A turntable ladder (TL) is an aerial apparatus with a large ladder mounted on a pivot which resembles a [[turntable]], giving it its name. The key functions of a turntable ladder are allowing access or egress of firefighters and fire victims at height, providing a high-level water point for firefighting (elevated master stream), and providing a platform from which tasks such as ventilation or overhaul can be executed.

To increase its length and reach, the ladder is often [[telescoping (mechanics)|telescoping]]. Modern telescopic ladders may be [[hydraulic]] or [[pneumatic]]. These mechanical features allow the use of ladders which are longer, sturdier, and more stable. They may also have pre-attached hoses or other equipment.

The pivot can be mounted at the rear of the chassis or in the middle, just behind the cab. The latter is sometimes called a "mid-ship" arrangement, and it allows a lower travel height for the truck.

While the traditional characteristic of a TL was a lack of water pumping or storage, many modern TLs have a water pumping function built in (and some have their own on-board supply reservoir). Some may have piping along the ladder to supply water to firefighters at the top of the ladder, and some of these may also have a [[fire monitor|monitor]] installed at the top. Other appliances may simply have a track-way to securely hold a manually-run hose reel.
