What you can report
Some vehicles, particularly with diesel engines, may emit some smoke under certain driving conditions as part of normal operation – for example, driving uphill. Steam can also look like smoke, especially on cold mornings.
You can report a smoky vehicle to us if it's:
- emitting smoke continuously for 10 seconds or more
- less than 4.5 tonnes – for example, motorbikes, cars and vans
- registered in Victoria.
To report smoke from large trucks and buses over 4.5 tonnes, contact the National Heavy Vehicle Regulator.
You should report a smoky vehicle within 14 days.

What to include in your report
The more information you can give us, the quicker we can respond. When making your report, tell us:
- about the vehicle, including number plate, make and model
- what time and date you saw the smoky vehicle
- where the vehicle was and what road it was travelling on
- your full name and contact details so we can contact you if we have any questions (we will not give this information to anyone).
Reports cannot be anonymous.
What happens next
After you have made your report, we send you a confirmation email with a reference number.
We review the report and check the vehicle details with VicRoads.
We advise the owner to get their vehicle checked and repaired if required.
