Report Mum to DVLA, now what happens?

[NellyTheCake]

I've had concerns about mum's driving for a few months after seeing some scraps appearing on her car. She said someone crashed into her when she was parked.
I asked her GP to assess her, which they did about a month ago and said she was ok to drive for now but told her she needed to stop if she didn't feel safe.

I visited her this weekend and she told me her car had broken down in the supermarket car park. She was given a cup of tea while some staff helped move it out of the way. The local garage came and looked at it.
All seems ok with this story except that she told me exactly the same story a couple of weeks ago, except that time there was no cup of tea. But she is adamant that the same thing happened twice.

Then I looked at her car. There is extensive damage to the front, both on the driver and passenger side. She's obviously crashed it at least once. But she is insisting that the car is faulty and needs to go to the garage. She hasn't said anything about the damage and I don't want to mention it as our relationship is fragile at the best of times.

So I reported her. And I spoke to her GP and told them what I'd found.
I can't find anyone at the supermarket who can tell me what happened there.

The car is sitting on mum's driveway. I've no idea how she managed to drive it home because of the damage.

The DVLA say they contact the driver and the GP but won't tell me anything.
Does anyone know how long this will take? Do they just write a letter?
My concern is that she could be done for leaving the scene of an accident. But atm mum seems to be in denial that anything has happened to the car other than it breaking down.

@I8toys I completely agree - DSis helped DF renew his licence the last time but we should have seen that him being unable to renew himself was a sign.

@NellyTheCake good luck and I hope the GP helps in the end. Nurses who had known DF for years helped us with DVLA.

@NellyTheCake I don't know why the GP is assessing as fit to drive. They are not trained to do this. A driving assessment is fine at specialist centres by people trained in the assessments.
The memory assessment tests do not do this. As a GP in severe cases of dementia it's obvious. In more mild cases it's more subtle.
The DVLA are taking ages and they really don't do very much.
Over the years as a GP I had several relatives discuss their worries about their parent's driving with me. If the family had driven with them and were seriously concerned I would advise appropriately.
They didn't always listen. It's a really difficult situation.

We had to contact the police after our elderly family member had an accident but couldn't remember what happened. Gp wasn't very helpful and dvla takes time so we spoke to someone at our local station who came out and had a word.

Unfortunately family member forgot and then Crashed again the week after so we took the keys against their will.

They were diagnosed with dementia shortly after.

My husband is a dementia nurse and even when someone receives a diagnosis it is up to the patient to self report their diagnosis to the DVLA. Utter madness as nobody wants to stop driving obviously.
This is in Scotland btw
