The school van collided head-on with a trailer.
The deceased, the driver of the school van belonging to Light Academy in Makueni County, died on the spot after the vehicle collided head-on with a trailer near the Sultan Hamud bridge on the Mombasa-Nairobi highway.
Six pupils and a teacher who were injured in the accident were rushed to hospital.
Peter Mudaki, a witness, said the van collided head-on with a trailer as the driver attempted to overtake a number of vehicles at high speed.
“Just before the bridge, the driver of the Nissan overtook a matatu. He then overtook a trailer and as he attempted to overtake the second trailer, he collided head on with an oncoming one," he said.
