You want to carry a child in your car. When must you use a child seat for this purpose?

You answered correctly. In Germany, a child seat is mandatory when transporting children who are younger than 12 years old and shorter than 150 centimeters. Both conditions must be fulfilled—meaning, if a child is under 12 and also below 150 cm in height, a child seat must be used for their safety. Once the child turns 12 or exceeds 150 cm in height, they may use a regular seatbelt without a special child seat. This rule helps protect children with appropriate restraint systems suited to their age and size. Knowing this ensures you always follow the law and keep young passengers safe.
