Car insurance became mandatory in the United States as a result of state laws and regulations. The first state to require car insurance was Connecticut in 1925. The purpose of mandatory car insurance is to ensure that drivers have financial protection in case of accidents or damages. The specific requirements for car insurance vary by state, but most states require drivers to have liability insurance, which covers damages to other people or property in an accident caused by the insured driver. Some states also require additional coverage, such as personal injury protection or uninsured/underinsured motorist coverage. The implementation of mandatory car insurance has helped to ensure that drivers are financially responsible for their actions on the road and has provided a way for accident victims to seek compensation for their losses.
