There are 28,198 diesel vehicles registered in Tainan County, of which 25,007 are registered as private vehicles and 3,191 as business vehicles. Also of the 28,198, 9,004 are registered as large passenger and cargo vehicles, and 19,194 are registered as small ones.
The emission control policy for diesel vehicles has been enforced for years, and the number of diesel vehicles that give up dark smoke is certainly reduced despite the vast size of Tainan County. However, in a time like this when economy is hanging low and incomes are shrinking, many car owners are reluctant to spend money on giving their vehicles a proper maintenance. When they are called upon for inspection, they usually tune down the throttle or rpm to steer their way through the inspection.
This year, the failure rate is approximately 8.3% for inspections carried out in stations. Visual identification on emission is basically carried out on old cars. The failure rate is approximately 5.1% for vehicles called upon for inspections in Tainan County.
For roadside inspection implemented this year, the emission of vehicles is screened by pulling over cars on the road and asking the drivers to push hard on accelerator. Inspection notices are given when there is a concern of pollution, and failure to meet pollution criteria is given a ticket on site. This helps deter some of the owners who tune down their cars before going to inspection stations, thus maximizing the effectiveness of inspection with limited number of inspections. In total, the number of vehicles that fail the inspections is 222.
The failure rate has dropped for diesel fuel inspections, and the efforts will keep going for optimal effect of deterrence. Also, a solution must be found for prosecuting illegal fuel trucks in order to stop any possible illegal actions.
The inspection stations of Tainan County have been CNLA-certified ever since 2001 for better inspection quality and credibility. Also, the stations have qualified in the supervisory evaluation of Taiwan Accreditation Foundation (TAF) in October 2008, and the laboratory certification is still valid.
