The police can stop you if they suspect you are driving under the influence of alcohol. Also, if the police suspect you are about to drive a vehicle (for instance you have your keys in your hands and are just leaving a pub) you can also be stopped and asked to take a drink-driving test. You may also be asked to take a breath test if you are involved in a road traffic accident.
There are three general drink-driving offences:
Being in charge of a vehicle when you are over the legal alcohol limit.
Driving a vehicle whilst over the legal alcohol limit.
When stopped by the police failing to give a breath test.
At the Roadside
The first test that you will take after the police have stopped you will be a breath test. You are breaking the law if you refuse to take a breath test, but if you do refuse you will be arrested and taken to a police station where a sample of your blood or urine will be taken for testing. Note that only a doctor can take a sample of your blood, and only with your consent.
At the Police Station
When you arrive at the police station two samples will be taken. The lowest reading will be used as evidence in your case. You should be given a printout of the alcohol level that has been detected for your own records. Usually the samples are just breath samples, but the police can request that you give a blood or urine sample. This may happen if you are unable to give a breath sample, as you are too drunk. Also, the police may not have a breath device or a qualified officer to operate it available. A doctor may also have informed the police that your condition may be because of drugs and not alcohol.
What Happens if I am Charged?
If your alcohol tests are positive you will be told your rights and cautioned about anything you say can be used in evidence against you. The details of your offence will be recorded on your charge sheet that you will have to sign. You will be given a copy for your records. You will then be free to go and expected to appear at the court at the stated date and time on your charge sheet.
If you are found guilty of drink-driving the penalties are:
A ban from driving for at least 1 year.
A fine of up to £5,000.
Between 3 and 11 points to be put on your licence.
A prison sentence of up to 6 months.
What are the Legal Alcohol Levels?
You can be found guilty of drink driving if you have the following levels of alcohol in your blood:
35 microgrammes of alcohol in a100 millilitres of your breath.
80 milligrammes of alcohol in a 100 millilitres of your blood.
107 milligrammes of alcohol in a 100 millilitres of your urine.
Note that if one of the two breath tests you will take is below 39 microgrammes you will not be charged. If your breath test is between 40 and 50 microgrammes you must be offered the chance to give an alternative blood or urine specimen. However, if your breath test is over 51 microgrammes you will be automatically charged and face an appearance in court.

Hi, I have clean licence and I have been driving for more than 8 years. I blew 49 at roadside and they take to station and after 3 hours they took my blood sample. And release me. What will happen next? I am worried about my blood test. As I am a lone driver in my family I need my license for my job too.
Kumar - 27-Apr-22 @ 12:18 AM
I blew 44 road side from my crash and my bloods came back 96mg. My court case is on Tuesday. I’ll loose my job if I loose my license. Will they take that into consideration? Had no previous conviction or anything. Will I have to do my test again? I didn’t hurt anyone a car speeded past me and made me swerve and hit a Kirb and my car flipped. I wasn’t speeding or anything. I was just going home the morning after I’d had a few drinks

Blew 103 2 nights ago was taken back to the station and tested again twice, this was about an hour after the road side test. First test in station I blew 44 second was 38 so I was lucky enough to keep my license and wasn’t charged. Officer was extremely annoyed and couldn’t believe the result. Is this common or was I very lucky?

ed - 10-Aug-20 @ 10:47 PM
I got stopped for drink driving over 6 months ago now and the court case keeps being adjourned.
I was informed that the police have 6 months from date of offence to ban me. It’s been over 6 months now so will I still get banned?
