Three people died on the spot when a truck veered and knocked people along the road in Kijauri, Nyamira County on Sunday night.
Preliminary investigations indicate the lorry carrying avocados burst its tyre and ploughed into a crowd of people on the roadside.
Police said the canter was ferrying goods from Kisii county when its brakes failed before crashing into the crowd.
The bodies of the deceased were taken to Nyansiongo mortuary.
