Three people died on Saturday and several others were injured when a Mombasa-bound bus rammed into the car they were travelling in.
The accident happened at the junction of the Emali-Loitoktok Road and the Nairobi-Mombasa highway.
The car was coming from the direction of Loitoktok Town in Kajiado County, according to Makueni County Police Commander Joseph Napeiyan.
"The bus made a mistake. It overtook another vehicle and rammed into the car that was waiting at the junction for the Nairobi-Mombasa highway to clear," said Mr Napeiyan.
The injured were rushed to Kilome Nursing Home in Emali Town.
