The late Minister for Transport, John Michuki, enacted the famous Michuki Rules to bring sanity on the road. Additionally, matatu drivers and conductors were required to wear badges and uniforms. PSVs had to have a visible yellow line painted on them.
But today, the relaxation of the regulation has given room such that matatus are allowed to have decorations and other messages. The beautiful messages and artistic drawings are sometimes good, but some are becoming a nightmare to Mombasa residents.
