The lorry which was right in front of the bus is said to have had a tyre burst. The driver tried to steer it out of the road, but the bus driver could not manage to slow down.
The MSL bus rammed the lorry from behind.
A 14 seater matatu and two other personal cars were also involved in the horrid accident.
The accident has caused heavy traffic jam along the busy highway that has been closed temporarily.
