Driving any vehicle under the influence of alcohol or drugs is totally prohibited. Despite it being common knowledge that alcohol and driving are not compatible, even today many fatal accidents have their main cause in alcohol consumption. According to the General Directorate of Traffic (DGT), “alcohol is present in between 30% and 50% of fatal accidents.” It can be believed that the risk of alcohol altering our abilities is only possible in very high consumption. While it is true that the more alcohol you consume, the greater the risk, any amount of alcohol in the blood will cause changes in the body and a greater chance of suffering a collision.

As the DGT warns, “the only really safe rate is 0.0g/l.” Current legislation allows a blood alcohol level for drivers in general of 0.5 g/l in blood or 0.25 mg/l in breath and 0.3 g/l in blood for novices and professionals or 0.15g /l in expired air. Alcohol consumption alters our perception of road hazards and its effects depend on the amount ingested and the individual’s weight.
