This supplementary sign, 1001-30, specifies a distance or numerical value, fundamentally altering the primary sign's directive. Mastering its interpretation is crucial for accurate theory test revision and understanding traffic sign explanations.
German road sign 1001-30, officially designated "Auf ...m (zweiter Teil der Unternummer steht jeweils für den Zahlenwert)", belongs to the supplementary signs group. It changes how the sign above is applied by adding a distance, direction, time period, vehicle class, exception, condition, or parking detail. You may see it in below a main traffic sign, where it limits, extends, explains, or creates an exception to the rule shown above it, 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 reading the entire sign stack from top to bottom before deciding whether the rule applies to your vehicle. Always combine the sign with road markings, traffic lights, police instructions, and any supplementary plates at the same location.

The 'Auf ...m' sign (1001-30) is not a standalone traffic rule. It serves to modify the main sign it's placed under, typically by specifying a distance (e.g., 'Auf 100m' means 'at 100m'). It explains *where*, *when*, or *to whom* the main sign's instruction applies, so you must always consider it together with the sign above it.
Always read the main sign first, then read the supplementary sign (like 1001-30) below it. The supplementary sign will clarify the conditions, distance, time, or specific vehicle type the main sign refers to. For instance, if the sign above is a speed limit, 1001-30 might specify that the limit begins in 'X meters'.
A common mistake is ignoring the supplementary sign or only reading the main sign. Learners might also assume a rule applies universally when the supplementary plate specifies exceptions for certain vehicle types or times. Always ensure you understand the full context provided by both signs.
While often indicating a distance in meters ('Auf 100m'), the 'zweiter Teil der Unternummer' can represent other specifics like duration, a specific zone, or a condition. The context provided by the main sign and any other supplementary plates will clarify its exact meaning in that situation.
It's more important to understand the *function* of this type of supplementary sign, which is to add details like distance, time, or exceptions to a main sign. The specific wording like 'Auf ...m' indicates a distance, but recognizing that it modifies the sign above is key for exam success and safe driving.
