The Kenya National Highways Authority has issued a traffic advisory on the Rironi-Mai Mahiu Road.
The Authority said the Rironi-Mai Mahiu Road is experiencing a huge traffic jam.
The jam comes after a trailer veered off the road and crashed into the railings blocking traffic to and from Mai Mahiu.
KeNHA said motorists and other road users are advised to avoid the traffic jam by using alternative routes.
Kenyans have been advised to use the main Naivasha to Nairobi highway.
The Authority said the recovery process is underway to tow the cabin off the carriageway.
