The bus was racing from Garissa heading towards Nairobi carrying 50 passengers when it was involved in the accident.
Survivors told police on reaching the location of the accident the driver was trying to overtake an unknown motor vehicle which did not stop after the accident and as he was trying to get back to his lane to avoid a head-on collision, he rammed onto the near side of a trailer ferrying gypsum.
The trailer also from Garissa had stalled on the road due to a mechanical breakdown, police said.
As a result of the accident, seven people were confirmed dead while more than 40 were evacuated to various hospitals.
Police arrived at the scene and declared an investigation had been launched before clearing it.
The bodies were moved to the local hospital mortuaries, police said.
Another accident had earlier on claimed five lives in the Maragua area, Murang’a on Thursday afternoon, police said.

The truck is said to have first hit the salon car forcing it off the road.
Five people who were on board died on the spot, police said. They included the driver and four passengers.
Residents protested the accident and blamed speeding for the same. They lit bonfires and demanded speed bumps be erected at the scene.
