Keeping dustbins inside daladalas

My daladala crew were arrested by traffic police for not keeping dustbins inside the bus. He was ordered to pay a fine which he did but I still doubt if failure to keep a dustbin inside a commuter bus is an offence because I know for certain that all the commuter buses commonly known as daladala in Dar es Salaam don’t have dustbins. I would like to get your opinion on this issue if the traffic police was right.

Regulation 20(1) of the Land Transport Regulatory Authority (Certification of Commercial Vehicle Drivers and Registration of Crew) Regulations, 2020 [GN No.81 of 2020] imposes an obligation on the crew of commercial vehicles to ensure that dustbins are kept inside their buses and they are used by passengers. This rule was meant to keep our environment clean because in the absence of dustbins inside the buses, passengers do throw garbage and pollute the environment. Commuter buses are commercial vehicles so the crew of such vehicles are bound by the law to keep dustbins inside their buses. Failure to keep dustbins inside a commuter bus or any other commercial vehicle is an offence attracting a fine of not less than TZS 50,000 and not exceeding TZS 100,000 or imprisonment for a term of not less than 1 month but exceeding 1 year or to both prison term and fine. Owners of the commercial vehicles need to remind their crew to keep the dustbins inside the bus and ensure that the passengers are reminded to use the dustbins.
