Legal Requirements for Child Seats in Turkey\n\nUnder the Turkish Highway Traffic Regulation (Karayolları Trafik Yönetmeliği), child restraint systems (çocuk bağlama sistemleri) are mandatory for young passengers. The law specifies that children who are under 150 centimeters in height and weigh less than 36 kilograms must be transported in an approved child safety seat appropriate for their size. \n\nOnce a child exceeds 150 cm in height, they are permitted to use standard vehicle seat belts, provided they sit in the rear seat. For children between 135 cm and 150 cm, adult seat belts may be used, but only if they are seated in the rear of the vehicle. These strict physical thresholds prevent seat belts from causing severe neck or abdominal injuries during a collision.\n\n## Classifications of Child Restraint Systems\n\nChild safety seats are categorized into distinct groups based on the weight of the child to ensure maximum effectiveness. During your driving theory preparation, it is useful to understand these general groups:\n\n* Group 0 and 0+: Designed for infants weighing up to 13 kg (approx. 0 to 12 months). These are always installed in a rear-facing position.\n* Group 1: Suitable for toddlers weighing between 9 kg and 18 kg (approx. 9 months to 4 years).\n* Group 2: Booster seats designed for children weighing 15 kg to 25 kg (approx. 3 to 7 years).\n* Group 3: Booster cushions for older children weighing 22 kg to 36 kg (approx. 6 to 12 years) to ensure the vehicle's standard three-point seat belt fits correctly across the pelvis and shoulder.\n\nHistorically, vehicle safety pioneers like Volvo developed the first rear-facing child seats in 1964 and booster cushions in 1978, establishing the safety standards that modern Turkish road laws rely on today to protect young occupants.\n\n## Airbag Hazards and Rear-Facing Seats\n\nOne of the most frequent safety questions on the Turkish driving theory exam (ehliyet sınavı) concerns the placement of rear-facing infant seats relative to vehicle airbags. \n\nIf you place a rear-facing infant carrier on the front passenger seat, you must deactivate the front passenger airbag. If the airbag remains active, a deployment during an accident will strike the back of the child seat with explosive force, causing fatal head and neck trauma. The safest location for any child seat is always the rear middle or rear passenger side seats.\n\n## Exam Tips and Driver Responsibility\n\nIn Turkish driving theory, the driver bears absolute legal, civil, and moral responsibility for the safety of all passengers. If a child is transported without a proper safety seat, the driver will face administrative fines and penalty points on their license. On the MTSK e-sınav, look out for questions testing the exact height limit (150 cm), weight limit (36 kg), and the driver's duty of care.
