What must you take into consideration when selecting your speed?

You answered correctly. When choosing your speed, German traffic rules require you to always consider visibility, weather, the condition of the road, traffic flow, and your own driving ability. For example, if visibility is poor due to fog or if the road is wet or slippery, you must reduce your speed, even if a higher speed limit is posted. Additionally, you should not drive faster than you can safely control your vehicle based on your skills and experience. This helps prevent accidents and keeps all road users safe. Always adjust your speed to match the current situation, not just the posted speed limit.
