German road sign 1052-31, meaning "Only Vehicles with Hazardous Cargo", is a supplementary sign. It modifies the primary sign above it, indicating restrictions or conditions specifically for vehicles carrying substances that could contaminate water. Drivers must always check if this sign applies to their vehicle and adapt their behaviour or route before entering the controlled area.
This supplementary sign, 'Nur Fahrzeuge mit wassergefährdender Ladung,' specifically restricts access for vehicles carrying hazardous materials. Mastering its meaning is vital for correct theory test revision and safe driving in Germany.
German road sign 1052-31, officially designated "Nur Fahrzeuge mit wassergefährdender Ladung", 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. An end version marks the point where that specific rule, facility, or marked section ceases to apply. 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.
German road sign 1052-31 means "Nur Fahrzeuge with wassergefährdender Ladung" and is officially listed as "Nur Fahrzeuge mit wassergefährdender Ladung".

This sign, 1052-31, means "Only Vehicles with Hazardous Cargo". It is always used with a main sign above it and restricts the main sign's rule to only apply to vehicles carrying substances that could pollute water. You must check if your vehicle falls into this category before proceeding.
You must carefully read the main sign above sign 1052-31 first. Then, consider the meaning of 1052-31. If your vehicle is transporting goods that are considered water-polluting, then the rule indicated by the main sign applies to you. If your vehicle is not carrying such cargo, the main sign's restriction or information does not apply to you.
A common trap is failing to read the main sign above the supplementary plate. Learners might only focus on the "water-hazardous cargo" text and not understand the actual restriction or information being conveyed. Always interpret the entire sign stack from top to bottom to grasp the full context.
Not necessarily. Sign 1052-31 itself doesn't mean 'stop'. It specifies that the action or restriction dictated by the main sign above it *only* applies to vehicles carrying water-endangering loads. For instance, if the main sign indicates a speed limit, that limit only applies to hazardous cargo vehicles. If your vehicle doesn't carry such cargo, you are unaffected by that specific speed limit.
You'll often see this sign near sensitive areas like water protection zones, rivers, lakes, or reservoirs. It's a measure to reduce risks in case of an accident, preventing spills that could contaminate important water sources. Always be extra vigilant when driving in such environmentally sensitive locations.
