What are the possible effects of hashish consumption?

The selected combination is correct because all three effects are significant consequences of hashish consumption that can impair a driver's ability to operate a vehicle safely.

1. Diminished awareness of danger refers to the reduced ability to recognize potential hazards on the road, leading to increased risks during driving.
2. Increased likelihood of mistakes in assimilating information means that a driver may struggle to interpret traffic signals, signs, and other critical information, which can contribute to dangerous situations.
3. Misjudgment of speed and distance can lead to poor decision-making regarding stopping distances and passing maneuvers, greatly increasing the risk of accidents.

According to German traffic laws, driving under the influence of drugs like hashish is prohibited due to these impairments, as they can significantly increase the likelihood of accidents and endanger both the driver and other road users. It is essential to recognize the impact of all these effects to understand the full scope of danger involved when operating a vehicle after consuming substances that impair cognitive and motor functions.
