# The beers or wines I can drink so as not to give a positive breathalyzer test

## While it is ideal not to take a drop before touching a steering wheel, Spanish law sets the limit at 0.5 grams per liter of blood, except for novice or professional drivers where the speed drops to 0.3

At Christmas, between company dinners and family meals, there are many who drink and then decide to get behind the wheel of the car. And while it is ideal not to take
not a drop before you get into a vehicle with the intention of driving, Spanish law sets the limit at 0.5 grams per liter of blood (or 0.25 mg/l of exhaled air), except for novice or professional drivers where the speed drops to 0.3 (0. 15). And be careful because it will put a lot of checks on these dates.

For this purpose, the DGT has drawn up a table in which a number of equivalences are broken down. Keep in mind that it is only indicative, it depends on the weight and constitution of the person and should always be taken lightly: if you are close to the limit with two beers, it is better that you drink only one.

We also need to consider the blood alcohol curve, which is based on the fact that alcohol can be detected in the blood 5 minutes after ingestion and reaches its maximum level between 30 and 90 minutes afterwards.

Specifically, the pure alcohol consumed is calculated by multiplying the strength of the drink used (a number followed by the zero degrees (º) indicated on the label of the drink) by the amount ingested (in cubic centimeters or milliliters and by 0. 8 – Density of alcohol – divided by 100. The alcohol degree is thus calculated by dividing the amount of pure alcohol ingested by the weight (in kilograms) of the drinker multiplied by 0.7 (0.6 in women who are less able to tolerate alcohol ).

The effects appear from the first moment, even at rates lower than allowed to drive. So from 0.3 to 0.5 – it is reached with 2 beers or two wines – the reaction time already increases, coordination problems begin and the speed is underestimated. At more than 0.5 gr/l. of alcoholemia, vision problems starting and above 0.8, severe attention and coordination problems and strong drowsiness.

From 1.2 g/l blood alcohol (0.6 in breath), driving is considered a crime, punishable by imprisonment of 3 to 6 months.
