"...which are much more accurate than the ones the cops have."
The early ones worked on a traffic light system, red, red and amber, green and accuracy would be difficult to compare. Later ones are accurate with a numbered result like this one
For reference limit (in breath) is: E&W 35, Scotland 22, train drivers and pilots 9. EWS limits are too high IMHO
Impairment starts well under the English limit
I swear it depends on the type of alcohol as well as the ABV % written on the label.
Old Mout cider I'm convinced has a typo. Should read 0.4% not 4.0%. Has practically no impairment effect whatsoever compared to drinking beer (and probably that precanned GnT) that claims to be around the same %.
Would be interested to do a breath and blood test and a reaction test before and after drinking both as an experiment.
Type of alcohol...umm nope . Alcohol by Volume is he government regulated wa y of declaring the amount of alchol in a beverage. For Beers this should be within .1% abv although can be .2 or .3% if is a cask conditioned real ale , and thats either under or over.
As for these tins of G&T. 1.25 units , so 1 1/4hr for the body to flush the alcohol out the system. If matey on the train is drinking 5 on his way home then he has 4 in his system. So he is probably over the limit. If he is a big drinker then he might not know or feel the efffects of a few G and T's
What was your blood results DazH?
I played around a with breathalyser, not blood tests. Obviously after drinking 6 pints I'd have been over the blood limit. I have known people though who have failed breath tests and then passed the subsequent blood test. Mrs Daz was a drug worker. She had to breathalyse clients before prescribing them drugs which could kill them if they'd been drinking, which is why she had better kit. I'm not going to say how but these things are so easy to fool that any hardened drink drivers are unlikely to fail because they know the tricks. It's pretty scary and one of the reasons I assume anyone driving late at night on a weekend is pissed.
"I have known people though who have failed breath tests and then passed the subsequent blood test."
This could happen for two (three) reasons: Their blood-alcohol had peaked at the roadside and is then being reduced naturally by their body. A delay in getting the blood sample reduces this further, e.g. booking into custody, calling a doctor out, etc. Blood sample analysis has a tolerance in the clients' favour. And a combination of the first two
"I’m not going to say how but these things are so easy to fool that any hardened drink drivers are unlikely to fail because they know the tricks."
Tend to doubt that. The device detects air flow pressure (no sucking or low pressure blowing) and discards the first 1 1/2 litres of breath to get a decent quality sample

😂😂
I’m not sure anyone on this thread is saying that as long as we all don’t drink road traffic accidents will be reduced to 0.
Im not saying that anyone is.
I don’t understand drinking on trains. Of all the places to have a drink public transport is the worst.
That's why one needs a drink!

Iran is worst.
Saudi is pretty bad for it, too
I live in Scotland and I think the "effective zero tolerance" approach is best.
Around 20 years or so there were a couple of times when I drunk drove due to my own nativity/stupidity and the grey area that was drink driving laws at that time.
The first time - I went out, planned to have one or two and get the bus back to my stop, then take the car the last mile or so. Unfortunately one or two ended up as 3 or 4 and I was definitely totally drunk. Luckily I got home safely with no incident but basically shit myself and never did that again.
The second time was I'd been out the night before and had an early start at work. I got to work and could tell it wasn't just sleep deprivation and there was still alcohol in my system. Again no incident but shit myself over that one too. I did feel ok to drive (no excuse, but things were different then).
Fast forward to today, no criminal record, no points I don't really drink much at all.
Like I say, I think the Scottish approach is the best as there is no grey area. I'd like to think I wouldn't have done these things had the laws today been in force, even being young and stupid.
250 ml of 5% is 12.5 ml of ethanol of 10 grams. If you were to absorb all of that instantly, alcohol distributes into about 55% of body weight. So 70 kilos would give a concentration of 10 g/(0.55 x 70 L) = 0.26 g/L or 260 mg/L. The drink driving limit in the UK is 800 mg/L
So no more than three. Two would be prudent, one no issue.
Note that this does not take into account input rate, nor the fact that there will be some elimination.
I teach teenagers about drugs by giving them these facts as part of my day job. A unit is 10 ml equal to 8000 mg of ethanol. Average UK consumption is 11 litres of pure ethanol per year. You can do the sums for units per week yes that is average
Six timea the DD limit says chronic alcoholic. Normally nobody is convicted of a blood level more than three times, because coma is induced at 4x in normal adults. High values are always due to chronic alcoholism as such sufferers can function OK at levels that would sedate most people!
Of all the places to have a drink public transport is the worst.
I reckon me drinking at work is probably a little worse than having a tipple on the train.

