Bus stop for call of nature

During Easter vacation I travelled to my home village by bus. In the course of our journey, the driver stopped the bus near a bush to allow passengers to attend a short call of nature. Is this common behaviour not regulated by the law?

It is contrary to regulation 10(2)(f) of the Land Transport Regulatory Authority (Certification of Commercial Vehicle Drivers and Registration of Crew) Regulations, 2020 as amended by Government Notice No.81 of 2021 for public passengers vehicle driver to stop at the bush where there are no toilets or other social amenities for the purpose of allowing passengers to attend a short call of nature. A driver who commits such an offence is liable to pay a fine of TZS 50,000 prescribed under the Fifth Schedule to the Regulations.
