Drink driving in UK versus Norway: Drink driving limits


Drink driving limits vary not only between countries
but also between the various parts of the UK
In part 3 of this four-part series comparing the drink driving law in Norway with that here in the UK following the driving conviction of Halfords finance director, Jonny Mason, we turn our attention to the question of the drink driving limit. In other words, how much alcohol can you have in your system and still be allowed to drive?

In Part 1 we looked at whether a golf buggy could be a motor vehicle here in the UK and concluded that it could not unless it was modified. In Part 2 we considered whether a person could commit a drink driving offence on a private golf resort and concluded that while it is possible, it seems unlikely that drink driving on this resort (if it were in the UK) would be a crime. Now, we ask whether Mr Mason would have committed a crime if he had driven a car on a road with the amount of alcohol in his system that he had in Norway.

Throughout these posts, I’ve referred to “UK law”. That’s a bit misleading because English and Welsh law is different to Scottish law, but the drink driving law applies equally to both except in one important respect: the drink driving limit. In Scotland, the limit is 50 mg of alcohol per 100 ml of blood (22 mg per 100 ml of breath). In England and Wales, the limit is 80 mg of alcohol per 100 ml of blood (35 mg per 100ml of breath).

As a child, I was told various things about how much you can drink before you drive (interestingly I don’t recall ever being told not to drink anything before driving until I was much older). The (mis)information I remember most clearly was that you can drink two or three pints of beer before driving. Two pints was the most often cited figure, but I do remember going to the pub with my science teacher who was about to drive home when we finished drinking insisting that three pints was completely safe and would not put anybody over the limit! He was a biologist by training and should have known better. I was also told that eating before drinking will reduce the alcohol level.

In fact, the amount of alcohol you can consume before reaching the drink driving limit varies from person to person and eating food will have no effect on you blood-alcohol level. Food may make you feel less intoxicated but it does nothing to alter the amount of alcohol entering your body and thus the reading you’ll provide should the police ever test you.

Generally speaking, men can consume more alcohol than a woman and fatter people can consume more than muscular people without exceeding the drink driving limit. This is because the alcohol level in your body is a function of the amount of water in your body and fat contains more water than muscle. While you can estimate the amount of alcohol you can consume you cannot be accurate, which is why the best advice is not to drink any alcohol if you plan to drive.

So, what was Mr Mason’s alcohol level? None of the reports I have read set out his alcohol level, but we can estimate it because the reports do say he was double the drink driving limit. In England that would mean he had around 160 mg in 100 ml of blood. But, a little research reveals that the drink driving limit in Norway is much lower. There the limit is 20 mg of alcohol in 100 ml of blood. That means that double the limit is 40 mgs.

At 40 mg of alcohol in 100 ml of blood, Mr Mason would NOT have exceeded the drink driving limit in England and Wales nor even the lower limit in Scotland. So, had he driven a car (not a golf buggy) on a road (not a private golf resort) he would not have been committing an offence anywhere in the UK.

In the final part, we will pretend that the prosecution could secure a conviction and look at what sentence would be imposed.

Ched Evans

Before I begin, I will say that at around 4,500 words this is probably the longest blog I’ve ever posted but I think it’s all necessary to set the scene for this case and explain the background that has been largely ignored or airbrushed in the press. Despite its length, I have not attempted to include every little detail of either fact or law but have done my best to provide a balanced picture of the Ched Evans case, what happened and why the courts reached the decisions they did. There has been so much written about the Ched Evans case over the past weekend, much of it based on a very shaky grasp of the facts and law, that I decided I would read up about the case and weigh in (hopefully on a slightly firmer footing than most of the articles I’ve read so far).

Broadly speaking there seem to be three groups who have opinions on the case:
1.Sexual violence groups (including people describing themselves as “radical feminists”) who appear to take the view that the case is awful, the Court o…

How do the police decide whether to charge a suspect?

A question I’m often asked by clients (and in a roundabout way by people arriving at this blog using searches that ask the question in a variety of ways), is “how do the police decide whether to charge or take no further action (NFA)?”
What are the options?
Let’s have a quick think about what options are available to the police at the end of an investigation.
First, they can charge or report you for summons to attend court.  Charging means that you are given police bail and are required to attend court in person.  A summons is an order from the court for you to attend or for you to send a solicitor on your behalf.  In many cases where a person is summonsed, the court will allow you the option of entering a plea by post.
Second, you may be given a caution.  These can be a simple caution, which on the face of it is a warning not to be naughty in future, or it can be a conditional caution.  Conditions could include a requirement to pay for the cost of damage or compensation, etc.  Either…

Bid to prevent defendants knowing who accuses them of a crime

When I read The Trial by Kafka and Nineteen Eighty-Four by Orwell, I took them as warnings of how a bad justice system wrecks lives of those caught up in it. Sadly, some Members of Parliament and the House of Lords seem to view the books more as a guide to how they would like our Criminal Justice System to run. Today, I read of plans to hide the names of accusers and witnesses from defendants in a large number of cases. Victims of sexual offences, such as rape, have had the right to lifelong anonymity for many years now. This means that it is a criminal offence to publish information that will lead to a complainant being identified. A Bill currently being considered by Parliament would extend that anonymity to bar defendants and their lawyers knowing the name of the person accusing them. This would apply not only in sexual offences, as has been reported in the press, but also in violent offences.
The anonymity currently offered to victims of sexual offences is not total, the complainant…
