  • Fleet utilisation

    Metrics that indicate how effectively a fleet's vehicles are being used, revealing which vehicles are being used as expected, overused, or underused. 

  • Fuel card

    A payment card specifically used as an approved method for fleet drivers to purchase fuel, allowing fleet managers to track and manage fuel expenses.

  • Fuel economy

    A measure of the distance a vehicle can travel per unit of fuel (e.g. miles per gallon).

  • Fuel efficiency

    A measure of how effectively a vehicle converts fuel into usable energy, often measured by the amount of work performed or energy produced per unit of fuel.

  • Fuel management

    Using metrics and information to monitor and reduce fuel consumption across a fleet.

  • Fuel theft

    Unauthorised actions to obtain fuel including siphoning fuel directly from a company vehicle and fraudulently fueling up a non-company vehicle.


  • G-force sensor

    A device used for driver behaviour monitoring that measures the force exerted on a vehicle during acceleration, braking, or turning.

  • Geofencing

    Virtual boundaries on a map that are set in order to monitor vehicle movement and create alerts when vehicles enter or leave specific areas.

  • Global Positioning System (GPS)

    Satellite-based technology used to track vehicle location and movement.

  • Green fleet

    A fleet that prioritises environmentally friendly practices to reduce emissions and fuel consumption.

  • Gross Vehicle Weight Rating (GVWR)

    The maximum authorised weight of a fully loaded vehicle as specified by the manufacturer, including the vehicle's chassis, body, engine, engine fluids, fuel, accessories, driver, passengers and cargo but excluding that of any trailers.


  • Hours of Service (HOS)

    Regulations that govern the number of hours a commercial vehicle driver can work in a day or week to ensure driver safety and prevent fatigue.

  • Hybrid Electric Vehicle (HEV)
