This group of signs, primarily from category A in Germany, is crucial for your driving education. They alert you to potential dangers on the road, such as sharp curves, unexpected crossings, or adverse conditions. Recognizing and understanding these signs allows you to adjust your speed and driving position proactively, ensuring your safety and the safety of others. Mastering these warnings is a key step in both passing your theory exam and becoming a confident, responsible driver.
An explanation of how German Danger Warning Signs road signs apply in real traffic situations in Germany. Learn where these signs are typically placed, what drivers are expected to do when they appear, and how correct reactions help you stay safe, avoid fines, and succeed in your German driving theory exam.
German danger warning signs (Category A) are ubiquitous across all types of roads, from busy urban streets to rural country lanes and highways. You'll encounter them well in advance of the hazard they signify, giving you time to prepare. For instance, signs for curves (like 103-10 for a left curve or 103-20 for a right curve) prepare you for changes in direction, prompting you to reduce speed and position your vehicle correctly. Signs indicating intersections (102) or side roads require heightened awareness of potential cross-traffic. Warnings about gradients, such as descents (e.g., 108-10 for a 10% downhill slope) or ascents (e.g., 110-10 for a 10% uphill slope), inform you about changes in speed potential and the need for gear selection. You'll also see signs for specific risks like slippery roads (114), falling rocks (101-15 or 101-25), wild animals (142-10 or 142-20), or children (136-10 or 136-20), all of which demand a significant adjustment in your driving behaviour, often involving reduced speed and increased observation.

Clear answers to common questions about the German Danger Warning Signs road sign category. Use this FAQ to review tricky rules, understand how these signs appear in exam scenarios, and remove confusion that often leads to mistakes in the German driving theory exam in Germany.
The primary purpose of German danger warning signs is to alert drivers to potential hazards ahead on the road. These signs inform you about risks that require you to adjust your speed, change your road position, or pay extra attention to your surroundings. By providing advance notice, they help prevent accidents and ensure smoother traffic flow.
Most danger warning signs indicate a general risk that begins at or shortly after the sign's location, or covers a certain stretch of road. For example, a curve sign warns you about the upcoming curve, and you should adjust your speed before entering it. Signs for things like slippery roads or falling rocks often indicate a specific area where that hazard is prevalent.
These signs indicate that the hazard is located on the right side (e.g., 101-10 for aircraft operations on the right) or the left side (e.g., 101-20 for aircraft operations on the left) of the road or adjacent to it. This specificity is important for understanding the exact nature and location of the potential danger, allowing you to react accordingly. For instance, an aircraft warning on the left might affect your visibility or create noise, while on the right, it might be more about a physical obstruction or proximity.
When you see a sign for a steep descent (like 108-10 for a 10% slope) or ascent (like 110-10 for a 10% slope), it signals a significant change in road gradient. For descents, you should select a lower gear to control your speed using engine braking and avoid overheating your brakes. For ascents, be prepared for a potential loss of speed, especially if you are on a heavier vehicle or pulling a trailer, and ensure you have enough momentum. Always adjust your speed appropriately before entering the gradient.
Seeing signs like 'Wild animals' (142-10/20) or 'Pedestrians' (133-10/20, 136-10/20) means you must be extra vigilant. For animal warnings, be prepared for animals to suddenly enter the road, especially at dawn and dusk. Reduce your speed and scan the roadside. For pedestrian warnings, be aware that pedestrians may be present, possibly including children, and be ready to stop if necessary. Maintain a safe distance and be ready to brake.
