Idle time (engine idling) is how long a vehicle keeps its engine running while stationary, without moving: in traffic, while parked, during loading and unloading, or out of driver habit. It’s fuel burned and wear accumulated for zero kilometres produced.
Why it’s a problem
Idling burns fuel, raises emissions and engine wear, and worsens cost per kilometre with no operational value. Across a fleet, even a few minutes per vehicle per day add up to thousands of euros a year.
How it’s measured and reduced
Telematics data automatically records idle time per vehicle and driver, making it a trackable KPI. It’s reduced through driver training, shut-off policies and start-stop systems. It’s one of the eco-driving levers for cutting fuel use.
FAQ
How much fuel does idling use?
It depends on the engine, but a commercial vehicle idling typically uses around 1-2 litres per hour: high idle times noticeably affect annual cost.
How do you monitor a fleet’s idle time?
With telematics, which records engine-on-while-stationary time for each vehicle. Comparing vehicles and drivers pinpoints where to act.
