Motor vehicles, in the USA and many other countries, is designed to cover risk of financial liability or the loss of a motor vehicle the owner may face if their vehicle is involved in a collision resulting in property or physical damages. Most states require a motor vehicle owner to carry some minimum level of liability insurance. States that do not require the vehicle owner to carry car insurance include Virginia, where an uninsured motor vehicle fee may be paid to the state; New Hampshire, and Mississippi which offers vehicle owners the option to post cash bonds (see below). The clause of Article IV of the U.S. Constitution protects the rights of citizens in each respective state when traveling to another. A motor vehicle owner typically pays insurance companies a monthly fee, often called an insurance monthly payment. The insurance premium a motor vehicle owner pays is usually determined by a variety of factors including the type of covered vehicle, the age and gender of any covered drivers, their driving history, and the location where the vehicle is primarily driven and stored. Credit scores are also taken into consideration. Most insurance companies offer premium discounts based on these factors.
Insurance companies provide a motor vehicle owner with an insurance card for the particular coverage term which is to be kept in the vehicle in the event of a traffic accident as proof of insurance. Recently, states have started passing laws that electronic versions of proof of insurance can now be accepted by the authorities.
