Motorists are being warned that a drink in the sun could put you over the limit and you could up in jail. The Breathalyser manufacturer AlcoSense has revealed that no less than 96% of all respondents underestimated the number of units in a pint of (6% ABV) lager and 97% of respondents underestimated the number of units in a 250ml glass of wine (13% ABV).
Both of these drinks contain 3.4 units of alcohol yet the most popular answer was 2 units. With the current Drink drive law there is in effect a 2 unit limit, therefore most people don’t realise they are putting themselves and others at risk by driving while over the drink drive limit.
The survey questions were:-
To the nearest ½ unit, how many units of alcohol are in the following drinks?

Commenting on the results of this survey, Hunter Abbott CEO of AlcoSense said “This is worrying for the evening, but even more worrying for the morning after as people are vastly underestimating just how much alcohol they have consumed. Only 4 of these drinks could put you over the limit the following morning. In both instances the only way to tell if the alcohol has left your system is to use an accurate personal breathalyser like AlcoSense”.

Katie Shephard, fund raising manager at BRAKE, the national road safety charity, said “Nearly one in six of all deaths on the road involve drivers who are over the legal limit. Most people don’t even consider after a night of moderate drinking they may still be over the limit to drive, well into the next day. Because everyone is different you cannot guess when the alcohol has passed from your system the morning after. A great way to tell is to use an accurate personal breathalyser like AlcoSense.
The breathalyser is about the size of a mobile phone and is available from Rowland Pharmacies, Maplin Electronics or AlcoSense direct. Prices start from £34.99 for the Lite and £59.99 for the Elite model.
