Final answer:
The driver is responsible for making sure that all passengers, particularly those under 18, are properly restrained, with specific restraint types for different age groups of children.
Step-by-step explanation:
The driver is typically responsible for ensuring that passengers are properly restrained until they reach the age of 18. This age can vary slightly depending on the state or country laws. Generally, for children ages 0 to 2.5, car seats are required; for children ages 2.5 to 6, booster seats are common; and beyond that age, seat belts are the standard until they become adults. It is essential for the driver to ensure that all child and adolescent passengers follow the appropriate safety protocols to prevent injuries during a vehicle impact, as highlighted by safety measures such as airbag deployment upon impact. This not only protects individuals but also society at large from bearing the costs and consequences of accidents.
