Yep,
Seems bloody strange doesn't it. Keep it to yourselves but I've had to drop several cases of dizzy driving because of this odd way of working. Basically, you arrest em for dizzy, they say I didn't know. You bail em and ask the courts if they were present on day of sentencing(important point).

If the courts say no then its a very long winded process to prove that they knew they were dizzy. Its far easier to charge no insurance and get em to court that way. Incidentally, if they are shown as disq on PNC/DVLA but CPS decide not enough evidence to charge you cannot then charge em with no licence, as they are disqualified from holding or obtaining one!!!

I have spoken to CPS and it seems that this way of disqualifying folks is on the West Mid court circuit so I am not sure if its done the same in other parts of the country.
