Using a database of school bus drivers and public records searches, Randy Ludlow and Jill Riepenhoff of the Columbus Dispatch found that more than 150 school-bus drivers have records of drunken driving and drug abuse. “State laws, practice and policies make it virtually impossible for school officials to review complete driving histories maintained by the state,” they report. Despite the fact that Bureau of Motor Vehicles knows every offense committed by a licensed driver, not all of this information is shared. Abstracts obtained for background checks only include records from the past three years. Unbeknownst to most schools, full motor vehicle records can be obtained if requested specifically.