You're not an Iranian train driver, are you?
Have we established whether any of these apparent heathens daring to upset STW sensibilities by drinking on trains are indeed driving afterwards? It is just conceivable that their destination is within walking distance of the station they get off at
You’re not an Iranian train driver, are you?
perhaps hes he’s an American train driver who works in Iran?

TiRed - you’ve largely repeated stuff others have already said except despite the point being made clear a dozen times so far in the thread you manage to mistake the jurisdiction for the limit!

Can you read?
We have breathalyzers at work. They cost £400 a pop and go off every year to get calibrated and whilst I'm no breathalyzer expert I'd hope they were relatively accurate.
We have played around with them ''for research purposes' a few times at little staff socials. I also had a proper go a get a properly high reading just to see how I'd feel with that sort of reading. I often have to deal with (and care for over night) teenagers that have got themselves in a bit of a state and it seemed like a good idea to know how out of it blowing 120µg/100ml feels. Main thing I learnt is that different people react sooooo differently to the same amount of booze. Also, the 120µg/100ml (roughy 3.5 times the England and Wales limit) for me at least is properly uncomfortably drunk. In fact getting to the drink drive limit actually took quite a bit more than I expected (I'm a relatively hefty 16st middle aged man) but there is no way in hell I'd ever feel comfortable driving like that. For me it appear I could quite easily drive (in England) on two pints without worry from a legal stand point but I choose not to drink and drive at all.*
*not sure this is 100% true - I would drive first thing in the morning after having my share of a bottle the night before when there must still be traces in my system.
If the limit here in Spain is 0.25ml/l (in breath test), what would one need to drink to be 4x over the limit? Obviously there are variables but a ball park figure.. A bottle of wine? More?
Context : last week a family riding the camino de Santiago were hit by a driver near Leon. The parents were dead when paramedics arrived, their 12 year old son survived with injuries. The driver left the scene but thanks to lorry drivers radioing in sightings of the car, he was arrested and blew a sample four times over the limit. So I was wondering what this bloke had drunk before getting in the car that morning.
The family were from the next town to us, and the boy raced for a "rival" club, parents well involved in the local racing scene, so this has hit us hard in the little world of youth cycling here.
For Beers this should be within .1% abv although can be .2 or .3% if is a cask conditioned real ale , and thats either under or over.
Its a lot more than that, even the big boys aren't that accurate. Carling got taken to court for telling HMRC that their beer was only 3.7% IIRC and only paying tax on that. Yet the cans say otherwise. Turns out they can get it +/- 0.23% between batches so by brewing to 3.7% they could say its 4% whilst still being within the +/- 0.5.
If y<span style="font-size: 0.8rem;">ou're a small brewery with less control then 0.5% is about as accurate as you can expect to be between batches (0.5% is the allowed variation legally for <5.5% abv). </span>
The 2 pint limit that is banded around is something that I grew up with in the late 70's. Whether that was a way for the police to give advice on what the limit was I don't know, but what you have to remember is that drinking and driving was a massive problem and the law was only introduced in 1967. Pretty much everyone I knocked around with stuck to 2 pints if they were driving, with the odd exception who would have a couple more. In fact I don't remember many people at all saying they wouldn't have a drink if they were driving.
I was stopped one Bank Holiday lunchtime after drinking 2 pints of Pedigree and passed the breathalyser, and I don't know anyone who has failed on just having 2 pints.
These days I'm not confident I could pass having had 2 pints, so only have 1 if I'm driving.
Bob - the Spanish limit is essentially the same as the Scottish one. The variables really are too big to accurately work back from a single number to a quantity of alcohol. It depends on his size, when he started drinking, when he stopped, how much he ate, how used to drinking he is, how long from the accident to the evidential samples actually being collected etc.
crudley though it’s unlikely he had less than a bottle of wine.
