This sign indicates a steep road gradient of 15%, demanding careful speed adjustment and anticipation of reduced braking effectiveness. Reviewing this road sign meaning is crucial for your German driving theory test preparation and safe driving.
German road sign 110-15, officially designated "Steigung 15%", belongs to the danger warning signs group. It warns about a road-layout, clearance, weather, or surface condition that can reduce control, sight distance, grip, or available space before the driver reaches the hazard. You may see it in approaches to hazards, rural roads, urban conflict points, railway crossings, roadworks, and weather-sensitive sections, depending on how the road authority has arranged the location. The practical meaning is not just the symbol itself, but the driving decision it triggers: adjust speed, position, priority, route choice, stopping behaviour, or attention before the situation becomes urgent. For learners, the key skill is anticipating what could go wrong before the hazard is visible. Always combine the sign with road markings, traffic lights, police instructions, and any supplementary plates at the same location.
German road sign 110-15 means "Ascent 15%" and is officially listed as "Steigung 15%". In practice, it tells drivers to recognise the situation early, adapt before reaching the controlled area, and check whether markings or supplementary plates change how the rule applies.

This FAQ strengthens your understanding and supports accurate decision making for the German driving theory exam in Germany.
Sign 110-15 warns you of a steep 15% uphill gradient. This means your vehicle will lose speed more quickly, and engine power will be reduced. You should prepare to change to a lower gear to maintain momentum and control, and reduce your speed before you start the ascent.
You'll commonly encounter this danger warning sign on approaches to steep uphill sections of road. This can be on rural roads, mountainous areas, or even on certain urban or suburban routes where significant inclines exist. It's placed well in advance to give you time to react.
A common mistake is not reacting early enough. Learners might continue at their current speed until they are already on the incline, leading to a loss of speed and potentially struggling to maintain control. Another error is forgetting to downshift, which can strain the engine and reduce acceleration.
No, the 110-15 sign does not require you to stop. It is a warning sign indicating a change in road gradient. Your reaction should be to reduce speed and select an appropriate gear to safely manage the steep ascent.
While the primary effect of a steep ascent is on your vehicle's speed and acceleration, it's also important to consider braking. Descending a steep hill after climbing it (which this sign doesn't directly warn about, but is related) requires careful use of engine braking and brakes. For the ascent itself, maintain a safe speed so you are in control and can brake if necessary for traffic ahead.
