Hello please do something…

Hello please do something about these diesel trucks smoking and emiting pure pollution into our air. I drive alot an all over I am petrified to breath in that disgusting black sut being stuck behind a city bus or school bus is nauseating never-ending the kids or people riding the bus. Or the people at the bus stops when a bus is accelerating pouring black smoke right into our faces. Something needs to be done. I know you'll try your best thank you
