No-one actually bothers to read the specification for L plates - after all, you can buy legal ones all over the place so there's no real call for anyone to study the specification so they can make one up themselves.
The specification however is here: http://www.opsi.gov.uk/si/si1996/Uksi_19962824_en_12.htm
You may be wondering what the heck I'm getting at - but just bear with me a moment! The interesting clause here is the last one:
"The corners of the ground can be rounded off."
Ordinarily, you'd probably just assume this means you can have the normal L on a slightly rounded plate - the corners don't need to be dead square. And in fairness, it's probably exactly what they meant. However - being picky for a bit, that's not what the above says.
To start with, it doesn't specify a lower limit on how much the corners can be rounded by. So taking it literally, you could have all 4 corners perfectly rounded until they met up with the next one - a circular L plate. As long as the diameter was 178mm, it should be legal!
However, the fun doesn't stop there. The specification doesn't state that it's just the corners at the *edges* of the white ground that can be rounded off - and we've got more corners in there than those. The OED defines a corner as "a place or angle where two or more sides or edges meet." By that definition, we have many more corners, we have the corners where the edges of the white ground meet the red L! So, again taking this literally, it should therefore be possible to have a the corners of the L rounded - again rounded as much as they can. This would also apply to the "inner" angle of the L as well as the outer ones - forming a red sausage shape.
So, the big question - is it legal to hang a red sausage shaped object on a circular white disk (providing the dimensions are correct) as a means of showing that you haven't yet got a full license?
