Nearly a week after a charter bus crash involving a group of Hilliard Heritage Middle School students, parents and school district officials are still seeking answers to one very important question.

How did an unlicensed drunken driver end up behind the wheel of a vehicle transporting students on a field trip?

On Friday, May 21, the charter bus transporting students from Hilliard to Cedar Point on a field trip ran off the road and crashed in Huron County. No students were seriously injured, but a chaperone was transported to the hospital and was treated and released that day.

Superintendent Dale McVey said in a statement on the district's website that later that day that he was notified by the Ohio State Highway Patrol that the bus driver was intoxicated and did not have a required commercial driver's license.

The driver, Ronald L. Williams, 46, was arrested following the accident. Williams pleaded not guilty to charges of child endangering, drunken driving, failure to control and operating a commercial vehicle without a commercial driver's license.

According to the State Highway Patrol, Williams' blood-alcohol content was 0.103 percent, above the legal limit of 0.08 percent.

"Our first concern, as always, was the safety of our students," McVey said in a statement. "We immediately contacted the charter bus company, Urban Express Transportation, and they assured us that the remaining drivers on the trip were all properly licensed, fully-qualified professional drivers. To further ensure our students' safety, the district also checked for up-to-date insurance on the buses and had the Cedar Point Police check each of the remaining drivers for any signs of impairment. We are pleased to report that all the students were returned safely to Hilliard Heritage Middle School."

McVey said the district is reviewing its policies and procedures for renting charter buses.

"The district is greatly distressed about this accident and the condition of the driver," he said. "As we moved forward today, we took steps to form a committee to review our policies, practices and procedures surrounding the rental of charter buses for trips involving Hilliard City Schools students. Through this process, we will determine if any alterations need to be made to our field trip protocol.

"We are extremely concerned about this situation and are taking every measure to ensure our students' safety on future field trips."

Hilliard City Schools spokes-person Carrie Bartunek said Tuesday afternoon that the district is reviewing all remaining field trips for the current school year to see if any changes need to be made. Included in that review will be taking a closer look at companies the district contracts with for charter bus services.
