Final answer:
Never place a rear-facing infant seat in the front seat if the car has airbags, as they can cause harm to the child when deployed.
Step-by-step explanation:
You should never place a rear-facing infant seat in the front seat if the car has airbags. Airbags are designed to deploy upon impact to minimize serious injuries to passengers. They do this by allowing the net force on occupants to act over a much longer time during a sudden stop, which reduces the force felt by passengers.
For an infant in a rear-facing seat placed in the front, the deployment of an airbag can be dangerous because the force of the airbag could be directed at the back of the infant seat, potentially causing harm to the child. Instead, rear-facing infant seats should be placed in the rear seats of the vehicle where they're away from the impact of front airbags and better protected during a collision.
