Get clear, practical answers to the most common questions about the 108-10 - Descent 10% road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the German driving theory exam in Germany.

What does the 'Descent 10%' (108-10) road sign mean?

The 'Descent 10%' road sign (108-10), officially 'Gefälle 10%', is a warning sign indicating a steep downward slope on the road. The '10%' specifies the gradient, meaning for every 100 metres travelled horizontally, the road drops by 10 metres. It's a crucial alert to adjust your driving before encountering the steep section.

How should I react when I see the 'Descent 10%' (108-10) sign?

Upon seeing the 'Descent 10%' sign, you should proactively reduce your speed and select an appropriate lower gear to control your descent without excessive braking. This also helps prevent overheating your brakes on long descents. Always be aware of your surroundings and any other traffic.

Are there any specific things to watch out for with this sign in a theory test?

Yes, theory tests often focus on anticipating hazards. For the 'Descent 10%' sign, common traps include testing your understanding that you must prepare *before* the descent, not when you're already on it. Examiners also check if you know how to manage your speed and braking safely to maintain control.

Can supplementary signs change the meaning of the 'Descent 10%' (108-10) sign?

Absolutely. Always look for additional plates placed with the 'Descent 10%' sign. These might specify the length of the steep section, indicate specific hazards within the descent (like sharp bends), or provide other crucial information that modifies how you should behave. The sign itself is a general warning, and supplementary plates provide context.

Why is a 10% descent considered dangerous enough to warrant a warning sign?

A 10% gradient is quite steep and can significantly affect your vehicle's behaviour. It increases your speed due to gravity, making it harder to stop quickly if needed. It can also lead to brake fade if used excessively. The sign ensures drivers are aware and prepared, reducing the risk of accidents.
