A - Airbags
Airbags - An airbag inflates immediately in an accident to create a cushion between the occupants and any hard surface. They are designed to be used with a seatbelt.
Most new cars have an airbag in the steering wheel and a passenger airbag in the dash. Side airbags can be placed in the seat or the door. Curtain airbags drop down from above the door to protect the occupants' heads. Some cars offer intelligent airbags which inflate in stages according to the severity of the accident.
A rear-facing child seat should never be placed in a passenger seat opposite an operational airbag because the force of the explosion which inflates the airbag could injure the child. This is why some cars allow you to switch off the passenger airbag.
