Hello my name is ***** ***** I will help you with this.
When you say 'what will they ask' - what do you mean please?
Did the Police attend or did you just abandon the vehicle?
Ok. Then yes they will ask why it was there and what happened. Its the question they will want to know the answer to.
You can say. If it was not drivable you can say so.
But they are likely to ask what it was doing there and the accident circumstances.
Can I clarify anything for you about this today please?
Unless of course I can assist further?
