What do you have to expect after these traffic signs?

This traffic sign warns drivers about a continuous downhill slope that extends for 800 meters. The triangular sign with a downward-sloping black triangle and a percentage (10%) indicates the steepness of the descent. The additional plate below with "800 m" and arrows shows the length of this slope.

In German traffic rules, this combination means you should expect a downhill slope of 10% gradient lasting for 800 meters. It's important to adjust your driving accordingly by controlling your speed and using engine braking to avoid overheating the brakes.

This sign does not indicate the beginning of a slope further ahead or an uphill slope. It directly informs about the current section of road where the downhill slope extends.
