The court will want to know what has changed in your circumstances since your ban.
saying it is hard without a licence will not cut any ice, after all, it was meant to be a punishment!
you should show what you have done to minimise the risk of drink driving again, by addressing any alcohol issues.
You should show if it will be of benefit for work, supported by a letter from your employer. The sort of thing that is good is if someone else can be employed if you are able to drive.... the benefits to others always cuts more ice.
Perhaps your employer is relocating and unless you get your licence back, you will have to leave the job.
You will have to give evidence about your circumstances and expect to be cross examined about why you cannot continue to use public transport.
You will get a decision on the day, but even if they grant a reduction, it may not be that you get it back immediately (but they generally do do this). You then have to submit an application to DVLA and wait for them to send you details of the medical you must undertake as a High Risk Offender before you get your licence back. read up on other threads on here about people’s experiences......., that process can take months.! And you cannot drive until all that is complete.
I presume you had a high reading, hence the DID’s course so you can be pretty sure that DVLA will want to enquire with your GP, as well as undertaking their medical.
