Do Not Overtake Turning Vehicle Signs

I don't know about Victorian rules but in WA they are supposed to stop idiots coming up the inside when a long vehicle has to swing wide to negotiate a corner.
The idea is to stop sillibuggas getting squeezed against the kerb and/or being decapitated by the tray as the long vehicle makes the corner. Doesn't always work...........some people can't read.

Hope this helps.

Hi OldPop

The rules are standard across Australia. I can't imagine anything has changed in Victoria and it does not appear to have on their website.

If you are driving a vehicle that is 7.5 metres long or longer such as a semi trailer combination – including any load or projection – and it is displaying a “Do Not Overtake Turning Vehicle” sign, you may use either or both lanes if necessary, to turn left to right if it is safe to do so. If you are not displaying the signs and something goes wrong, you can get fined for crossing the lines.

There are specific rules about where they must be placed.

Thanks everyone for the info

Standard rules across the country.

The important point to appreciate, whether or not you consider you need the DNOTV sign, is that without the sign, if you cross a lane line when turning at a road junction, you can be fined.

In exactly the same circumstances, if you have the sign displayed legally on a vehicle/combination that is over 7.5m in length, you will not be fined for crosing the lane line.

End of story. Fit them. It is just a sign 300mm x 100mm.

The Heavy Vehicle Rear Marker Plates were a WA initiative and are now an ADR and a full description of the rules is covered in VSB12 which can be downloaded at: www.transport.wa.gov.au/licensing and then click on the link to vehicle safety publications. The plates are compulsory on motor vehicles exceeding 12t GVM and trailers exceeding 10t ATM. They are not compulsory on 'route service buses' i.e. metropolitan passenger buses that stop at bus stops to pick up fare paying passengers. They are also compulsory on trailers under 10t GVM when towed behind a vehicle on which the plates are compulsory (because the smaller trailer and its load generally restrict the vision of the plates on the towing vehicle). If a vehicle or combination is over 7.5m in length or must straddle two lanes to turn a corner, the Do Not Overtake Turning Vehicle wording is compulsory and MUST be fitted to the left side at the rear of the vehicle for obvious reasons. The wording DNOTV is illegal on vehicles below 7.5 m long. There are two types being Class 1 and Class2. Class 1 are retroflective with a 'honeycomb' surface appearance (like the bright green 3M tape used on mining vehicles) and Class 2 are just normal reflectorised tape. Class 1 being much more reflective than the Class 2 allows them to be half the surface area of the Class 2 hence easier to mount on vehicles with space restrictions at the rear. There are many size & shape combinations to suit differing vehicle applications but all types = the same surface area i.e. Class 1 = 0.16sqm & Class 2 = 0.32sqm. The plates are permitted on the rear of vehicles below 12t GVM and trailers below 10t ATM but the DNOTV wording is not permitted except as above. Regarding the comment that there is no space to fit them.........there is ALWAYS a place that can be found to fit them with a little imagination and thought even if some brackets have to be made up or a small frame the shape & size of the plate to fit below the rear light bar, etc such as on a table top truck.

The wife took this while we were travelling near Dalby, in between some of the terrible floods, in January.

Good advice for those eager overtakers, before they meet the undertaker.

As mentioned earlier, fitting these signs where permitted, allows you certain rights to cross lines and occupy two lanes.

Having recently done some heavy vehicle training and passed my HR, I can tell you what the instructor said.

1 if you are going to use both lanes to enter a turn, you need to make it obvious by positioning your vehicle, that that is your intent ( there are testing specifications for this to)...if you expect to use both lanes you need to "occupy" them both.

2 expect some ignorant fool to try a come up the inside or outside of you.

This is why these manovers are generaly done at slow speeds.

The other thing they absolutly hammer in both instruction and testing is mirror observations particularly the left one, and particularly in this situation.

Not only are you expected to look for vehicles in your mirrors, there is an expectation that you are looking in your mirrors while negociating certain turns to check the tracking of the rear of your vehicle or combination.


let me tell you there are plenty of situations where you will not get a 7.5m car and trailer combination arround with out using all the road........left turns in one way streets is a good example.

If you are entitled..fit em.

cheers

Don't know where you get the idea it's new rules, been applied for years, probably late 70's early 80's.

Hi All, can anyone let me know where to buy the “Do Not Overtake Turning Vehicle” sign in West Aust metro area. Interested in the (reflective?) stick on type of sign to use on a caravan and not the square metal sign that the trucks use.

Thanks, Richie.
