Thread: 110 mud flap clearance from ground?

My understanding of minimum length is centre of the axle where fitted .

Chopping them removes most of the benefit

14.2.1. General Requirements
All wheels of a motor vehicle or trailer (including a ‘Prime Mover’ capable of operating without a ‘Semi-trailer’) must be provided with wheel guards which must be so designed as to protect other road users, as far as practicable, against thrown-up stones, mud, ice, snow and water and to reduce for those users the dangers due to contact with the moving wheels.


14.2.5. Notwithstanding the requirements specified above the wheel guard including a mudflap (if fitted) need not be less than 230 mm from the ground for other than off-road vehicles, or 300 mm in the case of vehicles designed for off-road operation.

BTW...the above seems to refer to the upper limit of length. In another section I saw re ground clearance, the minimum ground clearances were referred to 'with exception of mudflaps'. So from what I see, and I stand to be corrected...you can let them hang as low as you like(no jibes please)....but the bottom edge no higher then 300mm off the ground for a 4wd.

And from truck driving experience, our mudflaps used to be very close to the road, and we were never pinged for it.

So, it seems from that last bit that I can legally remove quite a bit - not that I would though.
Sounds good.

I recently made my own rear m flaps from 6.4mm thick "Insertion rubber" as the trade call it.
Relevantly they are longer than std and at risk when reversing in mud or sand so I needed to mod them near the lowest edge so as to be able to chain or rope them up if needed.
I looked at drilling 3 m8 size holes in ea flap but had a better idea.
I used a hole punch and hammer to make the holes and they are neat cutouts. The hole punch is a part of a grommet/eyelet kit for tarps and cost 14 at kmart camping dept or somewhere years ago. Easy.

Why would you cut them? Long mudflaps are a good thing.

Mine doesn't have front flaps....1/2 is probably better than none at all.
