could you people pls advise me on the requirements for mirrors for sva ...thanx

You must have a centre mirror (even if you can't see anything through it) and a drivers side mirror.

Through these you must be able to see poles placed in particular places behind the car and areas defined by them. If with these 2 mirrors you can't see the required amount then you must also have a passenger side mirror and be able to see the right bits with that.

The positioning of the poles is complicated and explained in the SVA manual.

Mirrors must also meet the radius requirements. They also need to be E-marked or meet the same requirements (you might have to prove this if not marked).

Hope that helps.
