Diesel Exhaust

"Not three minute idling. Not one minute idling. Zero idling! That's the only solution."

- Dr. Geoffrey Gordon, Superintendent (retired), Port Washington Public Schools


Most school bus drivers and monitors don't think of themselves as being responsible for the health of the children they carry. But they are.


There is no safe level of exposure to diesel exhaust. It is a known cause of both asthma and lung cancer, and has been linked to an increased risk of breast cancer. It can cause headaches, dizziness and nausea, and exacerbate respiratory diseases through inflammation and irritation of the airways.

Idling school buses and other vehicles on school grounds create an unnecessary risk for students, teachers and staff. Some states have time limits on idling, but compliance is inconsistent and enforcement is extremely difficult.

We strongly recommend policies that prohibit all idling of vehicles on school property. Please see our sample policy and sample signs for your program.
