Are children required to use booster seats in Italy?

In Italy, the law mandates that children under a specific height must be secured in appropriate child restraint systems, such as booster seats. This requirement is rooted in safety regulations designed to protect young passengers by ensuring they are seated in a manner that reduces the risk of injury during a crash. The law emphasizes not just age but height, acknowledging that physical size is a critical factor in determining the effectiveness of seat belts and other restraints.

Children must use booster seats until they reach a height of 135 centimeters (approximately 4 feet 5 inches). This ensures that the vehicle’s seat belt fits properly and provides adequate protection. Thus, the correct option affirms the importance of adhering to these safety measures to ensure children's safety while traveling in vehicles. In contrast, the other options either overlook the legal requirement, specify incorrect age limits, or misinterpret the context of using booster seats only for certain situations like long journeys.
