Twenty eight businessmen have filed a suit seeking the reversal of the government order for all school buses to be painted yellow.
Cabinet Secretary Fred Matiang’i issued the directive earlier this year while he was in charge of the Education ministry.
The order was effected after an amendment to the Traffic Act. Schools were asked to install safety belts and operate the vehicles only between 5am and 10pm.
The businessmen, who filed their case on Thursday, said compliance with the directives will shorten their working hours and reduce their earnings.
They also noted that failure to comply will put them at risk of arrest and prosecution.
