Vehicle insurance (also known as auto insurance, car insurance, or motor insurance) is insurance purchased for cars, trucks, and other vehicles. Its primary use is to provide protection against losses incurred as a result of traffic accidents and against liability that could be incurred in an accident.

In the event of a car accident or damage, auto insurance will protect the owner from the expensive costs involved in fixing the car, other property or another driver's car. Car and auto insurance is essential for all drivers and is required by the law in many states and countries. It is wise to have full coverage automobile insurance, but some drivers can get by on third-party or liability insurance.
