Why is it necessary to have regulations regarding ambulance designs?

Regulations are a means of establishing a foundation for public trust. The majority of people calling 9-1-1 for an ambulance will only do so once in their life. It is an unplanned event where a caller reaches out for help with an expectation that those who respond are appropriately educated and equipped to assist in a safe and efficient manner. There has been considerable research conducted within the past decade that has resulted in standards that make the ambulance environment safer. Regulations should be reviewed and revised to maintain contemporary standards.
