In the UK, the alcohol limit for drivers is 80mg of alcohol per 100ml of blood, 35mg per 100ml of breath or 107mg per 100ml of urine. In most other European countries, the limit is less, usually 50mg per 100ml of blood.
The legal drink drive limit cannot be safely converted into units, as it depends on a number of factors including weight, age, gender and recent food consumption.Depending on how much you had to drink, you could still be over the limit the morning after. Sleep, coffee and cold showers do not help sober you up.
Alcohol effects everybody’s driving for the worse. it creates a feeling of over confidence, makes judging and speed more difficult and slows your reactions so it takes longer to brake.
According to Think!, In 2010, 250 people died due to drink driving. By drinking and driving, you risk your life and those of your passengers and others on the road. You risk a fine of up to £5,000 and a minimum 12-month ban and criminal record.
In general, alcohol is removed from the blood at the rate of about one unit an hour. But this varies from person to person. It can depend on your size and gender, as men tend to process alcohol quicker than women; how much food you’ve eaten; the state of your liver, and your metabolism (how quickly or slowly your body turns food into energy).
There’s nothing you can do to speed up the rate alcohol leaves your system.
If you’re thinking about driving the morning after you’ve been drinking, it’s best to consider how much you had, and how late into the night it was before you finished your last drink.
Remember, the strength of different drinks can vary greatly. Some ales for example are 3.5%, but stronger continental lagers can be 5% ABV, or even 6%. White wines vary from around 8% to 15%.
Many of the functions that we depend on to drive safely are affected when we drink alcohol: the brain takes longer to recieve messages from the eye; processing information becomes more difficult; and instructions to the body’s muscles are delayed resulting in slower reaction times.Blurred and double vision can also occur, which means the ability to see things correctly whilst driving is reduced. People are also more likely to take potentially dangerous riskes behind the wheel if they’ve been drinking alcohol.
