You should refrain from driving any vehicle if you are experiencing what physical symptoms?

The combination of symptoms you indicated is correct because, according to German traffic regulations, drivers must ensure they are fit to drive. Experiencing nausea, dizziness, and fever can impair your ability to operate a vehicle safely.

Driving under these conditions can lead to decreased reaction times, impaired judgment, or even loss of consciousness, all of which pose serious risks not only to the driver but also to other road users.

German traffic law emphasizes driver responsibility, meaning if you are unwell in any significant way, it is advisable to refrain from driving. Always prioritize safety and the well-being of everyone on the road.
