A driver’s failure to maintain
control of a school bus – for reasons that could not be determined – and the
failure of the Riverside Community School District to provide adequate
oversight by allowing a driver with a known physical impairment to operate a
school bus led to the fatal Dec. 12, 2017, crash and fire in Oakland, Iowa,
said the National Transportation Safety Board during a public meeting the
agency held Tuesday.
The crash occurred when a school bus
driver turned from a rural gravel road onto a residential driveway for student
pickup. After the student boarded the bus, the driver reversed out of the
driveway and backed across the road, continuing until the bus’s rear wheels
came to rest in a 3-foot-deep ditch. While the driver attempted to drive the
bus out of the ditch, a fire began in the engine compartment and spread
throughout the school bus. The driver and the only passenger – a 16-year-old
student – died when they did not exit from the burning bus.

In the report released
Tuesday, the NTSB noted the origin of the fire was the exterior of the engine’s
turbocharger. Investigators found that when the bus came to rest in the ditch,
the exhaust was blocked. As the driver attempted to drive the bus out of the
ditch, repeatedly accelerating the engine, it caused turbocharger overload with
significant heat output which resulted in the fire.
tragic as this accident is, it’s important for parents and students to
understand that crash data shows students are safer riding in a school bus than
being driven to school in the family car, and, students are far safer on the
school bus than in a car driven by a teenager,” said NTSB Chairman Robert
to the severity of the fire was a gap in the firewall that facilitated the
spread of heat, toxic gases and fire into the passenger compartment. The NTSB
found small penetrations through the firewall were not blocked with
fire-resistant material and did not provide any fire protection or containment.
