Can the consumption of amphetamines increase the driver's tendency of risky and aggressive behaviour?

In the photo you can see a plastic bag with white powder and several capsules - an image associated with drugs, including amphetamine. Amphetamine is a stimulant: it gives a boost of energy and a false sense of self-confidence and strength, so the driver makes risky decisions, drives faster and reacts aggressively to other road users. The answer is: yes.

The Road Traffic Act prohibits a person who is intoxicated, after drinking alcohol or after using a substance that acts similarly to alcohol from driving a vehicle; amphetamine is one of these substances, and driving under its influence is a crime. After taking amphetamine, a person overestimates their abilities, does not feel tiredness, has a narrowed focus of attention and a tendency towards impulsive, reckless manoeuvres, and when the effect wears off, sudden exhaustion follows. Any psychoactive substance rules out getting behind the wheel - not only on the day you take it.

Legal basis: Art. 45 para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym); Art. 178a of the Criminal Code
