Nearly 8,000 diesel vehicles were tested for dark smoke emissions in a 12-month period, with 68 failures and fines issued totaling just under R30,000 (US$2,080), the City of Cape Town, according to a report by ENCA.
A mobile diesel emissions team tested 7,904 diesel vehicles over a 12-month period in the previous financial year – most of them heavy-duty trucks. Less than 1% of vehicles were found to be emitting dark smoke, according to the report.
Of the 68 failures, 40 were fleet vehicles where the owners had requested the tests. In these cases, repair notices were served instead of fines, as the testing was voluntary and did not take place on a public road, according to the report.
