A ladder truck is a common term for a firefighting vehicle that is equipped with a long ladder, often made of steel, that can be raised and extended to reach high places. However, there are a number of other terms that can be used to describe this type of vehicle, depending on the region or country. In the United Kingdom, for example, it may be referred to as an aerial ladder platform or an aerial appliance, while in Australia and New Zealand it is often known as an aerial appliance or a hydraulic platform. Other synonyms include rescue truck or tower ladder, depending on the specific features and capabilities of the vehicle.
