It is also doubtful that driving slower really influences the level of fine dust on that particular day. As a matter of fact I suspect a secondary agenda in Belgium, from traffic safety lobbying, to prepare the people for stricter speed limits on highways independent from air pollution. Also it should be mentioned that in Belgium at least, most of the fine dust in traffic is caused by diesel engines, a choice of the public under influence of tax laws, making diesel fuel cheaper than gasoline. Fine dust from traffic is therefore in Belgium partially a government induced problem. As in Belgium, one should keep in mind that not traffic is the most important cause of fine dust.
