Question 5357
Does alcohol impair our ability to correctly perceive lights and traffic signals?
- Yes, because we perceive lights and signals less clearly, especially when they are red.
- Only in the case of lights, but not signals.
- No, if we have had only a little to drink and do not reach the maximum permitted limit.
Show answer and explanation
Correct answer: Yes, because we perceive lights and signals less clearly, especially when they are red.
Yes. Alcohol makes it harder to perceive lights and signs, especially red ones, such as a red traffic light or the blurry stop sign in the picture. This starts at around 0.2 g/l in blood, below the legal limit, so drinking only a little does not spare you.
