Bangkok Bans Big Trucks Dec. 1 to Control Smog

Bangkok Heavy Trucks Smog Smoke Black PM2.5

Bangkok will ban large trucks from city streets during daytimes for three months starting Dec. 1 to mitigate season smog that already has begun.

Trucks with six or more wheels will be outlawed from 6 a.m. to 9 p.m. from Dec. 1 through Feb. 28.

The traffic measure is part of Bangkok’s plan to battle microscopic dust and air pollution, signs of which began Tuesday, said Bangkok governor Aswin Kwanmuang.

He said city hall was concerned over fine dust pollution from December to February as stagnant winds and high-pressure systems will trap particulate matter 2.5 microns and small close to the ground.

He convened a meeting with the Pollution Control Department, the Meteorological Department, the Land Transport Department, the Industrial Works Department and the Health Department to discuss the measures to cope with the pollution.

He said the BMA has already install the dust monitoring stations at all 50 district and tit will finish setting up the air quality measuring sensors at additional 20 parks in mid-November, so people will be able to monitor the air quality if it is safe to do exercise at the parks.

Past data has showed that last year’s truck ban helped cut fine dust in the capital by at least 39 percent.

Schools also will be asked to refrain from outdoor activities during the three-month period.

If the dust pollution reaches the crisis point for three consecutive days, schools can order closure, depending on the situation.

Construction activities will be put on hold if the ultra-fine dust level climbs to an unsafe level, he added.
