The system is designed whereas the government not only regulates and oversees system performance, but the ambulance service contractor is held accountable to meet or exceed performance requirements. These requirements include, but not limited to, time constraints. Such limits are set to ensure an ambulance arrives to life-threatening emergencies without delay. The contractors failure in fulfilling the contractual obligations can result in fines being imposed, up to and including termination of contract. The agreement and contract between government and contractor are done through a competitive bidding process. This insures that the most cost-effective provision of EMS services is guaranteed.
