A weighbridge is a very large set of scales built flat into the ground, big enough for a lorry to drive right onto so the whole vehicle and its load can be weighed at once. You see them at quarries, ports, waste sites, grain stores, recycling plants, and at the entrance to factories that buy or sell things by weight. The way it works matters for understanding the word: the truck is weighed full, then weighed again empty, and the difference is what was carried. That second weighing is called the tare, and the pair of readings is how a whole industry buys and sells sand, scrap metal, rice, or rubbish. It also has a legal side — many countries require trucks to use a weighbridge to prove they are not over the road limit, and roadside checks send drivers to one. This is a mainly British and Commonwealth word; American English usually says **truck scale**, and the roadside checking place is a **weigh station**. It is a plain, practical, non-formal noun — a driver or a site worker says it all day. It has a regular plural, weighbridges, and it is often used before another noun: weighbridge ticket, weighbridge operator, weighbridge office. If you read logistics or shipping documents in Taiwan, `weighbridge ticket` is likely the phrase you will meet, meaning the printed slip that records the weight.
