On March 20, 2003 in Alachua County, Florida, a Carpenter school bus rolled over onto its roof. At the time of the accident, no passengers were on board and the driver survived the accident. In the rollover of the bus, the internal roof structure failed, causing much of the roof to collapse down to the level of the seats. Following the 2003 rollover accident, subsequent inspections of Carpenter school buses by operators in various parts of the United States revealed cracked and broken welds in their roof structures; the problem was not unique to the vehicle involved in the rollover crash.
