'Glider trucks' are pollution machines, but they might roll past EPA regulations
Old, inefficient engines inside new frames have been sneaking through a regulatory loophole that the EPA was supposed to be closing.

New freight truck frames can be fitted with old engines, which are cheaper and more polluting.
Leading up to the Trump administration, the Environmental Protection Agency had been on track to regulate a group of highly polluting freight trucks called gliders or glider kits.
Compared to conventional new trucks, glider trucks—rebuilt from old, salvaged diesel engines fitted into new frames—emit approximately 55 times more soot and other fine particle pollution associated with a higher risk of asthma, lung and heart disease, and premature death, according to the EPA’s own analysis.
