摘要

In May 2005, the National Transportation Safety Board (NTSB) began its investigation of a school bus accident that occurred in Liberty, Missouri. During the course of the investigation, information was uncovered that suggested pedal misapplication as a factor in the accident-that is, depressing the accelerator instead of, or in addition to, the brake pedal.
