What is Vehicle Idling? Vehicle Idling is when cars, trucks, buses, and other vehicles remain on and running while not moving. In this toolkit, you will help reduce exposure to harmful vehicle exhaust at your school by creating a No Idle Zone. Launch this No Idle Campaign to encourage parents, teachers, and other drivers to limit idling time for vehicles.

Toolkit Details


This toolkit address the following Science and Engineering Practices (SEPs) within the Performance Expectations of NGSS for Grades: K-2 and 3-5

  • Asking Questions and Defining a Problem
  • Planning and Carrying out Investigations
  • Analyzing and Interpreting Data
  • Using Mathematics and Computational Thinking
  • Constructing Explanations and Designing Solutions
  • Obtaining Evaluating, and Communicating Information

Why is it Important?

Idling cars release harmful toxins, add to the global crisis of air pollution, and increase the risk of asthma in addition to other health effects in the developing lungs of children through the use of gasoline.

What You Will Accomplish

Students will run a public service campaign to reduce vehicle idling resulting in cleaner air around your school campus.

Teacher Project Plan Step-by-Step

Step 1: Who’s participating?

  • Working with a small group of students? The group will observe the most trafficked pick up zone at school
  • Working with a larger group? Split up into teams and have each observe the pick up zone on different days of the week OR each team can choose to observe a separate pick up zone

Step 2: Set Learning Objectives


  • Students will collect and analyze data from “pick up points” to gain metrics for before and after the campaign
    • Examples:   
      • Pre-campaign observations of total # of vehicles, # of vehicles idling, total idling minutes, average idling time. (Worksheet provided in lesson plan section)
      • Split observation areas into zones and discuss why certain zones might have more idling cars (e.g., all vehicles on one side of the street in one block; all vehicles on both sides of the street on a small block; all vehicles in the school’s traffic circle; all vehicles in one section of the school’s parking lot, etc.)
      • Analyze data based on the size of the car and calculate how much gasoline is used with provided formulas.

Project Management

  • Students will learn to run a public service campaign to its entirety
  • Students will practice commitment to collection, analysis, and presentation of data
  • Students will coordinate letters and pledges
  • Students will practice leadership skills by delegating tasks to others

Evaluation and Assessment

  • Students will track and evaluate the impact of their project
    • Examples
      • Tally the weekly reduction of cars idling week-over-week
      • Report the impact of their work to the school/city/community

Step 3: Educate Students on the Environmental Impact of Idling Vehicles

The resources provided can be shown as a slideshow or printed out as individual worksheets for students to learn.

Education Materials: Why Should You Start a No Idle Zone?

Human activities cause air pollution

Every day human activities such as driving and manufacturing add greenhouse gasses and particulates to our air. These gasses and particulates cause air pollution which can be bad for the environment and our health. Additionally, these harmful gasses absorb heat from the sun and add to the already increasing temperature of the earth’s atmosphere.

Transportation creates pollution

The EPA has identified 188 Hazardous Air Pollutants also known as Air Toxics. Many of these come from cars and trucks that are on our roads every day. Pollution emitted from cars and trucks are called Mobile Source Air Toxics and are the largest contributors to air pollution in the US. [1]

Pollution affects everyone, but kids especially!

Toxins from cars and trucks have proven to cause serious health effects such as asthma and cancer. Children are even more at risk when surrounded by these toxins because their lungs are still developing. It is proven that when children are exposed to high levels of toxic air they are more likely to develop asthma, respiratory problems and other health complications. [1]

Idling cars create pollution around schools

Studies at school’s have shown that many parents tend to idle their vehicles when waiting to pick up their students and there are elevated levels of air toxics during these afternoon pickup times. While children’s lungs are especially susceptible to air pollution, limiting idling can dramatically reduce these pollutants and children’s exposure to them. [1]

Why Idling Vehicles is an Environmental Justice Issue

​​Idle vehicles relate to environmental justice due to our reliance on fossil fuel consumption. The production, use, and extraction of fossil fuels have numerous consequences on the environment they occupy. The areas where fossil fuels are extracted and processed are called “sacrifice” zones because the health and well-being of the local people and the environment are sacrificed in order to access the fuel. The residents that occupy “sacrifice” zones are often people of color, and the decision to sacrifice the area is most often made by people who do not live in or near the area.

Step 4: Pre-Activity Reflection Questions

Reflection and Educator Observation Questions

Use the following questions to guide students and reflect on what they’ve learned. Provided questions can be accessed in slideshow or worksheet format.

Reflection Questions

  • Describe the air pollution that you notice in your community, can you see or smell it?
  • Why do you think many people leave their cars running when they are stopped?
  • Why do you think it’s important for parents to turn off their cars when they are waiting to pick up their kids?

Educator Observation

  • What answers did you hear from the reflection questions?

Step 5: Take Action – No Idle Zone Lesson Plan

Lead Students in the “No Idle Zone” Activity with guided instructions. Check out “Pro Tips” with each step for useful help!

1. Determine Your Zones

  • Draw or look at a map of your school
  • Make a list of common zones that students get dropped off and picked up
  • If there is more than one spot, split the group into teams so that all spots are covered

It’s amazing how much more people care about something once they’ve given it a name. Naming the different drop off and pick up spots can build a real feeling of ownership and pride. (Plus, it’s fun!)

2. Collect Your Data

  • Gather your observation materials (Data Collection worksheet, stopwatch, pen, clipboard) and decide where students will safely be located at each pick up spot to collect data on idling cars.
  • Review Observation Form with students, ensuring understanding of how to track idling. Working in groups of at least 3 is recommended. One student can take notes, one can keep track of time, and the last can check if cars are idling or not. 
  • Drivers should be told that they are collecting data for a transportation study. These pre campaign observations will be used to track the effectiveness of the campaign. 
  • For the next week, dismiss groups of students from class 10 minutes before school’s pickup time. They will go to their observation spots and collect data on idling cars. It is best if students can do this 3 – 5 days in a row to observe accurate data. 

Take pictures of your team working in your zones. Everyone loves to see themselves and their friends in action. It’s a great way to build a sense of belonging and community. Create a unique hashtag or social media page for your photos.   

3. Compile and Analyze Your Data

  • When all observations are collected, compile data in this Observation Totals Sheet.
  • Go the extra step: Use the EPA’s Analyzing Data sheet to determine how much gas and money is consumed while idling. If this step is too much for the students, do not include the type of vehicle in observations and calculations. (This data can be used as a baseline and is great for students to present to school administration, school board, or other students.)

4. Campaign for Drivers to Stop Idling

Now it’s time to begin the advocacy portion of the campaign! Please find resources below to encourage your broader school community to keep school an idle free zone. Use one or all of the provided resources:

Your Campaign can be spread out over the course of one month, one semester, or the whole school year! Depending on what timeline works best for you and your students.

Hold a contest to see which class on campus returns the most parent pledges! Incentivize the winning class with a prize such as a pizza party from a local vendor or gift cards/coupons!   

Thank drivers who are not idling while reminding those who are idling about the policy!

5. Record Your Results

After the determined time has passed, repeat steps 2b – 4, having students collect data now that the school community has been informed and educated about Not Idling. Record Results on the Observation Totals Sheet Post-Campaign chart.

6. Analyze Your Success

Gather the Post Campaign data and compare it to observations from before to determine if the campaign was effective!

Step 6: Post-Activity Reflection Questions

Student Reflection and Real World Application Questions

Student Reflection
