Drink Driving

Drinking Driving – two dangerous ‘D’s when mixed together!

At Aquarius we are not against drinking, having a social drink with friends is fine if you’re in control and sticking to the recommended safer guidelines. What we are concerned about is the mixing of alcoholic drinks with driving.

There is an old myth about “I can have one drink and still be safe to drive” – false! We often get asked “How many drinks can I have and still be safe to drive?” – well basically there isn’t a safe amount.

If you are pulled over and breathalysed, the machine takes a reading of how much alcohol appears on your breath but this will vary for every person.  We are different weights and sizes, we may have been drinking with a meal or on an empty stomach and none of us can predict what the alcohol levels of our breath or blood will be.

An example of this would be if you were a petite 5′ 2″ female and you drank the same as a hefty 6′ 2″ man; the alcohol in your blood stream will be more concentrated because you simply have less blood due to your size and women have a higher fat/water content than men (sorry ladies but its true). You both consumed the same drink but the petite young lady will usually have a higher reading than our hefty chap.

Whoever you are, just one drink can effect your judgement and your reactions so its always better and safer to wait until you are alcohol free before you drive.

For every unit of alcohol you drink it takes one hour to leave your system (plus an additional 20 minutes from the first drink)

Red-hair-boySo here we have Charlie, he goes for a drink after work with his colleagues. He chooses to have a pint of standard strength lager (3.5%) that’s 2 units which he has at 5:00pm. After this he has a double vodka and coke (50ml) that’s 2 units. 

Charlie finishes both these drinks by 6:00pm…. but when can he actually safely drive his car home?

4 units = 4 hours + 20 minutes from the time he started drinking. So 9:20 pm should be the earliest time that Charlie considers driving again. 

However there can also be factors that mean our liver doesn’t work as efficiently as normal.  If Charlie is on medication or if he has liver damage or if he is still young (with organs not completely developed) these factors might mean it takes his liver longer to break down the alcohol.
