DGT rules in English
Drink driving and driver condition rules in Spain
These rules identify when a question is really about impairment, fatigue, or distraction.
Alcohol questions reward zero-risk thinking
Any alcohol worsens your driving. The only safe amount is none.
Watch for: The question mentions alcohol, drink-driving, or blood or breath alcohol.
Alcohol effects depend on body and timing
The same amount of alcohol can affect different people very differently.
Watch for: The question asks why two people react differently to the same amount of alcohol.
Drugs and medicines are impairment cues
Any drug or medicine that affects your concentration or reactions is a driving risk — even if it is prescribed.
Watch for: The question mentions medication, drugs, side effects, or a medicine leaflet.
Fatigue gets worse before you admit it
Tiredness slows your reactions and affects your judgement. The only fix is rest.
Watch for: The question mentions tiredness, sleep, long trips, night driving, or microsleeps.
Distraction steals distance
Any distraction — phone, food, or just thinking about something else — uses up the distance you need to react.
Watch for: The question mentions a phone, GPS, eating, or looking away while driving.
