The Department of Land Transport (DLT) is calling on operators of six-wheeled trucks and over to register their vehicles before City Hall implements its Low Emission Zone air pollution control programme next year.
Under the programme, medium- and large-sized trucks will be prohibited from entering nine districts in central Bangkok during a certain period of the day to better control hazardous particulate matter smaller than 2.5 microns (PM2.5), DLT director-general Jirut Wisanjit said on Wednesday.
Only trucks which have registered with the programme, change their engine oil and air filter regularly, as well as electric trucks and NGV-powered ones will be allowed to enter the Bangkok districts where traffic is usually heavy and PM2.5 dust levels high.
