The sign 110-20 warns drivers about a steep uphill road section with a gradient of 20%. This means the road rises significantly, which can impact your vehicle's performance, especially for heavier loads or less powerful engines. It's crucial to recognize this early and adapt your driving to maintain control.
When you see the 'Steigung 20%' sign (110-20), you should reduce your speed early enough to maintain full control as you ascend. Consider shifting to a lower gear to prevent the engine from overheating and to have better control, especially if you need to slow down or stop on the incline. You should also increase your following distance.
Yes, you must not treat this warning as optional or wait until you are directly on the steep incline. Avoid overtaking, accelerating excessively, or following too closely, as your visibility and reaction time will be reduced. Also, do not assume the danger is limited to the exact sign location; the steepness may begin shortly after the sign.
Absolutely. Supplementary plates can provide crucial additional information, such as the length of the steep ascent or specific instructions. For example, a plate might indicate that the 20% gradient applies for a certain distance, or it might highlight additional hazards like sharp bends on the incline. Always check for and obey these supplementary signs.
A common mistake is not understanding that the warning requires proactive adaptation *before* reaching the hazard. Learners might think they only need to react once they are on the steep slope, but the test expects you to anticipate and adjust your speed and gear earlier. Failing to prepare for the incline adequately can lead to loss of control or being caught out by slower traffic.
