A Child Restraint System (CRS) is a safety device designed to protect young passengers in vehicles. It includes various types of seats, such as infant seats, convertible seats, and booster seats, which are specifically designed to accommodate children of different ages and sizes. Proper use of a CRS can significantly reduce the risk of injury during a car accident. CRS must be installed correctly and used according to the manufacturer's guidelines to ensure maximum safety. Many countries have laws requiring the use of a CRS for children, emphasizing its importance in promoting child safety while traveling in vehicles.
