Italy just passed a law that requires the use of alarms that would notify parents if a child is left in a car seat.

The law in an effort to prevent deaths of infants and children forgotten in hot cars.

"The devices must emit audio and visual signals that can been perceived both inside and outside the vehicle and that are triggered if the child in the car seat is left behind. The requirement applies to car seats for children younger than 4," says WIVB.
