In the UK, over 200 people were killed in 2013 after accidents that involved someone who was over the legal limit for drinking and driving. The number of deaths was around 240. In the past 35 years, the number of people who've died due to accidents involving drinking and driving has gone down but the current numbers are still quite high.
Between 1979 and 2012, the number of people who died or suffered serious injury due to drinking and driving went down by over 3/4.
Within England and Wales, drivers are not allowed to exceed the limit of 80 mg of alcohol for every 100 mL of blood 35 microgrammes for 100 mL of breath and 107 mg for every 100 mL of urine.
Other than these two countries, the limit is significantly low, just to be extra safe; and it is limited to 50mg per 100ml of blood.
Scotland is has different drinking limits for the drunk drivers, in comparison to the rest of UK. 50mg of alcohol per 100mm of blood is what the limit went down to in December of 2014. For breath tests, the limit was set at 22 micrograms/100ml of breath.
The Scottish Government have altered their drink drive limit in order to bring Scotland in line with most other European countries, this has aided in saving lives and make Scotland's roads safer.
Drinking and still remaining below the limit has no perfect way of measuring it. However, different people will consume different volumes of alcohol to remain under the limit, as it depends on body system.
Following factors are needed to identify the drinking limit;
The best caveat is to abstain from alcohol whenever you will be driving because your driving can be affected by even a tiny volume of alcohol.
Alcohol badly affects the body's functions which are used during driving:
You can experience blurred and double vision, this affects the drivers ability to visualise things normally. Since alcohol unleashes urges you usually keep in check, you are probably going to do something that potentially puts your health at risk.
Even a small quantity of alcohol will affect your ability to drive, and it would be safer if you avoided any alcohol if you are going to drive.
You can be subjected to a screening breath test by the roadside if the police look forward to investigating whether you are over the drink driving limit. The device that is used to check the drinking limit is called breathalyzer.
They will escort you to the nearest police unit and perform a more thorough screening of your breath when the normal breathalyser results are inconclusive or if they have valid reasons to suspect that you are operating a vehicle under the influence. There is a more advanced breathalyser at the police unit and you must give two additional breath samples.
To determine whether you have exceeded the limit or not, they use the result with the lowest readings between the two.
Where the evidential breath sample is in the region of 40% over the limit, you will be provided with an opportunity to replace the breath specimen with blood or urine and the decision to the test to be taken will be determined by the police. You will be charged only when the samples indicate that you are above the given limit.
The police can also carry out a breathalyser test if you have been involved in a moving traffic offence [going through a red light or making banned turns], been involved with in an accident or have given sufficient grounds to the police to believe that you are driving over the limit.
Check points where drivers are screened for drink driving are usually set up around the major holidays and the police can stop whichever vehicle they choose to stop.
You will be ordered to pay a sum of 5,000 pounds and barred from operating a vehicle for twelve months when they find that you have exceeded the blood alcohol limit while operating a vehicle. Somewhere between 3 and eleven penalty points may be given. Police can also send you to the jail for more than six months. If your drinking limit and involvement in accidents and other violations is high, then, you will be charged with all of the punishments mentioned above. If you are stopped for drink driving more than once during a 10-year period, you are likely to be banned from driving for at least three years.
