3 drinks will not have you failing a test at an appropriate time the next morning unless you are drinking rocket fuel or the drinks are at stupid o'clock in the morning.
If you say so, must be rocket fuel and you must be doing the test at 2am lol.
If Burnsy is a police officer I will respect his expert opinion on this and conceed if I'm wrong to suggest one could fail a breathalyser test the next morning after a few drinks the night before. I trust you would do the same and rethink your outlook on the matter.
Well I know I metabolise alcohol very quickly having used this testing tool which was quite interesting, however others may not metabolise as quickly, clearly you and I carrying a bit more mass, and probably having a healthier liver than most will probably cope better with an extra level of alcohol - however, if you drink regularly (and let's be frank, in this Country so many people do to excess!) then it's sensible.


He's a Special Constable.
And the hand held ones really are quite accurate, but you've got to follow a proceedure (ie. not smoke right before the test, not have had an alcoholic drink in the past 20 minutes or so etc).
Also, do these breathalysers still have cartridges that need to be changed every so often?
Yes totally. And FYI, I've drunk 2 pints and been under the limit within 30 mins of drinking them (not amber), not to say that I'd drive anyway. I'd suggest you'd be similar.
However, this is more for people who have biiiiig sessions, like 20+ units.

I agree again, but overslop was quick to point out that he is on about a few drinks with mates where this will be good for him![]()

Flat-out wrong again.....
Going to the pub = a few drinks with mates.
And yes, a few drinks with mates can lead to failing a test the morning after.
On the contrary, you singled that out of the three things I mentioned.![]()


I'm proving that one wrong. The rest I just said drink less rather than getting wasted![]()

HINT: Don't post this in Motors.

I'm proving that one wrong by using knowledge of units in alcohol and how your body processes them, which you feel deserves a rolleyes. A little knowledge is a good thing, not a rolleyes thing
The rest I just said drink less rather than getting wasted![]()
for.
Is it really that difficult to just not drink a night before you're gonna be driving?
No need to not drink, sounds like you need to be wasted to have fun though. Maybe you should look at why that is....
And you always know exactly that you'll need to drive the following day? Never have an emergency come up after a heavy night out? Or is everything just black and white like the following poster's world?
Maybe you should look at having that stick removed. Need is a very emotive word, and one that is completely unjustified here. Grow up & don't judge people by your own standards, or lack thereof. In fact, if I were you I'd stop the judging full stop. Especially when you have no information to work from & are knee-jerk over reacting.
Self righteousness is not a virtue.

A pint is nearly 3 units, so 4 pints would be 12 units. Going to bed at midnight and getting up at 7am would have you with approx 5 units in your system which is the legal limit for men. Eating (which most will) before you get home will make the alcohol take longer to work it's way out of your body.
