Vehicle Idling and Fuel Efficiency
A vehicle sitting with the engine running may not seem like a big deal. A few minutes here and there can easily be overlooked.
But across a fleet, across multiple sites and over many shifts, those minutes can quickly add up. Unnecessary idling means fuel is being used, engine hours are increasing, and emissions and operating costs can rise.
Traffic management often involves waiting between activities, setting up worksites, monitoring traffic and coordinating with crews. There are times when a vehicle needs to remain running, and safety and operational requirements should always come first.
The important thing is knowing when the engine actually needs to be running.

Before Leaving a Vehicle Idling
It is worth taking a moment to ask a simple question:
Does the engine actually need to be running?
If the vehicle is going to be stationary for an extended period and there is no operational or safety reason for the engine to remain on, switching it off can help avoid unnecessary fuel use and engine hours.
Small decisions like this become more meaningful when they are made consistently across every vehicle and every shift.
Simple Ways to Use Less Fuel
Fuel efficiency is not just about turning the engine off. The way a vehicle is operated and maintained also makes a difference.
Where it is safe and practical, our crews can help reduce unnecessary fuel use by avoiding excessive acceleration, planning movements carefully, reducing unnecessary trips, and keeping an eye on basic vehicle maintenance.
Something as simple as maintaining the correct tyre pressure can also support better fuel efficiency.
Good vehicle habits protect the equipment we rely on and help keep operating costs under control.
Traffic Management Vehicles Are Different
Not every traffic management vehicle can simply be switched off.
Some vehicles may need to remain running to support VMS, arrow boards, lighting, communications, warning systems, or other operational equipment.
In these situations, keeping the vehicle running may be necessary to maintain the required safety controls. Safety should never be compromised just to reduce idling.
The goal is not to eliminate idling completely. It is to recognise when the engine is not needed and switch it off when it is safe and appropriate to do so.
Looking After the Vehicles We Rely On
Our vehicles are an important part of getting the job done. They help crews reach sites, transport equipment, support traffic control operations and keep projects moving.
Looking after them is part of being professional.
Regular checks, reporting maintenance issues early, driving responsibly and avoiding unnecessary engine hours can all help keep vehicles reliable and ready for the next job.
Small habits can make a real difference over time.
It Starts With the Team
Good vehicle management is something the whole team can contribute to.
Traffic Controllers, TMIs, Supervisors and drivers all have a role to play in making sensible decisions about vehicle use. It does not require a major change to the way we work. Often, it is simply about being more aware of what the vehicle is doing and why it is running.
Those small decisions, repeated across the team, can lead to meaningful savings in fuel, engine hours and emissions.
Final Thoughts
Reducing unnecessary idling is a simple way to operate more efficiently without compromising safety. Taking a moment to consider whether the engine needs to be running, combined with good driving habits and regular vehicle checks, can make a difference across every shift.
Our vehicles are an important part of the work we do, so looking after them matters. Work safely, drive efficiently, and make every minute count when it comes to the equipment we rely on.
FAQs
Why should unnecessary vehicle idling be avoided?
Unnecessary idling uses fuel, increases engine hours, creates additional emissions and can add to vehicle operating costs.
Should traffic management vehicles always be switched off when stationary?
No. Some vehicles need to remain running to support VMS, arrow boards, lighting, communications or other operational equipment. Safety and operational requirements always come first.
How can drivers improve fuel efficiency?
Drivers can avoid excessive acceleration, plan movements to reduce unnecessary trips, maintain appropriate tyre pressures and switch the engine off during extended waiting periods when it is safe and practical.
Why are tyre pressures important for fuel efficiency?
Incorrect tyre pressures can increase rolling resistance and may result in higher fuel consumption. Vehicle maintenance issues should be reported when identified.
Is the goal to eliminate vehicle idling completely?
No. The goal is to avoid unnecessary idling while maintaining all required safety and operational controls.
Who is responsible for reducing unnecessary idling?
Everyone who operates or manages traffic management vehicles has a role to play. Small changes across the team can make a meaningful difference over time.
