Oh right.. I take it the S88 still let's you carry on driving then..? How do you get issued with one if them if they don't sort your medical out on time..?
Looks like we are both on a late one, eh? I was just about to shut my eyes when I saw this.
Anyway, S88 is just Section 88 of the Road Traffic Act. You should just do a Google search on this and you will find the DVLA leaflet and it will describe the circumstances as to how you may qualify to drive. From memory though :
Your previous licence must not have been revoked and you must not have any current convictions /pending prosecutions.
You need to discuss your "fitness to drive" with your GP and it is agreed you are.
You must be sure that your application would not be refused.
You do not have any new medical conditions you need to notify DVLA about.
You need to have applied and your completed and correct paperwork is already with DVLA.
I can't remember how it works with HRO though you should check the site /ask the question directly. It may well be fine you have been you are on a one year licence and have kept your nose clean as this current licence has not been revoked but you need to check this out - I am not familiar with anything to do with drink driving.
Also as far as I understand you do not actually get issued with anything to cover you for S88, it is not a decision made by DVLA, they say it is essentially between you and your doctor.
The most you will ever get from DVLA (either in one of their letters addressed to you or verbally by medical line staff) is that "you could be entitled to drive under Section 88 of the RTA". I was told by staff in December last year that "I SHOULD be able to drive" which I found surprising.
Anyway, check out the DVLA leaflet online and most importantly find out on this forum about being (formerly) classed as HRO and the S88 / current one year licence.
