virginia highway, killing four people and injuring more than 50 others. The driver was charged with involuntary manslaughter.
The Virginia crash has prompted some lawmakers to advocate for stricter time-off requirements for interstate bus drivers. Senator Sherrod Brown of Ohio and Senator Kay Bailey Hutchinson of Texas have co-written pending bus safety legislation that would require to take 10-hour breaks between shifts.
