You can make an application to the court that disqualified you in writing at the 2 year point, as that is more than half of your sentence.
Some courts allow you to apply in advance, in order to have a hearing at the 2 year point. Some do not allow an application to be submitted until the 2 year point has arrived, so a hearing would not be for another couple of months.
You give them your name, address, date of birth and the date you were disqualified, what for and for how long.
Ialways advise putting as much detail as you can in the letter, such as the items below. The reason for this is that the court notify CPS of the application and they have the opportunity, having consulted with the police, to object to the application. The more detail that you put in the letter, the less likely the CPS / police will be likely to object to the application.
You should realise that even if these agencies do not object to your application, the final decision rests with the magistrates on the day And they can still refuse.
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!
What have you done to address your alcohol consumption since the 38 month ban. To get more than 36 months indicates something more serious than a simple 2 convictions in 10 years, and probably involved a very high reading?
So you should show what you have done to minimise the risk of drink driving again, by addressing any alcohol issues, with evidence if you have any.
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 mention family members, You may have good grounds there, but why cannot other people provide this care? Explain if your daughter has a disability that means she cannot take public transport.
How are the needs of your daughter and elderly father met now, why can those arrangements not just continue?
You are not bound by only what you put in your letter, you can expand on it in court but it should not contradict what you put in your letter of application, just expand on it or submit further detail on the elements in the letter.
You can expect to be required to give evidence on oath, and be questioned about what you say by the CPS and the magistrates as they test how much weight to place on what you say.
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.
