The deadline is 31 March if your birthday is late in the year (Oct - Dec me thinks?). If your birthday is earlier the deadline has long expired. The documentation I read gave me the impression that it is ok if you just hand in before 31 March 2009. NOT. I booked for the test but was out of the country a lot and did not get round to it.
I gave mine in towards the end of last year(my birthday is end sept) and had to give them a sworn affidavit as to WHY I was late. There was also an article stuck to the door of the office about you
possibly ending up in court if you are late.
As all the old licenses actually only expire in JUNE and some police stations are more than 2 years behind on processing the applicationsI think you will get a slap on the wrist if you are late but be ready for an earfull

from the police.
Good luck
