German road sign 1010-51 is a supplementary sign that modifies the meaning of the main traffic sign it's attached to. Specifically, it indicates that the main sign's rule applies only to motor vehicles exceeding a permissible gross mass of 3.5 tonnes, including their trailers, and to tractors. However, it explicitly exempts passenger cars and buses. Always read this sign in conjunction with the primary sign above it to understand the complete traffic regulation and how it affects your driving decisions, especially for the theory exam.
This supplementary sign clarifies restrictions for vehicles exceeding 3.5 tonnes, excluding passenger cars and buses. Mastering its meaning is crucial for understanding traffic sign explanations and preparing for your German theory test on road sign interpretation.
German road sign 1010-51, officially designated "Kraftfahrzeuge mit einer zulässigen Gesamtmasse über 3,5 t, einschließlich ihrer Anhänger, und Zugmaschinen, ausgenommen Personenkraftwagen und Kraftomnibusse", 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.
German road sign 1010-51 means "Motor vehicles with zulässigen Gesamtmasse über 3,5 t, einschließlich ihrer Anhänger, Zugmaschinen, ausgenommen passenger cars buses" and is officially listed as "Kraftfahrzeuge mit einer zulässigen Gesamtmasse über 3,5 t, einschließlich ihrer Anhänger, und Zugmaschinen, ausgenommen Personenkraftwagen und Kraftomnibusse".

Get clear, practical answers to the most common questions about the 1010-51 - Motor vehicles with zulässigen Gesamtmasse über 3,5 t, einschließlich ihrer Anhänger, Zugmaschinen, ausgenommen passenger cars buses road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the German driving theory exam in Germany.
Sign 1010-51 acts as a modifier for the sign directly above it. Its purpose is to specify that the main sign's instruction or prohibition applies specifically to motor vehicles with a permissible gross mass over 3.5 tonnes, including their trailers, and to tractors, while excluding passenger cars and buses. It's crucial for understanding the exact scope of a traffic rule.
This supplementary sign explicitly exempts passenger cars (Personenkraftwagen) and buses (Kraftomnibusse) from the restriction or instruction of the main sign above it. If you are driving a car or a bus, the rule indicated by the main sign does not apply to you, even if you are within an area where it might otherwise be in effect.
A frequent trap in the theory exam is failing to read the supplementary sign in conjunction with the main sign. Learners might only focus on the primary sign and miss that the restriction is narrowed down by 1010-51 to specific vehicle types and weights, or conversely, they might assume an exemption applies to their vehicle when it doesn't. Always interpret the entire sign stack.
No, sign 1010-51 specifically states that the restriction applies to 'Motor vehicles with zulässigen Gesamtmasse über 3,5 t, einschließlich ihrer Anhänger'. This means the 3.5-tonne limit applies to the vehicle and its trailer combined. Passenger cars, even if towing a trailer, are generally excluded unless the car itself pushes the combined mass over 3.5 tonnes and it's not a bus.
If sign 1010-51 is placed above a speed limit sign, it means the reduced speed limit only applies to motor vehicles over 3.5 tonnes and tractors, excluding cars and buses. If you are driving a car or a bus, you are not subject to this specific speed limit indicated by the main sign.
