Five people died on the spot after a lorry collided head-on with a tractor in Transmara West, Narok County.
Transmara West Deputy County Commissioner Mohammed Hassan confirmed the Tuesday morning accident.
Among those killed are sugarcane cutters who were on the tractor.
The accident comes in the wake of a surge in tragic road crashes that has so far claimed close to 10 lives in less than 48 hours.
Last evening, a Murray Girls Form One student was killed in a tragic road accident in Tsavo on Monday evening.
The deceased was in the company of several other colleagues who were travelling back to school after the midterm break.
Confirming the accident, Taveta Police Commander Charles Baraza stated that the accident occurred when the matatu driver swerved sharply to avoid hitting an elephant.
Thereafter, the matatu lost control and rolled off the Taveta-Voi road before coming to a stop on the opposite side.
The police boss added that the Form One student died as she was being rushed to the Moi County Referral Hospital in Voi for treatment.
Nine other students who sustained minor injuries were treated in Voi and discharged while three other students sustained serious injuries and were rushed to the Coast General Hospital for specialized treatment.
It remains unclear why the matatu was packed beyond capacity, in apparent violation of Covid-19 protocols that require vehicles to carry no more than 60 percent of normal capacity.
A day earlier, two teenagers perished in a crash along the Southern bypass in Nairobi after the vehicle they were travelling in lost control and rammed into an electricity pole, killing them on the spot.
Three survivors were rushed to Nairobi hospital.
Reports which Kenya Leo could not independently verify surfaced indicating that the teenagers were drunk at the time of the accident.
