Not only forwards and backwards but to the sides. Would a flat sheet (with folded over edges) curved round the tyre pass or do the wings have to have some depth to them?
IVA doesn't care about the tyre.
If you draw a horizontal line across the middle off the wheel, then all of that wheel has to be "under" bodywork. That it if you look
vertically down then that bit of wheel should not be visible from above.
This was the old SVA rule anyway.

That was certainly ok for SVA, and presumably MSVA.
Check out the arches on this firefox which passed first time.

Don't they have to cover something like 2/3rds the circumference within the IVA now? ISTR that when IVA came out, some manufacturers had to redesign theirs to cover more of the wheel than one that would pass SVA....
The rules for IVA are much more complicated than SVA, but IIRC there's a decent diagram in the manual. They have to go to certain angles fore and
aft of the wheel, cover the full width of the tread within that zone, and not terminate more than a certain distance above the axle centreline.
Not sure for MSVA, although I didn't think anything had to be covered.
I've just flicked through the MSVA manual and I can't find any reference to cycle-wings being compulsory.
I'm guessing they would be required under Construction & Use regs and for MOT.
Can anyone confirm this as also being their understanding?
Cheers!
Matt_Claydons post is correct^^^^ rules are 30 degrees fore, 50 degrees aft, not terminating more than 150mm higher than horiz centre line, full width
of tyre covered when viewed from above

You could ring vosa to confirm which rule if any you need to comply with, found them very helpful on the phone in the past..

MSVA mudguards are not required, nor are they needed for MOT, but are a legal requirement under C&U regs LOL
Right, so I have to have them but anything goes for MSVA and MOT. Brilliant, thanks.
