"Car insurance is a contractual agreement between an individual or entity owning a vehicle and an insurance company. This agreement provides financial protection to the vehicle owner in situations such as traffic accidents, damage to the vehicle, or legal liabilities resulting from these events." 

In Oklahoma, like in many other states in the United States, it is a legal requirement to have car insurance to drive on the roads. In addition to complying with the law, getting car insurance provides financial security in case of emergencies,as well as the possibility of accessing roadside assistance services and other additional benefits, depending on the specific policy purchased.
