Are Towing Mirrors Legal?
Are Towing Mirrors Legal in Australia?
Yes — towing mirrors are legal in Australia. In many towing situations, they are not just legal, they are necessary to maintain adequate rearward vision.
The law does not specifically say you must use “towing mirrors.” Instead, it requires that you have a clear view behind your vehicle at all times. If your caravan, trailer, or boat blocks that view, you must fix it — and in most cases, that means fitting towing mirrors.
What Do the Rules Actually Require?
Australian vehicle standards and road rules require drivers to maintain adequate rearward vision while driving, including when towing.
If your load obstructs your view behind or down the side of your vehicle, you are required to restore that visibility before driving on public roads.
Additional mirrors, including towing mirrors, are permitted and commonly used to achieve this.
ADR 14/02 Explained
ADR 14/02 is the Australian Design Rule that governs rear vision mirror requirements for vehicles.
While ADR 14/02 applies to vehicle design and compliance at manufacture level, its principles carry through to real-world use — meaning your vehicle must still provide adequate rearward vision when towing.
A commonly accepted benchmark is being able to see a flat road surface from around 20 metres behind the vehicle, extending at least 2.5 metres out from the vehicle’s centreline.
If your towing setup prevents you from achieving this, you need to address it before driving.
Do You Always Need Towing Mirrors?
No — not always.
You only need towing mirrors when your standard mirrors do not provide a clear view past your load.
- If your caravan or trailer is narrow enough to see past using factory mirrors, additional mirrors may not be required
- If your load is wider and blocks your view, towing mirrors are typically needed
Who Is Responsible for Compliance?
The responsibility sits with the driver.
Because every towing setup is different, no mirror manufacturer can guarantee compliance for every situation. It is up to the operator to ensure their vehicle and trailer combination provides adequate rearward vision.
Are Clip-On Towing Mirrors Legal?
Yes — clip-on towing mirrors are legal, provided they:
- Are securely fitted to the vehicle
- Do not obstruct the driver’s forward vision
- Provide a stable and usable rearward view
They are widely used across Australia as a practical way to restore visibility when towing wider loads.
State-by-State Enforcement
While ADRs are national standards, enforcement is handled at the state and territory level.
Police and road authorities can issue fines or defect notices if your vehicle does not provide adequate rearward vision while towing.
How to Stay Compliant
- Hook up your caravan or trailer
- Check your rearward view using standard mirrors
- If your view is blocked, fit towing mirrors
- Adjust mirrors to clearly see behind and past your load
Final Word
Towing mirrors are legal — and in many cases essential.
If you cannot clearly see behind your vehicle when towing, you should not be on the road until that is fixed.
Fitting towing mirrors is the most common and effective way to restore that visibility.
