drinks

drinks_to_reach_permille

How many servings of a drink bring a person to a given blood alcohol level (e.g. "how many beers are 0.5 permille"), as a range: the low end assumes a 10 % resorption deficit and slow elimination, the high end 30 % and fast elimination. With hours_of_drinking > 0 the drinks are spread over that time and the level is the one reached at its end. Drink: an id from list_drinks, or ml + vol. Answers a question about amounts, never about whether driving is safe.

list_drinks

Typical German drink servings with volume, alcohol by volume and grams of pure alcohol. Use the ids in estimate_blood_alcohol.

convert

convert_breath_blood_alcohol

Convert breath alcohol (mg/l, what a roadside breathalyser measures) to blood alcohol (permille) or back, at the German legal ratio 1:2000 (0.25 mg/l = 0.5 permille). Give exactly one of breath_mg_per_l or blood_permille. The individual ratio varies, so the result is the legal equivalent, not a measurement.

drink

drink_driving_limits_europe

Blood alcohol limits for car drivers in 25 European countries, with the stricter limits for novice, young or professional drivers. Optional country: ISO code (AT, IT, GB-ENG, GB-SCT …) or German or English name; without it, all countries. Country names and notes in German.

estimate

estimate_blood_alcohol

Estimate blood alcohol concentration in permille (g/kg, the German unit; 0.5 permille = 0.05 % BAC) from body data and drinks, using Widmark with Watson body water, a 10-30 % resorption deficit and 0.1-0.2 permille/h elimination. Returns the peak and current value as a range and conservative hours until below 0.5, 0.3 and 0.0 permille. Drinks: either an id from list_drinks or ml + vol (percent ABV).

german

german_drink_driving_limits

The blood alcohol limits in German road traffic (0.0, 0.3, 0.5, 1.1, 1.6 permille): who they apply to and the legal consequences (fines, points, driving bans, criminal offence). Text in German.
