One way to reduce this source of air pollution is by testing diesel exhaust and requiring vehicle owners to repair their vehicles where needed. Periodic emissions testing of diesel vehicles will ensure that diesel owners share responsibility with gasoline vehicle owners for cleaning the air we all breathe. Small particles found in diesel smoke are considered to be health hazards, particularly for children and the elderly. Increased lung disease and asthma rates have been associated with diesel pollution. The U.S. Environmental Protection Agency has concluded that long-term exposure to diesel exhaust is likely to cause cancer in people.
All testing is done at licensed testing stations.
These are the same stations that currently perform the heavy-duty safety test. Become licensed fleet inspectors and conduct tests in their own garage. Contact an authorized inspection station that can send a mobile inspector to the vehicle owner's garage. Like gasoline powered vehicles, all diesel vehicles must be inspected for safety every year and for emissions every two years - before the current inspection sticker expires. Yes, this program requires all heavy-duty diesel vehicles, including buses and trucks, to pass an emissions test.
