At 45 degrees, 1 m or 20m, the same amount will be obscured.[bigwhistle]

From the RMS Number plates and labels - Registration - Roads - Roads and Maritime Services

Display of number plates

Number plates must be permanently fitted to vehicles in an upright position and parallel to the vehicle’s axles, and not more than 1.3 metres above ground level.
Number plates must not be obscured, defaced or otherwise not legible.
The numbers on number plates must be clearly visible from any point that is up to 20 metres from the number plate, and within an arc of 45 degrees from the surface of the number plate above or to either side of the vehicle.

I was more correct mick stating 20 degrees...

Yes, 20 degrees was wrong, written in a hurry. And yes, the mud flap is still on backwards, because I'm too lazy to change it.

That bit of legislation seems to be very poorly drafted.

As I read it, a 45 deg arc is an arc which subtends 45 deg at the centre of the circle it is part of.

The wording quoted is very vague as to the plane from which the angle is measured but assuming they are concerned about visibility from behind, you would have to assume they are talking about an arc which is 22.5 deg either side of a line perpendicular to the face of the number plate.

Visibility in this arc would normally be relatively easy to achieve with the standard spare wheel fitting and probably not too hard by spacing the number plate off the back in the standard location.

Just thinking....

It isn't legal for cars or bikes. No doubt mostly because number plate recognition cameras wouldn't be effective.

Do you remember when Motor Cycle front plates were fitted front to back ( vertical & parallel with the bike length) on the mudguard. Rear one was facing the rear.

The front ones (usually steel) would have cut you in half if a bike ran ito you.

Not a good plan in this age.[bigsad]

Just sayin'.

Hi,
It was that piece of moribund legislation that required the front number plate to be lit by the headlamp vs another regulation prohibiting any sharp object that could cause pedestrian injury, that was the trigger (along with lots of other arguments) for dropping the front number plate requirement for motorcycles in Tasmania in the early 1970s. Other States followed the example,

A pedant would argue that the words in the article Wallyb refers to, do not match the diagrams. A 45 deg arc forward from the edge of the number plate would not be very sensible.

The diagrams are clear, a very poorly worded explanation ! What direction is "forward" in relation to the rear plate when fixed to a vehicle ?

Oldie

The actual legislation I think is even clearer as it says "as shown" in the diagrams. So that stuff us up arguing about their words

"within an arc of 45 degrees from the surface of the number-plate above or to either side of the vehicle, as shown in figures 1 and 2 of Diagram 1 (in relation to heavy vehicles) and figures 1 and 2 of Diagram 2 (in relation to light vehicles)"


NSW Legislation

and to answer a previous question: "in an upright position that is substantially parallel to the vehicle’s axles" which for some of you, given axle articulation, could be anything [biggrin]
