What should be noted when using the prop stand?

Your answer is correct as it includes all necessary aspects regarding the use of the prop stand on a motorbike.

1. Avoiding parking on a slope is essential because it can lead to the motorcycle tipping over, which poses a safety risk and may cause damage.
2. Fully extending the prop stand ensures that the motorcycle is securely supported, reducing the risk of it falling over when parked.
3. The prop stand switch is an important safety feature that prevents the motorcycle from being driven off with the stand still extended, which could lead to accidents.

Understanding and applying all three points is crucial for safe motorcycle operation and parking as outlined in German traffic regulations. Each of these aspects contributes to rider safety and the prevention of accidents.
