SOME RECENT COMMENTS ON SOCIAL MEDIA HAVE PROMPTED ME TO AGAIN EXPLAIN THE LEGALITIES OF TOWING MIRRORS.
TOWING MIRRORS, DO YOU REALLY NEED THEM? - Yes or No?
Currently, you will see many drivers towing large caravans, horse floats, boats, and other large trailers without using additional towing mirrors.
We also watch lifestyle TV shows, television advertisements and see glossy sales brochure photos of vehicles advertised for their towing capacity towing large caravans on the roads and highways, that are not shown with the legally required towing mirrors fitted in many cases.
Towing mirrors, as such, are not legally required, HOWEVER, the visibility that they provide IS a legal requirement.
If the distance between the inside of your vehicle side mirrors is not wider than the widest part of your trailer or caravan, then you must use towing mirrors on the roads when towing. You must be able to see all the way down your caravan, horse float, boat or trailer to and including the rear corners. and the road beyond.
This diagram by Robert Pepper – Automotive Journalist, clearly shows the legally required field of vision from the driver’s seat when towing a caravan or any large trailer. This vision must also extend to the road behind the trailer.
Field of vision from the driver’s seat without extra towing mirrors is shown on the driver’s side or top side. The area in red is the blind spot caused by the wider trailer.
The passenger or lower side shows the visibility with the correct extra wide or towing mirrors fitted. The legal requirement is to be able to see ALL areas in green from the driver's seat.
The top section shows without extra towing mirrors and clearly shows the red blind spot. From the driver’s seat, the driver’s field of vision, via the standard vehicle mirrors is blocked when the caravan is wider than the inside measurement of the mirrors used. This blocked vision / blind spot is shown in red and can hide a car, motorbike or cyclist or other vehicle overtaking.
The bottom section shows the extra field of vision in green, offered by having wider towing mirrors fitted, and no blind spot created by the wider caravan under tow.
It is a legal requirement in all states and territories in Australia to have the field of vision as shown in the bottom section, in green, which extends to 4 meters wide at 20 meters from the driver’s position.
You may still fit a camera to the rear of your caravan for extra rear vision when reversing. However, it DOES NOT replace your legal responsibility to have the visibility required down the sides of your car and trailer as in the above diagram.
While with the recent changes to ADR 14 / 03 now allowing some approved cameras on some vehicle categories to provide visibility to the rear, most vehicles on the roads today still require the 'by reflection' definition afforded by mirrors. If the standard mirrors, or approved cameras do not give the visibility as shown in the diagram, extra wide mirrors or approved cameras may be required to be fitted.
Always use your mirrors when driving on the highways to help ensure you can see who is beside or behind you and may be ready to overtake or already in the process of overtaking.
Remember to remove any wide mirrors or slide adjustable wide mirrors in when not towing.
With ALL mirrors there will be a blind spot so always do a head check before turning or overtaking.
Good mirrors are also invaluable when reversing into a tight caravan park site.
KEN’S TIP No1 : - I use the Clearview Next Gen mirrors as a permanent replacement for the standard Ford Ranger side mirrors. They are extendable for when towing and have a split two-part mirror. I have the bottom smaller mirror set to show me the caravan tyres to give vision of the tyres when parking close beside a concrete slab, gutters, the road fog line or other locations.
When ordering you can often also get an electric fold wiring harness if your vehicle does not already have electric fold mirrors as standard. This gives you the opportunity to fold the mirrors electrically in, to access tight parking or help avoid damage from people at shopping centres etc.
KEN’S TIP No 2 : - When reversing into a tight caravan site, we often need to reverse from the right-hand side. With the slab on the left of the site, the mirrors do not usually allow visibility of the slab to reverse beside.
I use an Oricom WRC001 Wireless Reversing Camera that can be placed anywhere. It has a magnetic base to be mounted anywhere temporarily. By placing it on the slab showing the side you want to line your wheels up with, it makes reversing so much easier. The camera shows via an App on your phone and can be placed anywhere in range.
It is also useful when off roading and you need visibility of your tyres etc when going through rocky ground. Simple mount it on your drivers of passenger door so you can see where the wheels are at any time. Mount it on a rock or tree branch to see an outside view of your vehicle when you need to monitor low overhangs or diff clearances etc.
This portable camera is available from the Oricom web site. If you use discount code TF15 you will receive 15% discount of normal prices on the Oricom web site.
