No official factor has been established to have caused the crash but some eyewitnesses claimed that the driver of the Ebonyi Transport Company bus suffered fatigue and dozed off on while riding on the highway.

Another account claimed that it may have been caused by a break failure.
But the officials of Abia State Emergency Service quickly arrived at the accident scene to rush the injured passengers to the FMC, while the bodies of the dead victims were also deposited at the FMC mortuary.
