A Mazhandu bus travelling to Lusaka from Kitwe was involved in a road accident around 12 hours between Kabwe and Kapiri.
On the scene sources said five people have died on the spot while the sixth victim died on the way to the hospital.
The accident happened at a place called near the Green Leaf.
Among the deceased are four female passengers and a male aged between 1 and 2 years.
One of the female deceased passengers had her bridal shower on Saturday.
And the Road Transport and Safety Agency says it is saddened by the fatalities in a road traffic accident along the Kabwe Kapiri Mposhi road involving a Mazhandu Family Services Bus.
RTSA’s preliminary accident investigations conducted revealed that the driver of the motor vehicle failed to negotiate a curve, due to excess speed.
According to one of the eye witness, the driver of the bus Kasheka Shadrick Kabange was over speeding and failed to negotiate the curve and lost control causing the bus to slip on the road.
The investigations also revealed that the driver of the bus was fully licensed.
The investigation further showed that the section of the road where the accident occurred is a curvy stretch with a speed limit of 80km/h and the road is clearly marked and that the road is smooth.
The investigations have also revealed that the road was wet as it was raining during the time the road accidents occurred.
“As the RTSA, we are saddened by the loss of lives through an accident and urge all motorist to exercise maximum patience on the roads and avoid over speeding. And following a spate of road traffic accidents by Mazhandu Family Bus Services in the recent past, the Agency will be summoning the operator to show cause why the Road Service License (RSL) should not be suspended,” says RTSA Spokesman Fred Mubanga.
