Fleet idling might seem harmless in short bursts, but over time it becomes a significant source of wasted fuel, unnecessary emissions, and higher operational costs. According to the U.S. Department of Energy, a single medium-duty truck can burn up to 0.8 gallons of fuel per hour of idling. Multiply that across a fleet, and the costs escalate quickly.
Whether you’re managing delivery vans, service vehicles, or trucks, reducing idle time should be a priority. Here’s how to address the issue with policies, technology, and training.
Understand the Cost of Excessive Idling
For gasoline engines, idling burns about 0.2 to 0.5 gallons of fuel per hour. For diesel engines, it’s closer to 0.6 to 1 gallon per hour. At today’s average fuel prices, even 30 minutes of idle time per day per vehicle can cost hundreds of dollars per year—per driver.
Beyond the fuel cost, idling also causes:
- Increased engine wear
- Higher maintenance frequency
- Unnecessary greenhouse gas emissions
- Set and Enforce an Idle Reduction Policy
Create a clear, written policy outlining expectations for engine shutdown times, maximum idle limits, and disciplinary measures for repeat violations. Make sure policies are tailored to your operation’s needs (e.g., cold climates may require modified thresholds).
Include these in your driver handbooks or onboarding materials to ensure consistent compliance.
- Train Drivers to Recognize Idling Risks
Many drivers are unaware of how much fuel they burn while waiting in parking lots, loading docks, or drive-thrus. Training sessions should focus on:
- When and where to turn off the engine
- How to use auxiliary power units (APUs) if available
- The link between idling and engine longevity
Tools like the North American Council for Freight Efficiency (NACFE) offer resources to help fleets train drivers and adopt anti-idling technologies.
- Use Telematics and Fleet Monitoring Tools
Fleet tracking systems from providers like Geotab, Samsara, and Verizon Connect offer real-time insights into idle time per vehicle and per driver.
These platforms let you:
- Receive automatic idle alerts
- Generate driver scorecards
- Review idling reports by route, region, or time period
By identifying high-idle vehicles and drivers, you can target coaching or technology upgrades where they’re needed most.
- Install Idle Reduction Technology
Options include:
- Automatic engine shutoff systems
- Auxiliary power units (APUs) for sleeper cabs
- Battery-powered HVAC systems for off-engine climate control
While these may require an upfront investment, the long-term fuel and maintenance savings often justify the cost—especially for long-haul operations.
- Incentivize Low-Idle Behavior
Incentive programs based on idle reduction can motivate drivers to comply. Offering monthly bonuses or recognition for top-performing drivers improves participation and boosts morale, especially when paired with accurate tracking.
Bonus Tip: Offset Fuel Spend with Cashback
Even with reduced idling, fuel costs can be substantial. Platforms like Fluz allow you to earn cashback with a Chevron gift card or get rewards with an ExxonMobil virtual card when purchasing gas for your fleet. Fluz offers digital gift cards and virtual cards that can be used in real-time, without preloading large balances.
