Save Fuel and Breathe Easier!

School bus drivers in North Carolina are urged to minimize idling time to combat harmful diesel emissions, reduce fuel costs, and improve air quality. Diesel particulate matter (PM2.5 and PM10) poses significant health risks, especially to children, as it can aggravate respiratory problems and even lead to premature death. Recommendations include limiting idling to five minutes for air pressure and two minutes to cool down the turbo. Implementing these practices can ensure cleaner air and healthier students, with potential state-wide savings of $1 million annually.

  1. Save Fuel and Breathe Easier! It’s a Good Idea to Shut It Down: Reducing Unnecessary Idling School Bus Driver “Reduce Idling” Training North Carolina DMV June 2005

  2. Health Effects of Diesel Particles – Especially on Young Children • Due to tiny size of fine “Particulate Matter” it can penetrate deeply into the lungs • May cause allergy symptoms, including irritation to the airways • Aggravates bronchitis and pneumonia and triggers asthma attacks • PM is linked to cancer and increased heart attack risk; could lead to “premature death” • REDUCED IDLING REDUCES RISK!

  3. PM2.5 (2.5 µm) PM10 (10µm) Particulate Matter: What is It? A complex mixture of extremely small particles and liquid droplets Human Hair (70 µm diameter)

  4. Where Does PM Come From?

  5. The Decade of the Diesel • Public Policy reflects Health Studies • New, cleaner engine standards • New, cleaner burning fuels • Biodiesel • Ultra Low Sulfur Diesel (350 -> 15 ppm) • Diesel engine retrofits • “Idling Reduction” campaigns

  6. New Diesel Bus Engine Emissions Standards

  7. Rising Cost of Diesel Fuel • COST TRIPLED in 40 months • February, 2002: $0.55 per gallon • June, 2005: $1.66 per gallon

  8. School Buses in North Carolina • Outstanding safety record • In NC, more than 13,000 buses transport more than 700,000 students nearly a million miles a day

  9. School BusIdling Reduction Benefits • Cleaner, clearer air to breathe • Improved health • Cost savings • Reduced Idling Could Save $1 million per year statewide

  10. Reduced Idling Recommendations • Don’t idle your school bus longer than five (5) minutes to build up air pressure. Additional idling does not warm up the school bus. • Don’t idle your school bus longer than two (2) minutes to cool down the turbo at the end of the route.

  11. Reduced Idling Recommendations • Do not idle your bus while loading or unloading on school grounds.

  12. Reduced Idling Recommendations • Bus should NEVER be left idling and unattended!

  13. Diagonal Parking Nose to Tail Parking School Bus Parking Park Away from Air-Intake for School Buildings

  14. Be aware of your driving position Avoid following trucks or other buses if possible; if not possible, keep your distance to avoid THEIR exhaust School Bus Driving

  15. School Buses – Both Yellow & Green YOU Hold the Key ! Drive Clean
