Auto insurance (also known as vehicle 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.Public policies
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.
Coverage levels
Vehicle insurance can cover some or all of the following items:
The insured party (medical payments)
The insured vehicle (physical damage)
Third parties (car and people, property damage and bodily injury)
Third party, fire and theft
In some jurisdictions coverage for injuries to persons riding in the insured vehicle is available without regard to fault in the auto accident (No Fault Auto Insurance)
Different policies specify the circumstances under which each item is covered. For example, a vehicle can be insured against theft, fire damage, or accident damage independently.
Behavior-based insurance
The use of non-intrusive load monitoring to detect drunk driving and other risky behaviors has been proposed. A US patent application combining this technology with a usage based insurance product to create a new type of behavior based auto insurance product is currently open for public comment on peer to patent.
