Colombo (LNW): People can now report vehicles that release too much black smoke to the Vehicular Emission Test Trust Fund. Public complaints can be lodged via a message with a clear photo of the polluting vehicle and its location to WhatsApp at 070 350 0525. Anyone using a vehicle that emits too much black smoke will be given a period of one month to fix the problem, or otherwise, their vehicle’s licence may be blacklisted, the Fund said. It added that complaints can also be lodged in any event in which the services of the emission and testing centres fail to perform their duties properly, by sending a WhatsApp message to the same number, or calling 011 266 9915. The Fund has found that nearly 30 per cent of vehicles in Sri Lanka release harmful black smoke. This smoke can cause diseases like cancer and breathing problems, according to health experts.
