Along with a blown head gasket or an engine block seizure, a broken timing belt sounds like worries and costly repairs. So to avoid this to happen, unless your vehicle has a camchain (which you never need replaceing), make sure to check and replace your cambelt/timing belt in due time.
Unless your car is a vintage model, the engine most likely has a serpentine belt drive.
On many engines, a serpentine belt powers several accessories such as the air conditioner compressor, water and power steering pumps, fan, and even the booster for the braking system.
It's definitely worth having the serpentine drive belt system checked periodically. If it fails, the engine will overheat, and worse, the car won't run.
The situation could leave you stranded on a highway or busy metropolitan street waiting for a costly tow to a local repair shop.
Listen for signs of impending belt failure. A squealing noise when the car accelerates means the belt is slipping and is not efficiently turning the drive accessories. The belt tensioner also could be worn and in need of immediate replacement.
Look for excessive cracks in the belt’s V-ribs, and chunks that have broken off the ribs.
However, visual appearance is not a reliable indicator of the expected service life of a belt. It is recommended to replace the serpentine belt every four years.

"A serpentine belt, also known as a multi-vee, poly-v, or multi-rib belt, is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc."
"Definition: A type of flat rubber drive belt that is used to turn multiple accessories on the front of an engine. It is called a serpentine belt because of the way it snakes around the various pulleys. Many vehicles now have a single serpentine drive belt because it eliminates the need for several separate V-belts. A spring-loaded pulley maintains tension on the serpentine belt. This does away with the need to retension the belt when it is replaced. Serpentine belts generally last 25% to 50% longer than conventional V-belts."
