If the post had been read, he would see that Bonnie001 says that he did drink just over half a bottle of wine after getting home, but he is still in the mire. Why?
Because, since 1988, when the Police find you, post incident, they can breath test you, up to many hours later. The below legislation, in plain English terms says: "When the police require you to provide a breath test when you are, or have been the driver of a motor vehicle on a road or public place, the amount of alcohol in your body then is presumed to be what was in your body when you are driving. If your DEFENCE is; "I have been drinking since I drove" then it is for YOU to satisfy the court that you have been drinking since, AND that the amount you drank made the difference to you being over the legal limit. Without witnesses, that is difficult to prove, and would need a technical expert to give evidence on your behalf (Circa £800 cost) plus, if you lose, the cost of the technical expert called by the prosecution to rebut the defence you put forward.
On a personal note, I feel that this legislation is draconian and can leave people in a very difficult position. That is why I have used my expertise in the past to advise Solicitors on the merits of their "technical defence" in these circumstances, prior to them spending clients money on an expert for court.
This is what the law says in legal language:
Use of specimens in proceedings for an offence under section 4 or 5 of the Road Traffic Act.
(1)
This section and section 16 of this Act apply in respect of proceedings for an offence under [F1section 3A, 4 or 5 of the Road Traffic Act 1988 (driving offences connected with drink or drugs)]; and expressions used in this section and section 16 of this Act have the same meaning as in [F2sections 3A to 10] of that Act.
(2)
Evidence of the proportion of alcohol or any drug in a specimen of breath, blood or urine provided by [F3or taken from]the accused shall, in all cases [F4(including cases where the specimen was not provided [F5or taken]in connection with the alleged offence)], be taken into account and, subject to subsection (3) below, it shall be assumed that the proportion of alcohol in the accused’s breath, blood or urine at the time of the alleged offence was not less than in the specimen.
That assumption shall not be made if the accused proves—
(a)
that he consumed alcohol before he provided the specimen [F7or had it taken from him] and—
(i)
in relation to an offence under section 3A, after the time of the alleged offence, and
(ii)
otherwise, after he had ceased to drive, attempt to drive or be in charge of a vehicle on a road or other public place, and
(b)
that had he not done so the proportion of alcohol in his breath, blood or urine would not have exceeded the prescribed limit and, if it is alleged that he was unfit to drive through drink, would not have been such as to impair his ability to drive properly.]

As to the "Citation needed" , All the police have to show, as above, is that you are, or have been, the driver of a motor vehicle on a road and, if they suspect alcohol in your body (not even that after an accident) they can require you to provide a breath test. If you refuse, then you lose your possible defence that you have been drinking because the failing to supply offence is complete. It is immaterial if you have been drinking afterwards because you are not being charged with being "over the limit", but with "refusing a breath test."
