Most shopping carts now have a printed weight limit to increase safety measures against improper use. The weight limit of a shopping cart declares the amount of heavy load a cart can safely hold without tipping over or falling apart. A baby's car seat is often too heavy by itself to be carried by a shopping cart. The combination of a baby car seat and the baby can be dangerous for the grocery cart's weight limit. Grocery carts carrying this heavyweight cannot often predict hazardous situations such as bumps on the road and swift turns around the aisles.
