Vehicle insurance (also known as auto insurance, GAP insurance, car insurance, or motor insurance) is insurance purchased for cars, trucks,motorcycles, and other road vehicles. Its primary use is to provide financial protection against physical damage and/or bodily injury resulting from traffic collisions and against liability that could also arise therefrom. The specific terms of vehicle insurance vary with legal regulations in each region. To a lesser degree vehicle insurance may additionally offer financial protection against theft of the vehicle and possibly damage to the vehicle, sustained from things other than traffic collisions.In many jurisdictions it is compulsory to have vehicle insurance before using or keeping a motor vehicle on public roads. Most jurisdictions relate insurance to both the car and the driver, however the degree of each varies greatly.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which is paid through a gasoline tax (petrol tax). This would address issues of uninsured motorists and also charge based on the miles (kilometres) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
