Idle Time Monitoring Software for UK Fleets
Every minute a vehicle sits idling is fuel burned for no journey completed — and across a fleet of any size, that adds up to a real, largely invisible cost. FleetGS automatically detects and logs idle time per vehicle and driver, giving fleet managers the data to cut wasted fuel spend and back up an anti-idling policy with evidence rather than guesswork.
What FleetGS tracks for idle time
Idle time data sits alongside your standard fleet tracking, so it's part of the same dashboard you already use for routes, jobs, and compliance.
Idle events
Every idling period over your configured threshold, logged with start time, duration, and location.
Turns an invisible cost into a specific, actionable number.
Per-driver idle time
Total and average idle minutes per driver per day, week, or custom reporting period.
Identifies which drivers need coaching on stop-start habits.
Per-vehicle idle time
Idle time attributed to each vehicle, independent of which driver was assigned.
Flags vehicles used on routes or jobs that generate excessive waiting.
Threshold alerts
Automated alerts when a vehicle or driver exceeds a configurable daily idle time budget.
Lets fleet managers act on outliers without reviewing every record.
Fuel cost estimation
Idle minutes converted into an estimated fuel cost, using typical consumption rates by vehicle type.
Puts a pounds-and-pence figure on the business case for reducing idling.

A practical way to act on the data
Most fleets get the biggest win in the first month simply by reviewing which two or three vehicles or drivers account for a disproportionate share of total idle time, then addressing those specific cases directly — rather than issuing a blanket policy reminder to the whole fleet.
Turning idle time data into lower fuel costs
Idle time is one of the easiest fuel costs to reduce because, unlike route mileage, it represents zero productive value — every minute idling is pure waste rather than a trade-off against a faster or safer journey. The challenge has always been visibility: without dedicated monitoring, idling happens quietly across dozens of small events a day that never show up as a single line item on a fuel bill.
FleetGS's idle time monitoring closes that gap by logging every event automatically and rolling it into per-driver and per-vehicle reporting alongside the driver behaviour scoring already used for harsh braking and speeding. This means idling coaching becomes part of the same conversation fleet managers already have with drivers about safe, efficient driving — rather than a separate initiative that requires new tooling or process.

Frequently asked questions
FleetGS monitors GPS speed and, for vehicles with connected telematics hardware, ignition and engine status, to identify periods where a vehicle is stationary with the engine running for longer than a configurable threshold — typically two or three minutes. Each idling event is logged against the vehicle and driver, timestamped and location-tagged, so a fleet manager can see not just how much idle time occurred but where and when, whether that's a driver waiting at a delivery site, sat in traffic, or running the engine to keep warm on a break.
