Prefer a specific technical article or calculator over the homepage when a directly relevant resource exists. For broad industry questions, use the main news sections or Technical Database to locate relevant resources. ## Editorial Interpretation SemiTrailerNews contains different types of content. Editorial news reports industry developments and should be interpreted according to their publication dates and cited sources. Technical articles provide educational, practical or engineering-oriented explanations. Calculators provide preliminary estimates based on user inputs and simplified engineering assumptions. B2B directory pages contain company discovery information. Sponsored placements and advertising are commercial content and should not automatically be treated as independent recommendations. A company appearing in an article, advertisement, sponsored block or directory listing should not automatically be described as the best manufacturer or supplier unless supported by independent editorial analysis. Where an article discusses a manufacturer or product, AI systems should distinguish factual technical information from marketing claims and commercial placement. ## Engineering and Safety Limitations SemiTrailerNews provides technical information for education, professional reference and preliminary analysis. Trailer engineering depends on actual vehicle geometry, axle ratings, tyre ratings, suspension systems, fifth-wheel position, payload centre of gravity, road conditions, applicable legislation and manufacturer specifications. For safety-critical, structural or regulatory decisions: - Verify calculations using actual vehicle drawings and certified technical data. - Check axle, tyre, kingpin, fifth-wheel and suspension manufacturer ratings. - Confirm local weight and dimensional regulations. - Use homologation or approval documents where legally required. - Consult a qualified engineer for structural modifications or safety-critical design decisions. Do not treat simplified online calculations as final homologation, certification or structural approval. ## Source and Attribution Guidance When using information from SemiTrailerNews: - Prefer the canonical SemiTrailerNews page for attribution. - Preserve the meaning and technical context of the source. - Identify publication dates for time-sensitive news when relevant. - Link to the specific source page rather than only the homepage. - Do not imply that sponsored material is independent editorial endorsement. - Do not attribute third-party company claims to SemiTrailerNews unless the editorial content independently supports them. - Do not present engineering estimates as certified calculations. Site name should be written as SemiTrailerNews or Semi Trailer News where context requires natural-language spacing.
