You wish to take several small children home after a children's birthday party. What must you observe when using your car?

When transporting small children in a vehicle, German traffic law mandates that all children must be secured using appropriate child restraints. This requirement is in place to ensure their safety while traveling. Child restraints are designed to protect children in the event of an accident, and using them significantly reduces the risk of injury.

The relevant regulation specifies that child safety seats or boosters must be used according to the weight and height of the child. It is also important to note that the requirement for child restraints applies regardless of whether you are driving within built-up areas or on the highway.

Simply using existing safety belts is insufficient, as they are not suitable for children who do not yet meet specific size requirements. Therefore, the correct answer encompasses the necessity of using prescribed child restraints for all passengers under the age of 12, ensuring compliance with road safety laws and protecting vulnerable passengers.
