On the morning of December 12, 2017, a school bus operated by the Riverside Community School District backed into a ditch on a rural road outside Oakland, Iowa, after picking up its first passenger, a 16-year-old female student. While the driver tried to drive the bus out of the ditch, a fire began in the engine compartment and spread throughout the bus. The driver and passenger died in the fire. The National Transportation Safety Board (NTSB) investigation focused on school bus driver fitness for duty, school bus fire safety, and school bus emergency training. The NTSB made safety recommendations to the US Department of Transportation; the National Highway Traffic Safety Administration (NHTSA); 44 states (including Iowa), the District of Columbia, and the territory of Puerto Rico; the state of Iowa; the Riverside Community School District; three school transportation associations; and seven school bus manufacturers. The NTSB also reiterated one recommendation to NHTSA and reclassified a previously issued recommendation to the three school transportation associations.
