  1. Which of the following substances makes it illegal to drive in Germany if detected above a legal threshold?

    Answer: Cannabis (THC)

    Driving under the influence of cannabis (THC) above the legal threshold is prohibited in Germany, with a limit of 3.5 ng/ml in blood serum following the 2024 reform.

  2. Following Germany's 2024 cannabis law reform, what is the THC blood serum limit for drivers?

    Answer: 3.5 ng/ml

    Following the 2024 cannabis reform, Germany set the THC limit for driving at 3.5 ng/ml in blood serum — similar in principle to the BAC system for alcohol.

  3. How does fatigue (Müdigkeit) affect a driver's ability compared to alcohol intoxication?

    Answer: Fatigue causes effects similar to alcohol, including impaired judgment and slower reactions

    Fatigue impairs driving similarly to alcohol — it slows reactions, reduces concentration, and can cause involuntary microsleep episodes.

  4. What is 'Sekundenschlaf' (microsleep) and why is it dangerous while driving?

    Answer: Brief involuntary sleep episodes lasting 1–30 seconds that cause complete loss of vehicle control

    Sekundenschlaf (microsleep) refers to brief involuntary sleep episodes of 1–30 seconds during which the driver has absolutely no awareness or control of the vehicle.

  5. What effect should drivers be aware of when taking antihistamine medication before driving?

    Answer: They can cause significant drowsiness and impair driving ability

    Many antihistamines cause drowsiness as a side effect, which can significantly impair reaction time and driving ability — the medication label typically warns against operating machinery.

  6. What typically happens when a driver combines alcohol with prescription sedatives or painkillers?

    Answer: The combined effect is often stronger and more dangerous than either substance alone

    Combining alcohol with sedatives or painkillers typically produces a synergistic effect — the combined impairment is far greater and more dangerous than either substance would cause independently.

  7. What is the most effective action to take when feeling fatigued during a long drive?

    Answer: Stop at a rest area and sleep for at least 20 minutes

    The only truly effective remedy for driving fatigue is to stop and rest — a sleep break of at least 20 minutes significantly restores alertness; stimulants provide only temporary relief.
