Dear Sir,

Several Department of Transportation buses are spewing thick, black and putrid exhaust emissions as they travel along our roads.

The situation is disgustingly unhealthy, not only to road users, but also to the environment generally.

Perhaps, this matter will attract the attention of the powers that be, especially the head mechanic — “automotive technician” in today’s world — and corrective action will be taken before more buses are completely broken and consigned to the scrapheap.
